This is one of my top 5 UA-cam channels. Although I am not a mechanic nor work in the auto industry in any capacity I definitely enjoy listening to Mr Kelly and his explanation of CVTs and EV drivetrains.
Professor thank you so much. This is my new favorite video from you. You have done my mind so much ease by showing me under the skin of these hybrids and EV's. I am able to reference for others cause of these too. Thank you so much for your hard work.
Sir.. i am from Pakistan and i just watched your video... i must say that you are an inspiration to me.. you just made this video with so much efforts that even a man with standing posture could not teach us so beautifully and with so much details that you have done... just wanted to say you are great 👍👍👍👍👍👍❤❤❤
Fantastic presentation. Everything was clearly labeled and then explained in concise detail. Your students are blessed to have such a great mentor! Thank you for your dedication to your craft.
This is so detailed and thorough. Thank you for this! I own a prime and I love it but I’m also quite terrified if anything ever happens to this system. This is confirming that I will be relying on specialists at the dealership if this battery system ever needs service. Hopefully it doesn’t and it lasts a looooong time
Thank you for the video! I love all of your videos! Also, a fun fact: the doorman part number for this battery pack is 587-007. And according to the doorman products site page it was used in certain 2009 to 2018 Toyota vehicles and certain 2011 to 2017 Lexus vehicles. Surprisingly you can order replacement packs through at least 1 of the national US auto parts stores with a 2 year warranty. I found out that today.
The other receptacle is likely Mennekes type 2 that is used in Europe. And here in Europe we sometimes call the J1772 type 1. Also in some European countries ,for instance France and Italy, you can find type 3a or type 3c, but for those you have to get an adapter because no cars use it. Type 3a and type 1 support single phase and type 2 and type 3c support three phase. And for DC fast charging we use either CCS Combo type 2 or Chademo.
In addition: The Chinese use different separate AC and DC charging connectors, which are called GB/T according to the GB/T 20234.2-2011 standard. The GB/T AC connector looks quite similar to the European Type2 connector, but is not compatible. The GB/T DC connector has some similarity to the Japanese ChaDeMo connector. So for AC charging there are mainly three different connectors in use worldwide. The Type1 for the US and Japan, the Type2 for Europe both according to the IEC 62196 and GB/T AC for China. Thank you for your great detailed und explained videos! Maybe you can get your hands on a Tesla Model 3 in future as well :)
@WeberAuto don't thank just yet, because apart from the general info on French EV socket formats, the "likely" part is just wrong guessing. On European Prius PHV the left J1772 is replaced by an IEC 62196 Type 2 connector aka Mennekes socket. The right empty space on non-japanese vehicles is just a holder for the left socket cap, as you can perfectly see in this picture from Toyota Europe media site: content.presspage.com/uploads/1523/500_2017-prius-phv-aqua-detail-07.jpg On Japan alone Toyota offers the CHAdeMO quick DC charging option that you mentioned, as depicted on this other picture here: www.priusfreunde.de/portal/images/fbfiles/images/externalcharging_img1.jpg
Thanks for new video! My favorite new tool is a voltage proofing unit sold by Fluke. So you can test your meter before and after testing for absence of power. Runs on 9volt. I just bought Clarity PHEV. Thanks again Jed
I am trying to figure out how I can bury my ID-5100A radio in the rear if the car and grab 12v power. I need a maximum of 15A. Can I grab it from here? 19:11
yes! i don't know if someone already told it but yes, the japanese version of the prius prime (prius phv in japan) has DC quick charging with a CHAdeMo plug :)
WeberAuto yeah. Do you think that a regular Prius prime/PHV that doesn’t have DC charging could be fitted with it aftermarket? Through a Toyota dealership obviously...
That other molded piece in charge plug area also holds the cover for the charge receptacle while charging.. Have always wondered what the battery system looked like and how it functioned in my Prime. Thanks for the excellent tutorial.
Thanks for the great videos about the Prime and other aspects of the Prius Hybrid System. I recently got a Prime, and the owner's manual filled me with lots of FUD about the 12-volt battery. You have answered many of my questions.
My Prius prime was hit on the back door by a car going 75 mph. Thank you for posting this video. The estimator had no idea my car is a plug in hybrid. I think it might be totaled if it hit this battery. The battery is 7500 - 10k
Would you be able to do an in-depth video on the plug-in battery charger at 10:30? I'm curious how it interfaces to the J1772 plug to negotiate charging current, and how it knows the battery SoC to manage charging. The 6.6kW rav4 prime plug-in charger I expect to be similar, but it also has a 1500W inverter located somewhere near or on the same module, so not sure how that charger might be different.
I love you. Sending you good Karma, thank you for being such a knowledgeable and helpful man and sharing it with the world. Much appreciated, taking notes!
Awesome as usual Prof. Kelly. I'm studying this to learn more about what the Rav4 Prime will be like. It sounds like the Rav4 Prime will have a dedicated evaporator to chill battery air, in addition to a heat pump climate system.
Glad to see you back on UA-cam, Professor Kelly! I'll never be a fan of batteries in the passenger compartment or ones cooled with a duct from inside. In an accident that damages the battery and potentially disables or traps the passengers this could quickly go very badly. But high voltage cables inside under the rear seat cushion? Toyota is famous for their engineering but much in this car (including the air cooled charger under the seat) makes this model seem like an afterthought. I do like the battery cells though, packaged like Leaf batteries but easier to get to. I'll will start looking for a Prius PHEV that's been wrapped around a tree. Unfortunately (for me anyway) Prius drivers tend to be very careful. If I find one the cells will be in great shape with those extremely modest use and charging voltages. I do hope you are able to post a tear-down of the Gen 2 Volt drive unit some day. I'll never take one apart. I just want to see a better explanation than GM gives. Interesting Gen 2 Chevy Volt trivia: I rode my motorcycle to work one day last week here in Texas. I left my '18 Volt fully charged outside but plugged in. My wife was surprised to hear the fans and maybe the compressor start while she was outside for a moment in the punishing midday heat. Apparently the battery cooling system will come on when plugged in if the battery exceeds some limit. And again, Glad to have you back.
Very good points regarding HV battery safety. I never really considered the fact that a major screwup with one of these will probably kill you before you hit the ground... and then burn your house to the ground... but it's not like gasoline is much safer lol
Thank you, Professor Kelley,for this video! I have learned several interesting things and particularly about the cooling of the high volt battery intakes from the interior and the actual charger below the rear seats. Also, I have a doubt about the aux battery which is draining after the charging and now with your explanation, as I have understood, that could be a problem with the interior temperature which is usually about 85F-90F. Next time I will measure the amount of drainage at different temperatures and share with you.
I am not taking the battery pack out of my 2020 Prius Prime but dang did I learn somethings to keep my battery cooling optimal that I sure wasn't doing before!
Great as always professor. Seems like Toyota is a lot more forthcoming with its battery capacity - the official literature from Toyota does rate the battery at 8.8 kWh which is pretty bang on with the actual 8.79 kWh on the pack itself. In comparison with the Bolt, despite its significantly larger capacity, is marketed at 60 kWh while its true capacity is actually 57 kWh.
Another great video!! By the way, you encouraged me to buy a savaged Bolt! Going to remove battery pack to use in my solar production. I would like to use it as a whole pack, if you have any suggestions let me know. If you need any spare parts for the Bolt, let me know. Coming to Utah in the fall! Thanks again for your very good videos!
We never heard the battery fans running like you said we would hear. I think that is the problem with my car. Something is very noisy in the rear when going down the freeway. Thank you.
Hi professor, The japanese version of this car has a solar roof option, Does the US model has the harness or port to support this? Also Do you think the battery module can be expanded?
Professor Kelly, as someone has already commented, in Japan there's a J1772 (left) and ChadeMo (right) connectors, in the EU there's a Mennekes (Type 2) connector only, no DC charging option.
I have a 2020 Prime Limited, 3 months old with about 1600 miles on it. It has recently developed a squeak coming from the battery area. I have removed all the plastic parts to be sure it wasn’t that. Anyway, you hear it most when you tweak the chassis by going sideways through a dip in the road... I can only think it sounds like metal on metal... I wonder if this top battery is rubbing against the one below it?? Any ideas? Is it missing some foam padding between the two? What can be done? Thoughts? TIA. 😊
your so knowledgeable and easy to listen to ! thanks, n i just bought one of these and it has a problem with battery charging module. It wont comm on network. what im not sure of is , is it still charging or not >???? but either way , i have to fix it, because theres constant warning on main cluster of hybrid problem... Bummer
@22.12 you mention that the system has a DC to DC converter. Is that a line that is always on or only active when charging? I'd like to add two features to my vehicle without compromising the systems battery sensors. one would be to add a sine wave inverter and pull from Aux battery. This way I could use my vehicle as a temporary generator when necessary. (maybe change the starter to a deep cycle?) second would be to add a small 12v fridge but have it run off the traction battery via a DC to DC step down. This way if the traction battery system does die, the car can still turn on via the 12v starter battery. any thoughts?
I see Weberauto vidéo notifications and I click right away. Thanks for the time you put into these videos it’s very interesting. I wish you could take a VW E golf apart. All theses priuses you have in the shop were they given to the school from the manufacturer ?
Thanks Professor Kelly and W.S.U. for this fascinating video on the Prius Prime that we have owned since last September. We live outside Memphis so I was interested in a comment you made concerning the battery cooler. I have observed that now that the extreme heat has hit our area I frequently get a message when I turn off the vehicle whether I would authorize the use of the air conditioner while the next charging event happens. So to answer your question about whether it is automatically defaulted on I would say not. The battery heater does have an off and on switch in the menu. I don't know if there is a connection but I have not had any success setting the air conditioning to pre condition the cabin at the end of the charging cycle. Others have had the same issue from the online forums. I do keep allowing the car to use the air conditioner to cool at charging but it keeps asking me to allow each time I turn the car off when the climate is hot.
Thank you for sharing, I must have misread the setting description . Maybe it is a Toyota scan tool configured setting. I swear I saw something about that. Have a great day!
Thank you, for the only through explanation of how these batteries are cooled . You are doing a great service to those of us who will not buy this technology until we see the engineers did their job. I am bewildered at Nissan how they could not do at least this minimal cooling that Toyota designed for a battery 1/5 the size? Thanx, again
Professor Kelly, what do you think is possible to install another of the same batteries in Prime? The goal is to increase the number of miles on electricity. What can be the problems when installing the second battery?
Hello, I just had a quick question about where can I find the battery fan filter for a 2022 Toyota Prius nonprime hybrid. I’m trying to find the location of the filter. Thanks
So if the battery becomes too hot and air conditioning is not turned on (or insufficient cooling due to blocked air inlet), will the car disable the battery and use only engine to power the car until the battery temperature has restored?
@@WeberAuto And I also do have another question came before this: Can the car actually run without using the traction battery? If the traction battery went open-circuit somehow, does the car still turn the engine with the 12V battery? If the car cannot power itself without traction battery at all, then it would be certain that the car will never be able to disable the traction battery. (don't know if we can simulate this by removing the fuse inside the service plug and plug it back in)
WE STUDENTS APPRECIATE THIS VALUABLE INFORMATION ABOUT THE EXTRACTION OF THE BATTERY FROM THE PRIUS 2017 PRIME AS WELL AS THE VERIFICATION OF ITS COMPENENTS AS IT SOLVES MANY DOUBTS AND HELPS US TO IMPROVE EVERY DAY.
Thank you professor Kelly for sharing your immense knowledge of hybrid and electric vehicle theory, operation and diagnosis. Can you recommend a book that covers in detail hybrid and electric theory and operation or what textbooks you teach from at WSU? Keep up your amazing teachings!
Very nice video, thank you for your work! I have a question; Can be battery be charged on the Prius plug-in, at a same time as discharging? For example; if you have a fully charged battery in the Prius plug-in, you put the car on a spinning machine (to spin the wheels) get the speed to 65 mph, then plug the car to a charger- 208 or 240 volts. Will the battery be charging ? or perhaps will it slow down the discharge ?
Question for you. I have the '17 Prius Prime Advanced. Do you think they will have an upgrade for them down the road that allows you to put a bigger battery in for more EV distance? I know it will lose more trunk space, but I am willing to give that up for double or even triple the EV distance. Thanks.
Toyota will never do that. It would be a cool thing, but the entire system would need to be changed to make that work. Safety and crashworthiness are issues that would be a problem as well. Best wishes!
John - do you see any other evidence of where the Level 3 charging cables or equipment might reside? Also, do you think it would be an easy retrofit? Would the charging port connect directly to the battery? (DC to DC) Or still go through on onboard charger? I'm wondering if the Japanese battery is any different, or if this US model can be quick charged with the right hardware.
Good questions. I suspect the battery is the same. It would bypass the on-board charger and connect directly to the battery junction block near the contactors. The contactors would need to be programmed to turn on to allow the charge. I doubt you could retrofit since it would require reprogramming several ECUs.
WeberAuto thanks for the insight. I feared some ECU flashing may be required - just some TechStream programming would be luck! Now... to find a wrecked PHV from Japan...
I have 2 Gen 2 and I can just deadlift the battery out but this baby looks like it weighs more than 120lbs. Do you have the actual weight? Also, did I hear that the engine can charge the main battery? If I'm not mistaken, the first Plug-In Prius had a separate battery that had to be charged from an outside source only. The new Prime only has one traction battery so it can be charged by external power OR the engine?
270 lbs of battery weight. The high voltage battery can be charged by the engine in a special mode. All plug-in Prius models (2012-2018) use one high voltage battery
John - in the early 2000s, I was a member of the San Diego Prius Club. We had some unusual opportunities like driving the Prius C prototype. Another prototype was an early plug-in Prius that would only go about 14 miles on a charge. It had two big batteries and one was the normal big traction battery. The plug-in battery was separate and was not chargeable by the main battery. I thought this was normal for all the plug-in hybrids until the Prime? As for all the LION Prii - I don't think I could replace the bad modules like I have in the Gen 2 and 3. Those LION packs don't look like they can be easily taken apart. By the way, I'm surprised you found a Prime battery from a boneyard. I bet that cost the school a small fortune.
Wow, that sounds like it was an interesting opportunity. The prototype plug-in models did have two separate batteries, not production models. The Prime battery from a salvage yard on eBay was a rare find. It had just been posted and I bought it instantly. It was actually listed at a cost that was less than a Gen-2 Prius used battery; incredible deal!
Thank you so much for this detailed demonstration. However, I would like to know the price of this battery for prius prime 2017 and if possible to buy this from Bangladesh?
Awesome video! Thank you very much for this and all of your killer Prius videos! Curious that it took 5 hours to charge at 208V (comparable with 120V charging speeds), when it takes a little over 2 hours at 240V...
It’s been too long! Looking forward for another series! On the charger under the back seat are the AC and DC connectors equal? Can they be plugged wrong by accident? The connectors on the battery for the inverter/motor don’t seem to have any label or differentiating color, how do you know which one is positive?
Thank you! The charger connectors cannot be interchanged, there are slight differences. The large connectors are also different. I had to measure the polarity to determine which one was positive.
Hi something incorrect here I have a 2020 Prius Prime charging at home and at charging station 220v only takes 2 hours can at best get 28 miles other times 24 miles. Why is your charging taking so long? And I am using 6.03 KWh what is up with that also. I would like to hear what the difference is or what. Thanks
the question is why can't we use the battery power to run an alternator to keep recharge also we have 4 wheels running and can use the running power to recharge to

You are most welcome Sir
Professor, thank you for meticulously documenting these HV and EV battery removals. You're the best!
Thank you very much!
Best prof I've ever been trained under!
Thank you very much!
Thanks for another great video, Professor Kelley
Thank you very much!
Fantastic presentation. Everything was clearly labeled and then explained in concise detail. Your students are blessed to have such a great mentor! Thank you for your dedication to your craft.
Nice to see they put a filter on the cooling fan intake. Much easier to clean that than the insides of the battery assembly!
I agree. Long overdue
This is so detailed and thorough. Thank you for this! I own a prime and I love it but I’m also quite terrified if anything ever happens to this system. This is confirming that I will be relying on specialists at the dealership if this battery system ever needs service. Hopefully it doesn’t and it lasts a looooong time

yes! i don't know if someone already told it but yes, the japanese version of the prius prime (prius phv in japan) has DC quick charging with a CHAdeMo plug :)
Yes, thank you very much. That is a great option.
WeberAuto yeah. Do you think that a regular Prius prime/PHV that doesn’t have DC charging could be fitted with it aftermarket? Through a Toyota dealership obviously...

what can I say , your videos are always so good ....still waiting for the Tesla tear down
Thank you very much!
You are such a good teacher, I enjoy your class
Thank you professor. Very good video as always. I am hoping for a video on a first gen Plug-in. 👍

Thank you! That should work well. A small pump could circulate the coolant as needed. Stop by and say hello if you pass through.
Thanks for the great info, as always!
We never heard the battery fans running like you said we would hear. I think that is the problem with my car. Something is very noisy in the rear when going down the freeway. Thank you.
Hi I know it's a little late but apparently In Japan you can get a Prius prime with a chademo connecter which is DC fast. Thought that was interesting
Hi professor,
The japanese version of this car has a solar roof option, Does the US model has the harness or port to support this? Also Do you think the battery module can be expanded?
Hi, it's a pleasure to see you again, what is the weight of this hybrid battery?
Thank you! About 275 Lbs
sir can i use a inverter to rum heater in my house during a blackout.my prius is a 2018
Professor Kelly, as someone has already commented, in Japan there's a J1772 (left) and ChadeMo (right) connectors, in the EU there's a Mennekes (Type 2) connector only, no DC charging option.
Thank you very much! It is good to get valuable feedback like this!

@22.12 you mention that the system has a DC to DC converter.
Is that a line that is always on or only active when charging?
I'd like to add two features to my vehicle without compromising the systems battery sensors.
one would be to add a sine wave inverter and pull from Aux battery. This way I could use my vehicle as a temporary generator when necessary. (maybe change the starter to a deep cycle?)
second would be to add a small 12v fridge but have it run off the traction battery via a DC to DC step down. This way if the traction battery system does die, the car can still turn on via the 12v starter battery.
any thoughts?
I see Weberauto vidéo notifications and I click right away. Thanks for the time you put into these videos it’s very interesting. I wish you could take a VW E golf apart. All theses priuses you have in the shop were they given to the school from the manufacturer ?
Thank you! No, we purchased two of them
Excellent presentation.
Thank you !
Thanks Professor Kelly and W.S.U. for this fascinating video on the Prius Prime that we have owned since last September. We live outside Memphis so I was interested in a comment you made concerning the battery cooler. I have observed that now that the extreme heat has hit our area I frequently get a message when I turn off the vehicle whether I would authorize the use of the air conditioner while the next charging event happens. So to answer your question about whether it is automatically defaulted on I would say not. The battery heater does have an off and on switch in the menu. I don't know if there is a connection but I have not had any success setting the air conditioning to pre condition the cabin at the end of the charging cycle. Others have had the same issue from the online forums. I do keep allowing the car to use the air conditioner to cool at charging but it keeps asking me to allow each time I turn the car off when the climate is hot.
Thank you for sharing, I must have misread the setting description . Maybe it is a Toyota scan tool configured setting. I swear I saw something about that. Have a great day!
Thank you, for the only through explanation of how these batteries are cooled . You are doing a great service to those of us who will not buy this technology until we see the engineers did their job. I am bewildered at Nissan how they could not do at least this minimal cooling that Toyota designed for a battery 1/5 the size? Thanx, again
Thanks Professor Kelly. Regards, Ramish.
Thank you!
Génial! Vos explications sont très claires. Merci pour cette vidéo!
Excellent video professor. Wow, that battery cooling system certainly ruined my dream of owning a convertible, (drop top), Prius.
Thanks, Toyota warns that any large volumes of liquid spilling in the trunk/hatch area can ruin the battery
Professor Kelly, what do you think is possible to install another of the same batteries in Prime? The goal is to increase the number of miles on electricity. What can be the problems when installing the second battery?
Hello, I just had a quick question about where can I find the battery fan filter for a 2022 Toyota Prius nonprime hybrid. I’m trying to find the location of the filter. Thanks
So if the battery becomes too hot and air conditioning is not turned on (or insufficient cooling due to blocked air inlet), will the car disable the battery and use only engine to power the car until the battery temperature has restored?
Good question, I do not know the answer
@@WeberAuto And I also do have another question came before this: Can the car actually run without using the traction battery?
If the traction battery went open-circuit somehow, does the car still turn the engine with the 12V battery?
If the car cannot power itself without traction battery at all, then it would be certain that the car will never be able to disable the traction battery.
(don't know if we can simulate this by removing the fuse inside the service plug and plug it back in)
@@yrr0r244 No, it will not start or run. Never pull the service plug with the car on, it can result in a DC arc flash and a fire.
WE STUDENTS APPRECIATE THIS VALUABLE INFORMATION ABOUT THE EXTRACTION OF THE BATTERY FROM THE PRIUS 2017 PRIME AS WELL AS THE VERIFICATION OF ITS COMPENENTS AS IT SOLVES MANY DOUBTS AND HELPS US TO IMPROVE EVERY DAY.
Thank you professor Kelly for sharing your immense knowledge of hybrid and electric vehicle theory, operation and diagnosis. Can you recommend a book that covers in detail hybrid and electric theory and operation or what textbooks you teach from at WSU? Keep up your amazing teachings!
Great video as always:) thank you professor
Thank you very much!
Very nice video, thank you for your work!
I have a question;
Can be battery be charged on the Prius plug-in, at a same time as discharging? For example; if you have a fully charged battery in the Prius plug-in, you put the car on a spinning machine (to spin the wheels) get the speed to 65 mph, then plug the car to a charger- 208 or 240 volts. Will the battery be charging ? or perhaps will it slow down the discharge ?
No, the car must be stopped while charging. It will not even power on to the "Ready mode" if the charger is plugged in.
WeberAuto, Ok, thank you for your reply......
Thank you for a great explanation video!
Can this battery be used for solar application.
Thanks for this. Please can you also do one for the earlier Prius PHV, the 2012-16 gen3 Prius PHV, if you are able.
Thank you. That would be fun
Question for you. I have the '17 Prius Prime Advanced. Do you think they will have an upgrade for them down the road that allows you to put a bigger battery in for more EV distance? I know it will lose more trunk space, but I am willing to give that up for double or even triple the EV distance. Thanks.
Toyota will never do that. It would be a cool thing, but the entire system would need to be changed to make that work. Safety and crashworthiness are issues that would be a problem as well. Best wishes!
John - do you see any other evidence of where the Level 3 charging cables or equipment might reside?
Also, do you think it would be an easy retrofit? Would the charging port connect directly to the battery? (DC to DC) Or still go through on onboard charger? I'm wondering if the Japanese battery is any different, or if this US model can be quick charged with the right hardware.
Good questions. I suspect the battery is the same. It would bypass the on-board charger and connect directly to the battery junction block near the contactors. The contactors would need to be programmed to turn on to allow the charge. I doubt you could retrofit since it would require reprogramming several ECUs.
WeberAuto thanks for the insight. I feared some ECU flashing may be required - just some TechStream programming would be luck!
Now... to find a wrecked PHV from Japan...
Thank you sir for sharing your knowledge.
Thank you!
Excellent video - what was the scanning tool/software that you used to extract the battery cell voltage information?
Thank you. I was using Toyota's Techstream software
Did you ever do a teardown of the prior gen US Prius Plug in model? Have not seen here.
No, I have not had access to one. Thank you
Great lesson!! Thanks!
Thank you very much!
Another excellent video on Prius Prime battery technology. Thanks! From a Snap-on retiree - cool to see some of our products used here.
I would love to come learn form you, greetings from Mississippi.
hi profesor why the cell is only half of the big box is extremely big to the small cell
There are 95 cells in 5 modules. It fills the entire box
Dr. so the maxium charging voltage is only up 3.95v per cell? instead of 4.2v. very conservative is toyota.
Yes, very conservative.
A important lesson.from toyota
Hi can you install prime battery into prius? Thanks
no
Please do you have video available for sensor parking system for Prius prime
Thanks for your feedback!
thanks for sharing your expertise ...
Thank you!
I read that there is a space under the battery of an inch or two. Is that true? If so, any idea why?
Yes, for liquid capture if spillage occurs
I have 2 Gen 2 and I can just deadlift the battery out but this baby looks like it weighs more than 120lbs. Do you have the actual weight? Also, did I hear that the engine can charge the main battery? If I'm not mistaken, the first Plug-In Prius had a separate battery that had to be charged from an outside source only. The new Prime only has one traction battery so it can be charged by external power OR the engine?
270 lbs of battery weight. The high voltage battery can be charged by the engine in a special mode. All plug-in Prius models (2012-2018) use one high voltage battery
John - in the early 2000s, I was a member of the San Diego Prius Club. We had some unusual opportunities like driving the Prius C prototype. Another prototype was an early plug-in Prius that would only go about 14 miles on a charge. It had two big batteries and one was the normal big traction battery. The plug-in battery was separate and was not chargeable by the main battery. I thought this was normal for all the plug-in hybrids until the Prime? As for all the LION Prii - I don't think I could replace the bad modules like I have in the Gen 2 and 3. Those LION packs don't look like they can be easily taken apart. By the way, I'm surprised you found a Prime battery from a boneyard. I bet that cost the school a small fortune.
Wow, that sounds like it was an interesting opportunity. The prototype plug-in models did have two separate batteries, not production models. The Prime battery from a salvage yard on eBay was a rare find. It had just been posted and I bought it instantly. It was actually listed at a cost that was less than a Gen-2 Prius used battery; incredible deal!
You absolutely STOLE that battery. What Luck!
May I inquire if it is possible to upgrade to a battery capacity exceeding 8.79kWh?
Thank you so much for this detailed demonstration. However, I would like to know the price of this battery for prius prime 2017 and if possible to buy this from Bangladesh?
Thank you very much!
Awesome video! Thank you very much for this and all of your killer Prius videos!
Curious that it took 5 hours to charge at 208V (comparable with 120V charging speeds), when it takes a little over 2 hours at 240V...
Thank you very much! I wonder if there is a charge rate setting that is turned down on this Prius Prime. I will investigate further.
Thank you for the video. Can I feed my house out of this vehicle in case of a lack of electrical power from the hydro grid?
Hello professor
Is there a difference between japanes prius phv 2018 battery and USA prius phv or they r same ?
Is it possible to add an ADDITIONAL lithium ion battery to a Toyota Prius prime that's already equipped with a lithium battery for additional range?
It’s been too long! Looking forward for another series!
On the charger under the back seat are the AC and DC connectors equal? Can they be plugged wrong by accident? The connectors on the battery for the inverter/motor don’t seem to have any label or differentiating color, how do you know which one is positive?
Thank you! The charger connectors cannot be interchanged, there are slight differences. The large connectors are also different. I had to measure the polarity to determine which one was positive.
Hi something incorrect here I have a 2020 Prius Prime charging at home and at charging station 220v only takes 2 hours can at best get 28 miles other times 24 miles. Why is your charging taking so long? And I am using 6.03 KWh what is up with that also. I would like to hear what the difference is or what. Thanks
I found out that the car was set to an 8 amp charge. After changing it, it was faster like yours. Thanks for watching
I know this is an old video but how is the battery protected in the event of a rear end collision?
the question is why can't we use the battery power to run an alternator to keep recharge also we have 4 wheels running and can use the running power to recharge to
The charging connector also has a communication cables bia can + and can-.
It can on some applications, but not this one. Thanks for watching
