Which Electric Motor for our EV JEEP Conversion?
Вставка
- Опубліковано 14 чер 2024
- In this video, you learn about which E-motor and inverter we are choosing for our '99 Jeep Wrangler conversion. Some basic RPM, gearing calculations starting from the vehicle top speed guide you towards our Cascadia Motion E-Drive system with a gearbox. We also prepared a weight analysis of the Jeep before and after conversion, so we know how many batteries we can use. Special star guest in this video: my cat, Billy 😂.

Easily the most informative ev conversion series that I've seen so far and clearly explained! Great work!
Thank you SOOOO much, makes me super happy to read that. I am putting lots of effort into these videos and love reading a response like this! 😻
I agree with Brian. These are great videos what actually EXPLAIN what calcs and considerations you need to think about. Thank you Veronica! Best series I've found yet.
My Jeep came out at 4360 pounds. About 800-1000 pounds over stock. I have a good idea how far my Jeep will go with my battery but I look forward to seeing how far you think it will go. Great job, guys!
Wow....I have watched plenty of videos on this topic, but never never ever...have I seen more comprehensive than you did. Congratulations
Wow thank you so much for that feedback! That makes me extremely happy!
Anybody doing an EV conversion right now? Which E-motor, inverter, batteries are you using? What do you think about the weight analysis and what will the electric range be? Let me know what you are up to and what you think about our choices! 😊🙌🔋
At a typical energy density of about 0.2 kWh/kg for bare modules, 250 kg for the complete battery implies less than 50 kWh, which is enough for a functional Jeep... the bigger problem may be finding space for the module. At a density for the Mach E's LG modules of about 0.36 kWh/L, 50 kWh would be about 140 L... plus all of the mounting, wiring, and enclosure space. The range with 50 kWh while pushing this barn door might be about 200 km. It will be interesting to see how it actually works out.
Yes! I'm currently converting my 1981 DeLorean into an EV. For all components, I went with a 2019 Chevy Bolt EV - so I have 66kWh of brand new LG Chem batteries, a 150kW electric motor with integrated single-speed transmission and differential, and the inverter is the one straight from the car with matched specs. Your weight analysis looks good to me! I think 250kg would translate to about 55kWh and a range of around 165 miles (estimating, since the Cd*A is probably pretty bad on a Jeep, so maybe ~3 miles/kWh). Be sure to take into account how much your battery boxes will weight, cooling plates, all that stuff. I think it's easy to add up without realizing it.
Electrified Veronika, you and Don have been very busy. Loved the video, very nice job on educating everyone on the process of selecting the E-Motor and other components for your Jeep. Very interesting your presentation was excellent.
Thank you, so glad to hear that!
Amazing video and series. Thanks a lot for these. The 3d scans and printing was an amazing add on. I'm barely starting my project design. But attempting to convert a 2005 Jeep Grand Cherokee. Will look forward to your videos and what you have on your web page. Thanks a lot for these!
Thank you for the feedback. I am restructuring my website right now. Give me a couple more weeks and all the content will be up there!
Hello from Wisconsin. Glad I found your channel.
That must have been the local news yesterday ☺️☺️ thanks for joining this adventure ☺️🙌
This is your most well done video to date....awesome....great job guys.
Wow, thank you! That's great to hear. We are learning with every video!
Another interesting and clever conversion by 'Electric Classic Cars' used a tesla unit located where original transfer case is, So the drive shafts to fwd and aft axles come out of Tesla unit where Left and Right wheel used to be. I don't know details about ring & Pinion Reduction in axles was dealt with - they must have done something for that.
That was well put together. Thanks for the effort. Cute cate!
Thank you! Hehe, I brought the cat from Austria, he is already 14 years old but fit enough to jump around in UA-cam videos!
This is a great project, thanks for letting me follow along!
Thank you for being part of the adventure! ☺️💪
Hoch interessante Serie. Freue mich schon auf die nächste Folge. Da bekommt man direkt Lust auf ein eigenes Projekt. Schöne Grüße aus Salzburg
DANKE!! Ich hab noch nie so viel gelernt! Consulting in der Industrie ist eines, aber wirklich selbststaendig durch den OEM Prozess zu gehen, hat schon was 😂
You're both awesome for making these videos.
I'll be doing a Ranger with 4wd about a year from now. Hope I can make such detailed videos as you.
I really appreciate you sharing your process
Would love to watch them!
Thank you, your explanation really helpful
You are awesome guys! thanks for the video :)
Thank you for watching! We are glad you enjoy the videos! ☺️
Very educational. Will follow.
Amazing efforts veronika... We are thankful for you and your husband for this work... And you explain everything in simplicity leaving no room for questions... The best of luck for you... Keep going in this electrfied world 👍
Thank you for your kind words, that makes us very happy! ☺️
Nice work! Looking forward to the next episode.
WOW as an engineer I loved this I want to convert a car soon. Your explanations are crystal clear and extremely easy to follow. Thank you. In closing I also have a cat, a fat lazy Persian
From crazy cat lady to another cat person: THANK YOU SO MUCH. This is great to hear! 😊
Good video, well explained thankyou.
Thank you! I am really glad the content is helpful. More to come soon!
Oh man, that's amazing you were able to get 3d scans and then 3d print them at 1:4 scale!! That's fantastic - super helpful. I tried to use the POP 3d scanner to do the same on my conversion, and it just failed horribly. I could not get any reasonable full-size scan even though I spent about a dozen hours on it.
We wanted to make the components full size as well, but found out that it's too big and takes too much time. We're going to scale the jeep down instead 😂 I really like these 3D prints - they really help me understand what I'm doing and make it very realistic even before you do the actual work.
Great job
Thank you
Thank you!
Interesting contents. Love to see comprehensible explanation and all the conversion process. Conversion exsiting gasoline/diesel/LPI vehicle is good way for upcoming electrified veheicle era, since scrapping all the parts of the vehicles on the road takes huge amount of wastes to deal with. With conversion, like the Jeep's frame, some parts can be still used rather than disposed. Anyway, love to watch video in this channel.
Thank you so much, wholeheartedly agree!
Congratulations for the channel and for the excellent initiative to transform your car into an electric model. I'm from Brazil and I'm very excited to "resurrect" my old car with a similar project. Your videos with technical content have cleared many doubts and helped to understand the path to this. Regarding the choice of engine, I didn't see you mention the power (hp or kW) of the combustion engine and the power of the electric one. Could you clarify if you will address this in any future videos as well, please? Thanks and congratulations again!
Thank you so much! Wonderful to hear about your EV adventures. Our E-motor has 225kW peak, see Cascadia Motion datasheet: cascadiamotion.com/images/catalog/DataSheets/im225.pdf
@@ElectrifiedVeronikawhat is the name of the company that scanned your Jeep?
So many questions...
I want to convert a 2003 Subaru Baja to electric. Should I definitely get a manual tranny over an automatic?
Thanks...
Thanks for the good video. @5:21 .. circumference should be "pi X diameter" . ie.(22/7) X diameter
Spotted it. She got it right on the whiteboard but wrong in the audio.
Yes. I liked this video very much.
So much so, that I shall watch it again.
Looks Kool Electrical Veronika,hi I'm from New Zealand
Greetings to New Zealand! Thanks for watching!
Very well explained the technical aspects of e-drive
Thank you so much! ❤️😊
Congratulations for the channel and all the video series clearly easy to understand, even for me who just wants to learn about electric cars. I have a few questions Dr. veronika, If the battery is replaced by a generator and the engine is still being used, how do we determine which generator to use and what other equipment is needed? does the generator have to be more powerful than the electric motor or vice versa?. in my place hard to find electric batteries and rare charger station. I want to change my car to ev gradually. Thank you very much. 🙏
Great video! Looking to do a similar TJ frame with your suggested motor. Thanks for doing all the math for me!
Will be interested in seeing how you mate the gearbox to the transfer case.
I’ll be following along with your videos and posts on the DIY forum, keep up the great work-
Thank you! I am happy to hear that the content is helpful! I have to admit I am a little bit afraid of the mechanical integration in general, especially gearbox, motor, transfer case 😂 But we'll do it, thanks for sharing our videos! 🙌🔋😊
@@ElectrifiedVeronika You could use a Prius transmission bell house facing forward... engine input shaft locked, using drum brake off a big 4X4 to disengage the front drive by using cable and hydraulic e-brake ` pull up for engaging drive disk* release - down for freewheeling disk* engaged ` a disk* brake between the drum and transmission to let the diff transfer the drive to the rear..... the transmission can give 200+bhp when both MG1 and MG2 are running together an you can chose which MG you want if you make a switchable ECU to control them....
@@ElectrifiedVeronika Fun fact i have around 5000 - 18650 Samsung 26 series 2600mah batteries for my conversion... i also have another 4000 mixed 18650 cells, and 4000NIMH cells all for FREE... and it`s an increasing amount on the 18650s...(my sanity has long gone) the NIMH are going to be for LED garage lights, tools via inverters :):)
I found out your technically and mechanically inclined .
Very helpful thanks .
Thanks! In the process of creating more!!
I love what you guys are doing BUT could you please do a jku next time? Something with more computers.
excellent stuff, great presentation, love the white board I need one of those. Is that a painted surface????? Dennis
Hehe, thank you. Wisconsin's largest whiteboard is actually a foil. Really convenient and also easy to mount and remove! I have a whiteboard in every room haha.
Veronika. Wonderful videos and Loya of respect for you! I tried researching prices for the cascadia motion parts, but no success. So I am very curious will kits like hours cost. I think in a near future, this EV conversions will be the way to go, specially with the actual vehicles costs.
THANK you, very glad you appreciate our content. We paid around 12k for the motor, inverter and on board charger. The idea we have right now is bringing down the conversion cost significantly by REusing more of the parts, for example a motor and inverter from a scrapped Nissan Leaf. Stay tuned for that!
We want to do the same, excellent video!
Amazing, looking forward to seeing your project coming together!
You are amazing 👏
Please make one video on AVL or GT suite for simulation of battery exothermic gas dynamics
There might be something like that coming up, thanks for requesting/suggesting! Stay tuned!
You are very smart.
Im enjoying the series so far but binge-watching the series would be much easier if the playlist was in order
I love your videos. I'm very curious to see what you do about software. Seems like a modern EV runs a lot of software -- Is there open-source code available? Should there be?
Thank you! I am teasing a little bit in the video that just went live. We are going with AEM Battery Management System and Vehicle Control Unit! Programmable.
Hi Dr. Veronika thank you so much for this! Could you please share your excel sheet at 7:47 or a template of it?
Awesome series 👍🏾 How can I possibly obtain the STL files of the ev components you printed?
Sure! You can actually find them right online from Cascaida Motion directly.
Hi Veronika, Excelent series of videos. I´m waiting for see the next one. Can you indicate which are the components selected for your conversionn. I checked the Cascadia web page and is incredible the components and options. Can you indicate the used and the estimated cost of the conversion?. Regards and congratulations
New video is up with a list of all components we ordered so far! ☺️☺️
Great treatment of the calculations surrounding the selection.
In your application, how did the torque off the line with your new 11.19:1 ratio compare with the original first-gear launch? If I have the right data and am computing correctly, the total drive ratio in high first is 14.62:1.
Thanks for the question Brian. Of course the biggest difference with "off the line" torque comes from the fact that the original engine torque curve is VERY different from the electric motor torque curve which has (basically) full torque at 0 rpm. In fact, we are planning on limiting the power delivery at low RPM's so we don't break things as the electric motor, especially with the 3:1 gear reduction, has the ability to supply significant torque at low RPMs.
Thanks, @@ElectrifiedVeronika! I love the channel, especially because you know the math, don't make your living selling conversion kits to other people (mystery bias), and go step by step. I also love that you are rolling in the upper Midwest and that your project will be winter rated and need to deal with the scarcity of charging options outside away from the coasts.
How much does a conversion like this cost? I've been thinking about doing an EV conversion to an old 50's Era pickup truck. Some even come with the engine and transmission already removed! I love your videos btw and you got a sub from me!
Wohoo, thanks for being part of our adventure. Keep watching all the episodes hihi and in Episode 8 in the Q&A session we are answering cost. The conversion we do here is an extreme case - we are working on lower cost options, more to come soon!
May I ask if we can use standard AC 3 phase induction motor in EV project?
I notice that you did not calculate torque for your selected motor on the video. How does the torque from your motor through the transfer case compare to torque of original motor though gears and hi/lo range in 4wd?
do you have links to the motor and battery you used?
i am super interested in doing something like this, i really hope you can do a ton of details for someone who has never done this before.
Great to hear! Let me know what you would like to see! I have never done this before, so I am also a first time converter 😊 Of course it helps to work in the industry..so far everything is completely doable in a garage. We might need to get help for the mechanical integration of the new components. Stay tuned!
Hi EV, can you explain again about the calculation? I want to learn more about that. many thanks
Appreciate!!I am very excited with this interested leassons!how can I get trainings at your place Veronica?
THANK YOU! Watch out for an info event coming up soon, register there and we take it from there!
Thank you so much Velonoca you'll let me know how to register
Ready for that RAV4 conversion ? ___ :) Look forward to my tour in a week or so when I venture across the Cheddar Curtain ( IL and WI border ) ..
Sure, just need to duplicate myself. Which I would love to do 😂
Why do you use an AC motor instead of using Axial flux motor? I heard that they are more efficient about 96%. What about Magnax motors? Another question please, what was the price of the cells were used? And from where you ordered those?
Could you please share the excel sheet that you used?
More video of Billy the cat please!
Haha 😂
Assuming that LiFePO4 batteries are arround 200Watt/h/Kg, it means 200 * 250 (kg left) / 1000 = 50KW/h you can put... yes? (i didnt watched next video, just discovered your channel)
The batteries we are using have NMC cathode chemistry so have a higher energy density than LFP. The overall system will probably have around 60kWh, details to be shared very soon when we have our high voltage battery pack finalized.
could someone show me the numbers on her calculations. Im having a hard time trying to figure it myself. The video is great! im just a little slow when it comes to maths
You weighed the components dry. Did you add the additional weight for oil, coolant, and petrol when setting weight goals?
yes, we did.
Do you have a link to the CAD models you printed?
Sure, these models are publicly available from Cascadia Motion: cascadiamotion.com/productlist/25-integrated-modules/45-im-225 cascadiamotion.com/productlist/22-charging-converters/21-combo cascadiamotion.com/productlist/12-gearboxes/58-sr-309
I am interested in these conversations but all of the videos I’ve seen are one to ten year’s old or older. Are there any updated ones?
Our project started about 2 years ago and we needed to take a break because of a new addition to our family 😊 will have more updates soon
Curious, did you consider the Dana e differential system both 2 wheel drive and 4 wheel drive? I believe they are a straight bolt in replacement .
Thanks for bringing that up! Yes we looked into it. It was much more expensive than the solution we have now and we kind of want to reuse as much as we can. But definitely this is a neat option too and we would not have the mechanical integration "challenges" that we have now.
@@ElectrifiedVeronika thanks for your response. It's a pity you did not include the Dana in your cost analysis.
I'm surprised it was "way" more expensive, as it would hate gearbox requirements as well as reduce your weight limits and provide extra space for batteries etc as well as possibly keeping your weight down lower, perhaps maybe ☺
Did you print the Jeep in quarter-scale to test-fit the components?
That is the plan...
You must be an electrical engineer 🔥🎥
I am a physicist by training, my husband is an electrical engineer hehe
lets go ! lets make another one.... for me 😏
Sure! 🙌☺️ we have two more in the pipeline right now!
It is better in every way to have a regular combustion engine.
Weight of transmission for 2 vs 4 wheel selection is concerning. I wonder if adding a second motor weighs less.
We were thinking about two motors, one in the front, one in the back (see episode 2), but that would have made us get a bigger VCU and of course two inverters..might be something to look into for the next conversion 😊
Hi do you have a parts and supplier list for all the parts?
Yes, I am linking those in all newer videos in the description box.
Goodness you have impeccable penmanship, can you teach me ? :) // And I wanna borrow that 3D printer, wow :) /// Love WI largest whiteboard, have you verified that and called ""Guinness World Records"" ? ____ you could be EVEN More famous ..
One of the few things I did not verify in this project is the whiteboard dimensions 😂 Happy to help guide your conversion 😊
did you take into account the gas tank weight when its full of gas? this could give you extra battery capacity
Yes we did!
@@ElectrifiedVeronika
Fantastic project, as a battery builder, I am very interested to see what range you get and which you chose to go with…
Not sure it's helpful or not? But there is a shop down in Florida doing high end land rover tesla ev conversions. They use a single ldu through the stock transfer case. And electric classic cars from the UK also does similar tesla ev swaps. Maybe either of them could be of some assistance in your build? 🤔
Thank you very much for the suggestions. We know both of these companies and have talked to them. We definitely thought about it but went a different route because we wanted a switchable 2w/4w drive and the Tesla ldu doesn't give us that.
Engineer here... In the RPM, Gearin, speed analysis where you solve step III on the board. That part made absolutely no sense to me. Doesn't mean it was incorrect. seems like you skipped a few steps on the board. Would you mind explaining how you got that wheel RMP of 1084?
1mile=63,360in, 100mph=6,336,000in per hour. If the circumference of the wheel is 97", then each time the wheel goes around once, you cover 97". So, 6,336,000/97=65,319 rotations per hour. Then divide by 60 to change from rotations per hour to RPM, so 1088 (close to 1084...pi*d for a 31" wheel is actually 97.34" not 97"...)...
Do you give break down of cost??
We will - once the project is done 😊🙌
I think that you will need to have at least 30 kWhr of Battery to get almost 100 miles of range. The battery will probably weigh at least 350 kg.
New video went live yesterday - episode 5😊 It's not the final battery concept, but shows you which type of modules we will be using. We are aiming for 60kWh which would be around 250kg right now with our NMC pouch cell modules.
I think a 100 mph in a jeep is crazy fast that any wind road obstacle will make it uncontrollable! If you lighten the jeep it would be even worse, I would look at 85 as a top speed! You're talking about a jeep wrangler, its as aerodynamic as a cow with a suspension of a tractor!
we will not achieve the 100mph because of several losses, I will talk more about this in another future video. I agree, with this Jeep you can't go faster than 70/80, I realized that when we drove back from Nebraska to Milwaukee, 10 hours long, when we bought the Jeep 😂
Was this jeep originally a 4.0?
Yes it was.
You mentioned that two motors separately driving front and rear axles would be very expensive and you worried about matching speeds and retaining 2x vs 4x4 functions. But ... two used Tesla front drive units with inverter would be under $4K and the Cascadia is $12K. Using the complete Tesla drive units would mean saving some weight eliminating the Jeep differentials front and rear, but would require (probably) custom half-shaft drive axles. And syncing the two motors and powering only front or rear to retain 2x and 4x4 funtionality could be done electronically, no ? Even choosing the single-motor configuration you have, a brand new motor used in the Mach-e is $4K and the matching inverter $1800. There are so many used or newer options, I don't think many DIY people would choose the expensive Cascadia products.
We are now starting a conversion with two E-motors - one in front, one in back - and another one with one used Leaf motor - that will significantly bring down the cost. Stay tuned for that! We are really happy with the Cascadia Motion E-drive because everything is integrated and all set up and communication with the VCU is enabled and proven.
My main question to all this conversation is the cost of completion?
Will let everybody know once it’s completed ☺️
I am converting my Hyundai Genesis coupe so wish me luck
Wohoo all the best! Let us know how it goes! ☺️
thats not a 1990 jeep yj wrangler frame and suspension, its a tj suspension. the yj has leaf springs
Choose a motor that has a top RPM of about15 to 25% higher than your desired top RPM for safety.
I am planning to convert my 1978 Jeep wagoneer into an electric EV
100 mph is ridiculous for a Jeep and achieving it will greatly reduce your rang. Probably 80-85 should be max and even that is optimistic.
I would like to work there? Hi Veronica! Everything is great, the only problem is that I can't follow you because you are too beautiful, I have to repeat.
Last video prior you said you use dc ac converter this one you said dc to dc converter…lol yall really winging this huh, i can respect a fake it till you make it drive..but i wont be watching any more cause im an engineer and this is super useless information yall are doing it wrong.
Hey engineer, sorry you seem to be confused about this. I am getting a combined on board chargers plus dc/dc converter. The on board charger converts ac to dc when getting power from an ac source (like a level 2 charger) and the dc to dc converts the high voltage bus from the HV battery down to the 12V needed by many parts of the vehicle and to charge the 12V battery. And then dc to ac is the vehicle inverter for the traction motor. Hope this clarifies it, more to come soon in case you are still interested.
@@ElectrifiedVeronika I hope he is not interested and is gone...
