Even though you acknowledge this as mostly impractical, it's still good that you're testing out such concepts. Thinking outside the box is how new concepts are discovered.
I get a smile out of the fact that this basically a really scaled up version of using a portable USB battery pack you carry around to charge your cell phone.
Although this is an older video, the portable charging concept is a good one. In 2022 the tech that can be applied to portable power sources has improved. An optimized design would now doubt reduce some of inefficiencies.
Honda EU2200 filled with 0.95 gallons of gas and a 3rd party 16 amp level one charger and you're good to go assuming you really only need this in the winter (another drawback with the Goal Zero). $1100 for generator and $200 for the charge controller.
Since the voice sound is weak because a smartphone is used at a distance as a camera with no mike plugged in, it's a reason not to add a free-of-charge "music" on top of it !
I really hate background music in how-to videos. The sound quality in this vid is really bad. It's already hard to hear this guy's voice so HEY, LET's put some BACKGROUND MUSIC in! Bad idea. Stahp.
The biggest downfall is the charge rate. If I had a towing company and I was going to cater to EV charging, I would set up 2 powerwalls in my truck. This would give me a total charge rate of 10kw and a total usable transfer of 26kwh or enough for about 70 miles. If I could manage 4 powerwalls in the truck, I could drastically reduce my time on station by charging the car at it's max AC rate of 15-18kw.
I was hoping to use a solution like this for my Chevy Volt. Apartment living isn't conducive to charging but... I'll keep looking for options. Thanks for this!
Interesting - I see there is now a 6000x version. The use case I'm thinking of is for an Electric Campervan (RV). Being able to charge up one of these from Solar PV on the roof (or laying out by the van) during the day, then dropping 5.5kWh into the main traction battery every evening could give 20 miles range.
Totally agree, which is why a recovery service would have one or more these units to assist those needing a boost on the side of the road. Much better to add 3-4 miles on the side of the road and drive to a charging station vs getting a tow. The AAA could carry them for its members (of which I am one). One model would be you rent one for the day. They bring it to you get you charging and you return the unit the next day.
99.99% of the time you're going to be more than 3-4 miles from a charger, and even if you're not, it's going to take hours to charge that. So, being towed is cheaper and faster, for you probably unles you get towed 10+ times, and most definitely for AAA. A generator would be cheaper and have more use cases as well as being able to provide more range.
@Rod Rye 87.24% of statistics are made up. Statistics aside, as I am driving my LEAF I see the nearby charge stations on its nav screen. I can assure you I am within a mile of a charge point very frequently. Certainly more than the 0.01% of the time you attribute. We can be more specific about how long it will take to charge 3-4 miles. At 120v the charge rate will be 1.44 kW. If you get 4 miles per kWh (250 Wh per mile) then it will take 1/1.44 = 0.69 hrs or 41 minutes to add 4 miles of charge. If you are 2 miles from the closest charge point then you could move on after 25 minutes. Not quite the "hours" as you suggest.
I just bought a 2019 Ford Fusion Energy plug in Hybrid with a 9 kwh battery. I'm guessing something like this could be good as I live in a condo and don't have any out door out lets. Could charge the device in doors then bring it out to charge the car. Doable?
Put a little Honda EU2000i or EU2200i in that same cubby hole. It will put out a constant 1600/1800 watts(depending on 2000/2200 model) for at least 4 hours on 1 gallon of gas. That’s 8-9 kWh vs the 3kwh your getting from that battery. I’ve carried the Honda 2000 in my Tahoe before and it never leaked or spilled gas. It has a shut off valve on the fuel cap vent.
I'm looking at getting the 2020 Subaru Crosstrek Hybrid. It plugs into a standard 110v plug. I live in an apartment condo with no available plugins in the underground parkade. Is there any portable device that would charge the car overnight?
thanks for this, I have a smaller Goal Zero Yeti 1000 but camp for several days with a boulder 200W solar briefcase. I'd like to try this with my Chevy Bolt EV. How did you make the Ground Fault Bypass? Can you buy a bypass like that? I can only find the "cheater plugs" that don't work.
Does that Yeti have a DC out? A DC to DC conversion would be more efficient. I think however, it would be just better to have a compact Honda 2K inverter generator. Its smaller, and has a vent seal, so you can carry it in your car to charge your car. The Honda has a 240VAC, so it will charge near level 2 rate.
anybody know if i can use a smaller 1000 watt portable battery to charge a smaller ev like a Smart fortwo electric car that usually uses a level 1 or 2 charger?
Just short the neutral and ground connectors. Not really much to show. A wire from neutral to ground. This can be dangerous if anything goes wrong with the electronics, so use at your own risk.
I'm wondering if someone could use this method to trickle charge their battery during the winter to keep it warm if they don't have access to a home charger. I'll be getting a Model 3 in the next few months and I live in an apartment so I may try this out during the winter months or on extremely cold days/nights.
I have a C-Max Energi and there is no charger where I work. I've been trying to find some way to charge the car while I'm at work, ideally solar since I'm in Florida and there is plenty of sun, even if it gets me a few EV miles a day that would be beneficial. Any recommendations? Not sure if it makes sense for me to get a battery like this, charge it at work overnight and then take it outside and plug the car in.
Its' 2019 - current price of Goal zero 3kwh battery is over $3k - $1k per kwh But current trading shows lithium ion wholesale at $0.14k per kWh this year. That is one overpriced battery pack. (By comparison if 74kwh model 3 Tesla was priced at Goal zero level the battery itself would be almost twice what the car costs)
I like the idea but think about the added weight of the battery and the effect that will have on the range. It’s like having an additional person in the car. Fine if you leave the battery at your destination and just wheel it out. For areas where there’s no AC you could complement it with solar.
Also you can get 12v 200ah (2.4kwh) battery’s online for around $300. You could prob put two in that little spot and add a 2000w pure sign wave inverter in there as well. You would come in for under a $1000 bucks. That little yeti is 3 times that expensive. And I think you could charge at a little higher rate than that yeti.
I was thinking about this, as a cons on buying the goal zero 1400 lithium. I did not understand the ground bypass, can you point me to a diagram ? I was thinking to put a cable directly to the ground pin and a nail to the ground or something like that. Thanks
As silly as this seems, if you're in some sort of situation where you need portable energy storage for driving around off-grid, I don't see any logical problem with using a small inverter generator. Having an EV doesn't make you a gas-vegan. You still get the same or better fuel economy than a normal car for the quantity of fuel since the generator will operate continuously at it's peak efficiency, and most small inverter generators are only about 50 lbs, not adding a great deal of weight to your car. A 10 hour overnight charge with an inverter generator would yield about 70-80 km of range. You're not going to be driving across the backroads of the entire country with that kind of power delivery, but it's certainly an alright way to artificially extent your vehicle range if you wanted to do some back-road adventuring and camping. Just a thought.
I see lots of people on youtube building home made free energy using dc motors with an ac converter and i wondering if a generator could be made strong enought to handle the tesler charge and i f the generator can be installed directly in the trunk or front hood of the care.
Good test. I predict all road side services (AAA and the like) will have these if they don't already. Juice you up and enable you to drive to a level 2 charging station or home, whichever is closer.
I drive a Kia Soul with only a 34 Kwh battery , I wonder if the 1400 yeti would work for me , Goal Zero needs to double their capacity and make it a little smaller , this could totally help if it was slightly better
i think the benefit would be for camping , and for photographers and how I use it ... I use a lighter adapter and recharge drone batteries and camera batteries , and then camping I use lights and power all sorts of stuff with my Electric car , like my electric car is a power generator .... but with a yeti would be worth it to have just to power all my gear and not use the cars energy to charge my gear and power my stuff and just save the range.
My use case would be camping. If I had a solar panel and was camping and if I was there for a few days to charge up the electric car for the return trip
The $2400 pricetag is insanely high for a 3kWHr pack, even considering that it has fairly true sine wave output and a lot of output options. But the concept of using an add-on pack for long trips is not stupid. If EVs were designed to use trailer mounted range extension battery packs, a recharging stop that currently takes way too long could be as quick as filling up a gas tank... if it was just a matter of exchanging a depleted battery pack trailer for a fully charged one, which would be a lot more feasible than quickly exchanging on-board battery packs (an idea that Tesla toyed with but has now abandoned). Even the idea of using an engine-driven generator to recharge a pure EV is not stupid, nor is it a new idea. Some early EVs (including the tZero, built by AC Propulsion, which became Tesla), had optional generators ('range extending trailers') to allow long trips without lengthy recharging stops.
I am interested in affixing flexible low profile solar panels to the top of a EV. Bypassing all these inverters is the key to better efficiency but then you have to hack car or do something sketchy and void warranty. This goal zero solution (or a different setup from another brand) is actually the only practical way to not mess with the car charge interface itself. Anyone have any other suggestions? Without hacking the car you need to have SOMETHING like this so the car charger works normally.
this seems like a fairly weight inefficient solution. electric airplane batteries are smaller than that 3kWh battery and store 10kWh, plus they are replaceable. you should look for an inverter that can be attached to swappable li-po batteries and you could add another 100km to your range for the weight of 3 of these.
YES! I have the Goal Zero Yeti 400 Lithium. It is designed to have solar panels (or wall / car inverter) plugged in at same time as you are drawing power from it. Display on Goal Zero constantly gives you a live update of draw vs input, expected depletion, or full time, wattage in / out etc.
This is a great idea/concept. I'd like to get a plug-in hybrid but the issue I have to get the costs down is that I can't charge the car using a wall charger due to the layout of our house and where our parking space is, so looking into portable battery charging or standalone solar power
+Chris Darroch like I state in the video in the wrap up, it doesn't make sense unless you are simply using it to rescue an EV that has run out of juice. Like Have Someone Else bring it to you only in the occasion that you happened to be stuck somewhere.
You did imply at the end that it could be a drag on efficiency and that it certainly would if you were to drive "a ton of miles".......................This still implies that somebody might still actually choose, or have some option, to carry the battery in their car (not only for rescue situations). Seems that you didn't want to fully admit that the idea is a non starter, apart from rescue situations.
The Tesla Cybertruck and the Rivian R1S and R1T will come with regular electrical outlets. I think it would be fun to see if you could charge an EV...with another EV.
Thanks for the effort.you helped show me that it doesn't make sense to buy at this point in time. From what I see either go with the Tesla or a hybrid for those longer ranges.
I think it’s probably a better idea to remove weight from the car, get rid of the back seats, carpeting and anything else you can think of to get better range. Make it lighter.
in india with a lot of power outages in smaller towns , many ppl have a inverter with battery at home. Typically a 150 ah 220 v inverter battery setup costs 15000 Rupees, that's 185 usd. the battery is 12 volts , 150 ah at 12 volts equals 1.8 kwh . around 600 watts power rating. So a 300 ah 800 w battery setup won't cost more than 40000 Rupees. That's 500 usd. Or use a pb acid battery , even cheaper. Every IC car has one...
I wonder if the Inergy Kodiak model could do a better job? Either way it kind of proves that this model is not reliable for RV users looking to ditch their gas generators.
2021-04-14: Thanks! 3 1/2 years later, I’m guessing there are better back up units. I’m adjusting to the possibility I could live long enough to be driving electric.
Using it as a charger is a waste because of inverter loss and cable resistance. If you could bypass the car battery and plug the Yeti into the car directly. Then you’d have something.
I agree that as a DIY solution this isn't practical. What I do wonder though is what if EV manufacturers made vehicles with bigger boot (trunk) space (and or fronk space) and made a battery pack to fit into that space. you saw with the Tesla that you could fit 2 x 3kwh batteries into the under-trunk space, and they were not even designed for it, a battery pack designed to fit there might well get 10kwh in. this would be especially useful for low budget EV's. Imagine an Ioniq with the ability to increase the battery from 28kwh to 38kwh, the highway range goes from 200km (124 miles) to 260km (161 miles), (assuming efficiency loss of 16%ish). That could easily make the difference of being able to make the next charger or not on a road trip.
It’s interesting as an experiment but in terms of efficiency it raises the point that if you did run out of power it would cost you less and take less time to call out road side assistance and be towed to the nearest rapid charger AND charge your car. You could do all of that for a lot less than the price of your portable battery and in less time probably.
Awesome... was looking at doing this, one thought. How about throwing the GoalZero 200w solar package on the roof... would it continuously charge?. Like a mini mobile solar station thats like 5000 dollars haha
Nice video but you speak about power in kWh which is live speaking about speed in miles. We need accurate words in videos like this. Power in W, Energy consumption in kWh and Capacity (available energy) in Ah.
Even though you acknowledge this as mostly impractical, it's still good that you're testing out such concepts. Thinking outside the box is how new concepts are discovered.
I get a smile out of the fact that this basically a really scaled up version of using a portable USB battery pack you carry around to charge your cell phone.
Except most portable battery packs can charge your phone to 100% at least once, most of the time more than once. This is much less practical.
What would the cost be to charge the generator up to full?
Or two glass matt batteries and a power inverter. More power and cheaper
This experiment is amazing! thank you for saving me thousands of dollars to do the test myself!
Although this is an older video, the portable charging concept is a good one. In 2022 the tech that can be applied to portable power sources has improved. An optimized design would now doubt reduce some of inefficiencies.

Nice test, thank you. As a suggestion PLEASE turn off the irritating music, 😆
the music isn't as irritating as sound quality, i heard passing cars (and planes better) and winds than this guy talking
Since the voice sound is weak because a smartphone is used at a distance as a camera with no mike plugged in, it's a reason not to add a free-of-charge "music" on top of it !
If your hearing is as bad as mine, this video is useless. I'd love to know what's going on, but can't hear the speech clearly enough.
I really hate background music in how-to videos. The sound quality in this vid is really bad. It's already hard to hear this guy's voice so HEY, LET's put some BACKGROUND MUSIC in! Bad idea. Stahp.
spacep0d
Simple solution. Make your own video, or stfu!
So wait what did you use to bypass the ground fault issue ?
The biggest downfall is the charge rate.
If I had a towing company and I was going to cater to EV charging, I would set up 2 powerwalls in my truck. This would give me a total charge rate of 10kw and a total usable transfer of 26kwh or enough for about 70 miles. If I could manage 4 powerwalls in the truck, I could drastically reduce my time on station by charging the car at it's max AC rate of 15-18kw.
I was hoping to use a solution like this for my Chevy Volt. Apartment living isn't conducive to charging but... I'll keep looking for options. Thanks for this!
I really wish there was an easy way to add batteries to its native battery, I would remove my 2nd row of seats for sure!
Interesting - I see there is now a 6000x version. The use case I'm thinking of is for an Electric Campervan (RV). Being able to charge up one of these from Solar PV on the roof (or laying out by the van) during the day, then dropping 5.5kWh into the main traction battery every evening could give 20 miles range.
Excellent, the three thousand dollar battery supply was able to pump in roughly 30 cents of electricity... good to know.
Thanks for the video!! Would you mind showing how you wired the blue box to get the ground to work??
For use as a recovery emergency situation is the best use case. Could save having to get a tow.
Jean-Pierre White waste of energy lugging it around for an unlikely event if planning ahead
Totally agree, which is why a recovery service would have one or more these units to assist those needing a boost on the side of the road. Much better to add 3-4 miles on the side of the road and drive to a charging station vs getting a tow. The AAA could carry them for its members (of which I am one).

Rod Rye
Don't forget regular outlets. Unless in the middle of nowhere there should be an outlet within a mile.
How did you created the ground for the car charger?It's safe to connect directly the Neutral to Ground wire? Is there other approach for this?
I just bought a 2019 Ford Fusion Energy plug in Hybrid with a 9 kwh battery. I'm guessing something like this could be good as I live in a condo and don't have any out door out lets. Could charge the device in doors then bring it out to charge the car. Doable?
Put a little Honda EU2000i or EU2200i in that same cubby hole. It will put out a constant 1600/1800 watts(depending on 2000/2200 model) for at least 4 hours on 1 gallon of gas.
That’s 8-9 kWh vs the 3kwh your getting from that battery. I’ve carried the Honda 2000 in my Tahoe before and it never leaked or spilled gas. It has a shut off valve on the fuel cap vent.
So you could keep it around like a gas can like a little $3000 3/4 gallon equivalent 68lb gas can
33.7 Kwh = the energy in one gallon of gas, so more like a 1/12 gallon 68lb gas can
@@selmateacher7 you get about 6 miles out of it, so if you compare it to a gas car, maybe 1/4 a gallon worth of gas. 1/8 if compared to a prius.
How long do you take to fully discharge a fully charged Yeti 3000 ?
I'm looking at getting the 2020 Subaru Crosstrek Hybrid. It plugs into a standard 110v plug. I live in an apartment condo with no available plugins in the underground parkade. Is there any portable device that would charge the car overnight?
Man what happen to the charger at minute 6:50 ?
can you move the bmw while its plugged in?
Hi, the wind noise is bothering as I can hardly hear you by friend
thanks for this, I have a smaller Goal Zero Yeti 1000 but camp for several days with a boulder 200W solar briefcase. I'd like to try this with my Chevy Bolt EV. How did you make the Ground Fault Bypass? Can you buy a bypass like that? I can only find the "cheater plugs" that don't work.
What would be great, is a power supply unit that would be "gangable" and plug directly into the ccs or chaDEmo port.
It seems that the slower charging speed may increase battery capacity which may somewhat make up for inefficiencies.
Does that Yeti have a DC out? A DC to DC conversion would be more efficient. I think however, it would be just better to have a compact Honda 2K inverter generator. Its smaller, and has a vent seal, so you can carry it in your car to charge your car. The Honda has a 240VAC, so it will charge near level 2 rate.

Just short the neutral and ground connectors. Not really much to show. A wire from neutral to ground. This can be dangerous if anything goes wrong with the electronics, so use at your own risk.
Did you ever find a way for it to work on the tesla? I have this same generator and it wouldn't work for me because it said it wasn't grounded.
I'm wondering if someone could use this method to trickle charge their battery during the winter to keep it warm if they don't have access to a home charger.

Could you Hook up solar panels to the battery?
Did I miss it, or does your video not tell us how long it took to give the i3 8 more miles of range?
Can you stack up two or three batteries and convert the single-phase battery into a 208V three-phase battery unit, with a larger amp output?
Its' 2019 - current price of Goal zero 3kwh battery is over $3k - $1k per kwh
But current trading shows lithium ion wholesale at $0.14k per kWh this year. That is one overpriced battery pack.
(By comparison if 74kwh model 3 Tesla was priced at Goal zero level the battery itself would be almost twice what the car costs)
Thank you for making this video. Was very curious about this.
Matt Cohen ,. YES my dear Friend Matt ,.him make Great job,,
Remenber You are Welcome to Brazil.... Time for investiment here Now.

Thanks
I made a video on how to build one, check my video list on the channel page
Is it possible to drive and charge at the same time.
Change while driving?
No
I wonder. What if you put a step up transformer and used lower amp 220/240 charger.
it would take longer to charge
This makes me appreciate the Aptera equipped with solar panels - it will provide up to 40 miles per day extra driving.
As silly as this seems, if you're in some sort of situation where you need portable energy storage for driving around off-grid, I don't see any logical problem with using a small inverter generator.

Thanks for the test. Good to have an emergency back-up. How do you make a ground fault by-pass? I also liked the idea of a kw meter.
short ground and neutral in a plug. How advisable that is , upto you.
Is there a way to wire that battery to put out 240 volts? Wile it would put out the same ultimate power it should discharge much quicker.
This is a good experiment! You can add a solar panel so that you get more charge from the power station
Absence of anti wind fur cover ruined your video!
Dead cat, google it.

why don't they just make another set of battery bank that will charge other discharged battery bank for alternate charging and discharging?
Great video, thanks for testing this portable battery!
I see lots of people on youtube building home made free energy using dc motors with an ac converter and i wondering if a generator could be made strong enought to handle the tesler charge and i f the generator can be installed directly in the trunk or front hood of the care.
Good test. I predict all road side services (AAA and the like) will have these if they don't already. Juice you up and enable you to drive to a level 2 charging station or home, whichever is closer.
I wasn't wondering about increasing range; only if you could use it as an emergency if your battery died.
how long did it take for the battery to run out & is it possible to charge while driving?
The GoalZero Yeti 3000 is unavailable, what was the price? thank you
It’s also less dangerous to always carry along compared to a jerry can.
question if you could do direct DC to DC charge would it not charge faster
Any other optional products like GoalZero?
I drive a Kia Soul with only a 34 Kwh battery , I wonder if the 1400 yeti would work for me , Goal Zero needs to double their capacity and make it a little smaller , this could totally help if it was slightly better
i think the benefit would be for camping , and for photographers and how I use it ... I use a lighter adapter and recharge drone batteries and camera batteries , and then camping I use lights and power all sorts of stuff with my Electric car , like my electric car is a power generator .... but with a yeti would be worth it to have just to power all my gear and not use the cars energy to charge my gear and power my stuff and just save the range.
Audio is AWFUL. Maybe you should consider a wind generator/charger, judging by the wind noise?
4 thousands dollars for a battery pack will only charge your car about 10% that's horrible. definitely for emergencies only
My use case would be camping. If I had a solar panel and was camping and if I was there for a few days to charge up the electric car for the return trip
Did you write this music? It's really breaking some new ground.
LOL
Wouldn't carrying the extra weight of it drain the car battery aswell?

The i3 has Rex version. I was wondering if you have any issues on you i3.
Hi, great video. Can you please show us how you made the ground fault bypass? Cheers!
Still waiting for this reply!
Hi, thanks.
I saw your video on how to make the dummy. Cheers!
Can this yeti 3000 support charging and discharging at the same time?
YES! I have the Goal Zero Yeti 400 Lithium. It is designed to have solar panels (or wall / car inverter) plugged in at same time as you are drawing power from it. Display on Goal Zero constantly gives you a live update of draw vs input, expected depletion, or full time, wattage in / out etc.
This is a great idea/concept. I'd like to get a plug-in hybrid but the issue I have to get the costs down is that I can't charge the car using a wall charger due to the layout of our house and where our parking space is, so looking into portable battery charging or standalone solar power
Did you update the software to use the full gas tank?
Loved the video, but 'disliked' it purely on protest of double ads ruining it, and I'm commenting to show my support to your channel 👍🏼
Ian Graham you know UA-cam is in charge of that. not his channel.
The battery is smaller then the battery in the car, what do you think?
Quanto costa? E dove si puo ordinare?
why not make portable solar cell lightest for Telsa ? if long miles 5000.. battery portable is empty....
..also ...3 decent lead acid car batteries and an invertor would do same job at almost one tenth the cost of Goal zero
How much power do you use, carting this heavy battery around.......just in case you need 9 or 10 more miles at some point?
+Chris Darroch like I state in the video in the wrap up, it doesn't make sense unless you are simply using it to rescue an EV that has run out of juice. Like Have Someone Else bring it to you only in the occasion that you happened to be stuck somewhere.
You did imply at the end that it could be a drag on efficiency and that it certainly would if you were to drive "a ton of miles".......................This still implies that somebody might still actually choose, or have some option, to carry the battery in their car (not only for rescue situations). Seems that you didn't want to fully admit that the idea is a non starter, apart from rescue situations.
The Tesla Cybertruck and the Rivian R1S and R1T will come with regular electrical outlets. I think it would be fun to see if you could charge an EV...with another EV.
Thanks for the effort.you helped show me that it doesn't make sense to buy at this point in time. From what I see either go with the Tesla or a hybrid for those longer ranges.
During cold winter months, the battery pack might be better used on a portable electric heater.
I think it’s probably a better idea to remove weight from the car, get rid of the back seats, carpeting and anything else you can think of to get better range. Make it lighter.
How long did the battery last when connected to the i3?
Doesn't make sense for that tiny battery, but using a Solar Hybrid Inverter or Powerwall style unit would.
in india with a lot of power outages in smaller towns , many ppl have a inverter with battery at home.
Typically a 150 ah 220 v inverter battery setup costs 15000 Rupees, that's 185 usd.
the battery is 12 volts , 150 ah at 12 volts equals 1.8 kwh .
around 600 watts power rating.
So a 300 ah 800 w battery setup won't cost more than 40000 Rupees. That's 500 usd. Or use a pb acid battery , even cheaper. Every IC car has one...
I wonder if the Inergy Kodiak model could do a better job? Either way it kind of proves that this model is not reliable for RV users looking to ditch their gas generators.
What's the price difference between a jerrycan and this battery?
the price difference is something like $3000....
well done, great test! I made my own pack like this, 3.8Kwh 60 volt with a 3000w inverter.
Going Off Grid hi, can you post how to made your own 3kWh charger?
i have videos of it check them out
You use SAE (pounds) then call the trunk a boot. I'm confused by this.
LOL.... I've spent too much time on international forums apparently... lol
Wow, the future is about waiting around to drive an additional 10 miles. Absolutely brilliant.
XD Yeah, as stated, this is more just for an emergency situation / seeing what is possible. Not practical at all.
2021-04-14: Thanks! 3 1/2 years later, I’m guessing there are better back up units.
I’m adjusting to the possibility I could live long enough to be driving electric.
Using it as a charger is a waste because of inverter loss and cable resistance. If you could bypass the car battery and plug the Yeti into the car directly. Then you’d have something.
I agree that as a DIY solution this isn't practical. What I do wonder though is what if EV manufacturers made vehicles with bigger boot (trunk) space (and or fronk space) and made a battery pack to fit into that space. you saw with the Tesla that you could fit 2 x 3kwh batteries into the under-trunk space, and they were not even designed for it, a battery pack designed to fit there might well get 10kwh in. this would be especially useful for low budget EV's. Imagine an Ioniq with the ability to increase the battery from 28kwh to 38kwh, the highway range goes from 200km (124 miles) to 260km (161 miles), (assuming efficiency loss of 16%ish). That could easily make the difference of being able to make the next charger or not on a road trip.
It’s interesting as an experiment but in terms of efficiency it raises the point that if you did run out of power it would cost you less and take less time to call out road side assistance and be towed to the nearest rapid charger AND charge your car. You could do all of that for a lot less than the price of your portable battery and in less time probably.
Awesome... was looking at doing this, one thought. How about throwing the GoalZero 200w solar package on the roof... would it continuously charge?. Like a mini mobile solar station thats like 5000 dollars haha
Noticed the Tesla HPWC with the adapter to J1772 to charge your I3.
Have you considered how much range will you lose lugging around an extra 60 pounds?
Quick Quote really 60 lbs. over a long period of time sure. But on a single trip almost nothing. This is for absolute emergencies.
How to build a ground bypass? Please.
Right here my friend: ua-cam.com/video/BM_HWRLcf88/v-deo.html
;-) I was thinking Weight carried around. What about portable Honda Generators?
Treble charging losses, charge car, charge pack then charge car from pack? Every lb added reduces efficiency
Nice video but you speak about power in kWh which is live speaking about speed in miles. We need accurate words in videos like this. Power in W, Energy consumption in kWh and Capacity (available energy) in Ah.
