> Are you planning on putting the batteries where the gas tank was? Will they fit?

No, batteries are larger. People tend to use the trunks for batteries, or convert pickups and put them in the beds.

> Will this have an adverse impact on vehicle dynamics?

It can, which most people deal with by placing the batteries carefully to maintain the same balance as before.

> How are you going to manage charging these things?

Most people put the charging plug where the gas cap was.

> What happens if the battery pack ruptures? Is safety even a concern?

Same as if your engine explodes. Safety is a concern in any car. Problems can happen in any car. Most DIY EVs put a cutoff switch, or even a main line you can literally cut right next to the driver as a final safety net in case of extreme emergencies. Better to kill the car than a person.

Does the fuel gauge show battery life or is it now useless?

Most people replace the gauges with new ones more applicable to the new information they'll need.

I know you had other questions, but it has been 10 years since I dabbling this space, and I don't remember every detail. But yes, there absolutely are new problems to solve. And people have been solving them for 20+ years now. There are books written on it, so if you truly want to know the answers, go read some of the books. Most of your questions either have easy answers, or are just a matter of making a choice between a few options.

The hard part is not putting together a working EV system. Most people's hardest task was mounting the motor to their transmission, because it often meant a custom designed, and custom machined mounting plate.

So again, you are correct that it is more than an engine swap, but not to the scale you are describing.




Funny how many folks wondering where to put the batteries, trunk seems so obvious after you hear it :)

Seems like this product is trying to solve that problem. Sounds like a big upgrade from what is currently available to people interested in these type of projects.


except of course most trunks have load limits which batteries can quickly exceed.

I find it disappointing how quick they are to dismiss issues with ruptured batteries by falling back on "well gas explodes" not acknowledging the issue of environmental and personal danger batteries create that require special handling

sure you can cram batteries here and there but the reason for the skate board layout companies have adopted that is to have management of weight, ease of manufacturing, sufficient space for range needs, and more.


I was only dismissing the questions because the person asking the question was dismissing the entire concept of electric conversions, apparently unaware that they have been done successfully for many years. Besides, ruptured batteries aren't the biggest safety concern. Getting in an accident and having a giant battery fly into the back of your head is a much bigger concern. And most of the concerns are still going to come down to the same solution -- secure them well, maintain them well, and be aware of all the repercussions of their placement.


So "gas explodes" doesn't carry its own environmental issue and personal danger too ?


Gasoline has a whole host of issues, but as far as I know there have been zero recorded cases of a modern gasoline tank spontaneously exploding while the car is sitting undisturbed in a parking lot. The advantages gasoline has here is that it ultimately requires tons of oxygen with a consistent fuel-air mixture in order to combust reliably. Burning gasoline in the open is not nearly as energetic as the process which occurs in a gasoline engine under ideal operating conditions (which are controlled meticulously by a computer for most cars), so even in an accident which results in a fuel leak+fire, you usually have a bit of time to get away from the car before it turns into a complete inferno. Obviously, there are exceptions to this, but it seems to be in a majority of cases the driver/passengers can get out in time.

Battery packs do not have the same 'problem'. They have all aspects of their chemical energy available nearly immediately, and can go from zero to 'you are dead' in just a matter of seconds.


Yes, it sounds like a great upgrade. I may big deeper into this once it really is on the market, and do some more conversions if it comes through as described.


Depending on the car, that might not be a good idea as far as weight balance goes. I'm working on an RX-8 conversion, and the advice I got from a mechanic that works on Mazdas is not to put too much weight in the back, because it would make it much harder to recover from a skid.


That would make it easier to recover. More weight = more traction.


> Most people's hardest task was mounting the motor to their transmission, because it often meant a custom designed, and custom machined mounting plate.

Canadian Electric Vehicles makes transmission adapters for a surprisingly large number of vehicles [1]. They come with adapters to attach a typical electric motor (1 1/8" keyed shaft) to the stock flywheel. So, that part at least is easy for quite a few cars (though could probably be done cheaper by someone with the right tools).

You're still pretty much on your own when it comes to mounting the motor/transmission to the car frame, but that's generally an easier problem that doesn't require as much precision.
