Some questions about Electric Vehicle

[TheOne]

Lol, what a bs! The hp indicated of an ICE, is the effective motive power of the motor.

Sure you can run a car with a smaller motor, and you can easily calculate what will be your max speed with it.
But then you could also take a smaller ICE. The problem then is, you will not have much accelleration force anymore, when already driving with some speed. If you can live with that, you can take a smaller engine.
But usually small electric cars, have a very leightweight design. And this car, was designed for an ICE. So it's not that lightweight as it could be. But anyway, you can convert anything, you just have to tell, how far do you wanna be able to drive with this thing, how fast you wanna be able to drive this thing, and how much accelleration force you actually still want to have to get there...The rest is simple math...

BS indeed, EV mass are higher on DIY car not the opposite, the batteries, 75lb * 24 = 1800lb in batteries. ITs twice as an ICE motor, EV motor is around 150lb.

Total mass for EV is greater!

One possibility I like is to convert the drive train of the Twin to be the drive
train of one of those compressed air driven cars. Then add a two wheel trailer
with the overunity power supply and a 120/240 volt inverter. The compressed
air cars have a built in air-compressor that can plug into a utility line. In this case
just plug it into it's trailer. For running around town, park the trailer and recharge
in the evening, for going long distances; take the trailer along and recharge
continuously or stop along the way depending on the power available from your
overunity supply. Lots fun and all free.

LOL, one would usually never use that much batteries on a EV, if you don't want to go in a very high price segment, like the Tesla cars...
What I meant is, that usually the electric cars, are constructed lightweight. Which means the chassis is made e.g. out of plastic compund materials, etc... To have as little total weight as possible. Sure the batteries and also the motor will have quite some weight, therefore it's even more important, that the rest of the car is as light as possible. This is the reason why usual EV  are just small cars for driving a little bit around in the city, but not as a replacement for a car one would go on the highway for high speed or some longer distances.
But if you take this car, for a replacement, you have the problem that already the chassis is very heavy, which is quite a problem for an electric car...

If we do a calculation about the 10KW Motor.

Just for example lets say the motor will run with 120Volt then we need 11 batterys.
10 for the drive and 1 for the system.Size:  B x H): 350 x 166 x 174 mm
Lets assume,we take Panasonic 12 Volt 65 Amps the weight each is 23 kilogram
That makes a total of 253 Kilos for the light version and the Batterys might fit under the backseat.
120V*65 Amps gives out about 7.8KW/h

Might be a good Car for the city

You are not living on the same planet as us. a lot of peoples using 20 batteries and more, some use pickup, some car etc... They are no limit of what you can do, the only limit is your imagination, which is something you seam to not have.

In case you did not understand, a am talking about DIY car, you can do it with any car you want, the limit is your imagination.

Instead of bullshitting try to be helpfull and stop to be an asshole.
