need some help for the designing of a motor car/ bike
selection of motor , battery , etc...

 

Based on absolutely zero specifications or goals?

 

Buy one, take it apart and study.

And design one.

 

See if you can find a totaled nissan leaf to autopsy the inverter and motor from, to get an idea on how its done.

Though expect this thread to be closed shortly due to the TOS violation "Automotive Modifications"

 

I will only charge you 75% my normal rate since I pity you.

 

This will be closed due to the TOS, but you might want to go and join DIY electric car forum. http://www.diyelectriccar.com/forums/

U call tht pity ?

 

just remember, the leaf is automotive, so it dosnt have to conform to normal electrical safety standards. such as fuses large enough to let the wireing burn before blowing.

That's unlikely. I'm sure that Nissan doesn't want the Leaf to start a fire if a circuit gets overloaded, so I'm certain all circuits are well protected for that.

 

Automotive electrics actually have to conform to much higher safety standards than household electrics.

 

you mean like ford did swhen they had all those fires because a switch grounded? an input to the computer with enough current it could burn the wire, without fusing? the NEC does not cover automotive wireing.
