Can anybody give me idea about working efficiency of EV motor and efficiency of brake regeneration ?

A little late seeing this post..but the efficiency of electric motors varies. I've seen as low as 85% (typically brushed DC) and as high as 96%. To add to that, the efficiency of any electric motor changes depending on a number of factors, like speed and load. Generally, though, I think it's in the low 90's.

Brake regeneration, I've heard, is limited so that it doesn't capture 100% of the energy that it could. It also varies greatly by manufacturer. Sorry I can't give more precise data here. I think in mixed driving, regen can improve range by 5 to 15% depending on the vehicle and conditions.
