1) What is a suitable inductive electric motor ?? Provided that the number of revolutions of the engine does not exceed 3000 rpm

2) What is the battery capacity required for the car to travel 80 km ??

Note A manual transmission will be used

Answer 1

1. I think the best motor which is suitable for your electric car is 72V 3-PHASE AC INDUCTION MOTOR

and its maximum power rating is 30 kW

and it will produce 3000 rpm

and maximum torque is 105 Nm at 2500 rpm

it can be reaches 80 km/hour.

it can capable for 800kg weight.

2. best battery specifications for this car is as follows

rating is 16kWh, 88cells, 4-cell modules, li-ion battery

109Wh/kg; 330v , the maximum travelling range is 128km for one charge

charging times; if we put 13 hours at 115 vac of 15 amps then it will be charged

or if we put 7 hours at 230 vac of 15 amps then it will be charged.

if we charge the battery once it can be travell for upto 120km.
