The scope of the Powertrain, Motor, VCU & Transmission Working Group is:
EDU with 2 speed or 3 speed gear box
Two key value for EV Consumers are 0-100 Kmh acceleration and battery range
EV models in the market at this moment are using one speed EDU, therefore in order to satisfy consumers now a day, you’ll have to increase motor power, which will also increase cost and weight, therefore will also need bigger battery capacity.
1-2% of operation time need Max. power
Only need 1/3 of power for max. speed driving ?
Advantage to apply multi speed gear box
Satisfy 0-100 Kmh acceleration expectation with smaller motor, power supply
Reduce weight and cost of motor and MCU
Lower energy consumption thus extend vehicle mileage with same battery package
