Abstract

Electric vehicle (EV) powertrain dynamics and steady state parameters can only be acquired in controlled test conditions, what is not possible to obtain experimentally in real road traffic. This paper presents a test bench designed for modelling purposes of small EVs such as ISRobotCar [2]. The EV powertrain was tested to acquire the motor power driver, motor, gearbox and tire efficiencies. The experimental study covers the particularly interesting feature of EVs that consists on the regenerative braking capability. Tire slippage is also addressed. As main result, two efficiency maps are provided for ISRobotCar in traction and regenerative braking modes, respectively.
