TEST SYSTEMS FOR ELECTRIC VEHICLE AND HYBRID ELECTRIC VEHICLE

摘要

PURPOSE: A test system for an electric vehicle or hybrid electric vehicle is provided to charge or discharge a battery mounted on the electric vehicle or hybrid electric vehicle and test a motor using one system. CONSTITUTION: A dynamometer(2) is connected to an output shaft(201) of a motor mounted on an electric vehicle or hybrid electric vehicle. A power device(3) supplies power to the motor or dynamometer. A circuit for testing the motor supplies power from the power device to the dynamometer or motor. A circuit for charging or discharging a battery is connected to a battery(300) mounted on the electric vehicle or hybrid electric vehicle and supplies power from the power device to the battery or discharges power from the battery. A circuit switching device(4) switches the circuit for charging and discharging the battery and the circuit for testing the motor.
