EV CONTROL SYSTEM [(E)]


id3040002000e1


Outline

•  The PCM controls the electric motor based on the user’s requested output calculated from the vehicle conditions, such as the high voltage battery, and the accelerator pedal depression amount. As a result, drive force according to the user’s request has been achieved.
•  The PCM controls charging using the method corresponding to the type of charging power supply. As a result, high voltage battery charging corresponding to normal charging and quick charging has been achieved.
