ELECTRIC POWER TRAIN SYSTEM
ELECTRIC POWER TRAIN SYSTEM : System Description
INFOID:0000000010120553
CONTROL OUTLINE
EV requires electric power for the operation of all its systems.
The power stored in the Li-ion battery is supplied as high-voltage direct current to the high-voltage system
while also being converted to 13-15 V by the DC/DC converter and supplied to the 12 V power system.
VCM judges the vehicle status from various information and performs various EV system controls in a compre-
hensive manner.
