Inv
erter: Transforms direct
current into alternating current to
supply power to the motor, and
transforms alternate current into
direct current to charge the high
voltage battery.
䳜 (2)
LD
C: Transforms power from
the high voltage battery to low
voltage (12 V) to supply power to
the vehicle (DC-DC).

U: Functions as a supervi
-
sory controller of electric vehicle
䳜 (3) Motor: Uses
electrical energy
stored inside the high voltage
battery to drive the vehicle (func
-
tions like an engine in a standard
vehicle).
䳜 (4) Re
duction gear: Delivers rota
