Overview of electric vehicle
Unlike a vehicle with an internal com
-
bustion vehicle electric vehicles are pro
-
pelled by an electric motor powered by a
high-voltage battery. When decelerating
or driving downhill, regenerative braking
can charge the high voltage battery. This
reduces energy loss and can increase
the distance to empty. When the battery
charge is not sufficient, AC charge (L2-
Normal), DC charge and Trickle charge
(L1-Trickle) are available. (Refer to
"Charge types for electric vehicle" on
page 1-16.)
What Does Regenerative Braking Do?
It uses the electric motor when deceler
-
ating and braking and recaptures &
transforms kinetic to electrical energy in
order to charge the high voltage battery.
(Torque is applied in the opposite direc
-
tion when decelerating to generate brak
-
ing force and electric energy.)
Battery information
The vehicle is composed of a high volt
-
age battery that drives the motor, air
conditioner, and charges an auxiliary
battery (12V) that drives all other 12V
systems.
The auxiliary battery is automatically
charged when the vehicle is in the
READY
mode or the high voltage bat
-
tery is being charged.
Main components of electric

tery.
僅
Inverter
: Transforms direct current
into alternating current to supply
power to the motor, and transforms
alternating current into direct current
to charge the high voltage battery.
僅
LDC
: Transforms (converts) power
from the high voltage battery to low
voltage (12V) to supply power to the
vehicle (DC-DC).
僅
VCU
: Functions as a supervisory con

troller of electric vehicle
僅
Motor
: Uses electrical energy stored
inside the high voltage battery to
drive the vehicle (functions like an
engine in a standard vehicle).
僅
Reduction gear
: Delivers rotational
force of the motor to the tires at
appropriate speeds and torque.
僅
High voltage battery (lithium-ion)
:
Stores and supplies power necessary
for the electric vehicle to operate (12V
auxiliary battery provides power to
the vehicle features such as lights and
wipers).
* OBC: On-Board Charger
* LDC: Low Voltage DC-DC Converter
* VCU: Vehicle Control Unit
僅 Do not remove or disassemble high
voltage components and high voltage
battery connectors and/or wiring
(orange cabling). Also, be careful not
to damage high voltage components
and the high voltage battery. It may
cause serious injury and significantly
