MAIN COMPONENTS
On-Board Charger (OBC) : A device •
that charges the high voltage battery
by converting AC power from a domes-
tic supply into DC power and supplying
it to the battery.
Inverter : A device that transforms di- •
rect current (DC) from the high voltage
battery into alternating current (AC) to
power the electric motor. It also con-
verts braking energy into electrical en-
ergy and charges the high voltage
battery while decelerating or braking.
DC-DC Converter : A device that con- •
verts HV DC power from the HV bat-
tery to LV DC power which is required
to maintain LV battery charge, which in
turn powers the LV systems like lights,
wipers, infotainment, etc. in the vehi-
cle.
Electric Motor : A device that converts •
electrical energy into rotational me-
chanical energy which is then trans-
ferred as rotational torque to the
wheels through the gearbox.
High Voltage Battery (lithium ion •
polymer) - An on board high voltage
electrical energy storage device.
Power Distribution Unit : Distributes •
power from the high voltage battery to
the HV components like inverter, DC-
DC converter, E-compressor etc.
GENERAL WARNINGS
Your vehicle contains a sealed Li-ion •
high voltage battery. If the Li-ion bat-
tery is disposed of improperly, there is
a risk of severe burns and electrical
shock that may result in serious injury
or death and there is also a risk of en-
vironmental damage.
The EV system uses high voltage DC •
current. The system can be hot during
and after starting and when the vehicle
is shut off. Be careful of both the high
voltage and the high temperature.
Avoid being exposed to high-voltage •
components in the first place. Observe
all high-voltage warning labels these
indicate high-voltage components or
areas. Observe all orange cables and
other high voltage components, large
and small these carry high voltage.
Do not touch high-voltage components •
while the vehicle is in operation or
cranked state.
Do not disassemble, remove or re- •
place high-voltage parts and cables as
well as their connectors because they
