Electric Vehicles (EVs)
Battery electric vehicles (BEVs or
EVs) are driven using a battery and
an electric motor. While general vehi-
cles use an internal combustion
engine and gasoline as fuel, electric
vehicles use electrical energy that is
charged inside the high voltage bat-
tery. As a result, electric vehicles are
eco-friendly in that they do not
require fuel and do not emit exhaust
gases.
Characteristics of Electric
Vehicles (EVs)
1. EVs are using the electrical ener-gy that is charged inside the high
voltage battery. In terms of air pol-
lution and greenhouse gas emis-
sions, EVs are cleaner than con-
ventional vehicles.
2. A 150 kW electric drive motor mated to a reduction gearbox
comprises the vehicle drivetrain.
This electric-only powertrain sig-
nificantly reduces engine room
noise and vibration while driving.
3. When decelerating or driving downhill, regenerative braking is
utilized to charge the high voltage
battery. This helps to minimize
energy loss and increases vehicle
range.
4. When the state of charge (SOC) of the battery is low, the EV battery
can be recharged through several
different charging methods. Refer
to “Charging Information" later in
this section.
Information
What does regenerative braking do?
Regenerative braking uses the electric
motor when decelerating or braking
which converts vehicle motion (kinetic
energy) to electrical energy to charge
the high voltage battery.
Battery Information
The vehicle is composed of a highvoltage battery that drives the
motor and air-conditioner, and an
auxiliary battery (12 V) that drives
the lamps, wipers, and audio sys-
tem.
The auxiliary battery is automati- cally charged when the vehicle is in
the ready ( ) mode or the high
voltage battery is being charged.
