KIA Niro: Review of electric vehicle

An electric vehicle is driven using a battery and an electric motor. While general vehicles use an internal combustion engine and gasoline as fuel, electric vehicles use electrical energy that is charged & stored inside the high voltage battery.

As a result, electric vehicles are ecofriendly in that they do not require fuel and do not emit exhaust gases.

Characteristics of electric vehicles

It is driven using the electrical energy that is charged & stored inside the high voltage battery. This method prevents air pollution since fuel, like gasoline, is not required, negating the emission of exhaust gases.

A high performance electric motor is used in the vehicle as well. Compared to standard, internal combustion engine vehicles, engine noise and vibrations are much more minimal when driving.

When decelerating or driving downhill, regenerative braking is utilized to charge the high voltage battery. This minimizes energy loss and increases 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")

Battery information

The vehicle is composed of a high voltage battery that drives the motor, air conditioner, and charges an auxiliary battery (12 V) that drives all other 12 V systems.

The auxiliary battery is automatically charged when the vehicle is in READY mode or the high voltage battery is being charged.


What does regenerative braking do?

It uses the electric motor when decelerating and recaptures & transforms kinetic to electrical energy in order to charge the high voltage battery.


     Main components of electric vehicle

     High Voltage (HV) battery (lithium-ion polymer)

    On-Board Charger (OBC): Transforms (inverts) AC power charge power, to DC power, to charge the high voltage battery Inverter: Transforms direct current into alternating current to supply power to the motor, and transforms alternating

     High voltage battery warmer system

    The high voltage battery warmer system prevents reduction of battery output when battery temperature is low. If the charging connector is connected, the warmer system automatically operates according to the battery temperature. Charging time
