An electric car has fewer moving parts than an internal combustion engine car. It has one moving part, the motor, whereas the gasoline-powered vehicle has hundreds of moving parts. These are the critical components of the EV, namely: the battery, charge port, DC/DC converter, electric traction motor, onboard charger, power electronics controller, thermal system, traction battery pack, and the transmission.
Fewer moving parts in the electric vehicle leads to another important difference. The electric vehicle requires less periodic maintenance and is more reliable. The gasoline-powered vehicle requires a wide range of maintenance, from frequent oil changes, filter replacements, periodic tune ups, and exhaust system repairs, to the less frequent component replacement, such as the water pump, fuel pump, alternator, etc.
BATTERY
It gives electricity to power the entire vehicle by storing the electricity required to run your EV. The higher the kW of the battery, the higher the range.
CHARGE PORT
It allows the vehicle to connect to an external power supply and to charge your battery.
DC/DC CONVERTER
It converts higher-voltage DC power from the traction battery pack to the lower-voltage DC power which is necessary to run the vehicle and recharge the battery.
ELECTRIC TRACTION MOTOR
It runs your vehicle’s wheels by using the power from the electric car battery pack.
ONBOARD CHARGER
A device built into the vehicle that converts AC power from the charger into DC power and stores it in the battery. It also checks the battery characteristics such as temperature, current, and voltage.
POWER ELECTRONICS CONTROLLER
It monitors the flow of electrical energy from the electric car battery. It controls the electrical motor speed and the torque.
THERMAL SYSTEM (COOLING)
It manages a proper temperature range of the engine, power electronics, electric motor, and the other components.
TRACTION BATTERY PACK
It stores electricity for use by the electric traction motor.
TRANSMISSION
It delivers the mechanical power from the electric traction motor in order to run the wheels.
