Chapter 3: Components of Electric Vehicles
Abstract: Electric vehicles (EVs) primarily use a battery pack , an electric motor , a power inverter , a DC-DC converter , an onboard charger , a charge port , and a power electronics controller , which work together to store energy, convert it, and power the wheels, replacing the traditional engine, fuel tank, and exhaust system . Key functions involve the battery storing DC power, the inverter changing it to AC for the motor, and the controller managing flow, while the charger handles external AC input . Core Components Traction Battery Pack : The main energy storage, typically lithium-ion, providing DC power. Electric Traction Motor : Converts electrical energy into mechanical energy to drive the wheels, offering instant torque. Power Electronics Controller (PEC): Manages the flow of electrical energy between the battery, motor, and other systems, controlling motor speed and torque. Inverter :...
