h2 id="how-electric-cars-work">How Electric Cars WorkElectric Motor
Electric cars use an electric motor to move the vehicle. Unlike traditional cars, there is no internal combustion engine. The electric motor gets its power from a battery pack. This battery stores electrical energy.
When you press the accelerator, the car's controller sends electricity to the motor. The motor then converts this electrical energy into mechanical power. This process drives the wheels and propels the car forward.
Charging Process
Charging an electric car is different from filling up a gas tank. You can charge at home or at public charging stations. At home, you can use a regular wall outlet or an EVSE (Electric Vehicle Supply Equipment).
Using a standard wall outlet takes longer but is convenient for overnight charging. EVSE units provide faster charging times. Public charging stations often have higher power levels, reducing charge time significantly.
Energy Conversion
The conversion of electrical energy to mechanical power is key in electric cars. The battery supplies direct current (DC) electricity to the inverter. The inverter changes DC into alternating current (AC) for the electric motor.
The motor then uses this AC electricity to create motion. As a result, the wheels turn, and the car moves smoothly and quietly.
Regenerative Braking
Regenerative braking helps recharge the battery while driving. When you brake, the electric motor works in reverse. It acts as a generator, converting kinetic energy back into electrical energy.
This stored energy goes back into the battery pack, extending your driving range.
Battery Management System
A Battery Management System (BMS) ensures optimal performance of the battery pack. It monitors temperature, voltage, and state of charge for each cell within the battery.
Key Components of Electric Vehicles
Traction Battery Pack
