Electric Car Evolution… What You Need To Know.
Electric Car Evolution – An electric car is an automobile that is propelled by one or more electric motors, using energy stored in rechargeable batteries.
The primary difference between a hybrid car and an electric car is that the hybrid car derives some of its power from a conventional gasoline engine.
On the other hand, a true electric car gets all of its power from electrical sources, and thereby is a completely non-polluting zero-emission vehicle (ZEV).
All electric cars specifications include;
- Battery (all-electric auxiliary): In an electric drive vehicle, the auxiliary battery provides electricity to power vehicle accessories.
- Chargeport: The charge port allows the vehicle to connect to an external power supply in order to charge the traction battery pack.
- DC/DC converter: This device converts higher-voltage DC power from the traction battery pack to the lower-voltage DC power needed to run vehicle accessories and recharge the auxiliary battery.
- Electric traction motor: Using power from the traction battery pack, this motor drives the vehicle’s wheels. Some vehicles use motor generators that perform both the drive and regeneration functions.
- Onboard charger: Takes the incoming AC electricity supplied via the charge port and converts it to DC power for charging the traction battery. It monitors battery characteristics such as voltage, current, temperature, and state of charge while charging the pack.
- Power electronics controller: This unit manages the flow of electrical energy delivered by the traction battery, controlling the speed of the electric traction motor and the torque it produces.
- Thermal system (cooling): This system maintains a proper operating temperature range of the engine, electric motor, power electronics, and other components. Stores electricity for use by the electric traction motor.
- Transmission (electric): The transmission transfers mechanical power from the electric traction motor to drive the wheels.
