An Oil Electric Hybrid Sedan is a special type of bicycle that uses a battery as an auxiliary power source, has two wheels, and can be ridden manually, electrically, or with electric assistance.
1. Charger: This device replenishes the battery's power, generally using two-stage or three-stage charging methods.
2. Battery: Primarily lead-acid batteries, but nickel-metal hydride and lithium-ion batteries are also being used in some lightweight folding Electric Car.
3. Controller: This component controls the motor's speed and is the core of the Electric Car electrical system, providing undervoltage, current limiting, and overcurrent protection.
4. Motor: The motor converts the battery's electrical energy into mechanical energy, driving the Electric Car wheels to rotate.
Common types of motors used in Electric Car include: brushed toothed motors, brushed toothless motors, brushless toothless motors, brushless toothed motors, and side-mounted motors.
