Lithium Battery Electric Bicycle
Lithium battery electric bicycle refers to an electric bicycle that uses lithium batteries as an auxiliary energy source. It is equipped with electromechanical integrated personal vehicles such as motors, controllers, batteries, steering handles and other control components and display instrument systems.
The main components
Charger
The charger is a device for replenishing the battery, and is generally divided into a two-stage charging mode and a three-stage mode. Two-stage charging mode: First, constant voltage charging, the charging current gradually decreases with the rise of the battery voltage. After the battery power is replenished to a certain extent, the battery voltage will rise to the set value of the charger, and at this time, it will be converted to trickle charging. Three-stage charging mode: When charging starts, the constant current is charged first, and the battery is quickly replenished; when the battery voltage rises, it is converted to constant voltage charging. At this time, the battery energy is slowly replenished, and the battery voltage continues to rise; the charging end voltage of the charger is reached. When the value is changed, it is switched to trickle charge to maintain the self-discharge current of the battery and the supply battery.
The battery is the on-board energy that provides the energy of the electric vehicle. The lithium battery electric vehicle uses the latest lithium-ion battery.
Usage Tip: The main control board of the controller is the main circuit of the electric vehicle, which has a large working current and will generate a large amount of heat. Therefore, do not park the electric vehicle in the sun, and do not expose it to rain for a long time to avoid malfunction of the controller.
Controller
The controller is the component that controls the speed of the motor and is the core of the electric system of the electric vehicle. It has undervoltage, current limiting or overcurrent protection. The intelligent controller also has a variety of riding modes and self-checking functions for vehicle electrical components. The controller is the core component of electric vehicle energy management and various control signal processing.
Motor
The most important accessory for an electric bicycle is the electric motor. The electric motor of an electric bicycle basically determines the performance and grade of the electric bicycle. Mainly divided into high-speed brush + gear reducer motor, low-speed brush motor and low-speed brushless motor, the current high-speed brush + gear reducer motor performance is best, the price is also expensive; low-speed brush motor is cheaper, but performance It is worse; brushless motors have very high quality requirements for controllers, and there are not many brands on the market. It is best for ordinary consumers to choose brands when purchasing.
