Analyze the composition of lithium battery electric bicycles

Lithium battery electric bicycle composition 1. Charger Charger is a device to make up the battery power, generally divided into two forms of charging two stages and charging three stages. Two-stage charging form: The first is constant voltage charging. The charging current gradually decreases with the increase of battery voltage. To a certain extent, the battery charger's voltage will rise to the set value in the future, and then it will Switch to charging. Three-stage charging mode: At the beginning of charging, the battery is charged at a constant current to quickly replenish energy; when the battery voltage rises, it is changed to constant voltage charging. At this time, the battery energy slowly compensates, and the battery voltage continues to rise. When the charging stop voltage of the charger is reached, it switches to trickle charging to maintain the battery and supply the battery's self-discharge current. 2. Batteries are used to power electric vehicles, and lithium batteries are the latest lithium batteries used in electric vehicles. Tips for use: The driver's main control board is the main circuit of the electric vehicle, which has a large working current and large heat. Therefore, electric vehicles should not be parked in the sun and should not stay in the rain for too long to prevent problems with the controller. 3. Controller The controller is a component that controls the speed of the motor, and is also the core of the electric vehicle's electrical system. The intelligent controller also has a variety of riding styles and self-checking functions of on-board electrical components. The manipulator is the core component of electric vehicle energy processing and various control signal processing. 4. Rotating handles and brake handles Rotating handles, brake handles, etc. are the signal input parts of the manipulator. The rotor signal is the driving signal for the rotation of the motor. The brake signal is an electrical signal output from the brake to the internal electronic circuit of the manipulator when the electric vehicle is braking. After the controller receives this signal, it will cut off the power of the motor to realize the brake power-off function. 5. Power sensor The power sensor is a device that detects the pedal speed signal of an electric vehicle during driving. The controller drives the electric vehicle to rotate according to the electric driving power to achieve the active matching of human and electric power. 6. The most important part of a sports electric bicycle is the engine. The engine of an electric bicycle determines the performance and grade of the car. At present, the motors used in electric bicycles are mostly high-efficiency rare earth permanent magnet motors, which are mainly divided into three types: high-speed brush + reduction motor, low-speed brush motor and low-speed brushless motor. Low-speed brush motors are relatively cheap, but their performance is poor; brushless motors require high quality controllers, and there are not many brands on the market. It is best for ordinary customers to choose this brand when buying. 7. Lighting and appearance lamps, the external part is a combination of parts that provide lighting and display the status of the electric vehicle. The appearance of the power supply generally includes battery voltage, vehicle speed, driving conditions, and light conditions. The smart appearance can also show the defect status of automotive electrical components. 8. Common structure Most electric bicycles use hub-type engines to directly drive the front or rear wheels to rotate. These hub-type engines, according to the output speed, do not cooperate with wheels of different diameters, and drive the vehicle at a speed of 20 km/h. Although these electric vehicles have different shapes and battery installation directions, their driving principles and working principles are the same. This electric bicycle is the mainstream of today's electric vehicle products. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
