The role and interrelationship of the four major parts of electric mopedsAccumulatorThe functions and interrelationships of, motor, controller and charger. Function The battery is the power source and energy carrier of the electric vehicle, and is used to drive the motor. The motor converts the chemical energy of the battery into mechanical energy, which turns the wheels.The controller controls the output current and voltage of the battery to control the motorRotating speed, That is, the speed of the vehicle. The charger is an electrical appliance that charges the battery, converts alternating current into direct current and controls its current and voltage to charge into the battery for storage. Interrelationship The battery is the core component of the electric bicycle. It receives the electric energy from the charger, stores it and finally outputs the electric energy through the motor, and the output is controlled by the controller. The charger is a device that directly contacts the battery. The quality of the charger directly affects the electrical performance and service life of the battery, and it must be "matched". The controller controls the current and voltage output of the battery, and has an under-voltage protection function. The level of the "under-voltage protection point" affects the depth of electric discharge, therefore, it affects the mileage, and if it is too low, it will cause over-discharge and damage the battery. The impact of the efficiency of the motor requires the power supply current of the battery.
