The charger is a device that adds electricity to the battery, generally divided into two-stage charging mode and three-stage mode two. Two-stage charging mode: first constant voltage charging, charging current with the rise of the battery voltage gradually reduced, and so on after the battery charge to a certain extent, the battery voltage will rise to the charger set value, this time converted to trickle charging.

Three-stage charging mode: Charging starts, the constant current charge, quickly recharge the battery, and so on after the battery voltage rises to a constant voltage charge, the battery energy is slowly replenished, the battery voltage continues to rise, to the charging termination voltage value of the charger, to trickle charge to maintain the battery and supply the battery's self-discharge current.


Battery is to provide energy for electric vehicles with the vehicle energy, electric vehicles mainly using lead-acid battery combination.

Ni-MH batteries and lithium-ion batteries have also been used in some lightweight folding electric vehicles. Use prompt: The controller main control board is the main circuit of the electric vehicle, has the large working current, will emit the larger heat.

Therefore, electric vehicles do not park in the sun exposure, also do not long rain, lest the controller malfunction.


The controller is the part that controls the speed of the motor and is also the core of the electric system of electric vehicle with undervoltage, current limit or overcurrent protection function. Intelligent controller also has a variety of cycling mode and vehicle electrical parts self-test function.

The controller is the core component of electric vehicle energy management and various control signal processing.

Turn the turn, brake the The switch, brake, etc. are the signal input components of the controller. The turn signal is the driving signal of electric vehicle motor rotation. The gate signal is when the electric vehicle brakes, the gate to the internal electronic circuit output to the controller of an electrical signal, the controller receives this signal, it will cut off the power supply to the motor, so as to achieve the brake power-off function.
