The Basic Structure and Function of Electric Bike

It is a special bicycle with two wheels, which can ride by human, electric or electric auxiliary function.

Charger, it is the battery to recharge the device, generally divided into two-stage and three-stage charging mode. Batteries, mainly lead-acid batteries, nickel-hydrogen batteries and lithium-ion batteries in some light folding electric vehicles began to use.

Controller, which is the electric bike kit of motor speed control and the core of electric bike power system, has the functions of under voltage, current limiting and overcurrent protection.

The switch, the brake, the power sensor, these parts are the signal input components of the controller. The switch signal is a control signal for the speed of an electric vehicle. When the brake handle signal is an electric signal of the electric vehicle brake, the internal electronic circuit is output to the controller by the gate.

When the controller receives this signal, it will cut off the power supply to the motor and realize the function of braking power failure. The power sensor is a device for detecting the speed signal of the pedal torque type when the electric vehicle is in the power state.

According to the signal size of the power sensor, the controller allocates different electric driving power to the motor, so as to achieve the automatic matching of human and electric power, and jointly drive the rotation of electric vehicle.
