Energy conversion and development requirements for 72V lithium battery electric motorcycle
Nov 27, 2018

The drive motor of the 72V lithium battery electric motorcycle provides electric energy, and its equipment converts the power of the power source into mechanical energy. In use, it is driven by a transmission device or directly drives the wheel and the working device. Today, the most widely used power source for electric vehicles is lead. Acid battery, but with the development of electric vehicle technology, lead-acid batteries are gradually replaced by other batteries because of lower specific energy, slower charging speed and shorter life. The application of new power sources is being developed, opening up broad prospects for the development of electric vehicles.

The 72V lithium battery electric motorcycle converts the power of the power source into mechanical energy during use. In use, the DC series motor is widely used in electric vehicles through transmissions or directly driving the wheels and working devices. This type of motor has "soft". The mechanical characteristics are very consistent with the driving characteristics of the car. However, due to the existence of reversing sparks, DC motors have lower specific power, lower efficiency, and large maintenance workload. With the development of motor technology and motor control technology, DC brushless motors (BCDM) and switched reluctance motors are bound to be gradually adopted. (SRM) and AC asynchronous motor replaced.

Speed control device for 72V lithium battery electric motorcycle

The motor speed control device of the 72V lithium battery electric motorcycle is set for the shifting and direction change of the electric vehicle, and its function is to control the voltage or current of the motor to complete the control of the driving torque and the rotation direction of the motor.http://www.greenescooter.com/
