What is the use of electric vehicle controller？ (1)

1. Automatic recognition of motor mode system: automatically identify the commutation angle, hall phase and motor output phase of electric vehicle motor. As long as the power line, handle line and brake line of the controller are not wrongly connected, the input and output mode of the motor can be automatically identified, which can save the trouble of brushless electric vehicle motor wiring and greatly reduce the use requirements of electric vehicle controller.

        2. Ultra quiet design technology: the unique current control algorithm can be applied to any brushless electric vehicle motor, and has a considerable control effect, which improves the universal adaptability of the electric vehicle controller, so that the electric vehicle motor and controller no longer need to match.

        3. Constant current control technology: the locked rotor current of electric vehicle controller is completely consistent with the dynamic running current, which ensures the battery life and improves the starting torque of electric vehicle motor.

4. Follow up ABS system: it has anti charging EABS braking function, and introduces automobile grade EABS anti lock technology to achieve the effect of quiet and soft EABS braking. No matter at any speed, it can ensure the comfort and stability of braking, and it will not appear the phenomenon that the original ABS can't brake at low speed. It will not damage the motor, and reduce the mechanical braking force and pressure, Reduce the brake noise, greatly increase the safety of vehicle braking; When braking, decelerating or sliding downhill, the energy generated by EABS is fed back to the battery, which has the effect of anti charging, so as to maintain the battery, prolong the battery life and increase the mileage. Users can adjust the braking depth of EABS according to their own riding habits.

        5. Motor lock system: in the alert state, the controller will automatically lock the motor when the alarm, the controller has almost no power consumption, no special requirements for the motor, and has no impact on the normal implementation of electric vehicles in case of battery undervoltage or other abnormal conditions.

        6. Self check function: it can be divided into dynamic self check and static self check. As long as the controller is in the power on state, it will automatically detect the relevant interface state, such as rotating handle, brake handle or other external switches. In case of failure, the controller will automatically implement protection to fully ensure the safety of riding. When the failure is eliminated, the protection state of the controller will automatically recover.
