What are the functions of electric vehicle controllers

Self-check function: 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 related interface status, such as the lever, the brake lever or other external switches, etc., once a failure occurs, the control The controller automatically implements protection to fully ensure the safety of riding. When the fault is removed, the protection state of the controller will automatically restore.   Reverse charging function: When braking, decelerating or sliding downhill, the energy generated by EABS is fed back to the battery, which has the effect of reverse charging, thereby maintaining the battery, extending the battery life, and increasing the mileage. Locked-rotor protection function: Automatically determine whether the motor is in a completely locked state or in a running state or a motor short-circuit state during over-current. If it is in a running state during over-current, the controller will set the current limit value at a fixed value to maintain The driving capability of the whole vehicle; if the motor is in a purely locked-rotor state, the controller will control the current limit value below 10A after 2 seconds to protect the motor and battery and save energy; if the motor is in a short-circuit state, the controller will output The current is controlled below 2A to ensure the safety of the controller and battery.   Dynamic and static phase loss protection: When the motor is running, when any phase of the electric vehicle motor has a phase failure, the controller will protect it to avoid the burning of the motor, while protecting the electric vehicle battery and prolonging the battery life. Power tube dynamic protection function: When the controller is running dynamically, it monitors the working condition of the power tube in real time. Once the power tube is damaged, the controller will immediately implement protection to prevent the cart from damaging other power tubes due to chain reaction. A more laborious phenomenon.   Anti-runaway function: It solves the running-away phenomenon caused by the brushless electric vehicle controller due to the handlebar or line failure, and improves the safety of the system.   1+1 power-assisted function: The user can adjust the self-assisted or reverse power-assisted by himself, which realizes the supplementary power during the riding and makes the rider feel more relaxed.   Cruise function: automatic/manual cruise function integration, users can choose according to their needs, enter the cruise in 8 seconds, stable driving speed, no need for handle control.   Mode switching function: Users can switch between electric mode or assist mode.  Anti-theft alarm function: ultra-quiet design, introduction of automotive-grade remote anti-theft concept, higher anti-theft stability, lock the motor in the alarm state, the sound effect of the alarm horn is as high as 125dB, which has a strong deterrent. It also has a self-learning function, and the remote control distance is up to 150 meters without error.   Reversing function: The controller adds the reversing function. When the user is riding normally, the reversing function is invalid; when the user is parked, press the reversing function key to perform auxiliary reversing, and the maximum reversing speed does not exceed 10km/h. Remote control function: Adopt advanced remote control technology, up to 256 encryption algorithm, multi-level adjustable sensitivity, better encryption performance, and no re-code phenomenon, which greatly improves the stability of the system, and has a self-learning function, remote control The distance is up to 150 meters without error. Ultra-quiet design technology: the unique current control algorithm can be applied to any brushless electric tricycle motor, and has a considerable control effect, which improves the general adaptability of the electric vehicle controller, so that the electric vehicle motor and controller are no longer Need to match.   Constant current control technology: The stall current of the electric vehicle controller is exactly the same as the dynamic running current, which ensures the life of the battery and improves the starting torque of the electric vehicle motor. Automatic recognition of the motor mode system: Automatic recognition of the commutation angle, Hall phase and motor output phase of the electric vehicle motor. As long as the controller's power line, handlebar line and brake line are not connected incorrectly, the input and output of the motor can be automatically recognized Mode, can save the trouble of wiring the brushless electric vehicle motor, greatly reducing the use requirements of the electric vehicle controller. Follow-up ABS system: It has anti-charging/automotive EABS braking function, and introduces automotive-grade EABS anti-lock technology, which achieves the silent and soft effect of EABS braking. It guarantees the comfort and stability of braking at any speed. There will be the phenomenon that the original ABS cannot brake at low speeds, and it does not damage the motor at all, reduces the mechanical braking force and the pressure of the mechanical brake, reduces the braking noise, and greatly increases the safety of the vehicle braking; and brakes and decelerate Or when sliding downhill, the energy generated by EABS is fed back to the battery, which has the effect of reverse charging, thereby maintaining the battery, extending the battery life, and increasing the mileage. Users can adjust the EABS brake depth according to their riding habits. 
custom electric bicycles are among the best and the long known , which plays an essential part in automatic manufacturing.
