What is the use of electric vehicle controllers

The electric vehicle controller is the core control device used to control the start, run, advance and retreat, speed, stop of the electric vehicle motor and other electronic devices of the electric vehicle. It is like the brain of the electric vehicle and an important part of the electric vehicle. Electric vehicle controllers also have different performance and characteristics because of different models. So what is the use of an electric vehicle controller?

The main features of electric vehicle controller are as follows:

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 connected correctly, the motor input and output 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.

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 general adaptability of the electric vehicle controller and makes the electric vehicle motor and controller 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.

Follow-up ABS system: It has anti-charge 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. The original ABS can’t stop the brakes at low speeds, 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’s braking; and brakes, decelerates or decelerates When sliding on a slope, 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. The user can adjust the EABS brake depth according to their riding habits.

Motor lock system: In the alert state, the controller will automatically lock the motor when the alarm is alarmed. The controller has almost no power consumption and no special requirements for the motor. Under battery undervoltage or other abnormal conditions, it has no effect on the normal operation of electric vehicles.

Self-checking function: divided into dynamic self-checking and static self-checking. As long as the controller is in the power-on state, it will automatically detect the related interface status, such as the lever, brake lever or other external switches, etc., once a fault occurs, the 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 to achieve a reverse charging effect, 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 overcurrent. If it is in a running state during overcurrent, the controller sets the current limit value at a fixed value to maintain The drive capacity 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.

Anti-runaway function: 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 use of self-assisted or reverse-assisted power, which realizes the supplementary power during riding and makes the rider feel more relaxed.

Anti-theft alarm function: ultra-quiet design, introduction of automotive-grade remote anti-theft concept, higher anti-theft stability, the motor can be locked in the alarm state, the alarm horn sound effect 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 a reversing function. When the user is riding normally, the reversing function is invalid; when the user is parked, press the reversing function button to perform auxiliary reversing, and the maximum reversing speed does not exceed 10km/h.
