What are the main functions of this Pedal Assist E-Bike Kit Controller?

The main functions of this Pedal Assist E-Bike Kit Controller can be summarized as follows:
Motor control: According to the input signal of the pedal sensor or the speed control handlebar, the speed and direction of the motor are controlled to realize the driving, acceleration, deceleration and parking of the electric bicycle. Support stepless speed regulation, the sensor can use Hall element or wire potentiometer, so that the speed can be adjusted at will according to the driver's wishes.
Battery management: The controller can manage the battery to ensure that the battery works within a safe range and prolong the battery life. Including battery undervoltage protection function, when the battery voltage drops to the limit value, the controller protects and cuts off the battery power supply to avoid over-discharge of the battery.
Protection function: When the current of the motor reaches the limit value, the controller protects and limits the maximum output current, but does not shut down the output to prevent the electric bicycle from suddenly reversing due to the overcurrent protection action when going uphill. Prevent the motor or battery voltage from exceeding the normal working range, causing damage or malfunctioning. In the case of power tube damage, the controller can shut down the output to prevent the electric bicycle from moving at full speed in the case of out-of-control.
Fault diagnosis and prompts: Three working status indicator lights are specially designed and added to the electric bicycle instrument. These indicator lights are not only for decoration or to provide additional information, but more importantly, they can reflect the operating status of the electric bicycle in real time. When the electric bicycle is about to face undervoltage, the pre-undervoltage indicator light will light up to remind the driver to charge in time to avoid safety hazards caused by sudden power outages. When the battery power really reaches the undervoltage state, the undervoltage indicator light will light up, and the electric bicycle will automatically reduce the speed or stop running to protect the battery from excessive discharge. In addition to the battery status prompt, the line fault indicator light is also a very important function. It can light up when the internal circuit of the electric bicycle is short-circuited, broken or other abnormal conditions occur, prompting the driver or maintenance personnel to check and troubleshoot in time to ensure the normal operation and safe use of the electric bicycle.
Intelligent features: Modern electric bicycle controllers can adjust the power according to voltage changes. When the battery voltage of the electric bicycle gradually decreases due to the increase in riding distance, the controller will automatically adjust the output power to ensure that the electric bicycle can still maintain a stable speed after the voltage is reduced. This intelligent adjustment not only improves the endurance of the electric bicycle, but also ensures driving comfort and safety.
Soft start function: prevents the driver from operating the speed control handlebar too violently, causing impact on the battery, motor and mechanical transmission device of the electric bicycle.
Speed ​​limit function: when the controller speed is adjusted to the maximum output, the speed of the electric bicycle should not exceed 20 kilometers per hour to ensure driving safety.
Through the above functions, this Pedal Assist E-Bike Kit Controller can provide users with a safer, more stable and comfortable riding experience.
