The controller can realize the direct short-circuit protection of the output terminal, even when the motor is at the highest speed action (the highest voltage is usually output at this time) directly short-circuit the output terminal of the controller, the controller can also be very reliable protection. During protection, the circuit automatically reduces the output current to protect the safety of the battery.
The controller adopts a double closed loop control system (brushless: speed/current double closed loop, brush: voltage/current double closed loop). Due to the existence of the current loop, the current can be limited, which can protect the electric vehicle in various normal conditions.
The control system of an electric vehicle motor is generally composed of a motor, a power converter, a sensor and an electric vehicle controller.
Electric bicycles have many inconspicuous, but very important small parts and electric bicycle controllers are one of them. Don't look at the controller inconspicuously, but your electric bicycle can be started, advanced, retreated, and stopped. So what are the reasons that can cause the failure of the electric vehicle controller?
