What is the function of the controller of an Golf Cart?

The main electrical components of an Golf Cart are power batteries, electrical control systems, motor speed control systems, drive motors, transmission systems and drive wheels. The controller is the core controller used to start, run, advance, retreat, stop and other electronic devices of Lithium Golf Carts. If the battery is their heart, then the controller is their brain, which is equally important. What are the common faults of the controller?

1. The riding noise of Lithium Golf Carts is loud and the speed slows down with load. After the car stops, the car cannot be zero-started. It can only operate normally after the motor starts.

Diagnosis and maintenance: This is a symptom of motor phase loss. Most controllers are now intelligent, and zero-start will shake due to phase loss. This may be a "morbid" state caused by damage to the motor Hall. Another possibility is that there is a problem with a phase line circuit inside the controller. First carefully check whether there is a problem with the connection line. If the Hall and connection lines are detected normally, then there is a fault in the internal components of the controller. Please replace the controller!

2. The Golf Cart is not moving when it is powered on, and it is difficult to push it, and it makes a "thumping" sound when pushing it.

Diagnosis and repair: This is because the motor wire is short-circuited due to a virtual contact. You can unplug the three thick phase wires of the motor. If the difficulty in pushing the cart disappears, it means that the controller is broken. Please replace it. If it is still difficult to push, it is a problem with the motor, which may be caused by a short circuit in the motor coil.
