Club Car Controllers and Troubleshooting

The  Club Car controller measures the batteries’ current and voltage to adjust the golf cart's speed. It monitors the state of the motor and generates a signal to match the alternating currents. The Club Car controller is also known as a speed controller, and the best thing about the controller is that it works as a brain and speed control system for the golf cart.

Functions of Club Car Controller

As the name suggests, one of the important functions of a speed controller is to allow the controller to manage the vehicle's speed. The speed controller controls the acceleration and deceleration of a golf cart and allows the rider to adjust the motor's current. The controller plays an important role in managing the golf cart's power system.

Following are some of the primary functions of the speed controller:

  • Limiting Motor Current – Protects the motor and controller from damage in case of stalling and overloading.
  • Limiting Battery Current – Managing current drawn from the battery so that the battery could be protected from excessive discharging and damage.
  • Thermal Protection – Protects the speed controller from overheating in unfortunate conditions.
  • Acceleration Rate – The Rate of acceleration to determine how fast Club Car accelerates when full throttle is applied.
  • Feedback support for the device

Some speed controllers allow customized programming to change the basic functions, especially top speed. How customizable your controller will be is based on whether your electric Club Car golf cart is a Series system or a Shunt system.
