CONTROLLER ENGINEERING - Help in the Selection

This month, Electric Vehicles of America, Inc. continues our series on engineering by discussing the Controller. The controller is the brains of the operation; it controls the energy going to the motor and can protect the motor from damaging itself.

The Controller should be sized properly for the application (weight, speed, terrain, etc.) and the voltage utilized. Selecting an undersized controller (e.g. 72V for a truck conversion) will decrease performance and eventually damage components. Selecting an oversize controller for the application increases the cost and decreases the efficiency of overall operation.
