The controller of electric vehicle is not universal. The working voltage is 36V/48V/60V, and the phase angle is 60 degrees/120 degrees, which is generally indicated on the label. If you want to repair the electric car, you should automatically identify the dual-mode voltage.

The controller of electric vehicle is the core control device used to control the start, operation, advance and retreat, speed, stop and other electronic equipment of electric vehicle. It is like the brain of an electric car and an important part of it.
