The electric vehicle controller is the core component and is the component that controls the rotation of the motor. The damage of the microelectronics of the electric vehicle controller may be small, mainly due to the damage of high power components such as power tubes and capacitors. Damage to the power tube, commonly known as squib, can cause the electric vehicle to be unable to drive, and the instrument power light will flash or not. Electric motor motors have resistance and are difficult to implement.

If the controller is damaged, a short circuit will occur, the electric vehicle will burn out, or it will trip open. Reasons for damage: overload, long-term overload climbing, overpressure, excessive current, poor heat dissipation at high temperatures. It may also be caused by wiring errors and high temperature aging of electronic components (especially capacitance).

It should be noted here that the battery is usually 1-2 months or even longer after being used from the factory to the battery. During the storage period, the battery spontaneously reacts due to self-discharge inside the battery, and consumes a part of the power. The capacity value, so before the initial use, it is best to carry out supplementary charging, so as to avoid the customer mistakenly believe that the capacity is insufficient.
