1. The reasons for this situation can be roughly divided into three points: poor contact, protector action, and controller change.

2, poor contact: tighten all the joints with a screwdriver to prevent the bumpy vibration of the electric car when walking loose the joint. Also see if the lead of the electric car is broken, and there is no possibility of breaking the road.

4, controller: Replace a new controller to try, change their own, before changing the controller model, to ensure that the same model.

Then you need to check if there's a problem with the charger, and see if there's a power outage
The sudden power failure of the electric vehicle is mainly due to the poor contact of the power supply line of the battery power supply. Electric vehicles in the process of driving due to vibration will lead to poor contact of the power supply line, then you can check the fuse and connector, the line can be connected
