If the electric vehicle battery is not powered, you can follow the following steps:
1. Check the battery status and connection: Check if the battery is fully charged, and if so, charge it promptly; If the battery is fully charged, further check if the battery connection is secure, if the battery connector is loose or corroded, and clean the connector as necessary to reconnect the battery. At the same time, pay attention to checking whether the battery is aging or damaged, and replace it if necessary.
2. Check the circuit and fuses: Check whether there are any signs of damage to the controller and wiring of the electric vehicle, whether the power switch and start button are working properly, and whether the fuse is blown. Once burnt marks or blown fuses are found in the circuit, direct contact should be avoided and professional personnel should be promptly hired to repair the circuit or replace the fuses.
3. Check the charger and charging interface: Confirm if the charger is intact, try using another charger for charging, and see if the problem can be solved. At the same time, check whether the charging interface of the electric vehicle is damaged or blocked by foreign objects, and clean the interface or replace the charger in a timely manner.
If none of the above steps can solve the problem, it is recommended to contact the electric vehicle manufacturer or a professional electric vehicle repair shop for more accurate diagnosis and repair of the fault.
