The voltage of the electric vehicle battery is insufficient, and the following methods can be used for repair:
1. Timely charging: Ensure that the charger is in normal working condition, connect the charger to the battery for charging until the battery voltage returns to the normal range. The charging time can be slightly longer, about 8 to 10 hours, but make sure to use an original charger that matches the battery.
2. Check and replace the battery: If the battery has been used for a long time, its capacity and performance may decrease, and a new battery should be considered. At the same time, regularly check the appearance of the battery, observe whether there are bulges, leaks, and other phenomena, as well as whether the battery connection wires are loose or corroded. If any problems are found, they should be dealt with in a timely manner.
3. Check the electric vehicle circuit: Low battery voltage may sometimes be caused by circuit problems in the electric vehicle. The wiring of the battery box, charger, and other related parts should be checked for correctness and firmness. If there are loose or damaged parts, they should be repaired or replaced in a timely manner. At the same time, keep the battery contact points clean to avoid poor contact caused by dust or corrosion.
In daily use, attention should also be paid to avoiding excessive battery discharge, planning cycling trips reasonably, and maintaining good charging habits, all of which can help extend the battery's lifespan and maintain its normal voltage level.
