If water enters the battery of the electric vehicle, the accumulated water inside must be drained first. Wipe the water dry and blow dry with a hair dryer to reduce water residue. Finally, let it dry naturally for 1-2 days before use. Do not rush to charge the battery after water ingress. Wait for it to dry thoroughly, otherwise it may easily cause a short circuit between the positive and negative poles of the battery. If the water ingress is severe, it is necessary to seek professional maintenance, especially for lithium batteries.
What are the effects of water ingress on electric vehicles
Impact 1: Although the electric vehicle controller is designed in a waterproof manner, its waterproof performance is usually not particularly good. Water ingress into the controller may directly cause the controller to burn out, making it impossible for the electric vehicle to continue riding.
Impact 2: When passing through waterlogged areas, especially those with deep water levels, the electric vehicle motor is likely to get water. If water gets in, it will cause a short circuit at the motor joint, making the motor unable to operate and causing the electric vehicle to not function properly.
Impact 3: If water enters the battery box of an electric vehicle, it will directly cause a short circuit between the positive and negative poles. The slightest consequence is damage to the electric vehicle battery, while the most serious consequence can directly cause the battery to burn or even explode.
Extended information: Method for determining whether electric vehicle batteries need to be replaced
1. Is the electric vehicle's range less than 10km
Under normal circumstances, the range of an electric vehicle is about 40-50km, and as the usage time increases, the range will also decrease. When the range of an electric vehicle drops below 10km, it can be basically determined that the battery of the electric vehicle has reached a scrapped state, and it is necessary to replace the battery.
2. Does the battery charge to the drum
Secondly, car owners need to check if there is any bulge in the battery. If there is a bulge in the battery, it is generally unable to be repaired and can only be resolved by scrapping and replacing the battery. The operation of checking whether the battery is bulging is to use a screwdriver to remove the battery and observe if there are any bulging areas on the battery.
3. Is the battery aging
Finally, check if the battery is aging. If the battery is aging, it will generally experience deformation or leakage. Users only need to observe the surface of the battery. If the battery experiences deformation or leakage, it indicates that the battery has aged. It is necessary to discard and replace the battery with a new one.
