What should you do if water gets into the lithium-ion battery of an electric vehicle?
Looking around, many electric bicycles are parked outside without any cover. The owners feel that the outer shell provides protection and they can be carefree, but once rainwater seeps into the electric vehicle, it can damage the motor controller, the motor, and the lithium-ion battery.
Although motor controllers are designed to be waterproof, they are not typically very waterproof, and water ingress can directly burn out the controller. If water gets into the motor, the wiring will short-circuit. If the battery box is submerged, it can cause a short circuit between the positive and negative terminals, resulting in minor damage to the lithium-ion battery, or even severe damage or explosion of the electric vehicle's lithium-ion battery.
So what should be done after water treatment of lithium-ion batteries for electric vehicles?
First, let the battery dry completely before charging. All brands of electric vehicles employ waterproofing measures, so there's no need to worry if your GM electric car gets wet in the rain. However, this doesn't mean that electric cars can be driven through water at will. We remind all car owners that if your electric car's lithium-ion battery gets wet in the rain, never charge it immediately. After charging, be sure to park the car in a well-ventilated area to air it out, for the same reason as if your mobile phone got wet.
Secondly, the controller is prone to short circuits and loss of control. Water in the electric vehicle controller can easily cause the motor to reverse. If the electric vehicle has been submerged in water for a long time, you can remove the water from the controller, dry it with a hairdryer, and then reinstall it. After installation, it is best to wrap the controller with plastic film to improve its waterproof ability.
Because of the high resistance of water, electric vehicles are prone to losing balance and control when driving through water. If they encounter water on a flooded road, they may hit a manhole cover, with potentially disastrous consequences. Therefore, for safety reasons, it is best to get out of the vehicle and push it when encountering water.
In addition, try to avoid using electric vehicles and walking in the rain. When parked outdoors, it is best to cover them with a raincoat. When charging, cover the power strip with a plastic bag to prevent water from entering the power strip and causing electric shock.
