What are the hazards of water immersion in electric vehicles?

Recently, most areas of the country have been raining continuously, and urban waterlogging has increased the difficulty of vehicle maintenance. Due to the increasing number of electric vehicle users, it is necessary to understand the hazards of battery water.　　Electric vehicle immersion in water has three effects.　　First, although the motor controller is a waterproof design, usually the water resistance is not particularly good, and it may directly cause the controller to burn out due to the water entering the controller.　　 Second, if water enters the motor, there will be a short circuit at the joint, especially when the water level is very deep.　　 Third, if water enters the battery box, it will directly cause the positive and negative poles to short circuit. The slightest consequence is to damage the battery, and the most serious consequence is to directly cause the battery to burn or even explode.　　 The above is the hazard of water immersion of electric vehicles. I hope everyone will pay attention to riding on rainy days and protect your car. Previous: What should I do if the electric car is flooded?
