Recently, rain has not stopped over most of the country, and urban waterlogging has increased the difficulty of vehicle care. As more and more people use electric vehicles, it is well worth understanding the harm caused by water entering the battery.

Water immersion affects an electric vehicle in three ways

First, although the motor controller adopts a waterproof design, its water resistance is usually not especially good, and water entering the controller may directly burn it out.

Second, if water enters the motor, the joints will short-circuit, especially when the water level is very deep.

Third, if water enters the battery box, it directly shorts the positive and negative poles: the mild consequence is a damaged battery, and the worst consequence is that the battery burns out or even explodes.

The above are the harms of water immersion to an electric vehicle. Please take care when riding in the rain and protect your vehicle.
