Pay attention to some key points when riding an electric car in rainy season and ride safely before going home.

Three Effects of Electric Vehicles in Rain

The immersion of electric vehicles has three effects. First, although the motor controller is waterproof, it is usually not very waterproof, which may directly cause the controller to burn out due to water ingress. Second, if the motor is flooded, the joint will be short-circuited, especially when the water level is deep; Thirdly, if water enters the battery box, it will directly lead to a short circuit between the positive and negative electrodes, a slight consequence will be damage to the battery, and the most serious consequence will directly lead to the battery burning or even explosion.

What should I do if the electric car is soaked in water during the rainstorm?

From a safety point of view, the battery and controller are key components. Due to improper use or heavy rain in the middle of riding, some car owners accidentally soak their electric cars in stagnant water, and continue to use them without paying attention to maintenance after the rain, which is prone to motor inversion and electric cars out of control.

Soak the battery in water to dry, and then charge it. Various brands of electric vehicles have taken many waterproof measures, such as controllers, batteries and motors, and the waterproof performance is still good. Therefore, it doesn't matter if the electric car gets wet by the rain, but this doesn't mean that the electric car can "walk" in the water at will. I would like to remind all car owners not to charge the electric car battery immediately after it is wet by rain. Be sure to put the car in a ventilated place to dry before charging.

The controller is prone to short circuit and out of control when water enters. The controller of the battery car is easy to cause the motor to reverse. After the electric vehicle is seriously flooded, the owner can remove the controller to dry the accumulated water inside, dry it with a hair dryer and then install it. Note that it is best to wrap the controller with plastic after installation to increase waterproof ability.

In addition, it should be noted that electric vehicles ride in the water, and the water resistance is large, which is easy to cause the balance to get out of control; It is very dangerous to ride on the stagnant water section to prevent the manhole cover from being pushed away by the current. Therefore, it is better to get off when encountering stagnant water.
