The cold wave is coming, and the biting cold and snow have arrived! Rainy and snowy weather is very unfriendly to friends riding electric vehicles. Riding in rainy and snowy days is a great test for electric vehicles, so you need to be extra careful. Once the electric vehicle is infiltrated by rain and snow, it will mainly affect the vehicle in these three aspects:
First, although the motor controller has its own waterproof design, it is not very waterproof in fact. The water inflow of the controller is easy to cause short circuit out of control. The water inflow of the controller of the electric vehicle is easy to cause the motor to reverse, which may directly cause the controller to burn out in serious cases.
Second, if the motor enters the water, the line joint will be short circuited, especially in the case of deep water level. If it is not dried in time, it is easy to cause leakage and fire.
Third, if the electric vehicle battery is flooded, it will directly lead to a short circuit between the positive and negative electrodes. The slight consequence is to damage the battery, and the most serious consequence is to directly burn the battery.

What if the battery of electric vehicle gets water in rainy and snowy days?
1、 The battery is flooded, dried and recharged
Electric vehicles are equipped with certain waterproof measures at the beginning of design, so it doesn't matter to be wet by ordinary rain at ordinary times, but this doesn't mean that electric vehicles can "walk through" in the water at will.
Xiaoxin reminds all car owners that the electric vehicle battery should not be charged immediately after it is wet by rain. The car must be put in a ventilated place and fully dried.
Before the power supply is connected, wipe the battery and connecting socket with a rag or paper towel, which can effectively prevent the occurrence of dangerous situations such as short circuit of power supply and burning of transmission and motor.
2、 The controller is flooded, which is easy to be short circuited and out of control
Once the controller of the electric vehicle is flooded, it is easy to cause the motor to reverse. After the electric vehicle is seriously soaked, the owner can remove the controller, wipe the accumulated water inside, dry it with a hair dryer, and then install it. After installation, it is best to wrap the controller with plastic to increase the waterproof capacity.
3、 Don't ride in the water by force
The resistance of ponding is very large, which is easy to cause out of control of balance. Riding in the ponding section is very dangerous in case of potholes or broken well covers. Therefore, in case of ponding, it's best to get off and implement it.
Finally, we need to pay great attention to charging electric vehicles in rainy and snowy days. Charging safety is not a child's play. Protecting ourselves is also protecting others.
