AutoBeta(AutoBeta.net)07/26 Report--

Recently, a Mercedes-Benz car was flooded while wading through a bridge in Huaibei, Anhui Province. then the electric seat in the car short-circuited, and the back of the seat began to tilt backward and caught the legs of the female passenger in the back row, leaving the female passenger trapped for several hours. it wasn't until the fire broke down at the scene that the danger was saved.

Seeing this, it is estimated that many owners of electric vehicles are a little uneasy. After all, even ordinary cars have such a big problem of short circuit, so the whole bottom of the electric vehicle is full of batteries. If it is short-circuited in contact with water, it should not be electrocuted or burned to death. There are plenty of torrential rains in summer, and urban waterlogging is also commonplace. If you can't drive an electric car on a rainy day, why do I buy an electric car?

In fact, consumers can think of this problem, and manufacturers have already considered it at the beginning of the research and development of electric vehicles. In our country, electric vehicles always carry out waterproof tests on batteries, motors and other parts before production. According to the regulations of the State Administration of quality Inspection, batteries must be immersed in 3.5% sodium chloride solution for two hours at full charge, requiring that the batteries do not catch fire and explode. In addition, electric vehicle parts mostly use IP67-level waterproof design, can be immersed in 1 meter of water for 1 hour, waterproof performance can be rest assured.

On the contrary, electric vehicles are better at wading than traditional fuel-fueled cars. Because the traditional fuel vehicle needs a lot of air as the basis when the engine works, it needs to design the air inlet and exhaust port in the body, so for the fuel vehicle, the working environment of the engine is open. the water-wading performance of the fuel vehicle largely depends on the height of the intake and exhaust port. For the electric vehicle, because the motor does not need air to provide assistance, so the motor is completely closed, so there is no need to design the intake and exhaust port, and naturally it will not be restricted because of the height of the intake and exhaust port like the fuel vehicle.

Although the electric vehicle does not have the problem of leakage or water in the battery compartment in terms of technology, it is necessary to drive cautiously on rainy days when the stagnant water exceeds the road along the hub, especially in the complex water section, it is best not to try it easily. After all, you drive an electric car, not a submarine.
