When a new energy vehicle is flooded, the first step is to clean the dirt inside and outside the vehicle. Cleaning the exterior is straightforward, but the interior requires professional assistance. Then, park the car in the sunlight, open the windows for ventilation, and dry it out. Use the onboard computer for self-diagnosis to check if all vehicle equipment is functioning properly. For the flooded chassis, a thorough inspection is necessary, and rust-proof spray should be applied if needed. There are three main reasons why electric vehicles may encounter issues when flooded: 1. Issues with the sealing of the motor and battery: If the battery sealing meets relevant standards, there is no need to worry about flooding. Modern electric vehicles typically use permanent magnet synchronous motors, which have undergone water immersion tests and can operate underwater as long as the motor sealing remains intact. 2. Damaged wiring harnesses: Problems with wiring harnesses in electric vehicles are not difficult to resolve. Ensuring proper sealing of the motor and battery means the vehicle can theoretically continue driving as long as the driver has oxygen supply. 3. Insufficient waterproofing standards: The battery pack of an electric vehicle consists of battery cells enclosed in a metal casing. The waterproof standard for the battery pack casing is IPX7, meaning it can be submerged underwater for over half an hour without water ingress.
