Can the Dayang electric car still be driven after the wheels are submerged in water?

It depends on the duration of submersion and the depth of the water. Most pure electric vehicles are well-constructed and reasonably designed, with protective devices between circuits. Most importantly, they use lithium batteries. If the situation mentioned in the question occurs, the driver is unlikely to suffer significant harm. Waterproof rating: In the electrical system of electric vehicles, the "low-voltage system," which is the same as in traditional fuel-powered vehicles, does not have the capability to sustain prolonged water exposure. The waterproof rating is less than or equal to IPX5. If wires or the ECU are submerged in water for a period, water ingress may occur, leading to short circuits in the low-voltage circuit. Taking the ECU (vehicle computer) as an example, although a short circuit in the low-voltage system due to water ingress will not cause electric shock injuries, it can render the vehicle undrivable. IP67 standard: Current pure electric vehicles meet the IP67 standard, theoretically ensuring safety even when submerged in water. Since electric vehicles do not have an engine, there is no need to worry about water entering through the intake or exhaust pipes and damaging the engine. Therefore, electric vehicles actually have much better water-wading capabilities than internal combustion engine vehicles.
