The National Highway Traffic Safety Administration (NHTSA) of the US advises that automobiles outfitted with lithium-ion battery packs, after being submerged in water, ought to be stored a minimum of 50 toes away from any buildings, automobiles, or flammable supplies. This precaution is essential for stopping brief circuits from inflicting fires. For EVs closely reliant on digital management techniques, publicity to water can have an effect on completely different parts otherwise:
- Battery: It’s the core part of EVs, and water coming into the battery module may end up in brief circuits, injury, and even fires.
- Motor: Water coming into the motor could cause corrosion or brief circuits, affecting the motor’s energy output.
- Digital Management Unit (ECU): The ECU is liable for managing the assorted capabilities of the EV, publicity to water can result in malfunctions or full failure.
- Wiring and Connections: Water publicity could cause brief circuits, connector oxidation, affecting the automobile’s electrical energy and sign transmission.
