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.
