For EVs closely reliant on digital management programs, publicity to water can have an effect on totally different elements in another way:
- Battery: It’s the core part of EVs, and water coming into the battery module can lead to quick circuits, harm, and even fires.
- Motor: Water coming into the motor may cause corrosion or quick circuits, affecting the motor’s energy output.
- Digital Management Unit (ECU): The ECU is liable for managing the varied features of the EV, publicity to water can result in malfunctions or full failure.
- Wiring and Connections: Water publicity may cause quick circuits, connector oxidation, affecting the automobile’s electrical energy and sign transmission.

Thus, harm evaluation and dealing with strategies for flooding that impacts the cabin are fairly related, and could be based mostly on a six-level water harm evaluation scale.
