What Causes the Abnormal Noise When an Electric Vehicle Gets Water Inside?
1 Answers
Electric vehicles producing abnormal noise after getting water inside is because water ingress after rain causes short circuits or malfunctions in the controller or wiring. Electric vehicles are relatively vulnerable to water, and it's common to hear sounds from the horn, alarm, or internal water flow after rain. Below are detailed explanations about water ingress in electric vehicles: Electric Vehicle Circuit Drying Method: The simplest troubleshooting method is using the circuit drying technique. The circuitry of an electric vehicle is not complex, especially for components like alarms, which are mostly located in the front. Use a screwdriver to remove the shell, carefully inspect the circuits, wipe away any internal water accumulation, and use tools like a hairdryer to dry out the moisture. Then, place the electric vehicle in a well-ventilated, dry area for some time. Generally, this can resolve the issue. Precautions for Water Ingress in Electric Vehicles: Do not power on immediately; ensure it is completely dry before resuming operation. Electric vehicles have certain waterproof capabilities, and most can be used again after drying. If the noise persists after 24-48 hours of being stationary, you can then inspect the control wiring of the electric vehicle. The main areas where the controller gets water are at the wire connectors, and water accumulation in control plugs can lead to appliance malfunctions. Disconnect each plug to drain the water and dry them with a hairdryer. If drying doesn't help, the vehicle should be sent to a repair shop for inspection.
