1. Immediately disconnect the power supply: For safety reasons, the power switch of the electric vehicle should be turned off immediately to avoid short circuits or further damage to the circuit.
2. Check circuit connections: The vehicle's chirping after rain may be due to a short circuit or poor contact caused by rainwater seeping into the circuit system. Check for water stains or corrosion at the battery, controller, and wiring connections to ensure all connections are secure and dry.
3. Drying treatment: Use a hair dryer or natural air drying method to thoroughly dry the circuit part of the electric vehicle. Be particularly careful not to use hot air to avoid damaging electronic components. After drying, try starting the vehicle again and observe if there is still any buzzing phenomenon. If the problem persists, it is recommended to seek the help of professional maintenance personnel.
