What to Do When an Electric Vehicle Fails to Start After Getting Wet?

Do not charge the electric vehicle battery immediately after it gets wet from rain. Be sure to place the vehicle in a ventilated area to dry before charging. Remove the controller, wipe out any accumulated water inside, and use a hair dryer to dry it thoroughly before reinstalling. When riding an electric vehicle through water, the significant resistance from water can easily cause loss of balance. It is best to dismount and push the vehicle when encountering flooded sections.
I've seen many cases of electric vehicles getting water damage, including failures to start after rainy days or water exposure. The key is to avoid forcing a start to prevent component burnout. Water can seep into the battery, motor, or controller, causing short circuits or corrosion. The first step is to push the vehicle to a dry, ventilated area, immediately disconnect the power, remove the battery, and wipe it clean. Use a towel or dry cloth to absorb external moisture, then let the vehicle air dry naturally for at least one or two days—avoid using a heat gun to prevent driving moisture deeper inside. Check the battery compartment and wire connections for signs of damage, but don't attempt disassembly to avoid compromising seals. If submerged in deep water, the battery and electronic modules may already be damaged, requiring professional cleaning or replacement at a repair shop. Safety always comes first—repairs for such issues are not only expensive but also affect longevity. It's best to develop a habit of avoiding puddles and promptly checking for accumulated water under the vehicle after rain.
