What happens if an electric car gets wet in the rain?

If an electric vehicle gets wet in the rain, it may cause a short circuit or damage to the electronic components on the vehicle. The relevant explanation is as follows: Introduction: An electric vehicle is a relatively common means of transportation. The main components of an electric vehicle include the frame, motor, battery, and controller. The controller is used to control the circuit. Without the controller, the electric vehicle would not be able to operate normally. Supplementary explanation: Electric vehicles can also be called electric-powered vehicles, which are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as the energy source, and through components such as the controller and motor, convert electrical energy into mechanical energy to control the speed of the vehicle by adjusting the current.

My electric car is pretty much fine in heavy rain, as the manufacturer has done a thorough waterproofing design. The battery pack is entirely encased in a metal shell, the charging port cover comes with a sealing ring, and waterproof strips are applied to all body seams. It can handle daily downpours and even small puddles—just look at how many electric cars are driving around in the rain. Once, I left my car parked outdoors all night during a heavy storm, and it started up without any issues the next day. Still, to be safe, it's best to avoid deep water. If the water level rises above the chassis for more than half an hour, moisture might seep into the high-voltage wiring harness connectors, triggering insulation warnings or system shutdowns, which would require calling a tow truck. After the rain stops, remember to check the charging port for any accumulated water and wipe it dry with a cloth for peace of mind.

Last month, I specifically researched the waterproofing of electric vehicles. Most models now have battery packs with an IP67 waterproof rating, meaning they can be submerged in one meter of water for half an hour without issues. However, in actual use, the real concern is rainwater seeping into the interior: clogged sunroof drainage holes can cause water to soak the carpets, and aged door seal strips can lead to water accumulation at the bottom of the doors. Once after rain, I noticed water stains under the driver's seat, and upon inspection, found water pooled at the air intake filter—cleaning it fixed the issue. But be cautious about the headlight area: while the light housing itself is waterproof, if the turn signal wiring harness connector ages and lets water in, it might trigger a short-circuit error code. After rainy days, it's advisable to pop the hood and briefly check the wiring connectors.

Electric vehicles are theoretically safe in the rain as they are designed with waterproofing in mind. Key components like the motor controller are sealed with special silicone, and no water seeped in during immersion tests. However, there are three practical considerations: First, the charging gun port must be dried after getting wet before plugging in, as water on metal contacts can cause arcing and burning. Second, avoid driving with windows open during heavy rain, as water entering the central control screen may cause malfunctions. Third, regularly clear leaves from the rain tray below the windshield wipers to prevent clogged drainage holes, which can lead to water backing up into the engine compartment. Last week, I helped a neighbor fix a leak caused by leaves blocking the drain, which oxidized the ABS module connector, costing over 800 yuan to replace the part. Try not to park under trees.
