Why does an electric car suddenly stop working in the rain?

The reason why an electric car suddenly stops working in the rain is that the controller power plug gets short-circuited due to water ingress or the controller speed limit plug gets short-circuited due to water ingress. Below is an introduction to related content: Service life: The battery temperature should be minimized as much as possible to ensure good heat dissipation and prevent charging immediately after exposure to intense sunlight. Exposure to sunlight will increase the battery temperature and enhance the activity of various active materials in the battery, affecting its service life. Low-temperature conditions: Conversely, under low-temperature conditions, the battery has poor charging acceptance and insufficient charging. In such cases, it is necessary to increase the charging voltage and extend the charging time, as well as take insulation and anti-freezing measures, which will help ensure sufficient charging and extend the battery's service life.
I've encountered several instances where my electric vehicle wouldn't start on rainy days. Once during extremely heavy rain, when I pressed the start button after getting in the car, there was no response, and the dashboard showed warning lights. I suspected that rainwater had seeped into the charging port or that the battery system had activated its anti-leakage protection, as electric vehicles are particularly sensitive to moisture. I tried disconnecting the charger, drying the interface with a dry cloth, waited a few minutes, and then it started. Later, at the 4S shop, the technician said it was due to oxidized connectors causing a short circuit, and replacing the sealing cover solved the problem. It's recommended to cover the charging port in advance during rain and avoid parking in low-lying areas to reduce the risk of water immersion. If the vehicle temporarily fails to start, don't force it; seek professional help as soon as possible to avoid more serious damage. Regular maintenance should include cleaning drainage holes to keep them dry.
