Why is the battery light on the electric car always lit?

Generally, when the battery light on a vehicle is illuminated, it indicates a fault in the vehicle's charging system. Common fault points include: Fault Point 1: The generator may be internally damaged, resulting in insufficient power generation. Fault Point 2: The generator's belt pulley may be slipping, obstructing the power source of the generator and preventing it from functioning. Fault Point 3: There may be a fault in the generator's wiring, leading to insufficient power generation. Fault Point 4: The battery may be experiencing a power loss issue, unable to store electricity, which causes the battery light to illuminate. In this case, it is necessary to check the battery's health status. If the battery health is below 10%, the battery needs to be replaced.
I've seen the electric car lights staying on, and I've encountered this situation a few times. Usually, it's because the switch is stuck or has poor contact. A loose spring inside the switch or oxidized contacts can keep the lights powered on. Automatic sensor lights can also malfunction; if the ambient light sensor is covered with dust or aged, it may mistakenly think it's dark and keep the lights on, leading to rapid battery drain. Another common cause is relay sticking, where the control module fails to return to the off state after being powered. I suggest manually trying to switch it on and off a few times to see if it resets; if that doesn't work, check if the fuse is blown. Deal with it early, otherwise, the battery may drain, and the car might not start. By the way, regularly cleaning the headlight area to prevent foreign objects from entering can help avoid this issue.
