What is the problem when an electric vehicle does not display the battery level?
3 Answers
The issue of an electric vehicle not displaying the battery level could be due to a damaged power switch, a blown fuse, poor contact in the battery connection wires, or the fuse not being activated. Below are the relevant explanations: 1. Damaged power switch: If the power switch has poor contact or is already damaged, the electric vehicle's dashboard cannot receive power normally. For this situation, a new power switch needs to be replaced. 2. Blown fuse: Under certain abnormal conditions, the electric vehicle's fuse may blow, preventing the dashboard from receiving power and thus not displaying. For this issue, replacing the fuse can resolve the fault. 3. Poor contact in battery connection wires: Poor contact in the connection wires can cause unstable battery power supply, leading to no display. For this problem, check if the connection wires are loose and reconnect them if necessary. 4. Fuse not activated: The new national standard requires that charging circuits and battery output terminals should be equipped with fuses or circuit breakers. Sometimes, the electric vehicle dashboard does not display because the fuse is not activated.
My electric car has been running for almost three years, and recently the battery level display suddenly disappeared. This is really frustrating. It could be a malfunction in the instrument panel, such as screen aging or internal wiring short circuits, especially since long-term vibration causes significant wear. Another possibility is that the battery sensor is dirty or has failed, as dust accumulation can lead to incorrect readings. Sometimes, the software acts up, and restarting the car's system might fix it. If that doesn’t work, it’s best to take it to a professional shop to check the battery module and fuses. Delaying repairs increases driving risks, and without the display, you won’t even know the charging status. I usually make sure to keep the car clean inside and out to avoid minor issues turning into major repairs.
I usually enjoy tinkering with electric vehicle systems. A common reason for the battery level not displaying is a software bug, such as a program crash causing the display to freeze. Try restarting the vehicle's computer or waiting for a system update. On the hardware side, a faulty battery management module can directly affect the readings, and a broken temperature sensor might also give false readings. Loose or oxidized connection wires are frequent issues, so check the plugs and wire connectors. Avoid disassembling it yourself, as you might damage more components. It's best to use diagnostic tools for troubleshooting to ensure safe driving without affecting the range.
