What are the reasons why BAIC New Energy cannot charge?
2 Answers
The reasons why BAIC New Energy cannot charge are as follows: 1. The charger of the electric vehicle is damaged: The capacitor in the circuit may be damaged, or the wire connecting the charger to the battery may be broken, resulting in the charger's light being on but the battery not being charged. 2. The battery is damaged: The wire connecting the batteries in series inside the battery may be melted, or the power wire at the battery charging port may be melted. Use a multimeter to test whether the battery's resistance is infinite. If it is, it means a wire is melted. Open the battery box and reconnect the wire. 3. The battery pack is damaged: Open the battery box and measure the voltage and resistance of each battery in the pack one by one. Replace any abnormal ones. Alternatively, the battery may need to be awakened. Use a charger with a higher voltage than the charging voltage to charge and awaken the battery. 4. Low temperature conditions: When the temperature is too low, the electrolyte inside the battery may freeze, making it impossible to charge. Wait for the electrolyte to thaw before charging. Additionally, do not charge rashly in such conditions, and pay attention to battery maintenance in daily use.
My BAIC electric car couldn't charge properly recently, probably due to the charging gun not being plugged in tightly or poor socket contact. That night at the public charging station, after swiping the card to start, the lights didn't come on at all. I tried unplugging and replugging the gun head and noticed some wobbling, possibly due to a loose interface. After fiddling with it for a while without success, I went to the 4S shop the next day. They diagnosed it as a fault in the small circuit board inside the onboard charger. They also mentioned that sometimes in extremely cold winter weather, the battery might enter protection mode and refuse to charge. They suggested trying a different charging pile first in the future, as the issue might be external - after all, unstable voltage can easily cause the system to lock up.
