What are the reasons why a new energy vehicle cannot be charged slowly?

Reasons why a new energy vehicle cannot be charged slowly: 1. The fuse inside the battery is broken, in which case only the fuse inside the battery can be replaced; 2. Poor contact, including many aspects, such as poor contact between the fuse tube and the fuse seat, poor contact between the plug and the socket, poor contact between the charger and the power source, etc., which will affect the normal charging of the electric vehicle, resulting in the battery not being charged or not being fully charged; 3. Poor contact of the plug-in inside the battery: mainly due to problems with the connection between the positive and negative poles of the battery, you can try re-plugging or replacing the wire; 4. The battery has exceeded its service life: the normal battery life is about 5 years, but if there are often incorrect charging methods, it will cause the battery to fail prematurely, and the solution is to replace the battery.
Last time I went camping, I ran into the trouble of slow charging not working, and it took me a while to figure it out. The most likely issue is that the charging gun wasn't inserted properly—you need to hear a click for it to lock in place. Another possibility is that the cooling fan of the onboard charger was clogged with mud or sand, causing overheating and triggering the automatic power-off protection. Or, your home power socket might have poor grounding—new energy vehicles have high grounding requirements, so try testing the ground wire with a voltage tester. The battery temperature being too high or too low can also cause charging to stop; in summer, temperatures above 50°C or in winter, below freezing, won't work. If you forgot to turn off the scheduled charging function in the car's system, it might show a charging failure—check the charging settings on the central control screen. Lastly, the metal contacts in the charging port might be oxidized; just clean them with a cotton swab dipped in alcohol. If none of these fixes work, you'll probably need to visit a 4S shop to check the wiring.
