Because the power is small, you can draw your gun directly without any danger. If the public standard charging pile is used, it is best to stop the charging procedure before pulling out the gun, otherwise it may cause some unnecessary troubles, such as jamming and settlement errors. Matters needing attention in charging new energy vehicles: 1. First of all, use cars and charging piles that meet national standards, and don't use third parties or charging piles without national production inspection licenses. Qualified connection mode (especially grounding protection) is also particularly important in safety; 2. Before charging, confirm whether the car is in good condition and whether the charging equipment is normal. After charging, before leaving the site, ensure that the voltage and current are within the normal range. If conditions permit, regularly check whether the charging state is normal; 3. Connect the charging cable directly to the wall socket as far as possible, and check whether the charging socket is in good condition to avoid charging when the connecting cable is damaged, corroded or rusted; 4. Try to avoid using drag boards. If you need to use a mop, don't put the mop and the charging interface directly on the ground to avoid getting wet by the rain and exposing the mop to the sun. 5. Avoid exposing the charging cable to sunlight and charge it at high power. Exposure and continuous heating will cause the charging cable to overheat and ignite the socket. 6. Try not to charge outdoors in thunderstorm and rainstorm weather. If you are charging outdoors, you need to consider whether the socket has a rain cover and whether there is an anti-leakage canopy.
