What are the precautions for charging new energy vehicles?

New energy vehicle batteries can be divided into two main categories: storage batteries and fuel cells. The charging time for each brand and model of electric vehicle varies, and it needs to be answered from two aspects: fast charging and slow charging. Fast charging and slow charging are relative concepts. Generally, fast charging refers to high-power DC charging, which can charge the battery to 80% capacity in half an hour. Slow charging refers to AC charging, which takes 6 to 8 hours to complete. The speed of electric vehicle charging is closely related to the power of the charger, battery charging characteristics, temperature, and other factors. With current battery technology, even fast charging takes 30 minutes to charge the battery to 80% capacity. After 80%, to protect battery safety, the charging current must be reduced, and the time to reach 100% will be longer. 1. First, use vehicles and charging piles that comply with national standards. Do not use third-party charging piles or those without national production and inspection certification marks. Proper wiring methods (especially grounding protection) are also crucial for safety. 2. Before charging, confirm that the vehicle is in good condition and the charging equipment is functioning properly. After charging begins, ensure that the voltage and current are within normal ranges before leaving the site. If possible, regularly check the charging status to ensure it is normal. 3. Try to connect the charging cable directly to the wall socket, and ensure the charging socket is in good condition. Avoid charging if the connection cable is damaged or the socket is corroded or rusted. 4. Avoid using extension cords whenever possible. If an extension cord must be used, do not place the extension cord and charging interface directly on the ground to prevent water ingress during heavy rain. Also, avoid exposing the extension cord to direct sunlight. 5. Avoid exposing the charging cable to direct sunlight and charging at high power, as prolonged exposure and heat can cause the charging cable to overheat and ignite the socket.
When it comes to charging my new energy vehicle, I pay special attention to three things: the environment, equipment, and the battery. It's best to charge in a dry and well-ventilated area, avoiding direct sunlight or charging in the rain to prevent water from entering the charging port and causing a short circuit. I insist on using the original manufacturer's charger—I wouldn't dare touch those off-brand charging cables. Charging time shouldn't be unlimited; I unplug it when it reaches around 80% at night to avoid leaving it fully charged overnight, which can affect battery lifespan. During high-speed fast charging, I limit it to half an hour to prevent overheating, while for slow charging, I use the home socket charger and have installed an overload protection switch. Before heading out, I check the charging station status via a mobile app and avoid places with unstable power grids based on user reviews. I always inspect the charging port for any foreign objects or deformations before and after each charge—this habit has helped me avoid three potential failures at highway service stations.
