How to charge an electric car?

With the completion of the Shanghai-Chengdu high-speed charging station, it is possible for electric vehicles to run long distances. So how do you charge an electric car? The author sorted it out for everyone.　　 1. Regular charging. The electric vehicle battery should be charged immediately after the discharge is terminated (in special cases it should not exceed 24h), the charging current is quite low, the size is about 15A, this kind of charging is called regular charging (ordinary charging). Conventional electric vehicle battery charging methods all use small current constant voltage or constant current charging, and the general charging time is 5-8 hours, or even more than 10 to 20 hours.　　2, fast charging. Fast charging, also known as emergency charging, is to provide short-term charging services within 20 minutes to 2 hours of electric vehicle battery parking with a relatively large current for a short time. The general charging current is 150-400A. However, compared with the conventional charging mode, fast charging also has certain shortcomings: the charging efficiency of the charger is low, the corresponding work and installation costs are high, and the charging current is large, so special consideration is given.　　 3. Mechanical charging. That is, the battery pack quick replacement system. By directly replacing the battery pack of the electric vehicle battery to achieve the purpose of charging it. Due to the heavy weight of the battery pack, the professional requirements for battery replacement are relatively strong, and professionals must be equipped to quickly complete the battery replacement, charging and maintenance with the help of professional machinery.　　 The above are three ways to charge electric vehicles, I hope it will be helpful to everyone.
