How Much Does Fast Charging Affect New Energy Vehicle Batteries?
1 Answers
Fast charging has a significant impact on new energy vehicle batteries. Rapid charging can reduce the battery's cycle life because the battery converts chemical energy into electrical energy, and charging is a reverse chemical reaction. Frequent fast charging can diminish the battery's ability to restore, thereby decreasing the number of charge cycles. The difference between 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 up to 80% of the battery's capacity in half an hour. Slow charging refers to AC charging, which typically takes 6 to 8 hours. The speed of electric vehicle charging is closely related to the charger's power, the battery's charging characteristics, and temperature. Portable charging: Portable charging refers to using the portable charging cable that comes with the vehicle to connect to a standard household socket for charging. This is a very convenient charging method, as it allows charging wherever a socket is available. Generally, standard household sockets have a voltage of 220V and a current of 10A, theoretically providing a power of 2.2kW. However, in practical use, the charging power is typically only around 1.5kW.
