Does Long-Term Fast Charging Harm the Battery of New Energy Vehicles?
1 Answers
Long-term fast charging does harm the battery of new energy vehicles. The specific impacts of fast charging are as follows: Charging Speed: The charging current is large, ten times or even dozens of times that of conventional charging current, significantly saving charging time for vehicle owners. It takes 0.5 hours to charge 80% of the battery capacity. Beyond 80%, to protect battery safety, the charging current decreases, and the time to reach 100% will be longer. Battery Damage: The characteristics of high charging voltage and large current come at the cost of reducing the number of charge-discharge cycles of the battery. This causes certain damage to the battery, reduces its service life, and affects the actual driving range of the vehicle.
