Fast charge for high-power DC charging, generally using a special non-vehicle DC charger for charging, benefits: 0.5h can be filled with 80% of the capacity of the battery. After more than 80%, in order to protect the safety of the battery, the charging current becomes smaller, and the time to charge to 100% will be longer.
Disadvantages: Due to the characteristics of high charging voltage and large current, it will cause certain damage to the battery and reduce the service life of the battery at the cost of reducing the number of battery charging and discharging cycles.
