Advantages of fast charge: 0.5h can be filled with 80% of the capacity of lithium-ion battery, more than 80%, in order to protect the battery safety, charging current becomes smaller, charging to 100% time 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.
Slow charging advantages: The charging current and power of slow charging are relatively small, which is better for battery life, and the low peak of electricity consumption is low charging cost.
Disadvantages: Charging time is too long, generally 5~8h.
