The difference between fast charge and slow charge, from the point of view of the charging method, one uses alternating current, one uses direct current, fast charge refers to the size of the amount of electricity that can be charged in every small time, which is fast charge, simple to understand, that is, can be filled with 80% of the capacity in half an hour?
Charge through high-power direct current, and the charging voltage is generally greater than the battery voltage, and slow charge means that the current through is small, generally full of 6 to 8 hours, with alternating current.
