Abstract
A charging method with hysteresis includes the steps of: performing a pre-determination process to check whether the battery temperature of a battery cell is higher than or equal to a predetermined temperature; if the battery temperature is higher than or equal to the predetermined temperature, enabling a hysteresis mechanism; Upon the hysteresis mechanism, initially charging the battery cell with a small charging current; performing a first determination process to check whether the battery temperature decreases to a first threshold temperature; if the battery temperature decreases to the first threshold temperature, charging the battery cell with a large charging current; performing a second determination process to check whether the battery temperature increases to a second threshold temperature; and if the battery temperature increases to the second threshold temperature, charging the battery cell with the small charging current.
