Abstract
A rechargeable battery module including a plurality of battery cells connected in series, a charging transistor, a balancing circuit and a control chip. The charging transistor is operative to convey a charging current to charge the battery cells. Based on voltage levels of the battery cells, the control chip disables the charging transistor and controls the balancing circuit to perform a first stage battery balance process. After finishing the first stage battery balance process, the control chip enables the charging transistor to charge the battery cells again. After being switched to a constant voltage charging mode, the control chip controls the balancing circuit based on the voltage levels of the battery cells to perform a second stage battery balance process.
