摘要
A coil is electrically connected to one of storage cells to charge it, and after that, the coil is electrically connected to the other one thereof to charge it. In a first charging period, a path of a charging current flowing into a reference voltage through the coil is formed, in a second charging period, a path of a charging current flowing into a second cell from the coil is formed, in a third charging period, a path of a charging current flowing into the reference voltage through the coil is formed, and in a forth charging period, one end of the coil is electrically conducted with one end of the first cell and another end of the coil is electrically conducted with another end of the first cell to form a path of a charging current flowing into the first cell from the coil.
