Abstract:
1. A remaining capacity equalizing device for equalizing the remaining capacities of a plurality of storage cells that are connected in series to form a battery pack, comprising: an inductance having one end thereof connected to a reference node between mutually adjacent storage cells in the battery pack; first and second switching elements having one end each thereof connected to the other end of the inductance; a first switching switch group able to connect the other end of the first switching element to a high-voltage-side node of each storage cell of the battery pack that is connected on the high-voltage side of the reference node; a second switching switch group able to connect the other end of the second switching element to a low-voltage-side node of each storage cell of the battery pack that is connected on the low-voltage side of the reference node; and a controlling portion for controlling the ON/OFF switching of the first and second switching elements and the first and second switching switch groups; wherein: the controlling portion:
