Abstract
A power storage device has a plurality of series-connected storage battery units, battery circuits associated with the storage battery units to control or monitor the storage battery units, respectively; a main circuit of a potential level different from that of the battery circuits; and a potential level changing circuits connecting the battery circuit to the main circuit. The power storage unit is small in construction and operates at a low power consumption in a high control accuracy.
