POWER SUPPLY APPARATUS

摘要

This power supply apparatus includes an assembled battery (A) having a plurality of unit batteries (a) disposed on a same plane, and an assembled battery (B) having a plurality of unit batteries (b) disposed on a same plane. In the power supply apparatus, the electrodes of the assembled battery (A), and the electrodes of the assembled battery (B) are electrically connected to each other via a bus bar, and at least a part of the bus bar is disposed in a gap between the unit batteries (a) of the assembled battery (A). In this power supply apparatus having the assembled batteries connected therein, energy density of the power supply apparatus can be easily increased and the assembled batteries can be easily electrically connected to each other by reducing the capacity of an electrically connecting section of the assembled batteries.
