Power source apparatus with electrical components disposed in the battery blocks

摘要

The power source apparatus is provided with battery blocks 50 made up of a plurality of battery cells 1 connected in battery stacks, and an outer case that holds the battery blocks 50. A block circuit board 60 to control the battery cells 1 that make up each battery stack and electrical components 63 connected to the block circuit board 60 or the battery stack are disposed in the end-planes of each battery stack. With this arrangement, electrical components are disposed in each battery block eliminating the need for a special purpose electrical component case and allowing outer case enlargement to be avoided.
