Abstract

The invention provides a power source apparatus and a vehicle with the same, capable of furthermore miniaturizing an outer case of the power source apparatus. 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.

Description

technical field

[0001] The present invention mainly relates to a power supply device for large current used as a power supply for driving a motor of a vehicle such as a hybrid vehicle or an electric vehicle, and a vehicle equipped with the power supply device. Background technique

[0002] A motor vehicle such as an electric vehicle running with an electric motor or a hybrid vehicle running with both an electric motor and an engine is equipped with a power supply device in which a battery unit is accommodated in an exterior case. In this power supply device, a plurality of battery cells are connected in series to form a battery block having a high output voltage in order to obtain an output for driving the vehicle by using an electric motor. The battery block is accommodated in the exterior case, thereby protecting the battery unit from external impact, and achieving dustproof and waterproof. In addition, in order to properly control the above-mentioned battery cells, it is...
