Problems solved by technology

The bus bar of this structure may cause an increase in contact resistance over time due to reasons such as corrosion of the connection part of the stranded wire and the crimp terminal
Although this disadvantage can be prevented by crimping the crimping terminals to the stranded wires and soldering or brazing the crimped parts, this bus bar takes time and effort to manufacture and the cost of components becomes extremely high. high disadvantage

Abstract

The power source apparatus has battery units 2 connected in series or parallel with bus-bars 6. Each battery unit 2 is made up of a plurality of connected battery cells 1. Each bus-bar 6 is metal plate formed with mutually perpendicular upright planar region(s) 6x and lateral planar region(s) 6y connected between connecting terminals 6a at both ends. Lateral and up and down relative vibration between battery units 2 connected to the connecting terminals 6a is absorbed by the upright planar region(s) 6x and lateral planar region(s) 6y.

Description

technical field [0001] The present invention relates to a power supply device that increases output by connecting a plurality of battery blocks in series or in parallel via bus bars, and particularly relates to a power supply device that supplies power to a motor that drives a vehicle, or that uses natural energy such as solar cells or late-night power for charging A power supply device, or a power supply device such as a backup power supply that is most suitable for a power failure, and a vehicle equipped with the power supply device. Background technique [0002] At present, a power supply device in which output is increased by connecting a plurality of battery cells in series has been developed. (refer to patent document 1) [0003] like figure 1 As shown, in this power supply device, four sets of battery cells 102 are housed in an outer case 109 , and adjacent battery cells 102 are connected in series through bus bars 106 . In the battery unit 102 , a plurality of bat...
