Abstract

A battery pack includes a battery assembly having a plurality of battery cells, a busbar module that includes a plurality of conductors and an insulating member which holds the conductors, a battery control unit provided at an end portion of the battery assembly in an arrangement direction of the battery cells, and an extraction conductor that connects a total electrode terminal connected to the battery assembly to a main circuit terminal of the battery control unit. The extraction conductor has a water escape portion which is located below an imaginary line connecting the total electrode terminal to the main circuit terminal, and an upper end of the water escape portion is formed at a location that is lower than a lower end of the main circuit terminal.

Abstract

Provided is a bracket struc-ture of an electrical connection box (1), wherein one of the brackets (6) is installed on one of the wider-faced sides of a con-nection-box main body (2), and the other bracket (5) is installed on the other wider--faced side of the connection-box main body (2), and the other bracket (5) is also made to intermesh and latch-together with aforementioned one of the brackets (6), with a purpose of suppressing the electri-cal connection box from becoming loos-ened, due to vibrations and such of vehi-cles. One of the brackets (6) is made to slide-intermesh with the connection-box main body (2), in one direction towards the other wider-faced plane, and other bracket (5) is made to slide-intermesh with the connection-box main body (2), in the opposite direction towards aforementioned one of the wider-faced planes. A latch-to-gether section (20) of one of the brackets (6) is made to ride over and become en-gaged with a first engaging section (19) of the connection-box main body (2), in one direction, and a latch-together section (30) of the other bracket (5) is made to ride over and become engaged with a second engaging section (38) of the connection-box main body, in the opposite direction. A second latch-together section (36) of the other bracket (5) is made to ride over and become en-gaged with a second engaging section (22d) of aforementioned one of the brackets (6), in the opposite direction.
