Problems solved by technology

Therefore, even in the case of performing maintenance work when the power supply circuit between the power supply equipment and the load is cut off by the power supply circuit disconnecting device, sufficient care must be taken so as not to touch the power supply equipment itself (two main electrode terminals), and maintenance workers heavy burden

Abstract

A power source circuit shut off apparatus shuts off a circuit of a battery assembly in which plural battery cells connected in series are arranged in parallel. The power source circuit shut off apparatus includes a housing, a pair of bus bars that is arranged in the housing and is connected to the adjacent battery cells respectively, a switch section that is adapted to conduct electrical connection or disconnection between the pair of bus bars, and a retaining member which is formed on the housing and is configured to be retained to a resin frame part of a side surface of the battery cell.

Description

technical field [0001] The present invention relates to a power circuit disconnecting device for cutting off a circuit of a power source installed in a vehicle such as an electric car or a hybrid car. Background technique [0002] Electric cars or hybrid cars are gradually increasing as environmentally friendly cars. A power supply device including a battery assembly obtained by stacking a plurality of batteries is mounted in such a vehicle (for example, see Patent Documents 1 to 4). [0003] Since the power supply equipment installed in such a vehicle as an electric car or a hybrid car can have a larger capacity than a power supply circuit of a gasoline engine vehicle, etc., when repairing and maintaining an electrical system, etc., a power circuit disconnecting device is used to cut off the A power supply circuit between a power supply device and a load is used to ensure work safety (for example, see Patent Document 5). [0004] reference list [0005] patent documents ...
