A power storage module includes a power storage component unit and a connector module. The power storage component unit includes power storage components including electric terminals positive terminals, negative terminals) on one side. The connector module is attached to the power storage component unit to electrically connect the power storage components. The connector module includes bus bars and a holder. The bus bars connect the electric terminals of the power storage components that are adjacent to each other. The holder holds the bus bars. The holder includes a bus bar holding surface that includes bus bar placing sections on which the bus bars are placed. The holder includes restricting receptacles and restricting tabs fitted to the bas bars placed on the bus bar placing sections to restrict removal of the bus bars from the holder and displacement of the bus bars from the bus bar placing sections.

An electrical junction box configured to be disposed between a power supply and a load includes a cooling case that has an opening, a circuit assembly that is disposed closing the opening of the cooling case, and a liquid coolant that is stored in the cooling case. The circuit assembly has a case-facing surface that faces the cooling case, and includes a plurality of busbars that are disposed on the case-facing surface and constitute a conductive path between the power supply and the load. The busbars are immersed in the liquid coolant R.

Electrical junction box

An overcurrent protection apparatus that is connectable to a battery control unit to protect the battery control unit from an overcurrent. The overcurrent protection apparatus includes a fuse member that is provided with a fuse and a fusible wire that is connected in series to the fuse. The fusible wire is made of a conductor that has a melting point lower than that of copper, and has a fusing current value that is higher than that of the fuse. The fuse member is connected in series to the battery control unit.
