Abstract: Disclosed is a base plate structure for an electricity storage pack including an electricity storage module including a plurality of electricity storage elements, the base plate structure including: a unit base plate that has a shape having a plurality of sides in a plan view, and on which at least one electricity storage module is to be placed; and a wiring member that is to be connected to the electricity storage module. The unit base plate includes: a plurality of unit routing grooves configured to route the wiring member such that a routing direction of the wiring member can be changed; and a unit coupling portion that is formed on each of the sides, and that is configured to couple the unit base plate to another unit base plate.

Abstract: An electricity storage module unit that can improve installation work efficiency, and that can be used to build an electricity storage pack that is versatile in terms of installation. An electricity storage module unit is provided with an electricity storage module that includes a plurality of electricity storage elements, and the electricity storage module unit includes: a wiring member that is connected to the electricity storage module; a wiring connection part that connects the wiring member to the wiring member of another electricity storage module unit or to an external electrical component; and a unit base plate on which the electricity storage module is mounted. The unit base plate has a plurality of routing grooves that allow the wiring member to be routed such that a direction in which the wiring member is routed is changeable.
