Title:
BATTERY UNIT AND ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP2023038041
Kind Code:
A
Abstract:
To provide a novel technique for a battery unit having high design flexibility.SOLUTION: The battery unit is provided, including: a core pack which houses a battery cell; and an outer circumference member which covers the outer periphery of the core pack. The outer circumference member has lattice structure in which a plurality of grids are periodically arranged between an inner side surface on a side closer to the core pack and an outer side surface on a side far from the core pack. The inner side surface includes at least one inner hole for communication between a space in which the core pack is arranged and the lattice structure. The outer side surface includes an outer hole portion which enables the outflow of fluid from the space to the outside through the inner hole and the lattice structure, and also restricts the inflow of fluid from the outside to the lattice structure. The outer circumference member is configured to seal the core pack hermetically in a portion excluding the outer hole portion.SELECTED DRAWING: Figure 2A
