BATTERY PACK: abstract simplified (18130350)

• This abstract for appeared for patent application number 18130350 Titled 'BATTERY PACK'

Simplified Explanation

This abstract describes a battery pack that consists of battery cells and a spacer. The battery cells have electrode bodies and cases that are sealed together. The cells are arranged in a specific direction, and the spacer is placed between the cases of adjacent cells. The battery cells are bound together with pressure. The electrode body has a flat portion, and the spacer has a base plate with projections that extend towards the adjacent cell's case. One of these projections, called the top projection, applies pressure to the adjacent cell's case at a position above the flat portion of the electrode body where the sealing is closest.

Original Abstract Submitted

A battery pack includes battery cells and a spacer. Each battery cell includes an electrode body and a case accommodating the electrode body in a state sealed by a sealing portion. The battery cells are arranged in an arrangement direction. The spacer is arranged between the case of one of the battery cells and the case of an adjacent battery cell. The battery cells are bound together in a state in which a binding pressure is applied to the battery cells. The electrode body includes a flat portion. The spacer includes a base plate and projections projecting from the base plate toward the case of the adjacent battery cell. The projections include a top projection that presses the case of the adjacent battery cell at a position located upward from an upper edge of the flat portion where the sealing portion is the closest.
