Battery holder, battery receiving case, battery pack, electricity accumulation system, and electronic instrument

Abstract

The invention provides a battery holder, a battery receiving case, a battery pack, an electricity accumulation system, and an electronic instrument. The battery holder comprises a plurality of battery unit accommodating parts for accommodating battery units. Each deformation part and each space part are formed between outer peripheral surfaces of two battery unit accommodating parts, wherein the deformation parts generate elastic deformation due to transmission of external shocks, and the space parts is used for allowing elastic deformation of the deformation parts.

Description

technical field [0001] The present disclosure relates to battery holders, battery housing cases, battery packs, power storage systems using the battery packs, electronic devices, electric vehicles, and power systems usable for battery packs in electronic equipment, electric vehicles, electric tools, and the like. Background technique [0002] Lithium ion secondary batteries have been used which use doped and dedoped lithium ions. A plurality of batteries (also called cells or cells) of a lithium-ion secondary battery are connected to form a battery cell group. Batteries constituting the battery cell group are connected to each other to form a battery module. One or more battery modules are accommodated in the case, thereby forming a battery pack. Battery packs of lithium ion secondary batteries have been widely used in electronic equipment such as personal computers and mobile phones, electric vehicles, electric tools, and the like. [0003] In some cases, the impact forc...
