Portable battery assembly and container for battery

摘要

The assembly has an electrochemical element i.e. lithium ion cell, including a rechargeable battery (BK) that is enclosed by a closed battery housing and containers (BR) enclose the battery and are detached from the battery. The containers include a wall surface that encloses a part of the battery housing and include a thermal transmission coefficient varying opposite to the battery housing, where the wall surface is made of thermal isolated material. A supporting device is installed on the container, and supports the assembly at a body of a person.
