Abstract
Disclosed herein is a case which protects a plurality of flexible lithium polymer unit cells, has a compact structure to reduce volume, has a simple assembly process, and minimizes heat generated during a high-power charging or discharging operation. The battery case includes a pouch support frame to support a pouch of a unit cell having the pouch and electrode terminals. A heat radiating part having the shape of a shelf is provided on a surface of the pouch support frame, and defines a space for dispersing heat generated from the pouch. A terminal support having the shape of a wall is provided on an edge of the heat radiating part, thus supporting the electrode terminals of the unit cell.
Claims6
A battery case, comprising:
- a pouch support frame to support a pouch of a unit cell having the pouch and electrode terminals;
- a heat radiating part having the shape of a shelf, provided on a surface of the pouch support frame, and defining a space for dispersing heat generated from the pouch;
- and
- a terminal support having the shape of a wall, provided on an edge of the heat radiating part, thus supporting the electrode terminals of the unit cell.
A battery case comprising a pair of cases, each of the cases comprising:
- a pouch support frame to. support a pouch of a unit cell having the pouch and electrode terminals;
- a heat radiating part having the shape of a shelf, provided on a surface of the pouch support frame, and defining a space for dispersing heat generated from the pouch;
- and
- a terminal support having the shape of a wall, provided on an edge of the heat radiating part, thus supporting the electrode terminals of the unit cell, wherein the cases are connected to each other via the pouch support frame and a frame connection part of each of the cases.
