Electrical energy storage device for motor car e.g. hybrid car, has electrically insulated cooling channel that primarily transfers heat to battery cells through heat-conducting element and secondarily transfers heat to cell terminals

摘要

The storage device (1) has identically aligned battery cells (2) that are respectively set with cell terminal (3) including positive terminal (4) and negative terminal (5). A heat-conducting element (6) is arranged between battery cells which are formed as bag cells. The coolant leading edge side of the heat-conducting element is provided with an electrically insulated cooling channel (7) which transfers heat to the battery cells through the heat-conducting element primarily and transfer heat to the cell terminals secondarily. An aluminum foil (10) is enclosed in the battery cell.
