Battery i.e. lithium ion battery, for use in e.g. hybrid vehicle, has cooling device with individual plate-shaped cooling cells that are fixed between two battery cells by heating zones, and cooling zones protruded outward between cells

摘要

The battery (11) has a set of plate-shaped battery cells (12) arranged in parallel to each other, where the cells include a cooling device according to a heat pipe principle. Cell-distant-cooling zones (17) are filled with a low evaporating working medium. The cooling device includes individual plate-shaped cooling cells (13) that are arranged parallel to each other, where the cooling cells are fixed between two battery cells by heating zones (16), and the cooling zones are protruded outward between the battery cells. The cooling zones are arranged in a cooling air stream.
