Electric storage battery casing e.g. for automobile battery, has cooling air stream directed across battery cells filtered for removal of humidity and moisture

摘要

The battery casing (1) contains a number of electrochemical battery cells (4) over which a cooling air stream is passed between an inlet opening (2) and an outlet opening (3). The inlet opening has an associated air filter for removing humidity or moisture from the supplied cooling air stream, e.g. via a pair of filter elements at the opposite ends of an air inlet pipe (7).
