TEMPERATURE-CONTROLLED BATTERY

摘要

The temperature-controlled battery, which is intended in particular as an energy source of a vehicle drive, has numerous flat battery cells (17), which are electrically interconnected and which are combined parallel to each other and are distributed in several battery chambers (9-12) in a thermally insulated battery housing (3) to form cell packages (16). Spacers (18) are arranged between the battery cells. A flowable first heat-transfer medium in contact with the battery cells (17) is enclosed in the battery housing (3). The first heat-transfer medium exchanges heat with a second heat-transfer medium enclosed in a channel system (22, 23) by means of heat-transfer surfaces (22, 23) enclosed in the battery housing (3). Said channel system (22, 23) has a supply line and a discharge line leading out of the battery for the temperature-controlled exchange of heat outside the battery. For forced convection at the battery cells (17), at least one pump (21) is enclosed in the battery housing (3). Said pump has a flow connection to the first heat-transfer medium on the supply and outlet sides. The battery can be particularly highly loaded due to the thus substantially improved and uniform cooling of the battery cells (17).
