BATTERIEANORDNUNG

摘要

A battery assembly which has a number of battery modules (16). For manufacturing, a battery module (16) is built in a battery case (10) having a fixed bulkhead (14) and a middle bulkhead (20) such that the module (16) penetrates the bulkheads (14) (20) via a battery holding opening (18) and a battery passing opening (22). The battery module (16) consists of batteries (12), with the connection parts of the batteries (12) held and supported by the battery holding openings (18) of the fixed bulkhead (14). A cooling/warming medium which flows upward is blocked or the cross sectional area of the cooling/warming medium flow is adjusted by a turning projection (38) so that the batteries (12) are effectively cooled or warmed irrespective of their vertical positions. A separately formed middle bulkhead (20) can facilitate manufacturing and assembling of the assembly. Batteries (12) can be more effectively cooled or warmed by using a smaller number of parts at a smaller number of assembling steps. The battery assembly is adaptable for being mounted on an electric motor vehicle, such as an electric motorcar.
