Embodiment Construction

[0030] Figure 1a Shown is a battery system 1 with a plurality of interconnected battery cells 2 and a device for regulating the temperature of the battery cells 2 which comprises two hollow bodies 3 through which a cooling medium flows and a plurality of heat conducting Element 5. exist Figure 1a The battery cell in the illustrated embodiment is a plurality of Li-ion cells electrically connected to each other (in Figure 1a not explicitly shown). The battery system is designed as an energy store for a drive in a hybrid vehicle, a plug-in hybrid vehicle and / or an electric vehicle.

[0031] A heat-conducting element 5 is arranged between two battery cells 2 and in each case on the outer side of an externally disposed battery cell 2 . The heat-conducting element 5 is here made of ceramic. As a design variant, however, the heat-conducting element, in particular coated with an electrically insulating lacquer layer, is made of aluminum or copper. exist Figure 1a Each heat-cond...
