Embodiment Construction

[0019] according to figure 1 with figure 2 , the energy storage device 1 according to the invention has at least one energy store 2 , here a plurality of energy stores 2 , which in the present case are arranged parallel to one another. In particular, the energy store 2 can be designed in this case as a so-called pouch cell or a pouch, whereby flexibility can be increased in particular and previously unavailable space can also be used. Furthermore, the energy storage device 1 according to the invention has a temperature control device 3 for cooling / heating the energy store 2 , in particular for cooling the latter (energy store). Each of the energy stores 2 has at least two battery conductors 4 via which, for example, an electrical connection to an electrical consumer takes place. Furthermore, the temperature control device 3 has a spray chamber 5 in which at least one of the energy stores 2 is accommodated together with its battery conductor 4 . The entire battery system ca...

Abstract

The invention relates to an energy storage device (1) having at least one energy store (2) and having a temperature control device (3) for cooling / heating the at least one energy store (2), wherein the at least An energy store (2) has two battery conductors (4), wherein the temperature control device (3) has a spray chamber (5), at least one energy store (2) is housed with its battery conductor (4) In the spray chamber, there is provided a fluid distribution system (6) via which a dielectric temperature control fluid (7) can be injected to at least the battery conductor (4).

Description

technical field [0001] The invention relates to an energy storage device having at least one energy store and a temperature control device for cooling / heating the energy store. The invention also relates to a motor vehicle having at least one such energy storage device. Background technique [0002] Due to the growth of electric vehicles, the demands on the range and thus the power of the electrical energy store are also increasing. Therefore, in order to be able to increase the power, today's electrical energy stores are already temperature-controlled, ie cooled or heated, and thus kept within a temperature window that is optimal with regard to power output. In this case, for cooling the energy store, separate heat exchangers in the form of one or more plates through which a fluid can flow have hitherto been used, irrespective of the individual battery type. Depending on the requirements and the necessary cooling power, this can be combined with additional parts of heat-c...
