Benefits of technology

[0005]The cooling body can dissipate heat losses arising in the flat cells and thus increases the reliability and the service life of the energy storage unit. A configuration made of a plastic material enables simple and inexpensive manufacturing and is, on top of that, advantageous with regard to saving weight.
[0024]According to another embodiment, the energy storage unit has at least one coolant duct for supplying the hollow spaces with coolant, wherein the coolant duct opens into a coolant inlet at a first end face of the energy storage unit and into a coolant outlet at a second end face of the energy storage unit. All the hollow spaces associated with the energy storage unit can thus be connected in a simple manner to a common coolant supply.

Problems solved by technology

However, the cooling devices used conventionally for heat dissipation are expensive and require relatively much construction space, which especially in the field of automobile engineering is very limited.

Embodiment Construction

[0030]FIG. 1 shows a perspective view of two energy storage units 10, 10′. The two energy storage units 10, 10′ are joined together in order to form a superordinate unit. Within the framework of a modular concept, thus, depending on the application requirement, any number of energy storage units can be joined together in a line or be combined to form a two- or three-dimensional matrix in order to eventually constitute a vehicle battery, for example.

[0031]Each of the energy storage units 10, 10′ comprises a plurality of prismatic cells / flat cells 12 arranged in parallel to one another in a stack. The cells 12 can, for example, be lithium ion accumulator cells or double-layer capacitor cells (“supercaps”). Each of the individual cells 12 has two electrode tabs 14a, 14b protruding from the narrow side thereof. A plate-shaped interconnection board 18 serves for an electrical through-connection of the cells 12. In the case of the exemplary embodiment described, the cells 12 are serially ...

Abstract

An energy storage unit for storing electrical energy comprises a plurality of stacked flat cells, each having protruding electrodes. A cooling body of the energy storage unit is heat-conductively connected, at least in sections, to the flat cells. The cooling body at least partially consists of a plastic material and has openings through which the electrodes extend.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to an energy storage unit for storing electrical energy comprising a plurality of stacked flat cells, each having protruding electrodes.[0002]Energy storage units comprising a stack of flat cells (so-called prismatic cells or pouch cells) are used, for example, in electrically driven motor vehicles. Due to the high voltages and current intensities occurring during operation, considerable heat amounts can develop which have to be dissipated in order to avoid overheating of the energy storage unit. However, the cooling devices used conventionally for heat dissipation are expensive and require relatively much construction space, which especially in the field of automobile engineering is very limited.[0003]It is therefore an object of the invention to provide heat dissipation for energy storage units of the above-mentioned type in a manner which is as efficient and as compact as possible.SUMMARY OF THE INVENTION[0004]This ob...
