The invention relates to a method comprising a step of providing a cooling plate (2) having at least one exposed cooling channel designed for guiding a cooling fluid. The method further comprises a step of providing a mounting unit (1) designed for receiving and fixing at least one energy storage unit. The method finally comprises a step of connecting the cooling plate (2) to the mounting unit (1), whereby the at least one cooling channel is closed.

Description and scenario of usage:
Modern battery housings for high-voltage energy storage devices in electric vehicles must cover structural, electrical and thermal functions.

Solved problem with the invention:
So far, the functions "cooling" and "housing" in a battery housing have been implemented by separate components battery jacket and cooling plate. A combination of the "cooling" and "housing" functions can be achieved by connecting a central base plate with open cooling channels to a holding unit designed to hold and fix the Li-Ion cells or modules, forming a "closed", structurally supporting cooling base plate.

Advantages und USP with the invention:
This saves material for sealing a cooling channel, which reduces costs and at the same time the weight of the battery housing.

Financial information

The patent family comprises the following alive granted patents: EP2476160B1 (only FR, DE was kept by former owner Mahle), US9083009B2, CN102576916B, JP5604519B2 – thereby a big market size is covered.
All patent family members were granted without any restrictions. There were no oppositions against any of the family members. All fees are paid. The patent family was cited 11 times in total.
The functions "cooling" and "housing" combined in a battery housing have enormous effects on weight, cost and production time.
The invention perfectly meets the current trend of electric vehicle power supply and increasing battery efficiency at low cost. The patent family described was created as part of Behr GmbH & Co KG ‘s R&D work. Behr is a big German car supplier. The patents listed here originate from the field of Li-Ion cells, their low-cost, weight-optimized, modular design, cooling, connection/assembly. The area of thermal management and energy storage was one of the core projects there. This invention addresses key functions such as electrical contacting, thermal contacting and cooling at module level via uniformly defined module interfaces results in significant advantages in the very fast and simple exchangeability.
The acquisition of Behr by Mahle (another big car supplier) also resulted in the abandonment of Behr's original strategy of investing in battery cell production (pouch cells, see arrester patents) and in battery production as a whole (see patent family 1). The patent families described here fall within this period of Behr's original strategy.
Some of the patents from this area were transferred to one of the inventors involved (Prof. Dr. Herrmann) and are now for sale or licensing. For all the inventions described, prototypes or pre-series products were available that demonstrated the technical and economic feasibility.
The sale of the patent portfolio takes place against a bid – a detailed value calculation of each patent family member is available and may be provided on request.

There is no minimum bid even though the patent family was valued to a big sized 6 digit USD value.
