Embodiment Construction

[0023] figure 1 The housing system according to the invention is shown with a housing 10 , a pump 20 and a container 30 . The housing 10 includes an interior chamber 12 sized and proportioned to receive a battery, for example a battery of a certain battery type. The housing 10 comprises a double wall 14, 14', wherein the inner side 14' of the double wall comprises an inner wall section 16' and the outer wall of the double wall comprises an outer wall section 16. The double wall is circumferential and delimits an associated intermediate chamber 18, which is constructed between the inner wall 14' and the outer wall 14. The intermediate chamber 18 is substantially closed, wherein the opening 19 is provided with a fluid connection for filling and emptying the intermediate chamber 18 .

[0024] A pump 20 is connected to this connection 19 , which pump is in turn connected to a container 30 . The pump 20 can be operated in both directions and thus pumps water 32 of the conta...

Abstract

The invention relates to a thermally insulated housing system having a housing, which has an inner chamber configured to receive a high capacity accumulator. The housing according to the invention comprises a double wall in which there is a gap, wherein the gap is connected to the inner chamber in a thermally conductive manner by means of at least one inner wall section of the double wall. The gap is connected to the surroundings of the housing by means of at least one outer wall section of the double wall and is completely sealed except for a liquid connection. The housing system further comprises a liquid pump connected to the fluid connection and a liquid tank having liquid. The liquid tank is connected to the inner chamber via the liquid pump. The liquid pump is designed to control the fill level of the liquid in the gap between the wall sections of the double wall. The invention further relates to a method for the controlled cooling of a high capacity accumulator. The high capacity accumulator is arranged in an inner chamber of a housing having a double wall, within which a gap extends. The high capacity accumulator is connected to an inner wall section of the double wall in a thermally conductive manner by means of the arrangement. Heat transfer from the high capacity accumulator via the inner wall section and via an outer wall section of the double wall adjacent to the surroundings of the housing to the surroundings is controlled by changing a fill level of a liquid in the gap which extends between the inner and outer wall section.

Description

technical field [0001] The invention relates to a thermally insulated housing system for the controlled temperature treatment of accumulators, in particular for high-power accumulators. The invention relates in particular to the use of the housing system according to the invention and to a method for cooling a traction battery of an electrically driven vehicle. Background technique [0002] Electrical energy stores such as batteries are based on electrochemical conversion processes, so they are particularly sensitive to temperature. Excessively low temperatures lead to strong power disturbances, and high temperatures result in damage caused by premature aging, which is associated with continuous power disturbances. The battery temperature is usually determined by the surrounding environment as well as by its own heat loss. It is known to use active elements such as Peltier elements or also active compressor-driven refrigeration units for temperature control. But these sol...
