Benefits of technology

[0003]In contrast, the battery test rig according to the invention has the advantage that it is possible to test or examine batteries with an increased level of safety. According to the invention, high-efficiency cooling can be carried out in this case if necessary. This is achieved, according to the invention, by virtue of the fact that the battery test rig comprises a cooling apparatus which is connected to a regulation unit. A sensor device is connected to the regulation unit in order to monitor the battery. If t

Embodiment Construction

[0014]A battery test rig 1 according to one preferred exemplary embodiment of the invention is described in detail below with reference to FIG. 1.

[0015]As can be seen from FIG. 1, the battery test rig 1 comprises a test cell 3 in which a battery 2 to be checked is arranged. In this case, the battery 2 is held in a holder 13 which comprises a plurality of narrow carriers. The use of the narrow carriers makes it possible, in particular, to avoid the test results being distorted by thermal loads. Furthermore, good accessibility to the battery 2 to be checked can be ensured.

[0016]The battery test rig 1 also comprises a regulation unit 4 and a cooling apparatus 7. A pressure sensor 5 and a temperature sensor 6 are also provided and are fixed to an outer side of the battery 2. The pressure sensor 5 and the temperature sensor 6 are connected to the regulation unit 4 via lines 5a and 6a. In this case, the reference symbol 2a denotes an electrical connection between the battery 2 and the reg...

Abstract

The present invention relates to a battery test rig, comprising a test cell (3) in which a battery (2) to be tested is arranged, a holder (13) which is arranged in the test cell (3) and is able to hold the battery (2), a regulation unit (4) which can be connected to a battery (2) arranged in the holder (13), at least one sensor device (5, 6) for monitoring the battery (2), wherein the sensor device (5, 6) is connected to the regulation unit (4), and a cooling apparatus (7), which is connected to the regulation unit (4) and is designed to cool the battery (2) in the test cell (3) from the outside in a hazard situation.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a battery test rig which is used to examine or check different batteries.[0002]The function and load limits of batteries are checked, for example, as part of development and production. However, a considerable potential hazard may result in this case. In particular, in the case of excessive charging or discharging or else in the case of other external environmental influences, for example a temperature increase, gaseous cleavage products, which may result in a pressure increase, may be produced in the event of reactions between the existing battery materials (cathode, anode, electrolyte). Furthermore, exothermic reactions may entail a further supply of heat. Consequently, the battery may be destroyed by an explosion. As a result, work on battery test rigs may be hazardous. It would therefore be desirable to have an improved level of safety, in particular, for the employees working with battery test rigs.SUMMARY OF THE...
