  • the invention also relates to an electric or hybrid vehicle having such an electrical power supply device.
  • battery cell modules based on lithium-ion batteries When used in motor vehicles, battery cell modules based on lithium-ion batteries must be cooled and heated to protect the individual battery cells from aging too quickly. For electric vehicles sometimes high ranges and fast charging capabilities are required. In particular with electric energy storage devices, this leads to very large battery housings / modules.

  • the fluid can be tempered via a heat exchanger arranged in the fluid circuit.
  • it is customary to integrate the battery cell module directly into the fluid circuit, so that it is thus partially surrounded by the fluid.
  • the components of the battery cell module that are in thermal contact with the fluid are made of an electrically conductive material, it is of great importance that there is no electrical short circuit through the fluid, which is typically electrically non-conductive , electrically conductive impurities can be generated.
  • the basic idea of the invention is accordingly to arrange a sensor device in the fluid circuit which can detect any impurities present in the fluid, typically in the form of dirt particles. If such impurities are detected by the sensor device, the fluid is guided through a filter device provided in the fluid circuit, which filters out said impurities from the fluid. In this way, it is ensured that no electrically conductive dirt particles remain in the fluid and can cause an electrical short circuit in the battery cell module to be tempered.
  • Essential to the invention of the temperature control device presented here is a bypass provided in the fluid circuit, via which the fluid can be conducted past the filter device, as long as no sensor is provided by the sensor device Dirt particles or only a concentration below a specified limit value can be detected. In this way, an unnecessarily high pressure loss in the fluid caused by the flow through the filter device is avoided. This in turn leads to an improved efficiency of the tempering device during heat exchange with the tempering battery cell module.
  • said bypass can be realized by means of a switchable valve device, via which the fluid can be conducted past the filter device.

  • the sensor device is designed to detect the water content of the fluid.

If the sensor device is capable of detecting the water content of the fluid, it is also possible for the water present in the fluid to be at least partially, ideally even completely, removed from the fluid as it flows through the filter device.
