  • Battery module for forming a battery for a vehicle
  • the present invention relates to a battery module for forming a battery for a vehicle, preferably a traction battery for an electric vehicle.
  • Electrochemical energy stores in particular lithium-ion batteries, have a limited operating temperature range. Outside of this range, such battery cells lose their performance, age faster or reach safety-critical states. For this reason, battery cells in many applications, especially lithium-ion batteries in electric and hybrid vehicles, are actively thermally conditioned, i.e. heated or cooled as required, in order to remain within the optimum operating temperature range.

  • Such battery systems can also include a housing accommodating the battery modules, electrical interconnections and a battery management system.

  • temperature control elements have, for example, a flat, planar geometry.
  • the battery cells are thermally connected to this temperature control element, for example, by a flexible, thermally conductive mat (“gap pad”) or by a liquid, pasty, partially hardening material (“gap filler”).
  • Gap pad flexible, thermally conductive mat
  • Gap filler liquid, pasty, partially hardening material
  • Gap fillers that harden to a lesser extent can migrate, which can drastically reduce the heat conduction from the temperature control element to the battery cells. Furthermore, the dismantling of hardening, adhesive gap fillers is difficult if not impossible. In addition, there is a risk of air bubbles being trapped with gap fillers. As a result, another component is required for electrical insulation and the air bubbles locally increase the thermal resistance, which can lead to overheating of individual cells.

  • a battery module includes a cell holder that can hold a large number of battery cells.

  • the distance between the battery cells and the temperature control element is influenced by a large number of component tolerances.
  • the flatness of the heat exchanger, the height of the supporting structure or the flatness of the cell holder influence the gap between the cell bottom and the temperature control element.
  • the distance between a battery cell and the temperature control element can vary by several millimeters, for example, depending on the component tolerances in the respective battery.
