Definitions

  • the invention relates to a pin and/or plate type structure that can be easily installed, which increases the efficiency of the cooling plate that provides cooling of the battery modules used in electric vehicles, which ensures a homogeneous heat distribution inside the battery pack, which reduces battery aging by preventing the batteries in the module from overheating, and which increases the efficiency of the cooling plate.
  • Liquid cooling systems that use a cooling plate become more useful in hot weather conditions.
  • cooling plates can be placed between, under, or above the battery cells. Cooling fluid is passed through these plates and heat is transferred by contact of the battery cells with the plate and then the cells are cooled.
  • the advantages of using liquid cooling in electric vehicles are the high thermal conductivity of the cooling liquid, its ability to keep the battery in the optimum operating temperature range in all climatic conditions due to its high heat transfer coefficient, its compactness, and the fact that the battery pack takes up less space compared to the air-cooling system.
  • the number of channels, inlet mass flow rate, flow direction, and channel width can be considered as important factors affecting its efficiency.
  • the invention relates to a pin and/or plate type structure that provides a homogeneous distribution of heat into the battery cells and thus provides homogeneous cooling in the liquid cooling system used in batteries of electric vehicles.
  • the system subject to the invention has a structure that will facilitate the transfer of heat by the cooling plates to the cells and ensure homogeneous cooling.
  • This structure includes a pin and/or plate type structure with various cross-sectional shapes that contact the cooling plate and ensure homogeneous distribution of heat within the battery cells.
  • This pin and/or plate type structure can be applied to battery modules containing any battery type, whether cylindrical or pouch/prismatic type, with the possibility of easy assembly.
  • the pin and/or plate type structure comes into contact with any type of cooling plate, ensuring homogeneous cooling of the batteries not only the parts that the cooling plate comes into contact with, but also the parts that it cannot contact. LIST OF FIGURES

  • FIG. 3 Schematic View Showing the Position of the Pin and/or Plate Type Structure Subject to the Invention, Integrated into the System in addition to the Standard Battery Cooling Plate, within the Battery Package
  • FIG. 4 Exploded View of the Mounting Set Showing the Pin and/or Plate Type Structure of the Invention Integrated into the Standard Battery Cooling Plate Figure 5.
  • the invention is based on battery cells (2) that provide efficient cooling by transferring the heat within the battery cells (2) placed within the battery module casing (1 ) homogeneously to the cooling plate (3), and the heat of the cooling plate (3) to the battery cells (2) homogeneously. It is characterized by a pin and/or plate type structure (4) placed between the cooling plate (3) in contact with the cooling plate (3).
  • the invention relates to the structure introduced to solve the homogeneous cooling problem experienced in liquid cooling systems used to cool battery modules used in electric vehicles and energy storage systems.
  • battery modules basically consist of a battery module casing (1 ), battery cells (2) electrically connected in parallel and/or series within the battery module casing (1 ), and a cooling plate (3) used to cool these batteries.
  • the battery cells (2) are placed inside the battery module casing (1 ) and the cooling plate (3) is placed on this casing in such a way that it touches one surface of the battery cells (2). Thanks to the cooling liquid circulated through the cooling plate (3), the battery cells (1 ) are cooled by heat transfer from the surface in contact with them.
  • Our invention consists of pin and/or plate type structures (4) that form a three-dimensional contact surface with battery cells (2) that work in contact with the battery cooling plate (3). These structures can be manufactured either separately from the cooling plate (3) or as a single piece. Pin and/or plate type structures (4) consisting of different geometries enter the gaps between each other inside the battery cells (2) and the heat in the cooling plate (3) is delivered homogeneously to all parts of the battery cells (2) to provide the widest contact surface. In this way, battery packs are cooled much better.
  • pin and/or plate type structures (4) are extending structures consisting of various complex shapes located between the battery cells (1 ) and working by contact with the cooling plate (3). Its purpose is to carry the heat from the cooling plate (3) into the battery pack. These pin structures (4) are suitable for use in pouch, radial, and prismatic battery cells of different geometries (1 ).
  • the pin and/or plate type structure (4) contains at least one of the different geometric forms such as star, twist, cylindrical, rectangular, quadrangular, trapezoidal, and prism.
  • the pin and/or plate type structure (4) can be integrated into the cooling plate (3) or can be adapted with an additional structure to the cooling plates (3) that do not already contain the pin and/or plate type structure (4).
