1 TARIFF HEATING ELEMENT WITH INTEGRATED FOAM MATERIAL. A BATTERY CELL Technical Area 5 This invention optimizes battery life through cell pressure and temperature control. foam material with an integrated heating element is used for this purpose. It is related to a battery cell. Previous Technique In electrochemical batteries, the basic unit is the cell; the cells are in standby mode and charge-discharge mode. or expands and contracts as a result of chemical reactions. This expansion and contraction... Shrinkage can lead to delamination of internal battery cells and components, and even damage to the battery itself. This can cause deformation of the packaging. This situation affects the effective thermal management of the battery. This further shortens its lifespan and, in worst-case scenarios, leads to thermal runaway. It opens. Optimum battery life, supported by 20 'breathing' battery during discharge and charge cycles. This is achieved by applying a moderate level of physical pressure. Pressure ensures that electrical and thermal connections remain in contact throughout this period. It ensures that lithium-ion batteries operate safely and efficiently and at maximum capacity. to reach its service life within the temperature range specified by the cell manufacturer. It is necessary to maintain heating and cooling in the thermal management of battery packs. It is that important. Achieving optimum charge / discharge performance as a result of heating. It is possible. Therefore, the exposure that batteries are subjected to throughout their lifespan... Both pressure and temperature values need to be kept within the optimum range. The volume of batteries increases during charging and discharging. This volumetric increase is 30 Foam is added between the battery cells to control changes. This foam 2 by optimizing the material, volumetric change and possible compression that may occur It is calculated. However, the temperature of the batteries depends on the cooling-heating plate on the cells. It is attempted to be controlled by rotating the liquid on top. However, this type In these applications, high temperature differences occur between the cells, which affects both charging. It also causes a limitation in the capacity of the cells during discharge. 5 Therefore, battery life is optimized through cell pressure and temperature controls. foam material with an integrated heating element is used for this purpose. It appears to be detected by a battery cell. In the Chinese patent document numbered CN206349464, which is included in the known state of the art... The text refers to a power battery combination type thermal management system. The invention that is the subject of the patent document is a thermal combination type power battery. It relates to the management system. The system consists of a battery box, batteries, and phase changeover. It consists of foam and metal foil. 15 foam metal is placed in the middle of the battery case. It is fitted with holes in this foam metal where the batteries will be placed. These holes are located and the batteries are placed in these holes. The battery and foam metal The gap between them is filled with phase change material to ensure thermal management. The batteries are arranged in groups inside the box, and metal foil is wrapped around the batteries. It is wound at an angle, and the number of these winding layers is 20 from the center of the box. It decreases towards the outer layers. Wings located at the top of the metal foil. (Fin), exiting the battery case, comes into direct contact with the air and generates heat. It enhances transfer. These wings are arranged regularly between adjacent layers of metal foil. They are placed at intervals. Thanks to this system, heat transfer within the battery is efficient. The temperature difference between the center and periphery of the battery case is accelerated to 25°C. While the number of components is reduced, the system's simple structure and low cost are preserved.
