DESC:FIELD OF THE INVENTION
[0001] The present invention relates to a system and a method to achieve uniform flow rate of fluid for Energy Storage System (ESS) by providing equal effective lengths of multiple conditioning channels for different stack profiles.
BACKGROUND OF THE INVENTION
[0002] An Electric vehicle battery (EVB) also known as a traction battery or Energy Storage System (ESS) is a rechargeable battery that is used to power the motors of the vehicle which provide driving force to the vehicle. Many electric vehicles are capable of being charged at very fast rates. This causes the battery to heat up significantly.
[0003] The high temperature of the battery reduces the lifespan of the ESS and increases the risk of thermal runaway. The heated Energy Storage System (ESS) may lead to the deterioration of electronic components placed inside the vehicle in terms of life and increases the chances of their failure during operation leading to fires.
[0004] Therefore, ESS cooling is necessary to reduce the temperature during fast charging. One of the challenges encountered in energy storage systems (ESS) cooling is maintaining a uniform flow rate of fluid, typically coolant or thermal management fluid, throughout the ESS. This fluid is used to regulate the temperature of the energy storage system components, ensuring their efficient and safe operation. Irregular flow rates can lead to localized hotspots, inefficient cooling, and potential damage to the energy storage system, ultimately impacting the vehicle’s performance and longevity.
[0005] Further, Electric vehicles’ ESS packs mainly have two configurations. First is a cell to pack and second is a module to pack. In cell to pack, ESS cells are directly placed on an ESS casing and connected electrically and mechanically to create the ESS pack. However, in the module to pack architecture several cells are grouped to form the module and several modules are grouped together to form various such packs which are then assembled according to the requirements. The ESS packaging architecture is required for electrical isolation of the cells, protection of the cells from automotive vibrations while vehicle is being driven and to maintain thermals of the cells in order to keep the cells within optimum operating temperatures.
[0006] To maintain the optimum temperatures of such modules, there are various designs and methods. Large ESS packs can be either conditioned through fluid or actively conditioned. This helps in maintaining the cells within the ESS pack at an optimum temperature band. Active conditioning system is very critical for the ESS packs otherwise at temperatures which are not optimal, the cells degrade faster. In large ESS packs active conditioning of different cells may be differential as due to various architectural constraints. It is imperative that during the conditioning process, that the fluid is able to condition uniformly each of the cell within the ESS pack. This may be achieved by maintaining a constant fluid flow rate across each cell or module. Existing solutions often rely on rudimentary flow control mechanism that does not adequately address the complexities of fluid dynamics within the energy storage system.
[0007] In an example, the patent application US2016365612A1 discloses energy storage systems and methods for operating energy storage systems. The systems and methods can flow a thermal management fluid through a structural member, such as a frame, of the energy storage system to maintain the system at an operating temperature, operate the system in an energy efficient manner, extend the operating lifetime of the system, provide emergency operation features and/or enable the system to operate during periods in which it may provide optimum or otherwise enhanced value.
[0008] In another example, the patent application KR20220050710A discloses an energy storage facility capable of uniformly controlling the internal temperature, and more particularly, the case, which is provided in the inner space of the case and spaced apart a plurality of battery modules horizontally and vertically. The rack body to be loaded, the air conditioning unit located on the inner surface of the door of the case, the heat fluid duct located inside the case and connected in communication with the air conditioning unit, a temperature sensor located in the battery module and a control unit electrically connected to the temperature sensor; Including, the thermal fluid duct relates to an energy storage facility characterized in that the thermal fluid supplied from the air conditioning unit is guided to the battery module.
[0009] However, none of the above available solutions provide uniform cooling of components of the energy storage system in a cost-effective way. In addition, the existing solutions have increased the complexity of modules that inscribe cells in a pack.
[0010] Hence, there is a compelling need for an innovative energy storage system architecture that addresses the shortcomings of conventional technologies and ensures enhanced efficiency, reliability, and flexibility. The present invention aims to overcome the technical problems of prior art by providing an efficient energy storage system (ESS) to achieve uniform flow rate of coolant in the energy storage system for conditioning of cells by providing equal effective lengths of a plurality of conditioning channels for different stack profiles.
