CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
The present application claims priority from the Indian provisional patent application, having application number 202241030562, filed on 27th May 2022, incorporated herein by a reference.
FIELD OF INVENTION
The present invention, in general, relates to an electric vehicle, and more particularly, relates to assembly of a battery module of the electric vehicles.
BACKGROUND OF THE INVENTION
The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
With the ongoing commercialization of electric powered vehicles, the market for internal combustion (IC) engine powered vehicles is decreasing day-by-day. Electric powered vehicles are much more efficient in terms of performance, range, and produce no carbon emissions as compared to IC engine powered vehicles. The performance and quality of the electric vehicles are heavily reliant on a battery module deployed for use. The most essential factors affecting the battery module performance are the battery module's insulation, thermal conduction, and structural resistance to avoid roadside jerks. The battery module's insulation, thermal, and structural requirements are mainly depending on the assembly architecture of the battery.
Further, the electric vehicle battery consists mainly of two different types of assembly architecture, which are cell to pack and module to pack. In cells to pack architecture, the cells are directly placed on the battery casing and connected electrically and mechanically to make the battery pack. In module to pack architecture, the cells are grouped and made into modules which are then assembled according to the battery pack.
Further, if sufficient insulation between the cells or modules is not maintained, the danger of electric short-circuiting and fire hazard increases. Thus, there is a need for the assembly architecture that ensures electrical insulation between the cells or modules.
The battery module's temperature may vary depending on the load, ambient temperature, charge rate and discharge rate, thermal design. The temperature of the battery module should be kept under limits. It should not exceed the limits specified by cell characteristics. The heat generated by the current flow and the electrochemical reaction during the work process may cause the battery pack temperature to rise if the temperature of the battery module is too high. If the battery cell temperature of the battery module is inconsistent, the accumulation of heat generated by the battery module may cause uneven temperature everywhere, affecting consistency, reducing charge and discharge cycle efficiency, and even leading to thermal runaway of the battery cells. Thus, there is a need for the assembly architecture that ensures the thermal consistency of the battery module and keeps the cells under the right operating temperature.
Furthermore, roadside jerks experienced by the vehicle may damage the cell modules of the battery. Thus, there is a need for the assembly architecture that ensures structural stability of the battery module.
To address these needs, the state-of-the-art module architecture uses sheet metal welded with foam pads between the cells to hold the cells and hold it structurally. Further, conventional designs like VDA (Verband der Automobile industries - Association of German Automobile Manufacturers) modules are cooled only by using bottom cooling method which is a separate cooling system from the module packaging. Furthermore, battery manufacturing companies use large bottom cooling heat sinks either by using extruded cooling channels welded with each other or by using brazed heat sink methods. In a nutshell, all the above-mentioned architectures use separate systems for taking care of thermal consistency, electrical isolation and structural mounting individually.
Therefore, there was a long-felt need to resolve the above-mentioned problems related to the battery of an electric vehicle by enabling an electrically insulated, uniform thermal conductive and vibrational resistive battery module.
