Battery module with improved interface component for electric vehicles
A recently granted patent (Publication Number: US12015174B1) discloses a system for battery current collection, featuring a current collector with multiple layers, a busbar, and an interface that protrudes past the layers to connect with the busbar via a weld. The interface, made of an electric conductor material, forms a tab extending beyond the battery edge and is in contact with the busbar. This innovative system allows for efficient electrical contact between the current collector and the busbar, enhancing the overall performance of the battery system.
Furthermore, the patent includes methods for implementing this system, such as welding the interface onto the surface of the busbar and configuring the interface to bend around the edge of the busbar. The system is designed to be integrated into battery packs and electric vehicles, providing a reliable and effective solution for connecting current collectors and busbars. With a focus on optimizing electrical connections within battery systems, this patented technology showcases advancements in battery design and integration, potentially leading to improved efficiency and performance in electric vehicles and other battery-powered applications.
