Abstract: A battery assembly includes a plurality of battery cells each including a cell tab and a bus bar connected to the cell tabs of adjacent battery cells. The bus bar including a pair of 180 degree bend regions that each define a channel for receiving a respective cell tab and a cut-out region defining an opening having opposing edge portions that allows direct access to the cell tab within the cut-out region. A weld line connects the cell tab to at least one of the opposing edge portions within the cut-out region.

Abstract: A battery module includes a plurality of battery cells and a flexible bus. Each of the battery cells has a main body, a first terminal disposed on the main body, and a second terminal disposed on the main body. The main body includes active material configured to generate power from an electrochemical reaction. The bus includes an electrical current harness configured to conduct an electrical current through the battery module and a battery management system configured to detect and transmit status information, as well as selectively control a charging and a discharging of at least one of the battery cells.
