摘要： A cell housing, such as for a backpack battery pack, includes a first wall, a second wall, and a cell retention structure there-between, wherein the cell retention structure is configured to retain battery cells arranged in a matrix of rows and columns such that the longitudinal axis of each battery cell is substantially parallel to the longitudinal axes of the other battery cells. A plurality of connectors are located on the exterior of the cell housing and are electrically connected to the battery cells through openings in the first and second walls of the cell housing. The connectors electrically connect the cells in each row in parallel and the cells in each column in series. The connectors may comprise unitary connectors that electrically connect the positive terminals of at least two cells of one row of cells to each other and also to the negative terminals of at least two cells of another row of cells. At least one fuse may be disposed in the connectors electrically between at least one cell and a plurality of the other connected cells. A relay may be connected in series between a printed circuit board and the battery cells to disconnect the cells from the load upon the occurrence of a predetermined event.

摘要： A battery pack may include a plurality of cells, a cell connector assembly, and a common output. The cell connector assembly may be disposed to contact at least selected ones of the plurality of cells to facilitate parallel connection of contacted cells. The common output may be electrically coupled to the cell connector assembly to receive a combined output from the plurality of cells. The cell connector assembly may include a plurality of metallic arms arranged in a hierarchical structure including at least two levels each having at least one arm, such that the cell connector assembly defines a plurality of current paths from each of the contacted cells to the combined output. The plurality of current paths are substantially equal to each other in length.

摘要翻译： 电池组可以包括多个单元，单元连接器组件和公共输出。 电池连接器组件可以设置成与多个电池中的至少一个电池接触，以便于接触电池的并联连接。 公共输出可以电耦合到单元连接器组件以接收来自多个单元的组合输出。 电池连接器组件可以包括以分层结构布置的多个金属臂，其包括至少两个级别，每个级别具有至少一个臂，使得电池连接器组件限定从每个接触电池到组合输出的多条电流路径 。 多个电流路径的长度基本相等。
