摘要： A battery pack may include a plurality of cells arranged substantially adjacent to each other such that longitudinal centerlines of each of the cells are aligned substantially in parallel with each other in a first direction, a physical cell connection assembly that includes a cell-retaining portion disposed to contact each of the cells to hold the cells in a housing, an electrical cell connection assembly that includes a plurality of cell connectors disposed to contact at least selected ones of the cells in groups to facilitate electrical connection of the cells associated with each of the groups, a contact portion of each of the cell connectors being disposed to electrically connect electrodes of at least two of the cells, and a printed circuit board (PCB) configured to monitor electrical parameters associated with the cells based on electrical communication between the PCB and the electrical cell connection assembly. At least one cell connector of the cell connection assembly may include a holding portion that engages the physical cell connection assembly and a fixing portion that extends substantially perpendicular to the plane of the PCB to engage the PCB to facilitate holding of the PCB relative to the physical cell connection assembly.

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.
