摘要： A battery pack may include a cell housing configured to retain a plurality of battery cells, and a plurality of cell reception slots within the cell housing to receive respective ones of the battery cells. The cell reception slots may be configured within the cell housing to define at least one fluid flow channel extending substantially in a first direction through the cell housing. The fluid flow channel may be defined at least partially by a rib connecting at least two adjacent cell reception slots to enable thermal transfer from cells disposed in the at least two adjacent cell reception slots responsive to movement of a fluid through the fluid flow channel and to inhibit a crossflow of fluid between the at least two adjacent cell reception slots in a direction other than the first direction.

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.
