Abstract: A battery comprising a plurality of battery modules arranged in a row, each battery module comprising a plurality of cells and a housing enclosing the plurality of cells. The battery further comprising a supply coolant conduit and a drain coolant conduit, each adjoining and extending along at least part of the row of battery modules, the supply coolant conduit being configured to supply coolant to multiple ones of the battery modules and the drain coolant conduit being configured to drain coolant from multiple ones of the battery modules.

Abstract: A battery module comprising a housing defining an internal cell cavity and cells located in the cell cavity. The housing comprises two substantially parallel walls and an end structure extending between the two walls, the end structure defining an end of the housing in a first direction, the end structure being inclined with respect to the top and bottom walls such that the cell cavity extends in the first direction beyond the furthest extent of the top wall, and being configured such that the battery module can nest with asimilar battery module.

Abstract: A battery compartment for holding a plurality of cells, the battery compartment comprising a housing defining a chamber in which the plurality of cells are to be located, a cell tray for supporting the plurality of cells within the chamber and a plurality of openings in a wall of the housing, each opening allowing the passage of electrical cabling through the wall and also coolant flow into or out of the chamber.

Abstract: A battery module comprising a cell tray defining a plurality of cell holes for holding cells and a fixing hole for securing the battery module to a vehicle. The battery module further comprising a plurality of cells in the cell holes and a housing enclosing the cells, wherein the fixing hole is accessible outside the region enclosed by the housing.

Abstract: A battery comprising a battery housing, a lid for closing the housing and defining therein a chamber; and a plurality of battery modules within the chamber, each module having a plurality of battery cells, and a longitudinal cell tray for supporting the plurality of cells, wherein the cells of the battery modules are open to the chamber.

Abstract: A battery cell tray comprising a main body having a plurality of holes extending therethrough from a first face to a second face, a plurality of battery cells, each cell retained in a respective hole of the main body, wherein each cell protrudes out of the main body on both the first and the second faces.

Abstract: A method of cooling an array of battery cells within a chamber in a housing, the battery cells being electrically connected via a busbar having at least one terminal tab for connection to an electrical terminal in the housing, the method comprising the steps of: supplying coolant through an opening in the housing into the chamber; and diverting at least a part of the coolant flow from its inlet flow path due to impingement of the flow upon part of the terminal tab.

Abstract: A method for assembling a battery module, the method comprising: providing a cell tray defining a plurality of cell holes for holding cells; inserting cells into respective cell holes so that the cells each protrude from the cell tray at each end of the cell; attaching a first casing to a first side of the cell tray to enclose the cell ends protruding from the first side; and attaching a second casing to a second side of the cell tray to enclose the cell ends protruding from the second side.
