摘要： A battery module 12 for a battery pack (10, figure 1) comprises a cooling (or heating) member 31, preferably a plate with ports 34a,b for inlet and outlet of a cooling fluid, having opposing first 32 and second 33 faces, and a first plurality of cell groups 13a,c mounted on the first face and a second plurality of cell groups 13b,d mounted on the second face of the cooling member, each cell group having a plurality of battery cells (14, figure 4). Each cell group 13a-d is electrically isolated within the battery module from at least one other cell group; preferably all cell groups within a respective module are electrically isolated from each other. A battery pack comprising a plurality of these battery modules is also claimed (figures 1, 2 and 7). Preferably, corresponding cell groups in each module are connected to adjacent cell groups in adjacent battery modules when the battery pack is assembled using connection tabs 41, 42 (figure 8). Channels 16, 17 between cell groups may be provided in the battery modules, which form longitudinal channels in the battery pack for accommodating coolant supply conduits or electrical components (e.g. BMS, distribution system).

摘要： A battery pack 1 has a plurality of battery modules (2a-h, figure 3) in a row along the battery pack. First and second ends of each module comprises terminals (4a-h, 5a-h, figure 3) on first and second sides of the row of modules. The modules are connected together by busbars 6a-e, 7a-e to provide a current flow path through the battery pack. The busbars comprise first busbars 6a-e connecting terminals of respective modules on the first side of the row of modules, and second busbars 7a-e connecting terminals of respective modules on the second side of the row of modules. The battery pack comprises battery management circuitry 16, preferably comprising a wiring harness, disposed along the row of modules in a region between the first and second busbars. The battery management circuitry may be used to connect a battery pack control circuit 13 to sensors 17a, 17b. The location of the battery management circuitry reduces interference from the busbars. Preferably, the battery pack comprises a further row of battery modules (2i-p, figure 3) connected to each other and the first row of modules by third and fourth busbars 8a-e, 9a-e. The battery pack is used in an electric vehicle.

摘要： A battery pack (10, figure 1) comprises a thermal management (cooling) assembly 30 and a plurality of battery modules (12a-h, figure 1). Each battery module has a cooling member 31 with a plurality of cell groups (13a-d, figure 3) mounted thereon, and each cell group has a plurality of battery cells (14, figure 4). The cooling assembly has a common supply conduit 36a and a common return conduit 36b for carrying fluid, a plurality of ancillary supply conduits 35a, and a plurality of ancillary return conduits 35b. Each ancillary supply and return conduit fluidically couples the common supply and return conduits to fluid inlet and outlets (34a-b, figure 3) of the cooling member of a respective battery module. This arrangement enables even thermal management throughout the battery pack. Preferably, channels (16, 17, figure 3) are provided in each battery module, these being aligned in the battery pack to provide longitudinal channels (18, 19, figure 7) which can accommodate the common supply and return conduits and the ancillary supply and return conduits. Cell groups are preferably provided on opposing faces of the cooling member for improved cooling and space efficiency.

摘要： A battery pack (10, figure 1) comprises a plurality of battery cells arranged as first, second, third and fourth laminar arrangements 20a-d of cell groups (13a-d, figure 3). The second laminar arrangement 20b is in a stacked configuration with respect to the first laminar arrangement 20a, and the fourth laminar arrangement is in a stacked configuration with respect to the third laminar arrangement 20c. Cell groups in each of the laminar arrangements are electrically connected to define respective aggregate current paths 61a-d. The laminar arrangements of cell groups are electrically connected such that current in the first aggregate current path 61a flows in the same direction to that in the fourth aggregate current path 61d and in an opposite direction to that in the second and third aggregate current paths 61b,c. This arrangement enables a region (69, figure 9) between the flow paths with a reduced magnetic field, due to the different magnetic fields 68a-d counteracting each other. This region may be utilised as channels 18, 19 between rows of cell groups to dispose sensitive circuitry such as a BMS without magnetic interference. The battery pack preferably comprises a plurality of interconnected modules incorporating stacked and spaced cell groups.

摘要： A battery pack 1 has a plurality of battery modules 2a-h disposed in a row from front to rear of the battery pack, and configured such that current flows along a path from the front to the rear of the battery pack through a first subgroup of the modules 2c-d, 2g-h, and from the rear to the front of the battery pack through a second subgroup of the modules 2f-e, 2b-a. At least one module of the second sub-group 2e-f is located between at least two modules of the first sub-group 2d, 2g. Preferably, the modules are arranged as pairs of adjacent modules, the modules of each pair being directly connected together in series. The first and second subgroups may be connected by a current interruption arrangement such as a fuse 10a and/or switch 14a at the rear of the battery pack. Preferably, the battery pack comprises a further row of battery modules 2i-p arranged in similar subgroups to enable current flow in the battery pack in the same way as the first row. The row and further row may be connected in series or parallel. The battery pack is used in an electric vehicle.
