Abstract: A battery module includes a housing, assembled from a first side wall, a second side wall, a first end plate, and a second end plate, is configured to support a plurality of battery cells. The battery module also includes a heating pad and a cooling plate that are configured to regulate a thermal state of the plurality of battery cell. The heating pad is disposed substantially adjacent to the plurality of battery cells and the cooling plate is disposed adjacent to the heating pad opposite the plurality of battery cells. A controller associated with the battery module is configured receive an indication of battery temperature and active one of the heating pad or the cooling plate based at least on the battery temperature of the plurality of battery cells.

Abstract: A battery module includes a housing, battery cells disposed within the housing, and a wedge apparatus disposed within the housing and configured to exert a substantially constant force on the battery cells. The wedge apparatus includes a first wedge having a first thick end tapering to a first thin end, and a second wedge having a second thick end tapering to a second thin end, the first wedge and the second wedge positioned such that the first wedge and the second wedge at least partially overlap. The wedge apparatus further includes a tensioning mechanism disposed at least partially in the first opening and the second opening and configured to move the first wedge in a first direction relative to the second wedge causing a width of the wedge apparatus to expand and exert a first force on the plurality of battery cells.

Abstract: A battery module for construction of a battery pack includes a battery sealed in a rectangular housing with front and rear open ends closed by front and rear plates, respectively. The rear plate includes a plurality of rear plate bores in axial alignment with a plurality of housing bores proximal the rear open end of the housing. The front plate includes a plurality of front plate bores in axial alignment with a plurality of housing bores proximal the front open end of the housing. The front plate additionally includes positive and negative terminals electrically connected to the battery. At least one of the rear plate and the front plate further includes at least one inactive opening, and at least one of a grounding cable, a clipping structure adapted to receive a cable, or a supplemental, non-conductive attachment is received by the inactive opening.

Abstract: An example system includes a base having a surface and a post coupled to the base and extending in a first direction that is transverse to the surface of the base. The system further includes a battery module having a housing supported by the base and defining an internal space, the housing being configured to secure one or more battery cells within the internal space. The housing of the battery module includes an end plate extending in the first direction, and a receiver formed in the end plate and defining a hollow portion in the end plate, wherein the post extends at least partly within the receiver and is coupled to the receiver.

Abstract: In some aspects, a method of monitoring a battery system of an industrial vehicle is disclosed. The battery system may include a first string of battery modules including at least two battery modules connected in series; a first contactor connected to a positive end of the first string of battery modules, a second contactor connector to a negative end of the first string of battery modules; a third contactor connected to the first contactor; a fourth contactor connected to the second contactor; and one or more controllers configured to monitor the first contactor and the second contactor. The method may include receiving, at the one or more controllers, an indication of a failure of one of the first contactor and the second contactor; and opening, via the one or more controllers, at least one of the third contactor or the fourth contactor.
