A battery mounting structure of an electric vehicle is provided. The battery mounting structure includes a battery case including a side case portion in which a recess portion concave inwardly is formed and a battery connection member mounted in a vehicle body and having an insert portion inserted into the recess portion and connected to the side case portion.

An embodiment battery-mounting structure includes a side sill, a mounting bracket connected to the side sill, the mounting bracket being deformable by external force, a connecting member coupled to the mounting bracket and spaced apart from the side sill by a predetermined distance, and a battery assembly including a side flange coupled to the connecting member, the battery assembly being configured to receive a high-voltage battery.

The invention relates to a system for installation of traction batteries for a vehicle having a chassis comprising at least one load-carrying frame member. A front bracket member and a rear bracket member are adapted to be secured to and project from the frame member of the vehicle for receiving a traction battery between the front bracket member and the rear bracket member. The system also comprises a first and a second slider adapted to be connected to a front and a rear side, respectively, of a traction battery. The sliders are adapted to be mated with the bracket members subsequently to the sliders having been connected to the traction battery, thereby enabling the traction battery by means of the connected sliders to be received by the bracket members and be moved towards the frame member of the vehicle.

An embodiment is directed to a module-to-module power connector configured to form connections between battery modules installed in a battery housing of an energy storage system. The module-to-module power connector includes electrical interfaces and busbar(s) configured to form one or more electrical connections terminals of adjacent battery modules. The busbar(s) is flexibly configured to permit a defined range of movement of the electrical interfaces during insertion of the respective battery modules into respective battery module compartments. The module-to-module power connector may further be arranged inside in a tunnel space, whereby holes are defined in a battery module mounting area housing the battery modules that open into the tunnel space.

A fastening arrangement for attaching a battery pack to a vehicle frame of a vehicle. The fastening arrangement comprises one or more main brackets arranged attachable to the vehicle frame, each main bracket comprising a receiving member arranged to hangably support a corresponding mounting element. The fastening arrangement also comprises one or more of the mounting elements configured attachable to the battery pack. The fastening arrangement further comprises one or more mounting straps arranged to press the battery pack against the one or more main brackets.

Embodiments are directed to contact plates configured to establish electrical bonds between battery cells in a battery module. In a first embodiment, the contact plate includes at least one primary conductive layer including a hole that is aligned with two or more terminals of two or more battery cells in a group of battery cells that are configured to be connected in parallel with each other, and a bonding connector configured to provide direct electrical bonds between the contact plate and the two or more terminals of the two or more battery cells. In a second embodiment, a contact plate includes at least one primary conductive layer and a set of bonding connectors made from at least one material that is selected to match at least one material used for the terminals of the at least one group of battery cells.

The present disclosure relates to energy storage mounting system for an energy storage system of a vehicle, the mounting system comprising: a vehicle mounting member connectable to a longitudinal frame of the vehicle, the vehicle mounting member comprising an elongated portion arranged to, when the vehicle mounting member is attached to the longitudinal frame, extend away from the longitudinal frame, wherein the elongated portion comprises a recess at an outer end portion thereof; and a battery mounting member connectable to the energy storage system, the battery mounting member comprising a connecting portion, wherein the connecting portion is movable between a disconnected state, in which the connecting portion is positioned at a distance from the elongated portion of the vehicle mounting member, and a connected state, in which the connecting portion is positioned in the recess for connecting the battery mounting member to the vehicle mounting member.

The present disclosure relates to a battery module support arrangement for supporting a battery module to a longitudinally extending frame rail of an electrified heavy vehicle; the battery module support arrangement comprising a pair of triangularly shaped support brackets spaced apart from each other, each of the triangularly shaped support brackets comprising a rail attachment portion for connecting the triangularly shaped support bracket to the longitudinally extending frame rail, and an angled portion extending downwardly between the rail attachment portion and a lower end portion of the triangularly shaped support bracket, wherein a first one of the triangularly shaped support brackets comprises at least one battery module support portion positioned along the angled portion of the first support bracket, and a second one of the triangularly shaped support brackets comprises a pair of battery module support portions positioned along the angled portion of the second support bracket, wherein the battery module support portion of first support bracket is arranged at a different position along the angled portion compared to the position of the battery module support portions of the second support bracket.

In an embodiment, a clamping bar holder component configured to be secured to an endplate of a battery module includes a plurality of clamping bar holders configured to hold a respective plurality of clamping bars and to facilitate transitions of each of the plurality of clamping bars between a parked state and an unparked state. In the parked state, each clamping bar is secured by a respective clamping bar holder inside of a respective clearance threshold so as to permit the battery module to be inserted into a battery module compartment and/or to be removed from the battery module compartment. In the unparked state, each clamping bar extends out of the clamping bar holder past the clearance threshold so as to block removal of the battery module from the battery module compartment.

An electric car provided with a battery compartment, said electric car comprising a car body (17), a chassis (19), a power drive system, a cab (16) and a control system, the power drive system comprising a battery compartment (8), the battery compartment (8) being fixed at a lower portion of the chassis (19), the battery compartment (8) being a rectangular cavity body wherein one end is a battery inlet/outlet (8.1) and the inner side of the other end is provided with a battery connection socket (14), the rectangular cavity body being internally provided with a battery automatic push-out/guide-in apparatus, the battery inlet/outlet (8.1) of the battery compartment (8) facing towards the front, the rear or the side of the electric car, the control system controlling the battery automatic push-out/guide-in apparatus inside the battery compartment (8) to move. The battery compartment can automatically push out a battery therein, and can also automatically guide in a battery, to facilitate rapid swapping with a battery of a charging device, and increase battery loading/unloading efficiency.
