Abstract: Presented is a system for cooling components of an electric motor vehicle. It utilizes the cold plate, a large metal plate necessary for cooling the batteries and electronics, as a structural member. Instead of being passively contained, the cold plate is used to increase the torsional rigidity of the monocoque. The structural cold plate takes on shear stresses, unlike a passively-contained, non-structural cold plate. The use of the cold plate itself as a stress member negates the need for additional redundant features or structures in the monocoque to resist forces and prevent flexure. Thus the monocoque can be pared down and its weight minimized or larger component accommodated. Cold plates can be made in several ways, from different materials, of varying thickness and shapes.

Abstract: The busbar has a planar portion and multiple blisters that project from it. The blisters have a beam-like structure and provide structural rigidity to the busbar. When the ends of the blisters are connected to the terminals of the cells in the battery, the battery assembly is provided with structural strength. The busbars may be arranged side-by-side or in layers. When in layers, the blisters of the upper busbars project through holes in the lower busbars. Busbar assemblies may include insulating spacers, insulating layers, or venting features. By using the busbar as a structural member, the required strength and weight of the remaining components of the battery pack are reduced.

Abstract: A cell holder made up of a top tray, an intermediate tray and a frame. Cells are placed with minimal force in the frame to stand proud of it. The intermediate tray is placed over the projecting tops of the cells and serves to locate the cells. A busbar in the intermediate tray is connected to one set of terminals. A top tray is placed over the intermediate tray and snap-locked through the intermediate tray to the frame. The snap-lock distance is short. A busbar in the top tray is connected to the other set of terminals. The top tray shields the first busbar. Vents may be included to allow for the escape of hot cell gases in the event of failure.

Abstract: Vented cells are held in a cell holder, which is also vented, to provide an escape path for gases that may be produced by failing or overloaded cells. The escape path leads to the outside of the cell holder, which is mounted in an enclosure forming the battery pack. The enclosure is also vented, via a pressure-relief valve, which allows for the escape of hot cell gases to the surrounding air. A cell holder is made up of a top tray, an intermediate tray and a frame. A venting path is formed between the top and intermediate trays.

Abstract: A locking system is used to safely immobilize electric motorcycles. The system involves a pin-based locking device that can be activated by the user via a key, remote and/or a switch located on the dashboard of the electric motorcycle. The locking device engages the pin with a component that is rotated by the transmission of the electric motorcycle. When activated, the locking device locks the transmission and prevents the motorcycle from being subjected to unwanted driving wheel rotation.

Abstract: A busbar holder with two busbar trays maintains positive and negative busbars separate and insulated from each other to reduce the chance of accidental short circuits. Cells are located in a frame onto which the busbar holder is mounted. One busbar is located in a bottom tray of the busbar holder. Legs of the busbar project down through holes in the bottom tray, for connection to one set of terminals of the cells. A top tray is placed over the bottom tray. Another busbar, in the top tray, is connected through holes in both trays to the other set of terminals of the cells. The busbar in the bottom tray is covered by the top tray. Holes through the busbar holder allow for hot gases to escape in the event of cell failure.

Abstract: A core of the electric motorcycle includes a monocoque that partially encloses a housing for a motor and gearbox. Separate suspension mounts attach to the core, which permits them to be exchanged for other mounts to provide different suspension geometries. A power electronics unit attaches to the front of the monocoque. The shape of the monocoque allows for the proper positioning of the center of gravity of the motorcycle in order to provide a balanced ride.

Abstract: A battery housing includes a battery frame that holds a plurality of battery cells. Each battery cell includes a positive terminal and a conducting structure at one end, a negative terminal at the opposite end, and a conductive shell that electrically couples the negative terminal to the conducting structure. An interconnect creates an electrical connection between two cells by contacting either the conducting structure or the positive terminal of each cell. The cells are positioned so that the positive terminals, conducting structures, and interconnect are all on the same side of the battery frame. As a result, the interconnect can be shorter in length.

Abstract: A battery housing includes a heat spreader, a thermal interface that contacts a surface of the heat spreader, and a battery frame that is configured to hold a plurality of battery cells. When a battery cell is inserted into the battery frame, the thermal interface contacts the cell at the same end as the cell's negative terminal. As a result, the thermal interface allows heat to be transferred between the battery cell and the heat spreader. It is advantageous to make a thermal connection at the end with the negative terminal because the internal jelly roll structure of the battery cell causes the cell to have a higher thermal conductivity at its negative terminal.
