Abstract: A battery module construction that provides passive resistance to propagation of cell failure, such as thermal runaway. The walls of cells of a battery module may be thermally isolated from each other by securing cells in a frame formed of thermal insulating material, separating the cells from one another, thereby limiting thermal energy from propagating directly between adjacent cells. A vent layer may permit ejection of hot gases and other ejecta into an air gap above the cells, venting the ejecta and dissipating thermal energy. The vent layer may be formed from, e.g., a frangible layer of dielectric gel, or a plastic vent tray with apertures for venting of ejecta and passage of wiring with collectors mounted over the vent tray. A heat sink or cooling module may be thermally coupled to an opposite end of cells to further aid thermal energy removal from the module.

Abstract: A battery assembly includes a thermal shield. The thermal shield protects battery cells in the battery assembly from hot gases vented by a neighboring cell experiencing thermal runaway. The thermal shield acts as a one-way valve, allowing the cell experiencing thermal runaway to properly vent away hot gases, but still protecting the rest of the cells in the battery pack from the hot gases.

Abstract: The embodiments herein describe a feedback system for an electric motorcycle. The feedback system notifies a user of the electric motorcycle of various conditions of the electric motorcycle via one or more output devices. In one embodiment, the feedback system causes the left and right grips of the handlebar of the electric motorcycle to vibrate to communicate information to the rider of the electric motorcycle.
