Abstract: Provided in this disclosure is a passive internal cooling system for a battery pack. First and second stacking frames are provided, each having mating structures for engaging and retaining the first and second stacking frames to each other. Each of the first and second stacking frames are configured for substantially surrounding and enclosing a surface of a battery module for retaining one or more batteries. One or more TRS pouches are enclosed between the first and second stacking frames. The TRS pouch(es) includes a thermally cooling fluid that ruptures into the battery module from heat produced in a thermal runaway event in the battery module.

Abstract: Provided in this disclosure is a battery pack system including battery modules each including battery cells. An air-tight, sealed enclosure retains the battery modules. A battery manager controls operation of each of the battery modules. One or more thermal runaway shield (TRS) pouches are associated with each of the battery modules. The TRS pouches include a thermally cooling fluid that ruptures into the battery module from heat produced in a thermal runaway event in the battery module. A pressure monitoring sensor detects an increase in air pressure within the sealed enclosure associated with gas released from the thermal runaway event in the battery cells in the battery modules. A communication component transmits a pressure signal from the pressure monitoring sensor to the battery manager for implementing a subsequent management step of the battery pack system.

Abstract: One or more buttons, located either on a battery pack or on an electronic device powered by the battery pack, that allow the user to charge the battery of a portable device faster than normal. Electronic circuitry is provided for activating the charge mode choices.

Abstract: A battery comprises a first terminal in electrical communication with a first electrode of the battery, a second terminal in electrical communication with a second electrode of the battery, a battery can electrically insulated from the first terminal, and at least one current interrupt device in electrical communication with the battery can. The battery can includes a cell casing and a lid which are in electrical communication with each other. At least a portion of the battery can is at least a component of the second terminal, or is electrically connected to the second terminal. The current interrupt device includes a first conductive plate in electrical communication with the second electrode, and a second conductive plate in electrical communication with the first conductive plate.
