Abstract:
There is disclosed a battery system comprising a battery pack. Within the battery pack is a plurality of cells, which are electrically connected by physical contact between electrical terminals of adjacent cells. A resistive heater is attached to at least some of the electrical terminals in the battery pack to thereby warm the cells to a more optimum operating temperature in response to a sensed temperature.

Abstract:
The present disclosure discloses a current fuse device. The current fuse device comprises: an insulating box having a cavity; a first conductor fixed to the insulating box with a first outer end and a first inner end; a second conductor fixed to the insulating box with a second outer end and a second inner end; and at least one elastic member disposed on at least one of the first conductor and the second conductor and inside the cavity. The elastic member forms an electrical connection between the first inner end of the first conductor and the second inner end of the second conductor. The elastic member has an elastic potential energy to break the electrical connection when a short circuit occurs.
Abstract:
An electrochemical storage cell is disclosed that comprises a cathode sheet, an anode sheet, and a separator sheet between the cathode and anode sheets. A metal foil current collector extends from a longitudinal edge of the cathode sheet. A further metal foil current collector extends from a longitudinal edge of the anode sheet. The anode sheet, cathode sheet, and separator sheet are wound in a flattened coil shape to produce a core in which the metal foil current collector of the cathode sheet extends beyond the separator sheet at one end of the core and the metal current collector of the anode sheet extends beyond the separator sheet at an opposite end of the core. Overlying layers of the metal foil current collector of the cathode sheet are compressed together and placed in electrical communication with a positive terminal of the cell while overlying layers of the metal foil current collector of the anode sheet are compressed together and placed in electrical communication a negative terminal of the cell.
Abstract:
A battery system having interconnected battery packs is disclosed. Each battery pack includes a plurality of rectangular prismatic shaped cells. Each cell includes a positive terminal at one end and a negative terminal at the other end. The cells are housed in a battery pack housing in a side-by-side manner. The cells may be electrically connected in series so that the positive terminal for a cell extends toward and contacts the negative terminal of an adjacent cell and the negative terminal for the cell extends toward and contacts the positive terminal of another adjacent cell.
Abstract:
A battery system for storing electrical power and supplying electrical power to a vehicle is disclosed. The system includes multiple battery packs, each with a plurality of cells. The cells in each battery pack are electrically connected with one another and the multiple battery packs are also electrically connected with one another to combine the total energy output of the cells of the system. The electrical connections between at least some of the cells include a severable feature, whereby the electrical connection is severed locally at the severable feature in response to an impact force that is in excess of a predetermined magnitude and/or an overcurrent/overtemperature condition.
Abstract:
An electrochemical storage cell is disclosed that comprises a core and a rectangular shell that receives the core snugly therein. The rectangular shell has first and second open ends. A first end cap is used to close the first open end. An anode terminal extends through the first end cap from an interior portion of the electrochemical storage cell to an external portion thereof. A first gasket is secured within the rectangular shell between the first end cap and the core to resiliently hold the core away from the first end cap. A second end cap is used to close the second open end. A cathode terminal extends through the second end cap from an interior portion of the electrochemical storage cell to an external portion thereof. A second gasket is secured within the rectangular shell between the second end cap and the core to resiliently hold the core away from the second end cap.
