BATTERY MODULE, AND BATTERY PACK AND VEHICLE COMPRISING SAME
A battery module including: three cell stacks where each of the three cell stacks includes a plurality of battery cells; a cell tray including a base plate on which the three cell stacks are seated, and three split plates disposed upright on the base plate to partition a space so that the three cell stacks may be disposed in spaces separated from each other; a housing for the three cell stacks and the cell tray, where the housing has a hexagonal pillar shape; and a bus bar frame assembly configured to cover an opening formed in an upper portion of the housing, where the bus bar frame assembly electrically connects the plurality of battery cells.
Systems and methods for monitoring and responding to forces influencing a battery
Systems and methods for monitoring and responding to forces influencing batteries of electronic devices are provided. One or more sensors may be provided at various positions within a battery assembly including one or more battery cells within an enclosure. In some embodiments, a sensor may be provided between a battery cell and a portion of the enclosure. In other embodiments, a sensor may be positioned between two adjacent cells in a stack. Each sensor may detect a force influencing a battery cell of the assembly. In some embodiments, the sensor may be a force sensing material having a conductance configured to vary based on the influencing force. In other embodiments, the sensor may be a contact sensor that detects when the influencing force moves two elements together.
Passive thermal management system for battery
A battery includes a thermally conductive housing, a first battery cell enclosed within the thermally conductive housing, and a laminated element enclosed within the thermal conductive housing. The laminated element is in contact with the first battery cell and the thermally conductive housing. The laminated element includes one or more heat conducting layers and one or more intumescent layers. The laminated element is configured to conduct heat generated by the first battery cell from the first battery cell to the thermally conductive housing during normal operational conditions of the first battery cell. A local portion of the laminated element adjacent to where the laminated element contacts the first battery cell is configured to reconfigure into a non-heat conducting configuration when the first battery cell experiences a thermal runaway condition.
Methods and systems for providing backup power
Methods and systems for providing battery backup power to a home or other building are disclosed. Methods and systems include a fluid container holding an electrolyte solution. The electrolyte solution is prevented from flowing through an array of galvanic cells having annular flow paths via a fluid flow control mechanism, such as a valve, which is energized by an external power source. When the external power source is removed, such as during a power outage, the fluid flow control mechanism is deenergized and electrolyte solution is allowed to flow through the galvanic cell array, generating electric current. Energy produced by the system then powers the home or other building until the external power source returns, which in turn closes the fluid flow control mechanism and ceases energy production by the system.
