Patent number: 8679670Abstract: A low pressure current interrupt device (CID) activates at a minimal threshold internal gauge pressure. Preferably, the CID includes a first conductive plate and a second conductive plate in electrical communication with the first conductive plate, the electrical communication between the first and the second conductive plates being interrupted at the minimal threshold internal gauge pressure. The first conductive plate can include a frustum having a first end and a second end, a base extending radially from a perimeter of the first end of the frustum, and an essentially planar cap sealing the second end of the frustum. The first end has a broader diameter than the second end, and the second conductive plate is in electrical contact with the essentially planar cap through a weld.Type: GrantFiled: November 15, 2011Date of Patent: March 25, 2014Assignee: Boston-Power, Inc.Inventors: Per Onnerud, Phillip E.

Patent number: 8642195Abstract: A modular current interrupt device includes an electrically-conductive rupture disc, an electrically-conductive pressure disc attached to the rupture disc to form an electrical pathway. An electrically-insulating ring partitions a perimeter of the rupture disc from a perimeter of the pressure disc, and a seating element secures the electrically-insulated ring to the pressure disc. At least one of the rupture disc and electrically-insulating ring defines a conduit, whereby exposure of one side of the pressure disc to sufficient force through the conduit causes the pressure disc to separate from the rupture disc to thereby sever the electrical pathway. A low pressure current interrupt device (CID) activates at a minimal threshold internal gauge pressure in a range of, for example, between about 4 kg/cm2 and about 9 kg/cm2.Type: GrantFiled: January 28, 2010Date of Patent: February 4, 2014Assignee: Boston-Power, Inc.Inventors: Mimmo Elia, Jan-Roger Linna, Phillip E.

Patent number: 8483886Abstract: The methods in this disclosure allow for the identification, selection, and arrangement of cells, blocks, and modules in large scale battery systems, such as electric vehicle battery systems. An example embodiment of the present invention allows for the identification of the cells, blocks, and modules with a unique identifier or associated parameter (e.g., internal resistance contributions or capacity). Additionally, to form a block, cells may be selected from a group of capacity-range sorting bins. Based on a parameter of the cell, a pseudo-number generator may be also be used to select cells from an available inventory of cells as maintained in a cell database based. Cells may also be placed in a block for uniform effective cell impedance and even cell aging while minimizing overall block capacity degradation caused by cycling. Block capacities may also be computed based on a known average temperature gradient during operation.Type: GrantFiled: August 31, 2010Date of Patent: July 9, 2013Assignee: Boston-Power, Inc.Inventors: Per Onnerud, Jan-Roger Linna, John Warner, Chad Souza, Eckart Jansen
