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. Partin, Richard V. Chamberlain, II, Jan-Roger B. Linna, Mimmo Elia

Patent number: 8012615Abstract: 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. 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. More preferably, the first conductive plate includes 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. More preferably, the second conductive plate is in electrical contact with the essentially planar cap through a weld. A battery, preferably a lithium-ion battery, comprises a CID as described above.Type: GrantFiled: October 12, 2010Date of Patent: September 6, 2011Assignee: Boston-Power, Inc.Inventors: Per Onnerud, Phillip E.
