Patent number: 7838143Abstract: 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: June 19, 2008Date of Patent: November 23, 2010Assignee: Boston-Power, Inc.Inventors: Per Onnerud, Phillip E. Partin, Richard V. Chamberlain, II, Jan-Roger B. Linna, Mimmo Elia

Publication number: 20100289457Abstract: A method of providing power to an electronic device in an energy-efficient manner includes transitioning between power states corresponding to charging and discharging a battery. The state of charge of the battery is detected. Upon detecting a high threshold state of charge, an external power source such as an AC-to-DC adapter is disabled, and the battery to provides primary power to the electronic device. Upon a low threshold state of charge, the AC-to-DC adapter is controlled to provide a high current output to charge the battery and provide primary power to the electronic device. The power states, when cycled over time based on the state of the battery, provide for an energy-efficient method of powering the electronic device.Type: ApplicationFiled: May 17, 2010Publication date: November 18, 2010Applicant: Boston-Power, Inc.Inventors: Per Onnerud, Phillip E.

Patent number: 7811708Abstract: A lithium-ion battery includes a cathode that includes an active cathode material. The active cathode material includes a cathode mixture that includes a lithium cobaltate and a manganate spinel a manganate spinel represented by an empirical formula of Li(1+x1)(Mn1-y1A?y2)2-x2Oz1 or Li(1+x1)Mn2Oz1. The lithium cobaltate and the manganate spinel are in a weight ratio of lithium cobaltate:manganate spinel between about 0.9:0.1 to about 0.6:0.4. A lithium-ion battery pack employs a cathode that includes an active cathode material as described above. A method of forming a lithium-ion battery includes the steps of forming an active cathode material as described above; forming a cathode electrode with the active cathode material; and forming an anode electrode in electrical contact with the cathode via an electrolyte.Type: GrantFiled: December 22, 2008Date of Patent: October 12, 2010Assignee: Boston-Power, Inc.Inventors: Christina M.

Publication number: 20100164436Abstract: A storage voltage of a battery pack is controlled with control electronics. The storage voltage of a battery pack is sensed, and a discharge mechanism is triggered if the storage voltage is within a predetermined range of voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined range of voltage, or if the storage voltage is at or above a predetermined voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined voltage. Control electronics sense a storage voltage of a battery pack and trigger a discharge mechanism if the storage voltage is within a predetermined range of voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined range of voltage, or if the storage voltage is at or above a predetermined voltage, to thereby adjust the storage voltage of the battery pack to below the predetermined voltage. The control electronics are coupled to an electronic device and a battery pack.Type: ApplicationFiled: December 31, 2009Publication date: July 1, 2010Applicant: Boston-Power, Inc.Inventors: Christina M.

Publication number: 20100121511Abstract: A large battery array, particularly for use in an electric vehicle, is formed of multiple modules, each containing plural battery cells and module management electronics. Each battery module has a nominal output voltage in the range of about 5 volts to about 17 volts. A controller communicates with individual battery modules in the array and controls switching to connect the modules in drive and charging configurations. The module management electronics monitor conditions of each battery module, including the cells it contains, and communicates these conditions to the controller. The module management electronics may place the modules in protective modes based upon the performance of each module in comparison to known or configurable specifications. The modules may be pluggable devices so that each module may be replaced if the module is in a permanent shutdown protective mode or if a non-optimal serviceable fault is detected.Type: ApplicationFiled: October 6, 2009Publication date: May 13, 2010Applicant: Boston-Power, Inc.Inventors: Per Onnerud, Scott D.
