摘要： 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.

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. A method of manufacturing such a CID comprises forming first and second conductive plates as described above, and welding the second conductive plate onto the first conductive plate while a temperature of the first conductive plate is controlled so as not to exceed the melting point of a surface of the first conductive plate opposite the weld.

摘要： 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. The control electronics are either implemented into the electronic device or the battery pack, or in a separate control electronic device.
