    摘要: An apparatus balances a discharge in parallel battery configuration by having a battery pack (a) with a first battery system and a second battery system in parallel configuration, and a pulse width modulation device and (b) being interconnectable to a load. Each of the first and second battery systems has, in series and in order, a first voltage sensor, a resistor, a second voltage sensor, a string of battery cells, and a switching device. The first and second voltage sensor, in each battery system, measures an electrical current, used to calculate the voltage drop across each resistor. The voltage drop values for each battery system determine whether the pulse width modulation device alters or maintains the pulse width modulation applied to each battery system's switching device. By maintaining or altering the pulse width modulation applied to each switching device, the apparatus effectively balances the electrical current discharge from each battery system.

    摘要: Various embodiments of modular battery authentication circuits are described. The various modular battery authentication circuits are intended to be utilized with electrically powered devices that do not comprise existing battery authentication capabilities. In one embodiment, a modular battery authentication adapter is described. The adapter comprises a housing in which a modular battery authentication circuit resides. One end of the adapter is positioned within a power input port of a device and a modular battery is positioned within the opposing end of the adapter. The authentication circuit within the adapter communicates with the modular battery to determine its authenticity before allowing the battery to power the device. A modular battery comprising an internal authentication circuit is also described. The modular battery is designed to interact with firmware stored within the device to determine whether the modular battery meets certain operational criteria.

    摘要: A modular battery pack comprised of multiple modular batteries arranged in series, in parallel, or in series-parallel combinations is described. Each of the modular batteries is comprised of a first pair of opposed keyed side walls for series connection between adjacent modular batteries, and a second pair of opposed keyed side walls for parallel connection between adjacent modular batteries. The modular batteries are only able to connect to each other when the keys are matched and aligned. Additionally, the opposed end walls of the modular batteries have specifically configured terminals that prevent the possibility of making undesired connections between adjacent modular batteries.

    摘要: The present invention relates to an electrochemical cell comprising an anode of a Group IA metal and a cathode of a composite material prepared from a first active cathode material of a transition metal phosphate mixed or added to a second active cathode material of a carbonaceous material. The cathode material of the present invention provides increased rate pulse performance compared to carbon monofluoride cathode material. In addition, the cathode material of the present invention is chemically stable which makes it particularly useful for applications that require increased rate capability in extreme environmental conditions such as those found in oil and gas exploration.

    摘要: A voltage activated 2nd level safety circuit for permanent isolation having a current activated fuse useful for class III medical devices, military applications, and any other passive loads. The battery system has a fuse current limiter and the current activated fuse maintain the fuse closed when a power cell, having a current sufficient to blow the fuse expeditiously, directs its current to the load. The power cell continues to direct its current to the load until the system detects an unacceptable battery or circuit condition. Once that unacceptable condition exists and is detected, a fuse blowing circuitry allows the power cell's current to expeditiously blow the current activated fuse. In response to the blown current activated fuse, the system's isolation switch(es) open as well to establish a permanent isolated battery.

    摘要: A battery powered wireless fluid pressure sensor has a sealed chamber which can be vented to the outside atmosphere through a re-sealable reference port to allow a user to set the reference atmosphere inside the pressure sensor enabling the pressure sensor to provide absolute, gauge and true gauge pressure readings. The sensor calculates and transmits the fluid pressure taking into account the temperature of the pressure transducer, the temperature of the electronic devices and the barometric pressure inside the sealed chamber to provide accurate pressure measurements over a wide range of operating conditions.
