  • Method and apparatus for high-voltage battery array monitoring sensors network
    Patent number: 6677759
    Abstract: A battery-monitoring system in accordance with the principles of the present invention includes one or more cell sensors modules linked to a battery sensor module via a data interface. In turn, the one or more battery sensor modules may be linked to an alarm interface. Each cell sensor module includes one or more sensors that monitor physical parameters, such as cell voltage and temperature, related to the corresponding cell. Each battery sensor module monitors physical parameters, such as battery voltage, discharge current, and temperature related to the battery. The battery sensor module also gather cell monitoring information from the plurality of cell sensor modules. Various battery monitor-related analytical, control, and reporting functions may be performed by the various modules.

  • Smart battery system with an A/D converter that converts both positive and negative analog input signals
    Patent number: 5789899
    Abstract: A battery pack and a method of operating a battery system. The battery pack includes a rechargeable battery, an analog-to digital converter, and a processor. The analog-to digital converter is able to convert both positive and negative analog signals to digital signals; and, in use, the converter receives analog signals representing battery voltage, battery temperature, and battery current, and converts those signals to digital signals. The processor receives those digital signals from the converter and uses those digital signals to perform a series of calculations.
