  • System and method for monitoring battery state
    Patent number: 7573237
    Abstract: A method of monitoring a battery includes measuring an open circuit voltage (Voc) on the battery to determine a measured state of charge (SOCm) after at least one use, obtaining a calculated state of charge (SOCc) based on a state of charge prior to the at least one use and a discharge of the battery during the at least one use, and determining a state of the battery based at least in part on a difference between the calculated state of charge and the measured state of charge.

  • Mobile power supply
    Patent number: 7531917
    Abstract: A power supply system suitable for use in a mobile cart for providing power to peripheral devices. The power supply system includes a combination inverter and transformer connected between an AC input and a battery terminal for providing electrical current to peripheral devices. A charger is connected between the AC input and the battery terminal for charging a battery and a cooling device is located for removing heat from both the combination inverter and transformer and the charger.
