  • Battery management system
    Patent number: 10404098
    Abstract: A battery management system for monitoring battery cells of an uninterruptible power supply (UPS) coupled to a medical imaging load. The battery management system includes a first slave configured to obtain an operating parameter of a first battery cell. The first slave is configured to determine health of the first battery cell based at least in part on the operating parameter. The first slave is configured to generate a signal indicating the health of the first battery cell to communicate serially, via at least a second slave, to a master.
    Type: Grant

  • Uninterruptible power supply (UPS) direct current (DC) load leveling
    Patent number: 10116163
    Abstract: A system includes an AC-DC converter configured to convert power from an AC supply to a DC bus to provide a first portion of power a medical imaging load. The system includes an uninterruptible power supply (UPS) coupled to the DC bus. The UPS comprises at least one battery cell and a DC-DC converter comprising one or more switches and coupled between the at least one battery cell and the DC bus. The system includes a control system comprising a processor configured to send one or more signals to control operation of the one or more switches to cause the DC-DC converter to control power discharged from the at least one battery cell to the DC bus to provide a second portion of power to the medical imaging load.
