  • Patent number: 10283974
    Abstract: Systems and methods for intelligent, adaptive management of energy storage packs are disclosed. A method comprises receiving a first current measurement of a first energy storage cell electrically connected to a first converter circuit. The first converter circuit controls the charge and discharge of the first energy storage cell. A first voltage measurement of the first energy storage cell is received. A first temperature measurement of the first energy storage cell is received. The first current measurement, the first voltage measurement, and the first temperature measurement are translated into a state of charge of the first energy storage cell.

  • Patent number: 9397502
    Abstract: A system and method for proportioned power distribution in arrays of power converters are disclosed. According to one embodiment, a method includes distributing a node-specific transfer function to each node of a plurality of nodes via a communication bus. Each node includes a power converter, and nodes of the plurality of nodes are electrically connected in series. Each node-specific transfer function enables each node to contribute a positive impedance to a total impedance of the plurality of nodes. The computer-implemented method further includes coordinating a setting of a parameter of each node-specific transfer function to regulate a common bus current across the plurality of nodes, and assigning to each node an electrical characteristic based on a parameter of each node-specific transfer function.

  • Patent number: 8686693
    Abstract: A system and method for scalable configuration of intelligent energy storage packs are disclosed. According to one embodiment, a method comprises providing a first current measurement of a first energy storage cell electrically connected to a first converter circuit, and the first converter circuit controls the charge and discharge of the first energy storage cell. A first voltage measurement of the first energy storage cell is provided. First control signals are received and the first control signals are determined according to a load policy. The first converter circuit transforms a first voltage from the first energy storage cell to a desired first bus contribution voltage according to the first control signals.
