  • Smart battery and smart battery systems
    Patent number: 10608295
    Abstract: Smart batteries and smart battery systems are disclosed. A smart battery may include an energy-storage unit providing a cathode tab and an anode tab. The smart battery may also include a circuit integrated with the energy-storage unit. The circuit may be configured to provide electrical connections to the cathode tab and the anode tab of the energy-storage unit to an external device; measure a current, a voltage, a temperature, and/or an internal resistance of the energy-storage unit; control an input/output property of the energy-storage unit; and establish a data connection with the external device.

  • Modular battery network systems and methods for managing modular battery network systems
    Patent number: 10381691
    Abstract: A battery network is disclosed. The battery network may include a plurality of battery blades. Each battery blade may include a plurality of battery cells; a connection mechanism configured to establish an adjustable connection between the plurality of battery cells; and a processor in communication with the connection mechanism and the plurality of battery cells. The processor may be configured to control the connection mechanism at least partially based on a state of charge of at least one of the plurality of battery cells, and the processor of each battery blade of the plurality of battery blades may be further configured to communicate with each other to support operation of the battery network as an integrated electric power source.

  • Distributed power supply system and method
    Patent number: 9502893
    Abstract: A distributed power supply system and a method for managing such a distributed power supply system is disclosure. The method may include: for each power storage unit i of the plurality of power storage units, determining whether power storage unit i have sufficient status of charge (SOC) based on SOC of the power storage unit i (Ci), and load of the power storage unit i (Li); identifying a set of power storage units that have insufficient SOC; and adjusting output power of the power storage units that have sufficient SOC to provide supplemental power to the set of power storage units that have insufficient SOC.
