  • Patent number: 9553470
    Abstract: The invention relates to a method of operating a lead acid battery which undergoes discharging phases and charging phases in a cyclical fashion. The method involves monitoring the current discharged from the battery during a discharging phase and recording information relating to that current flow, such as the charge lost from the battery. During the subsequent charging phase, a desired amount of charge to be supplied to the battery is calculated based upon the recorded information, and then supplied to the battery.

  • Patent number: 9479003
    Abstract: A power control device has a voltage-regulator from power source to load, the load configurable to receive power at least at a first or second rate. The device has monitor circuitry to measure power; signal circuitry for signaling a power-reception rate to the load; and circuitry for resetting the load when the power source is overloaded. The device resets the load periodically to the second rate when the load is at the first rate. In embodiments, the power source is a thermoelectric generator or solar panel. In embodiments, the load couples through a USB connector. A companion method of charging smart loads includes applying power to the load; communicating power available to the load; configuring a battery charger in the load to absorb an amount of power less than that available; monitoring power, determining when changed configuration may optimize charging time of a smart load battery; and resetting the smart load to optimize current.
