  • Hybrid battery power system
    Patent number: 9214710
    Abstract: A hybrid battery is configured to power at least one of a low current circuitry and a high current circuitry. The hybrid battery includes a primary battery configured to supply relatively constant, low current to the low current circuitry and a secondary battery configured to supply intermittent, high peak current to the high current circuitry. The hybrid battery also includes a controller configured to monitor energy load requirements of the low current circuitry and the high current circuitry, adaptively direct energy generated by the primary battery and the secondary battery to the low current circuitry and the high current circuitry respectively, and maintain a state of charge of the secondary battery by directing electrical energy from the primary battery to the secondary battery.
