  • Power source with temperature sensing
    Patent number: 8324868
    Abstract: A modular and scalable power source can be used to supplement and/or replace existing sources of power. In some embodiments, a DC source can be used to charge a battery in a host system, provide power as a back-up system, or be a primary source of power. The power source includes a set of battery units and one or more circuits that provide an alternative signal path around the battery units if the battery units are at a particular charge level. Temperature sensors are used to turn off or otherwise adjust the alternative signal paths if the temperatures of the alternative signal paths become too high.
    Type: Grant
