Integral Battery Power Limiting Circuit for Intrinsically Safe Applications

Detailed Technology Description: NASA Kennedy Space Center (KSC) invites companies to license this innovative power-limiting circuit for batteries.

*Abstract: NASA Kennedy Space Center (KSC) invites companies to license this innovative power-limiting circuit for batteries. This technology is designed to limit the power output from a battery without compromising battery lifetime in situations where there is little headroom for dropping voltage or wasting current. The invention was developed to ensure that the full power of the battery will not be available in the event of a short circuit, cut in a cable, or similar event. This technology prevents a spark emitted from a battery during a short circuit from possibly igniting volatile chemicals, while not drawing much additional power in the process. The device can shut off a circuit within 55 µs, 20 times faster than the fastest rated fuse.
