Patent: Is Crestron Building a Smart Back-up Power Generator?
Crestron patent application describes a smart back-up generator that prioritizes loads for both the initial power outage and longer-term outages.
The application describes:
a backup power system that selectively provides power to particular circuits according to a power distribution priority profile, where power is applied sequentially to each particular circuit depending on the measured current loads of the particular circuits to which power has already been applied.
The patent application notes some of the deficiencies of typical back-up generation schemes – often, the products power an entire circuit box, including non-essential loads, so precious power is wasted.
Either that, or loads are shed manually in the case of a power outage.
Alternatively, some facilities power all essential loads via a single breaker box attached to a generator, but this limits the flexibility of the system.
In the Crestron patent application, all the circuits are computer-controlled, so when the needs of the facility change, it’s simple to reset priorities.
In one scenario, Crestron suggests:
Further, such backup power systems are not capable of providing power to circuits and devices that are initially essential (e.g., elevators containing people) and shedding those circuits and devices when they become non-essential after a short time (e.g., elevators after all the people have exited). Moreover, such backup power systems are not capable of prioritizing the circuits and devices to which power is supplied, i.e., provide power to the most critical circuits first, then to the less critical circuits if power is available. Current backup power systems simply supply power to the circuits to which they are connected, and individual devices must be shed manually. Moreover, the circuits and devices that are powered by such backup systems are predetermined and unalterable, and cannot be adjusted based on some event.
