According to aspects of the disclosure, an uninterruptible power supply (UPS) system is presented, the UPS System comprising at least one first input configured to be coupled to a primary power source and to a secondary power source, a second input configured to be coupled to a backup power source, an output configured to be coupled to at least one load, and at least one controller configured to receive a signal indicating that the secondary power source is prepared to provide secondary power to the UPS system, determine, responsive to receiving the signal, whether an energy level of the backup power source is above a threshold energy level, and control, responsive to determining that the energy level of the backup power source is above the threshold energy level, the UPS system to provide output power derived from the backup power source to the output.

Cloud based li-ion battery life optimization utilization with hybrid mode of operation

According to aspects of the disclosure, an uninterruptible power supply is provided comprising an input configured to be coupled to, and receive input power from, a circuit breaker, an output configured to be coupled to, and provide output power to, at least one load, an energy-storage-device interface configured to be coupled to, and receive back-up power from, an energy-storage device, and at least one controller configured to determine whether a current through the circuit breaker meets at least one over-current criterion, and control, responsive to determining that the current through the circuit breaker meets the at least one over-current criterion, the uninterruptible power supply to provide the output power to the load, the output power being derived from the input power and the back-up power.

Intelligent load control to support peak load demands in electrical circuits

Power supplies and methods of use thereof are provided, where a power supply includes an input configured to receive input AC power an output configured to provide output AC power to a load, at least one power converter coupled to the input and configured to convert the input AC power into the output AC power, a controller coupled the at least one power converter. The controller is configured to adjust at least one parameter of the output AC power provided by the at least one power converter, detect, in response to adjusting the at least one parameter of the output AC power, at least one of an adjusted input AC power or an adjusted output AC power, and determine that a fault has occurred based on the at least one of the adjusted input AC power or the adjusted output AC power.

Method to detect back-feed and mis-wiring events by a UPS system

A battery-charging system configured to charge a battery of a device to a nominal voltage includes a load-detection circuit, memory storing controller-executable instructions, and a controller configured to execute the instructions, which cause the controller to detect a load coupled to the battery above a first threshold load using the load-detection circuit, and control the battery-charging circuit to charge the battery to a high voltage in response to detecting the load above the first threshold load, wherein the high voltage is above the nominal voltage. The controller can be configured to execute other instructions, such as outputting a notification that the battery is being charged to a high voltage and/or controlling the battery-charging circuit to discharge the battery in response to detecting a reduced load or a user command.
