A maintenance bypass (MBP) system for an uninterruptible power supply (UPS) includes a first switch having at least three positions that provide different couplings of a power source, a load, a power input of a UPS and a power output of a UPS and including a first contact set configured to indicate at least one transition between positions of the at least three positions. The system further includes a second switch configured to enable transition of the first switch between at least two of the positions and including a second contact set configured to indicate actuation of the second switch. The first switch may include a rotary switch and the second switch may include a pushbutton switch.

UPS maintenance bypass systems using mode signaling

Uninterruptible power supplies (UPSs) are provided including a processor and a voltage sensor circuit in communication with the processor. The voltage sensor circuit is configured to sense a center point voltage (CPV) of a battery module associated with the UPS and provide the sensed CPV to the processor. The processor is configured to receive the sensed CPV of the battery module, determine if the CPV is less than a predetermined voltage and turn off all battery chargers associated with the battery module if the CPV is determined to be less than the predetermined voltage.

Battery management systems having battery failure detection and related methods and uninterruptible power supplies (UPSs)

A battery module is provided including a battery module connector configured to engage with a backplane connector on a backplane board associated with an uninterruptible power supply (UPS). When the battery module connector is engaged with the backplane connector a circuit is completed that instantaneously indicates to the UPS that the battery module is connected. When the battery module connector is disengaged from the backplane connector the circuit is opened and instantaneously indicates to the UPS that the battery module is disconnected.

Battery modules having detection connectors and related systems

A system for providing power is provided including an uninterruptible power supply (UPS) coupled to a first power source, the UPS including at least one battery therein; at least one external battery module (EBM) coupled to the UPS and a second power source, the second power source being different and separate from the first power source. Each of the at least one EBMs include at least one battery string; and a super charger coupled to the at least one battery string and the at least one battery in the UPS, the super charger being configured to charge the at least one battery string and the at least one battery in the UPS when power from the first power source is removed. EBMs and UPSs are also provided herein.

Methods, systems and devices for extending run-times of uninterruptible power supplies (UPSs)

Systems for providing power are provided including an uninterruptible power supply (UPS) coupled to a first power source, the UPS including at least one battery therein; and at least one external battery module (EBM) coupled to the UPS and a second power source, the second power source being different and separate from the first power source. Each of the at least one EBMs include a communication circuit configured to communicate with the UPS and/or other EBMs; at least one battery string; and a battery charger coupled to the at least one battery string and the at least one battery in the UPS, the battery charger being configured to charge the at least one battery string and the at least one battery in the UPS responsive to a communication from the EBM through the smart card when power from the second power source is removed. Related EBMs and UPSs are also provided.

Methods, systems and devices for managing batteries of uninterruptible power supplies (UPSs) and related external battery modules (EBMs)

Battery module having detection connectors and related systems

Embodiments of the present inventive concept provide an external battery module (EBM) including a communication server board (CSB) slot configured to receive a CSB, wherein the EBM operates regardless of whether the CSB is positioned in the CSB slot; and a battery charger slot configured to receive a battery charger, wherein the EBM operates regardless of whether the battery charger is positioned in the battery charger slot.

Adaptable external battery modules and related systems

An uninterruptible power supply (UPS) system includes first and second busses, a first switching circuit configured to selectively couple an AC source to the first and second busses and a second switching circuit configured to selectively couple the first and second busses to a load. The system also includes a storage capacitor and a third switching circuit configured to couple the storage capacitor between the first and second busses. The system further includes a control circuit configured to control the first, second and third switching circuits to generate an AC voltage at the load.
