摘要： The disclosure relates to a lighted connector configured to be attached to a rechargeable battery to allow the rechargeable battery to charged and/or discharged. The lighted connector includes a light that is operably connected to a control unit and/or processing component. The control unit and/or processing component may be programmed to control operation of the light in accordance with various parameters. In some embodiments, the light may be configured to be illuminated in response to an illumination triggering event, such as the lighted connector transitioning from a closed position toward an open position or a battery maintenance device associated with the lighted connector being connected to a power source. In addition, the lighted connector may be configured to be turned off in response to a shut-off triggering event, such as the lighted connector being correctly attached to a rechargeable battery. Furthermore, the light may be used in various ways to provide feedback to the user.

摘要： The present invention provides a charging system that includes a charging adapter and a mobile terminal. The charging adapter includes: a second USB interface; and an adjusting circuit for rectifying and filtering the mains supply to obtain an original power signal, for performing a voltage adjustment on the original power signal, and for outputting a power signal after the voltage adjustment. The mobile terminal includes a first USB interface. P first power wires in the first USB interface and P second power wires in the second USB interface are correspondingly coupled, and Q first ground wires in the first USB interface and Q second ground wires in the second USB interface are correspondingly coupled. Because each first power wire and a corresponding second power wire are coupled, at least two charging circuits can be provided, and the charging system supports charging with a large current more than 3 A.

摘要： When an abnormality occurs in a first voltage detector (4a), a control circuit (7) in an uninterruptible power supply device controls an inverter (3) in synchronization with an output signal (VI2D) from a second voltage detector (4b) to match a phase of a two-phase AC voltage (VO1, VO2) output from the inverter (3) with a phase of a two-phase AC voltage (VI1, VI2) supplied from a commercial AC power supply (51), and then turns on a semiconductor switch pair (S9, S10) and a bypass switch pair (S7, S8). Accordingly, even when an abnormality occurs in the first voltage detector (4a), the two-phase AC voltage can be supplied to a load (53) without instantaneous interruption.

摘要： A method for increasing workable power output and run time duration of a battery backup system is disclosed. A plurality of battery groups is provided. A microprocessor electrically connects the power output of a first battery group and a second battery group to a UPS. The microprocessor monitors the output voltage of the first and second battery groups. When the monitored output voltage of the first and second battery group falls below a predetermined level, the microprocessor electrically disconnects from the UPS the first battery group and electrically connects to the UPS the power output of another of the plurality of battery groups. The first battery group is configured to be re-connectable to the UPS after a time period equal to or greater than necessary to permit the output voltage of the first battery group to recover to about its nominal voltage rating.
