摘要： The power supply system includes a first power supply and a second power supply connected to the first power supply, and a switch device. The battery unit is charged by the first power source and supplies power to the load when power is not supplied from the first power source to the load. The switching device cuts off a connection between the first power supply and the second power supply when a voltage of the first power supply becomes equal to or lower than a threshold value.

摘要： The present disclosure relates to a method of controlling power supply units (1-9) of a base station (10), and a device (20) performing the method. In an aspect, a method of a base station scheduling device (20) of controlling power supply units (1-9) of a base station (10) is provided. The method comprises acquiring (S102a-c) information indicating a value of voltage input to at least one of the power supply units (1-9) of the base station (10), determining (S103) from said value if the voltage input to said at least one of the power supply units (1-9) is sufficient, and if not determining (S104) power demand of the base station (10), and deactivating (S105) said at least one power supply unit, if remaining power supply units (1-9) is capable of supplying the demanded power.

摘要： A distributed power network includes a power bus infrastructure distributed over a region with node points provided to interface with controllable power nodes. Each power node can be connected to an external power device such as a DC power sources, a DC power load, or a rechargeable DC battery. The power nodes form a communication network and cooperate with each other to receive input power from DC power sources and or rechargeable DC batteries connected to the power bus infrastructure and distribute the power received therefrom to the power bus infrastructure for distribution to the DC power loads and to rechargeable DC batteries.

摘要： A power sourcing equipment (PSE) device for controlling delivery of electric power to a powered device (PD) connected to the PSE device comprises a first input port for reception of input data and electric power from a power over Ethernet (PoE) device such as a PoE switch, a second input port for reception of electric power from a power source other than the PoE device and an output port for provision of the input data received at the first input port and the electric power received at the second input port to the PD. The PSE device further comprises control circuitry that is configured to determine a discontinuation of reception of electric power from the PoE device and configured to, in response to a determination of a discontinuation of reception of electric power from the PoE device, control discontinuation of provision of the electric power to the PD.

摘要： A power supply system includes: a first power supply circuit for supplying, to a first load device, DC power output from a first power generation device; and a second power supply circuit for supplying, to a second load device, DC power output from a second power generation device. In a case where the electric power output from the second power generation device is supplied to the first load device, the first power supply circuit and the second power supply circuit are connected to each other after the output voltage of the second power generation device is lowered.

摘要： A power feeding control device controls a power feeding system including a plurality of battery cells feeding power to a load, a bypass lines which connects or disconnects each of the battery cells and the load, an external power feeding unit which is connected in parallel with the load and feeds power to the load. Before the bypass line starts switching of a connection state between each of the battery cells and the load, supply voltage from the external power feeding unit to the load is increased. Further, after the bypass line switches the connection state between each of the battery cells and the load, the supply voltage from the external power feeding unit to the load is decreased.

摘要： The invention is a motorcycle jump-start support system whose primary subsystem is an umbilical cable that attaches to a motorcycle battery's terminals and whose two-polarity connector resides outside the battery compartment and motorcycle seat such that it may be interfaced without having to remove the motorcycle seat once it has been installed. Its two-polarity connector is operative to ensure that accessory cables connected to it can only be connected in one orientation. Consequently, connecting a jumper accessory cable to the umbilical cable will preserve the correct connection polarity.

摘要： Systems and methods for extending battery backup power to an electrical substation include or utilize a latching direct current contactor having a current input and a current output, and a controller configured to monitor all alternating current inputs to an electrical substation, and to trip the latching direct current contactor when all alternating current inputs and auxiliary power to the electrical substation are dead, whereby direct current does not flow through the latching direct current contactor when supplied loads in the substation, such as relaying and communications, are not needed, and to close the latching direct current contactor when at least one alternating current input or auxiliary power is live, whereby direct current flows through the latching direct current contactor when the direct current supplied loads are needed.

摘要： An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system.
