Abstract: A method for generating and outputting a message is implemented using an electronic device the stores a computer program product and a text database. The text database includes a main message template, a template text that includes a placeholder, and a word group that includes a plurality of preset words for replacing the placeholder. The method includes: in response to receipt of a command for execution of the computer program product, displaying an editing interface including the main message template; in response to receipt of user operation of a selection of the main message template, displaying the template text; in response to receipt of user operation of a selection of one of the preset words via the user interface, generating an edited text by replacing the placeholder with the one of the preset words in the template text; and outputting the edited text as a message.

Abstract: A scheduling method for charging multiple electric vehicles includes: get a sorted list of an operation period; get an estimated charging power consumption required for charging each electric vehicle when each electric vehicle is connected to one of the charging machines and get an instant power consumption of an electricity consuming field; control one or more of the charging machines to correspondingly charge one or more of the plurality of electric vehicles with higher priority in a departure order based on the departure order information in the sorted list when a sum of the instant power consumption and the estimated charging power consumptions is greater than a regulated power consumption that is smaller than an upper limit power consumption of the electricity consuming field, thereby preventing the instant power consumption of the electricity consuming field from exceeding the upper limit power consumption.

Abstract: A method of charging management of an electric vehicle includes: get an initial power of the electric vehicle; calculate an actual power consumption of the electric vehicle in an operation period; get a remaining power by subtracting the actual power consumption from the initial power; get a predicted power consumption of the electric vehicle in a next operation period; control a charging machine to charge the electric vehicle after the electric vehicle being connected to the charging machine until a power of the electric vehicle reaches the predicted power consumption from the remaining power, thereby avoiding wasting power due to overcharging.

Abstract: A stability analyzing apparatus is in cooperation with a DC power system having a bus terminal connected to at least a load, and comprises a perturbation signal generating module, a signal processing module and a determining module. The perturbation signal generating module generates a perturbation signal injected into the bus terminal to obtain a transfer function of the bus terminal impedance. The signal processing module is electrically connected to the perturbation signal generating module and calculates the slope of the transfer function of the bus terminal impedance to obtain a transfer function of the bus terminal impedance slope. The determining module is electrically connected to the signal processing module and determines the stability tendency of the DC power system according to the transfer function of the bus terminal impedance slope. A stability analyzing method is also disclosed.

Abstract: A dual input power supply system/method providing uninterruptable power to a protected load device (PLD) is disclosed. The system includes hybrid switch devices (HSD) comprising semiconductor and relay/contactors that minimize the OPERATE/RELEASE times associated with switchover from a primary power source (PPS) to a secondary power source (SPS). An operate/release controller (ORC) monitors the condition of power provided by the PPS and SPS and determines the optimal transfer time to activate the HSD and switch between the PPS and SPS based on the PLD configuration. Use of the HSD in conjunction with the ORC permits a wide variety of series permutated AC/DC primary (PPS) and secondary (SPS) power sources, EMI snubbers (EMS), bridge rectifier diodes (BRD), AC-DC converters (ADC), and DC-DC converters (DDC) to service the PLD, while simultaneously reducing storage capacitors normally required to cover the OPERATE/RELEASE times associated with traditional PPS/SPS switchover/failover delays.
