5results about How to "Improve power supply efficiency" patented technology

The invention provides an in-vehicle device and an operation method of the in-vehicle device. The efficiency of power supply in a monitoring system of a vehicle can be improved. An in-vehicle device mounted on a vehicle is provided with a control unit that controls the in-vehicle device when either or both of a change in position of the vehicle and a time during a period from starting to stopping of an engine of the vehicle satisfy a predetermined condition, and that controls the in-vehicle device when the change in position of the vehicle and the time satisfy the predetermined condition. Information is generated for supplying power from a battery in the vehicle to a system for monitoring the vehicle.

The application relates to a hydrogen fuel cell system, which comprises a water bath assembly, a hydrogen storage module and a cell stack module. The water bath assembly contains cooling liquid and the hydrogen storage module is arranged in the water bath assembly and has a solid hydrogen storage unit. The cell stack module comprises a plurality of cell sheets and radiating fins, and the cell sheets are connected with the hydrogen storage module through a hydrogen supply pipeline. The hydrogen storage module supplies hydrogen fuel for the cell sheets. The heat exchange module is arranged between the water bath assembly and the radiating fins, and the cooling liquid circulates among the water bath assembly, the heat exchange module and the radiating fins. The hydrogen storage module cools the high-temperature cooling liquid brought out from the cell stack module. The high-temperature cooling liquid brought out from the cell stack module heats the hydrogen storage module, so that the hydrogen supply pressure and the hydrogen supply flow of the hydrogen storage module are not affected by the excessively low temperature of the hydrogen storage module. The electric energy required for the self-radiation of the cell stack module and the heating of the hydrogen storage module is saved, and the power supply efficiency of the cell stack module to the motor is improved.

This invention discloses an intelligent collaborative power generation, grid, load, and energy storage operation and management system, belonging to the field of power generation, grid, load, and energy storage management technology. It involves numbering and collecting information from power stations within a monitoring area, dividing the monitoring time period into time segments, analyzing the power supply volume of power stations within each time segment to predict the relationship between the power supply capacity and demand of each power station, establishing a power dispatch circle centered on the power station, analyzing the overall support capacity of the power dispatch circle for power stations with insufficient power supply capacity, issuing power shortage warnings based on trigger conditions, analyzing the overall status of power stations within the power dispatch circle when the power dispatch circle provides sufficient support, considering the number of power stations with insufficient power supply capacity, and providing suggestions for establishing new power stations, and providing energy storage locations and new power station construction locations when it is determined that the power dispatch circle needs to establish new power stations. This invention efficiently utilizes existing power resources through real-time analysis of supply and demand matching and support dispatch.

This utility model provides an energy-saving pressurized water supply device. The device includes a main body comprising a water tank, an air pump for pressurizing the tank, and an air inlet pipe connected to the pump for air intake into the tank. One bottom side of the water tank is connected to an outlet pipe, and the top front end of the tank is connected to an inlet pipe. The side of the outlet pipe is connected to a drain pipe, which has a drain valve. A filter screen for filtering impurities is installed inside the outlet pipe, and a cleaning mechanism is provided corresponding to the filter screen. The energy-saving pressurized water supply device allows the filter screen to be cleaned with a brush without disassembling the pipes by moving the cleaning mechanism up and down.
