The invention discloses a charging control method, electronic equipment, an electric energy device and a storage medium, and the charging control method comprises the steps: obtaining a target charging path of a battery from a current state to a target state according to the current state information of the battery, the target charging path is the estimated charging path with the shortest charging time in a plurality of estimated charging paths for charging the battery from the current state to the target state; and controlling battery charging according to the target charging path. The method can shorten the battery charging time as much as possible and improve the charging speed, thereby improving the battery charging capability.

The present application relates to the field of temperature measurement, in particular to a kind of metal organic framework crystal material and its preparation method and application.The present application provides a kind of metal organic framework crystal material, wherein the crystal material is connected body 2,6-di (2,4-dicarboxyphenyl) -4- (phenyl) pyridine and Zn (II) connected with the crystal material with periodic three-dimensional network structure.The metal organic framework crystal material provided by the present application still keeps the afterglow characteristic under the condition of smaller particle size, and the charging time is shorter;At the same time, the decay time of the metal organic framework crystal material of the present application is seconds, and the light source only needs ordinary ultraviolet semiconductor light source, and the camera can record the time / color of afterglow decay, as the basis for temperature judgment, which greatly reduces the temperature measurement cost and simplifies the measurement process;In addition, the metal organic framework crystal material of the present application can be synthesized below 120 DEG C, which reduces the production cost and danger.

The invention relates to the technical field of phased array radar power supply and distribution, in particular to an intelligent multi-stage slow start device applied to a radar power supply and distribution system, and the intelligent multi-stage slow start device is connected between an input terminal and an output terminal of the radar power supply and distribution system. The intelligent multi-stage slow start device comprises a main loop module, a state acquisition module and a decision control module, the main loop module is composed of a main relay and n slow start branches which are connected in parallel. Each slow start branch is composed of a branch relay and a current-limiting resistor which are connected in series. The state acquisition module is composed of a voltage acquisition unit used for acquiring output voltage in real time and a temperature acquisition unit used for acquiring the temperature of each current-limiting resistor in real time. The decision control module is composed of a central processing unit, a voltage reference adjusting unit, a comparison unit and a driving unit, and is used for controlling the on-off of the branch relays of the n slow start branches. According to the device, low-cost, low-heat-consumption and high-reliability slow start is realized, and higher-level system protection is provided.

The application relates to a medical gas pipeline welding inner sealing device, belonging to the pipeline welding field, which comprises a first pipe body, a second pipe body and a third pipe body arranged at the two ends of the first pipe body respectively, the first pipe body, the second pipe body and the third pipe body are coaxial, pressure expansion pieces are arranged between the first pipe body and the second pipe body and between the first pipe body and the third pipe body, a driving assembly for driving the second pipe body and the third pipe body to move towards each other so that the two pressure expansion pieces are extruded and expanded is arranged on the first pipe body, when the application is used, the first pipe body, the second pipe body and the third pipe body are slid into a pipeline to be welded, the two pressure expansion pieces are located at the two sides of a weld seam, under the action of the driving assembly, the two pressure expansion pieces are expanded under pressure and abut against the inner wall of the pipeline, so that the pipeline is sealed, the sliding in and sliding out are relatively smooth, the operation is convenient, the spacing between the two pressure expansion pieces is small, the amount of inert gas is small, the filling time is short, the construction cost is low, and the efficiency is high.
