Abstract: A tungsten-base alloy material and a preparation method therefor. The preparation method comprises: 1) evenly grinding composite powder containing tungsten and zirconium oxide, and then performing annealing treatment at 700-1000° C. to obtain powder A; and 2) grinding and then compression moulding the powder A, and then performing liquid-phase sintering to obtain a tungsten-base alloy blank so as to obtain the tungsten-base alloy material.

Abstract: A molecular probe-based safety prewarning and fault location system for an electrochemical energy storage station includes a molecular probe label, a camera, and a host. The present disclosure realizes real-time safety prewarning of a fault of an electrochemical energy storage device based on a color change of a gas sensing region of the molecular probe label, and locates an abnormal electrochemical energy storage device based on a position marker region of the molecular probe label or a position of the camera on a slide rail when the camera is facing the molecular probe label. Operation and maintenance personnel of an energy storage station can obtain a prewarning signal in time and take a corresponding safety measure. The molecular probe technology is a drive-free technology with advantages of high sensitivity, low costs, and anti-interference. It has important application value for operation safety of a large-scale energy storage station.

Abstract: A shock absorption pedal with adjustable resistance includes: a fixed guide rail, fixedly connected to a vehicle body; a sliding frame, arranged in a groove of the fixed guide rail, and movable vertically along the fixed guide rail; and a support plate, fixedly connected to the sliding frame. A displacement regulating mechanism is arranged on the fixed guide rail. One end of the displacement regulating mechanism is arranged outside the groove of the fixed guide rail, and another end of the displacement regulating mechanism is connected to one end of a shock absorption spring. Another end of the shock absorption spring is fixedly connected to the sliding frame. A position of the sliding frame is regulable by the displacement regulating mechanism, to adjust a length of the shock absorption spring.

Abstract: Systems and methods for allocating energy including distributing and receiving energy using a mobile energy storage (MEES) system at locations of a power supplier in an energy market system by a user. Determine allocating amounts of energy for the MEES system and for each time interval for all time intervals for an upcoming operating time period based on a set of uncertain parameters using an optimization model. Base on calculating an objective function using uncertain parameters. Update the objective function using constraints. While optimizing the objective function for a value hierarchy associated with energy and reserve bidding scenarios for the user and delivery scheduling for the MEES system based upon the stored user risk preferences. Control scheduling of the MEES system between the locations of the power supplier, according to allocating of the amount of the electrical energy for the MEES system at the locations of the power supplier.
