Abstract: A method includes: detecting initial capacities of multiple to-be-grouped battery cells, and grouping, among the to-be-grouped battery cells, battery cells to obtain a first battery pack; detecting an initial SOC of each battery cell in the first battery pack, and grouping the battery cells in the first battery pack to obtain a second battery pack; simulating a charging and discharging process of the second battery pack to obtain charging data and discharging data corresponding to the battery cell; and determining a grouping efficiency of the second battery pack based on the charging data, the discharging data, and a nominal capacity.

Abstract: Disclosed are a grain boundary and surface-doped rare earth zirconium-based ceramic material and a preparation method and application thereof, and part of doped elements are positioned at the grain boundary and surface of the rare earth zirconium-based ceramic material by a step-by-step doping method. The sintering activity of the rare earth zirconium-based ceramic material can be changed by adjusting the type and content of doping elements at the grain boundary and the surface, thereby enabling the control of the grain size and the grain boundary number and characteristics of the rare earth zirconium-based ceramic material, and finally optimizing the properties, such as electrical and mechanical properties, of the material. The doping method has the advantages of simple process, low cost and high universality, and can meet the requirements of different rare earth zirconium-based ceramics on doping elements, and thus is suitable for large-scale application.

Abstract: A manufacturing method of a thermoelectric conversion device having a textile structure. The thermoelectric conversion device having a textile structure uses one or multiple types of thermoelectric yarns as thermocouples of a thermoelectric generator structure, and uses elastic insulating yarns as a main carrier portion of a textile article. The invention utilizes the characteristic of a textile article of having woven and overlapping warp and weft yarns, and the thermoelectric yarns are woven into a thermoelectric generator textile article by using a conventional weaving technique. The thermoelectric transfer performance and the performance of the main carrier thereof are adjusted by varying an interweaving structure of the textile article, placement positions of the thermoelectric yarns, and the length of the thermocouples thereof.

Abstract: The present application discloses at least a method, apparatus, and system for automatic refueling of a driverless vehicle. A specific implementation of the method includes: sending refueling request information when a fuel amount is lower than a preset value and a refueling condition is satisfied; receiving preselected gas station information corresponding to the refueling request information; determining, from the preselected gas station information, destination gas station information and driving route information of a destination gas station; sending refueling request information after arriving at the destination gas station based on the driving route information of the destination gas station; turning off an engine and/or an electric motor after receiving refueling permission information corresponding to the refueling request information, opening a fuel tank cap, and sending refueling confirmation information; and closing the fuel tank cap after receiving refueling completion information.
