Abstract: An automatic pathogen-from-expiration detection system includes a gas pathogen recovery unit, a pathogen concentration unit and a sample detection unit. The method includes making the sample recovered by the gas pathogen recovery unit enter the pathogen concentration unit; in the pathogen concentration unit, gradually biasing the pathogen particles in the sample to the positive electrode side into the concentration channel under the action of the electrode; applying a fluctuating voltage greater than zero to a single sub-positive electrode, and alternating the voltage of the sub-positive electrode adjacent thereto with the fluctuating voltage, so that a varying potential difference is formed between the adjacent sub-positive electrodes, wherein the pathogen particles are gradually enriched in the middle region of the two adjacent sub-positive electrodes, and the concentrated sample is driven to move to the sample detection unit; and immediately detecting the concentrated sample in the sample detection unit.

Abstract: An automatic pathogen-from-expiration detection system and method is disclosed. The system comprises a gas pathogen recovery unit, a pathogen concentration unit and a sample detection unit.

Abstract: The automatic identification hydrogen refueling system includes a ground positioning module, a hydrogen storage module, a mechanical arm, a refueling module, an automatic identification module and an information processing module. The ground positioning module is provided with a sensor. A hydrogen conveying pipeline is connected with the refueling module. The hydrogen storage module is arranged at a tail end of the ground positioning module, and connected with the mechanical arm, the information processing module and the hydrogen conveying pipeline. The information processing module controls the mechanical arm to drive the refueling module to preliminarily align a refueling connector after receiving a sensor signal.

Abstract: The disclosure relates to the technical field of batteries, and particularly relates to a battery container, a battery pack, and a battery assembling method. The battery container includes a bottom plate, a first fixing member disposed on the bottom plate, and a second fixing member disposed on the bottom plate. The second fixing member and the first fixing member are arranged opposite to each other. A battery accommodating part is formed between the first fixing member and the second fixing member. A surface of the first fixing member facing the second fixing member has a first groove, and a surface of the second fixing member facing the first fixing member has a second groove. The first groove and the second groove are configured to remove a clamp from the battery container during assembly.
