The cabinet also includes a plurality of energy storage modules, the energy storage modules being arranged in the first space, the energy storage modules being stacked in a first direction of the energy storage cabinet, the first space and the second space being arranged side by side in a second direction perpendicular to the first direction; and a control unit, the control unit being arranged in the second space and the control unit is electrically connected to the energy storage module.

Abstract: An energy storage module and an energy storage cabinet. The energy storage module includes: an energy storage unit, the energy storage unit including a plurality of cells, and the plurality of cells being arranged in sequence in the thickness direction of the cells; a first side plate and a second side plate, the energy storage unit being provided between the first side plate and the second side plate; and support beams, the support beams extending in the thickness direction of the cells and being connected between the first side plate and the second side plate so as to enable the first side plate and the second side plate to clamp the energy storage unit, and the support beams being arranged on at least one side of the energy storage unit in the width direction of the cells.

Abstract: An energy storage cabinet includes: a cabinet, and a first space and a second space formed in the cabinet. Multiple battery modules are disposed in the first space and stacked in a first direction of the energy storage cabinet, and the first space and the second space are disposed side by side in a second direction of the energy storage cabinet perpendicular to the first direction. A controller disposed in the second space and electrically connected to the battery modules.

Abstract: The present disclosure provides a battery module and a battery pack. The battery module includes: multiple cells and an outer frame. The outer frame includes: four support columns, two side plates, and two end plates. The two side plates are arranged opposite to each other. The two end plates are arranged opposite to each other. The four support columns are respectively connected between end portions of the side plates and the end plates. One of a top and a bottom of the support column is provided with a support platform and another is provided with a fitting hole. The support platform of one battery module is fittable in the fitting hole of another battery module.

Abstract: The present disclosure provides a temperature-responsive self-degradable temporary plugging agent and a preparation method thereof as well as its application in plugging the wellbore, which relates to the technical field of oilfield exploitation. The temporary plugging agent provided in the present disclosure includes preparation raw materials of the following mass percentages: monomer 4-6%, crosslinker 0.2-1%, initiator 0.02-0.06%, degradation catalyst 0.05-0.1%, chain transfer agent 0.01-0.05%, and the balance water. The temporary plugging agent of the present disclosure is liquid before gelling, with a low viscosity and a good fluidity, and easy to be pumped. When being pumped into the wellbore, the temporary plugging agent may crosslink at the temperature of the reservoir section, with good gelling properties. At the end of the operations, it can be degraded by itself, without drilling tools, with no need for gel breaking, and with no need for additional degradation promoters.
