Description
technical field [0001] The invention relates to the technical field of energy storage batteries, in particular to a battery pack casing and an energy storage battery assembly. Background technique [0002] The power generation of a normal photovoltaic system is affected by changes in the intensity of sunlight at different times of the day, and the power supply is unstable. Therefore, it is necessary to set up an energy storage battery to store electric energy, and the stored electric energy is stably output to the grid for use. The energy storage battery is integrated with photovoltaic modules. Connected to store the electrical energy converted by photovoltaic modules. [0003] At present, the electrical connection and structural fixation of the battery cell module of the energy storage battery are completed inside the product casing; and the product handle is designed to be embedded with accessories or the structure of the handle is reserved on the product casing. This lea...
