Technical Field

[0001] This utility model relates to the field of energy storage power technology, and in particular to a portable energy storage power supply. Background Technology

[0002] In recent years, with the popularity of outdoor sports, users have increased their demand for energy storage devices and have higher quality requirements. The structure of energy storage power supplies can be referenced in Chinese utility model patent application number CN202321558038.1, entitled "An Energy Storage Battery Box for Fireproofing and Temperature Control." Traditional energy storage power supplies require specially customized cell module isolation plates, which cannot flexibly change the number of cells. The development cycle for isolation plates is long, making it difficult to quickly respond to market demands. When it is necessary to quickly increase or decrease the number of cells, new molds must be created, resulting in low efficiency. Furthermore, the large number of internal supports in the chassis leads to higher costs, heavier overall weight, and poor portability. Utility Model Content
