Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, specifically a residential liquid-cooled stacked energy storage system. Background Technology

[0002] The accelerating arrival of the low-carbon era is driving a transformation in the energy structure. Traditional thermal power generation will be phased out, and new energy sources such as solar, wind, hydro, and ocean energy will replace traditional energy. With the advent of the smart home era, people's lives have become inseparable from electricity, and home energy storage devices are becoming increasingly abundant. During the day, these devices store excess electricity generated from new energy sources, and at night, they can provide power for the entire household. People's demand for the capacity of energy storage devices is also gradually increasing. This increased capacity demand requires higher voltage and higher current for these devices, leading to increased heat generation. Most energy storage devices on the market rely on natural heat dissipation, which, if not properly dissipated, significantly impacts the lifespan, safety, and conversion efficiency of the battery cells. Furthermore, while energy storage capacity has increased, these devices are also very bulky and difficult to install, severely affecting production and after-sales maintenance costs.
