Description

Technical Field

[0001] This utility model belongs to the field of battery equipment technology and relates to a low-voltage lithium iron phosphate battery housing. Background Technology

[0002] As the global energy structure shifts from traditional fossil fuels to renewable energy sources (such as solar and wind power), the intermittency and volatility of renewable energy have become increasingly apparent. For example, solar power generation relies on sunlight and can only generate electricity during the daytime when there is sunshine; cloudy or rainy weather conditions can affect its efficiency. Wind power generation, on the other hand, depends on the strength and stability of wind. Energy storage systems can effectively solve these problems by storing excess electricity and releasing it when energy production is insufficient, thus ensuring the stability and continuity of energy supply.

[0003] Low-voltage battery boxes, as an important component of energy storage systems, play a crucial role in distributed energy storage scenarios such as residential energy storage and small-scale commercial energy storage. Taking residential energy storage systems as an example, when solar panels generate excess electricity during the day, the low-voltage battery box can store this electricity for the household to use at night or when sunlight is insufficient, reducing dependence on the power grid and achieving energy self-sufficiency.

[0004] In recent years, battery technology has made continuous progress, with significant improvements in performance from various technologies, including lead-acid batteries and lithium-ion batteries. For example, the energy density of lithium-ion batteries has increased dramatically, enabling them to store more electrical energy in a smaller volume and weight. At the same time, their cycle life has been extended, allowing the batteries to maintain good performance even after multiple charge-discharge cycles.

[0005] As a container for battery installation, the battery box must not only have the structural strength to meet the requirements of battery installation, transportation and use, but also be made of non-flammable materials and have the functions of ventilation and heat dissipation for the battery and installation of lead wires.
