Description

Technical Field

[0002] Solar cold storage is a cold storage that uses solar photovoltaic power generation system to provide power supply. Solar photovoltaic power generation system can directly convert sunlight into electrical energy without other fuels, making energy utilization more efficient. The electricity required by the cold storage can be met by self-generation, reducing the demand for traditional power grids and thus reducing energy costs. Therefore, it has been widely used today, and solar power generation requires energy storage batteries to store electricity.

[0003] Existing solar cold storage energy storage batteries generate heat during the charging and discharging process. If the heat cannot be dissipated in time, the temperature will continue to rise, which may lead to shortened battery life, degraded performance, and even safety problems such as thermal runaway and fire. Therefore, cooling treatment is required. At the same time, in a low temperature environment, the chemical reaction rate of the battery will slow down, the internal resistance will increase, and the discharge capacity will decrease. Appropriate heating can improve the battery performance so that it can work normally at low temperatures, so heating treatment is required.

[0004] For this purpose, a solar cold storage energy storage battery cooling and heating device is proposed. Utility Model Content
