In the context of global “carbon neutrality”, new clean renewable energy has received more and more attention, and has also ushered in a rapid development stage. Battery cluster consists of battery cells connected in series, parallel or series parallel, and connected with energy storage converters and ancillary facilities to achieve independent operation of the battery assembly. Its includes battery management system, monitoring and protection circuit, electrical and communication interface and other components, limited cooling space, natural ventilation is difficult to achieve temperature control, easy to damage the life and safety of the battery.
At present, the energy storage thermal management mainly has two modes: air cooling and liquid cooling. Air cooling: reducing the battery temperature through gas convection; Liquid cooling: The battery temperature is reduced by liquid convection. Containers are widely used in the energy storage industry because of their strong mobility, quantifiable production, and on-demand expansion. However, because the heat dissipation space in the box is limited, it is difficult to achieve temperature control under natural ventilation, which is easy to damage the life and safety of the battery, so special air conditioners are needed to cool the equipment.
