ENERGY STORAGE DEVICE WITH A THERMAL MANAGEMENT SYSTEM

The present application relates to a thermal management system for an energy storage device (10), and an energy storage device (10). The energy storage device (10) comprises a plurality of battery cabinets (110), a battery pack being provided in the battery cabinet (110). The thermal management system comprises a water chilling unit (210) and a plurality of first pipeline assemblies. The plurality of first pipeline assemblies correspond to the plurality of battery cabinets (110) on a one-to-one basis, and are connected in parallel to the water chilling unit (210). Each first pipeline assembly comprises two battery cabinet pipelines (220), one end of each of the two battery cabinet pipelines (220) is respectively connected to a water intake side and a water output side of the water chilling unit (210), and the other end of each of the two battery cabinet pipelines (220) extends into the corresponding battery cabinet (110) and is connected to a water-cooled plate (120) of the battery pack in the battery cabinets (110). According to the thermal management system, the design with a main pipeline is abandoned, the number of first pipeline assemblies is not limited, and parallel nodes of the plurality of first pipeline assemblies are no longer limited to the main pipeline, such that the scope of application of the thermal management system can be widened.
