In an embodiment, at least one of the energy storage module 20, the power converter 30, the control module 40, the bus module 50 and the uninterruptible power supply 60 is detachably connected to the cabinet 11, so that maintenance is facilitated for the energy storage module 20, the power converter 30, the control module 40, the bus module 50 or the uninterruptible power supply 60 when the cabinet door 12 is opened, and maintenance cost is reduced.

In summary, in the energy storage system 100 of the present application, the energy storage module 20 and the power converter 30 are integrated in the cabinet 10, so that the energy storage system 100 integrates multiple functions, which is beneficial to improving the integration level of the energy storage system 100, not only facilitating transportation, but also facilitating assembly and installation of the production line of the energy storage system 100, and reducing cost; and the energy storage module 20 is separated from the first chamber 141 and the power converter 30 is separated from the second chamber 142 by the partition 13, so that mutual influence between the energy storage module 20 and the power converter 30, such as mutual thermal interference or cross-firing between the two, is reduced.

The foregoing is merely illustrative of specific embodiments of the present application, and the present application is not limited to these embodiments, but any changes or substitutions within the technical scope of the present application are intended to be included in the scope of the present application.
