Embodiment 1

[0041] As mentioned in the background technology section, the cooling devices used in conventional energy storage battery cabinets are generally integrated inside the battery cabinets. In the scenario where energy storage battery Occupying the internal space of the energy storage battery cabinet will lead to a decrease in the space utilization rate and energy efficiency of the energy storage battery cabinet; at the same time, it will also increase the weight and volume of the energy storage battery cabinet. Both will cause adverse effects; and, due to the limitation of the internal space of the energy storage battery cabinet, the volume of the cooling device will be small, and the heat dissipation environment of the cooling device will be poor, so that the heat transfer performance of the cooling device will also decrease, and the cooling efficiency will be lower. Low, at the same time, is also not conducive to maintenance.

[0042] To this end, the present invention provides ...

Embodiment 2

[0081] Please refer to Figure 4-Figure 8 , Figure 4 It is a schematic flow chart of the control method of the distributed energy storage system provided by the present invention, Figure 5 It is a schematic flow chart of the first specific implementation manner of step S2, Figure 6 It is a schematic flow chart of the second specific implementation manner of step S2, Figure 7 It is a schematic flow chart of the third specific implementation manner of step S2, Figure 8 It is a schematic flowchart of the fourth specific implementation manner of step S2.
