[0002] Energy storage cabinets are used in power supply systems. According to actual power supply needs, power supply from the grid or energy storage cabinets can be selected. Energy storage cabinets generally have battery units, energy storage converters PCS, control units, etc. The energy storage converters PCS convert external AC power into DC power and transmit it to the battery units for storage and processing through the control unit. A control box is generally installed in the energy storage cabinet as a control unit. The layout of the components inside the existing control box is relatively scattered, and the wires between the components are also messy, which makes the control box larger and heavier, which is not conducive to installation and transportation. In addition, the layout of the existing control box is unreasonable, which is easy to cause signal interference and affect the control performance. Utility Model Content
