All the devices are installed on the phenolic board 5, and the phenolic board 5 is numerically controlled by aluminum to ensure the assembly accuracy. The 6 input / output terminals are respectively: ground power input terminal 2, generator input terminal 11, battery 1 input terminal 8, battery 2 input terminal 7, generator output terminal 3, and battery output terminal 4. The fuses are selected for their small size, light weight, and high reliability;

The generator busbar 13 is electrically connected to the battery busbar 6 through two 200A diodes 10, and the electric energy of the generator busbar 13 can only flow unidirectionally into the battery busbar 6;

[0027] The generator input terminal 11 and the ground power input terminal 2 are used as power supply inputs. Among them, the generator input terminal 1 inputs the electric energy generated by the generator system into the positive power distribution panel, and the ground power input terminal 2 inputs the ground power supply into the positive power distribution panel.
