A new charging pile power distribution system. The charging pile system includes a charging pile main control module, a charging pile controlled module, a charging billing module, a charging controller module, and a charging power supply module. The microgrid subsystem includes a wind power generation module, a photovoltaic power generation module module, power storage module, and micro-grid control module; the city grid subsystem includes a city grid module, a power load module, a city grid power consumption estimation module, a primary power storage module, a city power grid control module, and a micro-grid grid-connected module ; It can solve the waste of electricity in scattered micro-grids, which is beneficial to the peak-shaving and valley-filling of the national grid; through the monitoring of the charging power of each charging pile in the area and the statistics and regulation of the user's electricity consumption according to the electricity consumption estimation module of the city grid, the charging and distribution Control the charging power to provide charging users with a variety of charging modes for users to choose. By controlling the change of charging unit price, users are encouraged to use full power charging during low power consumption periods, so as to maintain the efficient circulation of electric energy in the city grid.

The invention discloses a self-unlocking power conversion circuit, which comprises a thermal battery powering switch and the like, wherein a third sampling resistor and a first reference source are connected with a positive electrode input end of a first logic judgment operational amplifier, an output end of the first logic judgment operational amplifier is connected with the thermal battery powering switch, a first sampling resistor and a second sampling resistor, the first sampling resistor is connected in series with the second sampling resistor, the third sampling resistor is connected with the first reference source, a fourth sampling resistor is connected with a second reference source, and the fourth sampling resistor and the second reference source are both connected with a negative electrode input end of a second logic judgment operational amplifier. The self-unlocking power conversion circuit can effectively prevent a missile thermal battery from affecting operation of a carrier power supply during the activation process of the thermal battery when the carrier power supply and the missile thermal battery are in a grid-connected power supply state, and can prevent the problem of reliable output of the thermal battery after the thermal battery is activated.
