The invention relates to the technical field of spacecraft safety, in particular to a spacecraft black box full-life-cycle power management system. Comprising a bus, a plurality of solar cell arrays, a storage battery pack, a bus voltage sampling circuit, a plurality of shunt circuits and a filter circuit, and the solar cell arrays and the shunt circuits are the same in number and are in one-to-one correspondence; the solar cell arrays are respectively connected with one end, far away from the load, of the bus; one end of the bus is connected with a second relay switch, a third relay switch and a fourth relay switch, the other end of the second relay switch is connected with the computer module through the power conversion circuit, and the other end of the third relay switch is connected with the Beidou short message module through the power conversion circuit. The fourth relay switch is connected with the UV measurement and control module through the power conversion circuit. The method supports the whole life cycle power management of the spacecraft black box, increases the support of active section work, prolongs the working time of the spacecraft black box, and prolongs the application range of the spacecraft black box.
