Abstract

The invention provides a power supply system ground simulation comparison test system and method, and the system comprises a power supply system, 1553 bus equipment, a system console, a solar array simulator, a high-voltage stabilized power supply, an electronic load, a power distributor, a high-low temperature box, a data collection instrument, and an equalization processor. The power supply system comprises a storage battery pack, a bus voltage adjusting unit and a storage battery charging control unit, wherein the storage battery pack comprises a lithium ion storage battery pack A, a lithium ion storage battery pack B and a lithium ion storage battery pack C; the bus voltage regulating unit comprises a shunt regulator, a power manager, a discharge regulator and a system controller; thestorage battery charging control unit includes a charging controller. According to the invention, the actual temperature difference of each group of on-orbit batteries is simulated through the high-low temperature box, which is closer to the real working condition of on-orbit operation of the spacecraft, and the working capability and reliability of the multi-unit grid-connected aircraft power supply system can be verified.

Description

technical field [0001] The invention relates to a ground simulation comparison test system and method of a power supply system, which belongs to the field of aircraft power supply-power supply system ground simulation test system design. Background technique [0002] With the rapid development of my country's aerospace technology, the development of spacecraft presents the characteristics of high power, long life, multiple units, and high reliability. Lithium-ion batteries have been widely used in energy storage batteries on spacecraft. Lithium-ion batteries have the characteristics of high specific energy, high working voltage, low self-discharge rate, long cycle life, and good safety. Strict, especially in the case of multi-unit lithium-ion battery grid-connected power supply, the temperature difference between the battery packs and the voltage difference of the battery cells in each battery pack will affect the service life of the lithium-ion battery, and in serious cases...
