A current-limiting charging control circuit of a power supply subsystem for a satellite comprises a storage battery charging bus unit, a charging current sampling control circuit, a telemetering circuit, a charging current loop control circuit, a charging voltage loop control circuit, a charging current gear switching and telemetering circuit and a storage battery pack. The output current of the storage battery charging bus unit is collected by the charging current sampling control circuit and is adjusted and controlled through the charging current loop control circuit and the charging voltage loop control circuit, and the charging current and the charging voltage required by the storage battery pack are limited to be preset indexes. The charging current is subjected to charging current gear control and monitoring through the charging current gear switching and telemetering circuit, the storage battery pack is charged, and the storage battery pack is prevented from being damaged during charging.
