Abstract

A conversion power supply and an autonomous electric energy replenishment method for an energy storage system are provided. An output terminal of the power supply module is connected to a second side of a first DC-DC converter through an energy storage element. A first side of the first DC-DC converter is connected to battery clusters of the energy storage system through a DC interface of the conversion power supply, so that under control by a conversion power supply controller, in a case that a voltage of a battery cluster is lower than a preset threshold, the first DC-DC converter receives the electric energy on the second side, and transmit the electric energy to the first side of the first DC-DC converter, to realize a electric energy replenishment function for at least one of the battery clusters and prevent battery failure due to over-discharge.
