Abstract: One embodiment discloses a DC-DC converter which, in a solar-related energy storage system, cuts-off the over-discharging of a battery, and a control method thereof. Specifically, disclosed are a DC-DC converter which protects a battery by appropriately switching between a sleep mode which minimizes battery consumption by maintaining only minimized functions and a cut-off mode which prevents the battery from over-discharging by physically cutting off a circuit connected to the battery, and a control method thereof.

Abstract: The present invention relates to an apparatus for setting a communication ID of an energy storage system, the apparatus comprising: a power converter for selecting one power line from among a plurality of power lines to supply power through the selected power line; and battery managers which are sequentially connected to the power converter and are operated by the power selectively supplied through the one power line selected from among the plurality of power lines, wherein the power converter may communicate with one battery manager which is operated by the supplied power from among the battery managers.
