Temperature controlling system and method for battery

Abstract

The present invention provides a temperature controlling system for a battery in an energy storage system, the temperature controlling system including: a converter comprising a plurality of switches and a converter inductor, the converter being configured to increase or decrease a voltage of the battery; a DC linker comprising first and second capacitors that are coupled in series and configured to stabilize an output voltage of the converter; and an inverter comprising a plurality of switches and an inductor, the inverter being configured to invert an input voltage, wherein the inverter further comprises a switch coupled between a terminal of the inductor and a first node between the first and second capacitors of the DC linker to provide a current from the inductor to the battery.
