Abstract
A rack BMS detects a ground fault through a circuit embedded therein, and as a master BMS is configured to disconnect all the connections between battery racks and a grid in the case in which the rack BMS detects the ground fault, no more current flows through chassis, thereby protecting the battery racks and ensuring safety of a person using the battery racks.
