Abstract
The present invention relates to an apparatus, a system, and a method of preventing a battery rack from being damaged by measuring a current, which, when a battery module is abnormally connected with a relay in some battery racks in installing the relay, which conducts or blocks a current flowing in the battery rack including a plurality of battery modules so that a current exceeding a predetermined current limit value flows in the battery rack, prevent a short-circuit phenomenon, by controlling an operation state of the relay before the battery rack and the relay form a short circuit, and prevent capacitance imbalance between the battery racks by controlling an operation state of the relay when a voltage difference between a plurality of battery racks exceeds a predetermined voltage difference.
