APPARATUS, SYSTEM AND METHOD FOR PREVENTING DAMAGE TO BATTERY RACK BY MEANS OF VOLTAGE MEASUREMENT

The present invention relates to an apparatus, a system, and a method of preventing a battery rack from being damaged by measuring a current, and more particularly, provides 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 that occurs in the battery rack when the relay is abnormally installed, 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, thereby preventing the battery rack, a battery protection unit (BPU), and an electronic component from being damaged.
