APPARATUS FOR LEVELING VOLTAGE FOR CONNECTING UNIT RACKS FOR STORING POWER, AND SYSTEM FOR STORING POWER COMPRISING SAME

摘要

The present disclosure describes a voltage equalization apparatus for equalizing voltages of adjacent power storage unit racks included in a power storage system. The voltage equalization apparatus according to the present disclosure includes a resistor to which a current flowing from a high-voltage unit rack to a low-voltage unit rack is applied; and a circuit breaker for voltage equalization installed on a line through which the current flows.
