UNIT RACK FOR POWER STORAGE, AND POWER STORAGE DEVICE COMPRISING SAME

摘要

The present invention provides a unit rack for power storage which, by means of the series or parallel connection thereof, can be used to form a power storage device having a desired capacity. The unit rack for power storage according to the present invention comprises: a plurality of cell modules which are connected to one another in series or in parallel by means of connection lines; a housing for accommodating the cell modules; a circuit breaker storage unit which is formed or installed in the housing and has a higher ground clearance than the maximum ground clearance of the cell modules; a circuit breaker which is accommodated inside the circuit breaker storage unit and is connected between the connection lines; and a storage unit cover which seals the circuit breaker storage unit. Thus, by using the circuit breaker which is installed in the unit rack for power storage which forms a power storage device, even if flooding occurs where a high capacity power storage device is installed, a low voltage state can be established, thus improving the safety of the power storage device.
