Battery pack with easy monitoring of accury of capacty information on battery shell

摘要

The present invention relates to an outdoor type battery pack for a communication base station that can supply DC power to a base station of a communication company when a power outage occurs, and more particularly, a plurality of battery cells, and first and second fixed to upper and lower ends of the battery cells, respectively. It includes an external case in which a holder and an inner space in which the first and second holders are accommodated, respectively, and a battery management device electrically connected to the battery cell to monitor the voltage, current and capacity of the battery is installed on one side In the battery pack according to the invention, a unique ID selection dial which is recessed inward to set a unique number of the battery pack is installed on the outer surface of one side of the external case, and by the operation of the unique ID selection dial, the battery management device A rotatable cover is rotatably installed on the outer surface of the outer case so that the unique ID of the pack is recognized and the unique ID selection dial is not exposed to the outside, and a lock bolt is integrally coupled to one side of the rotatable cover The lock bolt is bolted to the outer surface of the outer case. According to the present invention as described above, the user can conveniently set the unique ID of the battery pack installed outdoors by opening the rotatable cover, so that the charging/discharging state of each battery pack can be individually controlled through the manager terminal through communication from the outside. It is effective to ensure that power can be stably supplied in the event of a failure, such as a power outage, at the base station of the telecommunication company. In addition, the battery cell built in the external case is press-fitted into the inner jaw so that it can be stably maintained without shaking from external impact, so that the battery is not defective due to internal device damage due to vibration during product transportation, installation process, and operation. This has the effect of reducing the failure rate and enabling stable use for a long period of time.
