Power Conditioning System for Battery Energy Storage System and Method for Controlling Power Conditioning System

摘要

The present invention provides a battery management system comprising a first power conversion unit for managing power of batteries; A second power conversion unit installed apart from the first power conversion unit; A second power converter for converting the heat generated by the first power converter and the heat generated by the second power converter into a heat to cool the inside of the first power converter and the inside of the second power converter; And A first supply fan for moving the cool air supplied from the regulator into the first power converter; A second supply fan for moving the cool air supplied from the controller to the inside of the second power converter; And a movement route of the cool air supplied by the first supply fan and a movement path of the heat generated by the first power conversion unit and a movement path of the cool air supplied by the second supply fan, And a separation unit provided between the first power conversion unit and the second power conversion unit to separate the heat transfer path generated by the first power conversion unit and the second power conversion unit, and a control method of the power management apparatus for the battery energy storage system As a result, According to the present invention, by reducing the power consumption, the use time of the batteries installed in the battery management apparatus can be increased and the installation capacity of the batteries installed in the battery management apparatus can be reduced, thereby contributing to the reduction of the material cost and the operating cost.
