This invention relates to a base station supply management device and a method for a mobile communication system, which installs supply switches in the functional modules and automatically controller by a base station control unit, which can monitor the supply of the main power and residual capacitance parameters of stand-by batteries and sends out control orders to turn off related modules according to the supply management algorithm. This invented device and method can prolong the working time of the base station stand-by batteries when fault happens to the main power to secure the receive and forward service of data streams of the ATM interface not influencing accessing RNV of the successive base stations in the way of chain networking and other cascade networking.
