Abstract
The invention relates to a method and a device for supplying at least one load consumer during a mains failure. According to said method, a plurality of batteries acts as an emergency voltage source during the failure of a mains voltage source in order to supply the load consumer(s). The plurality of batteries is connected to the mains voltage source. The batteries are interconnected in series in order to form the emergency supply for the load consumer. To permit a simple, cost-effective emergency supply with a reliable charging of the batteries, the plurality of series-connected batteries is sub-divided into at least two battery groups using a splitter circuit and each of said battery groups is connected to the mains voltage source for charging purposes by means of a corresponding connection circuit.
