<p>PROBLEM TO BE SOLVED: To vary the functional operation according to the conditions on the connection of storage batteries by detecting the conditions on the number of connected storage batteries, and others. SOLUTION: This is an uninterruptive power unit where a circuit part G1 and a plurality of storage batteries H1 and H2 are made in separate bodies. In this case, this is made such that the storage batteries H1 and H2 can be connected in parallel to the circuit part G1 by connectors 1h, 1g, 2h, and 2g. Besides, this is equipped with a discrimination circuit 34 which detects the number of connected storage batteries H1 and H2 by the signals from these connectors 1h, 1g, 2h and 2g, and a control processor 35 controls the function of a power circuit 32 by the signal from the discrimination circuit 34.</p> |
