Abstract
A method and an arrangement of in-circuit capacity testing of at least one stand-by electrical energy storage device (1; 11; 12) connected between two conductors (3, 4; 13, 14) in parallel with a DC supply, in turn supplied from a mains line, and also in parallel with a power consuming device (2) is described. A controllable current source (6) is provided that is connectable in series with the battery (1). A control device (7) controls the controllable current source (6) to maintain either a desired output current or a desired output power from the battery (1). A voltage measuring device (8) for measures the voltage across the battery (1) to determine its capacity at least during testing.
