<P>PROBLEM TO BE SOLVED: To perform a discharge test based on a constant current value. <P>SOLUTION: In a discharge test mode, a battery pack 3 supplies a load device 5 with a discharge current whose desired value is a current value covering a short to a current value required by the load device 5. In the process of switching current supply to the load device 5 to the battery pack 3 owing to an output voltage of a rectifier 1 dropping below an output voltage of the battery pack 3, if the current value of the discharge current is higher than a first current threshold based on the desired value, a DC power supply system increases the output voltage of the rectifier 1 above the output voltage of the battery pack 3. In the process of switching current supply to the load device 5 to the rectifier 1 owing to an output voltage of the rectifier 1 rising above the output voltage of the battery pack 3, if the current value of the discharge current is lower than a second current threshold based on the desired value, the DC power supply system reduces the output voltage of the rectifier 1 below the output voltage of the battery pack 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
