Control system and control method for uninterruptible power supply |
摘要 |
Amount of alternating current power is calculated using measuring units for alternating current voltage and alternating current. Value of direct current is calculated using the calculated alternating current power and an efficiency table. An initial life time of a battery is predicted using the calculated direct current value and a battery life time table. Life time corresponding to an actual consumed amount is repeatedly updated using a detected direct current value and an updated life time.
