  • Patent number: 10630087
    Abstract: The invention provides an uninterruptible power supply, which comprises a battery management circuit and a control circuit. The battery management circuit is electrically coupled to each battery of at least one battery string for measuring the voltage of each battery. When the battery strings discharge, the control circuit obtains the voltage of each battery through the battery management circuit to calculate the discharge current of each battery, and determines whether there is any measured voltage having dropped to an EOD voltage corresponding to a discharge current of a corresponding battery. When the determination result is positive, the control circuit controls the uninterruptible power system to stop the discharging of at least one battery string in which there is at least one measured voltage having dropped to an EOD voltage corresponding to a discharge current of a corresponding battery. Furthermore, a corresponding battery management apparatus is also provided.
