UPS battery management system and control method thereof

Abstract

The present invention provides a UPS battery management system, including a micro control unit and a plurality of functional modules connected to the micro control unit. The plurality of functional modules include a first group of functional modules and a second group of functional modules. The first group of functional modules is used for battery checking, and the micro control unit is configured to control the states of the functional modules so that the UPS battery management system has the following working modes: a normal working mode, wherein the micro control unit is configured to turn on the plurality of functional modules; a sleep mode, wherein the micro control unit is configured to turn off the plurality of functional modules; and a timed check mode, wherein the micro control unit is configured to, when in the sleep mode, turn on only the first group of functional modules at regular intervals so as to check a battery. The battery management system of the present invention has well-developed functions, can continuously monitor the state of a battery, has high safety performance and low energy consumption, and is convenient to operate.
