Abstract

The invention provides a UPS lithium battery integrated power supply system. The system comprises a lithium battery pack, a battery management system (BMS) module and a UPS module. The lithium batterypack is in circuit connection with the battery management system (BMS) module; the UPS module comprises a UPS-MCU controller, a charger, a filter and a rectifier. The filter comprises an inductor L1and an inductor L2. The rectifier comprises an MOS tube K2, an MOS tube K3, an MOS tube K4, an MOS tube K5, a diode D4, a diode D5, a capacitor C1 and a capacitor C2. The MOS transistors K2, K3, K4 and K5 and thyristors V1, V2 and V3 are controlled by the UPS-MCU controller, and the UPS-MCU controller can communicate with the battery management system (BMS) module. According to the invention, theproblems of incompatible communication between the UPS and the lithium battery pack, inconsistent hardware interfaces and unmatched strategies in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a UPS lithium battery integrated power supply system. Background technique [0002] Sudden power failure of certain key equipment in industries such as banks, hospitals, military, and power systems will cause heavy losses, so it is particularly important to ensure that these key equipment have a reliable and stable power supply. At present, the combination of uninterruptible power supply UPS and lithium battery provides protection for these key devices; when there is mains access, the UPS will supply the mains voltage to the load and charge the lithium battery pack at the same time; When the power is interrupted (accidental power outage), the UPS can continue to supply 220V AC power to the load through the DC power supply of the lithium battery through the inverter switching method, so that the load can maintain normal operation and protect the load software and hardware f...
