Abstract

The invention relates to a UPS (Uninterrupted Power Supply) system and a UPS system intelligence charging-discharging circuit thereof, which are used for providing electrical energy conversion in the UPS system so as to realize charging and discharging of storage batteries in the UPS system. The UPS system comprises a direct-current power supply, a controller, a communication unit, a plurality of storage batteries and a load; the inner part of the controller comprises a DSP (Digital Signal Processor) module, an anode busbar, a cathode busbar and an electric energy monitoring module; the electric energy monitoring module comprises the UPS system intelligence charging-discharging circuit, a drive circuit, a current sampling module and a voltage sampling module. The UPS system is characterized in that the UPS system intelligence charging-discharging circuit is provided with an anode connecting terminal, an energy storage terminal, an adjusting terminal and a short connected terminal; the UPS system intelligence charging-discharging circuit comprises a capacitor C1, switch tubes Q1 and Q2, and an inductor L1. The UPS system and the UPS system intelligence charging-discharging circuit thereof enable multiple groups of storage batteries in different specifications in the UPS system to charge and discharge at the same time, so that abnormal storage batteries are prevented from influencing charging and discharging of other storage batteries.

Description

technical field [0001] The invention relates to the field of UPS charging circuits, in particular to a UPS system and an intelligent charging and discharging circuit for the UPS system. Background technique [0002] In the application of high-power UPS system, in order to ensure the continuous supply of stable power supply when the mains power is abnormal, the backup time is generally longer, which means more battery packs. In the entire power system, the cost of the battery part is often several times that of the UPS power supply, accounting for most of the system cost. In the design specifications for the installation of communication power supply equipment, there are clear requirements for battery packs: battery packs from different manufacturers, different capacities, different models, and different periods are strictly prohibited from being used in parallel, because when multiple battery packs are charged in parallel, if any battery pack If the body is abnormal, the vo...
