Abstract

The invention relates to the technical field of uninterruptible power supplies and particularly to a charging control method for an uninterruptible power supply (UPS). The method, by decreasing the charging current of the UPS when input voltage decreases and increasing the charging current of the UPS when the input voltage increases, enables the voltage of the UPS being constant and not to exceed the rated operating voltage of the UPS when the voltage of the UPS is lower than the rated input voltage of the UPS, thereby reducing the specification requirements of wires, material volume, and product cost.

Description

technical field [0001] The invention relates to the technical field of uninterruptible power supplies, in particular to a charging control method for uninterruptible power supplies. Background technique [0002] The charging methods for batteries in traditional uninterruptible power supply (UPS) systems mainly include: [0003] 1. Constant current charging method, suitable for charging with low current for a long time. This method is beneficial to the charging of UPS batteries with slow capacity recovery. The disadvantages are that the initial charging current is too small, and the charging current is too large in the later stage of charging, the charging time is long, the gas is released, the impact on the plate is large, and the energy consumption is high. , Low efficiency. [0004] 2. Constant voltage charging method, which is widely used for supplementary charging. Because the initial charging current is too large, when charging a UPS battery with an excessively deep ...
