Discussion on the Relationship between UPS Battery Connection Method and Its Reliability

This paper deals with the field of electrical engineering and automation, mainly for the mains part of electrical engineering. On the basis of the existing UPS, the reliability of the battery in the connection method is improved. The general idea is that on the basis of the original UPS battery connection method, the series-parallel structure of the battery is improved, so its reliability and economy are enhanced. In this paper, the reliability calculation method under normal series and parallel connection method is analyzed firstly, and then the theory is linked with the actual situation. The reliability of the UPS battery part is calculated and compared under different connection methods. The optimal connection method is selected. The development of UPS is being provided with new directions and ideas. UPS is made more reliable and more economical.
