Battery pack construction scheme based on ups system reliability

Abstract

As an important part of the UPS system, the performance of the battery pack has a direct impact on the reliability, security, and safety of the whole system. Therefore, in recent years, the research on the feasibility of supporting battery selection for UPS system operating environment and performance requirements has been gradually expanded and deepened, to achieve UPS uninterrupted power supply and cost reduction. By comparing the performance of acid-proof exhaust type battery and valve-controlled lead-acid battery, this paper introduces the selection principle of the battery pack and expounds the reason why the UPS power system chooses valve-controlled lead-acid battery. An example is given to illustrate how to calculate battery capacity and its selection and configuration, the influence of environmental temperature and safety factor on the calculation result of battery capacity is discussed, and the optimization method of battery capacity calculation and selection for UPS power supply system is put forward.
