Abstract
Despite high technology in a battery, the most popular energy storage system for uninterruptible power supply (UPS) these days is a lead–acid battery. Although lead–acid battery has high reliability and low cost, many disadvantages like frequent maintenance work, bulk size, extra expenses and limit of development. Metal–air batteries are developing technology in the battery system and enlargement and commercialization of that are not common yet. But they have extremely high energy density and power density. This study shows a realistic possibility of a metal–air battery adapted to UPS with performance requirement. Cell model, stack design, and hybrid system are developed for a new type of UPS. Especially, electrolyte isolation and hybrid system is a principal specification for better performance and feasibility. Evaluation of suggested UPS system in accord with required specification shows technical feasibility.
