As an excellent choice of energy storage, batteries have been integrated into not only a wide range of industrial applications, but also everyone’s everyday life. At the moment, Li-ion batteries are dominating the market with regard to many applications, as well as in research areas. However, because of the concerns including safety issues, the possible shortage of Li and so on, more and more people are starting to look for an alternative of Li-ion batteries. Zinc-air batteries, with their high specific energy and advantages over safety and cost, are considered one of the most promising next-generation batteries. However, to the best of our knowledge there is yet no developed model that is satisfactory with regard to describing the electrical behavior of commercial zinc-air battery cells precisely. This work focuses on developing an equivalent circuit model for zinc-air batteries that is able to reconstruct the dynamic electrical behavior of the cells taking dependence of state of charge (SOC), current and temperature into account. The modeling and parameterization is conducted in time domain, where the parameterized model is simulated in MATLAB/ Simulink for validation. Through the modeling procedure, a full parameter set is acquired for the studied zinc-air battery cell, enabling modeling and further analysis of parameter changes. Validation results show that the parameterized model is able to reconstruct the relaxation behavior accurately. Meanwhile, larger errors occur regarding discharging behavior, which is possibly caused by
lack of excitation during the characterization tests.
