For over a decade now, the electrocaloric effect (ECE) and likewise electrocaloric (EC) cooling has been the subject of increasing research activities. Research on electrocaloric materials (ECM) is quite advanced, however, significant progress on EC cooling systems is still missing. Therefore, a methodological approach for the structured development of EC cooling systems is presented. It is based on the well‐known V‐Modell and integrates different tools, as a classification of device types, influencing factors and numerical simulation methods. The methodology can be used to structure development processes and to identify favorable geometrical and operational parameters of an EC cooling device. The methodology has been validated with a demonstrator, which was designed, built and practically tested for over 2000 hours. With this small‐scale device and a low electrical field strength of 3 kVmm‐1 a temperature span of over 1.1 K could be achieved.
