<jats:title>Abstract</jats:title>
<jats:p>The present simulation work discusses the effect of different electric pulses, operating temperatures, electrodes and substrate materials on electrocaloric(EC) performance. The electrocaloric effect (ECE) is analyzed using poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) P(VDF-TrFE-CFE) polymer with electrode. The P(VDF-TrFE-CFE) film (100 <jats:italic>μ</jats:italic>m) shows an effective adiabatic temperature change (Δ<jats:italic>T</jats:italic>
<jats:sub>ad</jats:sub>)<jats:sub>effective</jats:sub> (considering losses) of 4.01 K at 100 MV m<jats:sup>−1</jats:sup> when a square electric field (<jats:italic>E</jats:italic>) pulse is used. An effect of electrode and substrate layer thickness is also analyzed; the electrocaloric performance decreases with an increase in the thickness of the substrate layer. A smartphone battery’s surface (7 cm × 3 cm) is considered for cooling by the proposed design. The simulation study shows battery’s surface/source temperature dropped from 313.15 K to ∼298 K, ∼297.5 K, and ∼293.5 K when air cooling, the EC device in contact with the battery (no ECE, <jats:italic>E</jats:italic> = 0) and EC device in contact with battery (with ECE, <jats:italic>E</jats:italic> = 100 MV m<jats:sup>−1</jats:sup>), respectively are used in ∼6.5 s. The proposed EC device design can provide new insight for mobile or other electronic cooling applications.</jats:p>
