Phase Change Material Composite Battery Module for Thermal Protection of Electric Vehicles: An Experimental Observation

A composite container for an electric vehicle (EV) battery module filled with a phase-change material (PCM) was experimentally tested at various discharge rates. The average cell temperatures 1 C, 2 and 4 C rates, respectively, might reach 38 °C, 50 70 °C in the absence of any heat-absorbing material. temperature noticeably lower PCM present than conventional module. For instance, none cells inside PCM-filled were able to °C. Unfortunately, addition also degraded composite’s tensile qualities. Further investigations used Paraffin-20 Caprylone since PCMs provide notably different thermal performance due their distinctive latent heat profiles. It observed that high melting paraffin mixture, despite its slightly capacity compared Caprylone, could lead more uniform temperature. Overall, both can be as passive protection against potential abuses EV modules, while terms mechanical strength, use reinforcement is strongly encouraged.
