 The experimental testing of a composite container for an electric vehicle, EV, battery module filled with either a phase change material, PCM, or a conventional battery module showed that the presence of PCM significantly reduced the temperature of the battery module during charging and discharging cycles. However, this came at the cost of decreased mechanical strength of the composite material. In order to maximize the benefits of using PCM without sacrificing structural integrity, it was recommended that a combination of PCM and a composite reinforcing material should be used.
