2022 7th International Conference on Electric Vehicular Technology (ICEVT)(2022)
摘要
The battery utilization in electric vehicles needs to be operated at its operating temperature range of $20-45^{\circ}\mathrm{C}$ to hinder several issues, including a reduction of life capacity and thermal runaway. A battery thermal management system (BTMS) is based on a phase change material (PCM) and the heat pipe is harnessed to maintain the battery temperature. In this research, the BTMS by harnessing animal fat as the PCM and a heat pipe was investigated through experimental methods. Characterization material with the T-history method and thermal performance testing with three different loads of 0,5 C, 1C, and 2 C were conducted. The Findings showed that the proposed module batteries could be applied as the BTMS in electric vehicles due to their thermal properties, which had a melting temperature of 37,18°C and latent heat of 72,71°C. The proposed BTMS could reduce the temperature by 14, 7°C at the highest load of 2 C discharge rate from three discharge loads. Moreover, the temperature differences among batteries can be retained below 5°C. In conclusion, the proposed BTMS in this research has shown the ability to harness natural resources to reduce the battery temperature in electric vehicles. Thus, this can be a promising BTMS in the future.
