| Abstract: | The paraffin/expanded graphite composite phase change material is prepared, and its thermophysical parameters are tested. The charging and discharging test bench of phase change cooling lithium battery module is built. For a 25-parallel lithium battery module, the battery charging and discharging tests are carried out under different working conditions, such as low temperature, normal temperature and high temperature. The temperature rising curves at different measuring points of the battery module are obtained, and the uniformity of the maximum temperature and temperature distribution of the lithium battery at the end of charging under different working conditions is explored. The results show that phase change cooling has good temperature control and uniform effect on lithium battery module. |
