Abstract
The battery thermal management technology is vital for the development of new energy vehicles. In order to understand the performance of the phase change material/heat pipes (PCM/HP) coupled thermal management system for cylindrical power battery, an PCM/HP coupled BTM module was designed and tested experimentally in detail. The results showed that the effect of temperature control based on PCM is improved comparing to air-based BTM under natural convection. The maximum temperature of PCM/HP coupled BTM can be controlled below 50 °C for longer time than those of the air-based case and PCM-based case under the same conditions. The temperature difference can be reduced about 33.6% through filling PCM and it can progress a decline of 28.9% further through embedding HP into the PCM. The maximum temperature difference of PCM/HP coupled BTM can be controlled below 5 °C for longer time than those of the two other cases, air-based BTM and PCM-based BTM. It is almost the same in the first 620 s under different velocities, which are all less than 5 °C.
