Abstract
The specific heat capacity and heating power under 0.5 C discharge of the 18650 type Li-ion battery were measured.The specific heat capacity was 995 J/Kg · ℃.The heating power changed along with the state of charge (SOC).The reliability and practicability of parameters measurement method were verified through the comparison of the experimental and simulation data.The heating power of the battery under 0.5-2.0 C discharge was measured.The thermal management of the battery pack was carried out,the cooling water pipe was laid along the axial direction of the battery.It was found that the optimal parameter of water cooling under extreme conditions was 25 ℃,the flow rate was 10 cm/s through the ANSYS simulation platform.关键词
