论文摘要
混合储能系统（HESS）在行业中雕刻了一个利基市场。 HESS提高系统效率，降低整体成本并提高系统的寿命。质子交换膜（PEM）燃料电池与锂离子电池（LIB）杂交，用于车辆应用，机器人应用等，在具有几何空间限制的应用中，储能元件的温度受对流传热的影响。在本文中，使用comsol多物理软件软件包对PEM-LIB混合系统的几何形状进行热分析，以用于LIB的不同放电速率（C速率）和PEM电池的不同电压。当与PEM电池近距离接近时，LIB包装的温度额外升高在4C时在0.03-0.6 $^0 $ C的范围内。 LIB包装的细胞温度随着C速率的增加和PEM细胞电压的降低而升高。
Hybrid energy storage systems (HESS) have carved a niche in the industry. HESS improve the system efficiency, reduce the overall cost and increase the lifespan of the system. The proton exchange membrane (PEM) fuel cell is hybridized with Li-ion batteries (LIB) for vehicular applications, robotic applications etc. In applications which have geometrical space constraints, the temperature of the energy storage elements is influenced by convective heat transfer. In this paper the thermal analysis of the geometry of PEM-LIB hybrid system is carried out using COMSOL Multiphysics Software package for different discharge rates (C rates) of the LIB and different voltages of the PEM cell. The additional rise in temperature of the LIB pack when placed in close proximity with PEM cell was in the range of 0.03-0.6$^0$C at 4C. The cell temperature of the LIB pack increased with increase in C rate and decrease in PEM cell voltage.
