浅析低温环境下纯电动汽车续驶里程缩减的因素

动力电池作为纯电动汽车的唯一能量源,其性能直接影响整车性能.动力电池性能易受温度影响,尤其在低温环境下电池充放电能力受限,进而造成纯电动汽车里程衰减.本文以某纯电动汽车为研究对象进行常温及-7℃低温CLTC工况试验,分析常温及低温整车能量管理策略,从整车开发层面提出降低纯电动汽车低温里程衰减的措施及建议.     

Super-capacitive performances of nickel foam supported CeO2 nanoparticles

This paper designs and fabricates CeO₂ nanoparticles on a large scale by hydrolysis and oxidation of cerium carbide. The electrochemical supercapacitor behavior of CeO₂ nanoparticles was investigated. The nickel foam (NF) supported CeO₂ nanoparticles show a high areal capacitance of 119 mF/cm², demonstrating a strong synergistic effect between NF and CeO₂ nanoparticles. The high capacitance of the CeO₂/NF nanoparticles is possibly due to an improved conductivity by NF and a better utilization of CeO₂ nanoparticles.
