摘要:
为了降低电芯膨胀对电池模组结构的危害,针对传统方形电池模组抑制膨胀效果的不足性,本文提出了一种方形电芯呈H形排布的新型电池模组优化结构。首先进行了方形电芯热膨胀实验,获得了电芯温度场和膨胀位移数据,结果表明电芯顶部发热最多,产生的膨胀变形相对于初始厚度增加了0.63 mm。然后基于实验数据依次建立了电芯热膨胀模型、传统方形电池模组和新型电池模组的热膨胀模型,并分析了不同充电倍率下的膨胀。最后通过仿真分析发现新型电池模组端板膨胀力最大降低了36.2%,模组膨胀变形最大减少了21%,端板与侧板应力最大分别减少了61.5%和37.4%。本文的研究能够提高电池模组的可靠性,为电池模组设计提供了新思路和参考依据。
