摘要:
针对储备式锂电池在使用前放电特性不具备可检测性,有可能导致放电失效的问题,提出了储备式锂电池锤击激活的流固耦合仿真方法。该方法将储备式锂电池的激活过程分为破瓶和进液两个过程,利用ANSYS/LS-DYNA中的流固耦合方法进行模拟,固体模型采用Lagrange算法,流体材料采用ALE算法,流固耦合方式采用ALE方法来处理相互作用。仿真与实测的对比验证表明,10 000 g过载下仿真值和实测值接近,6 000 g过载下二者差别较大,表明10 000 g及以上的激活过载有利于该模型所对应的储备式锂电池快速激活,6 000 g及以下的激活过载不利于该模型所对应的储备式锂电池快速激活。因此,可根据不同的电池模型进行不同的仿真计算,从而弥补储备式锂电池使用前放电特性不可检测的缺点,在一定程度上提高了储备式锂电池作用可靠性。
Abstract:
A fluid-solid coupling simulation method was proposed for hammering activation of the reserve lithium battery to overcome the shortcoming that the discharge of the reserve lithium batteries was undetectable which may cause failure in use. The activation process of the reserve lithium battery including two periods: the bottle break and the liquid inlet. The fluid-solid coupling method in ANSYS/LS-DYNA was used for simulation. The Lagrange algorithm was employed for solid model and the ALE algorithm was used for the liquid model and used to handle the interaction for the model of fluid-solid coupling. Comparison the simulated result with the experimental values, it showed that the simulated and measured values were close for the overload of 10000g, while there were quite different for the overload of 6000g. This indicated that the activation overload higher than 10000g was beneficial to the rapid activation of the reserve lithium battery, but the activation overload of 6000g and below was not conducive. Therefore, different simulation calculations can be performed according to different batteries, which can solve the issue that reserve lithium batteries cannot be detected before used. Moreover, the reliability of the reserve lithium battery can also be improved to some extent.
