论文摘要
尽管在典型的标准化测试中，电池几乎只充满恒定电流或相对缓慢变化的周期，但实际应用涉及快速负载波纹，这不会有助于净能量。降低过滤器电容器甚至动态重新配置的电池的趋势进一步增加了波纹。因此，波纹载荷对锂电池的影响引起了人们的注意。根据最近的研究，加速的衰老很大程度上取决于纹波的频率。我们使用电化学模型来得出高度简化的回归模型，该模型捕获渐近行为并允许对特定细胞的参数识别和校准。该模型允许对电池管理系统中的波纹电流引起的其他老化进行定量监视。此外，它通过影响现代电池系统（例如可重构电池）中的频率内容来积极控制衰老潜力。
Whereas in typical standardized tests batteries are almost exclusively loaded with constant current or relatively slowly changing cycles, real applications involve rapid load ripple, which do not contribute to the net energy. The trend to reduced filter capacitors and even dynamically reconfigurable batteries further increases the ripple. The influence of rippled load on lithium batteries is therefore receiving increased attention. According to recent studies, accelerated ageing strongly depends on the frequency of the ripple. We use electrochemical models to derive a highly simplified regression model that catches the asymptotic behavior and allows parameter identification and calibration to specific cells. The model allows quantitative monitoring of the additional ageing due to ripple current in battery management systems. Furthermore it enables active control of the ageing potential by influencing the frequency content in modern battery systems, such as reconfigurable batteries.
