摘要
建立了锂电池充放电模型,并在Matlab上形成锂电池模型库,改变关键参数,分析锂电池中各参数对充放电曲线的影响,通过调整锂电池模型中的关键参数提高模型精度。最后,以天康TKLD-48 V/52 Ah系列锂电池实际充放电数据为例,将仿真曲线与实际充放电曲线对比,计算出模型的绝对误差小于3%,符合需求。
Lithium battery charge and discharge model was established. Lithium battery model libraries based on Matlab was established. The key parameters were changed to analyze the influence of each parameter on the lithium battery charge and discharge curve. The key parameters were adjusted to improve the accuracy of model. Finally,taking TianKang TKLD-48 V/52 Ah series of lithium battery as example, by contrasting simulation curve with the actual curve, after calculation, the model of absolute error is less than 3%. The result of simulation precision is up to the requirement.
