今天，可以用MATLAB从头开始在笔记本电脑上设计铅酸电池的数学模型。它仍然需要时间来开发，但现在这些模型不能单独被认为是创新，因为任何人都能够用适当的工具做同样的事情。比以往任何时候，真正的创新在于对最重要问题的回答：一个模型做什么？在这里，该模型的主要目标是模拟所有车辆生命周期中的蓄电池充液行为。因此，在不同的操作条件下，用实验数据来验证它们似乎是合理的，以证明模拟结果是可靠的。它具有挑战性但可行，特别是通过正确选择参数值范围并研究它们如何影响输出。另一个目标是了解由于在各种速率和温度下涉及的物理化学过程而导致的电池行为变化，以解释Peukert定律和温度对车辆起动的影响。该模型的最终目标是找到与主要老化现象相对应的参数变化，以模拟新电池和旧电池。
Today, it is possible to design a mathematical model of lead-acid battery on a laptop from scratch with MATLAB. It still takes time to develop, but nowadays these models alone cannot be considered innovations anymore because anybody is able to do the same with the appropriate tools. More than ever, the actual innovation lies in the answer given to the most important question: a model to do what? Here, the model's main goal is to simulate the flooded battery behavior in all vehicle life cycles. Thus, it seems legitimate to validate them under different operating conditions with experimental data to prove that the simulation results are reliable. It is challenging but feasible, notably by making a correct selection of the parameter value ranges and studying how they influence the output. Another goal is to understand the battery behavior changes due to the physicochemical processes involved at various rates and temperatures to explain Peukert's law and the impact of temperature on vehicle cranking. The final objective of this model is to find parameter changes corresponding to the main aging phenomena to simulate new and also used batteries.
