锂离子电池模型在一系列充电和排放操作后估算其能量含量,在基于电池的系统的最佳设计,分析和操作中至关重要。电池制造商提供的规格(规格)。 2007年。但是,该模型有几个缺点,包括高C率的低忠诚度,以及它没有对电池管理系统进行建模的事实。 - 基于更高的保真度,我们执行两种类型的验证,第一个使用了规格中的电压轮廓,而另一个是基于实验室实验的。我们已公开发布的模型在广泛的C率范围内公开发布,其平均绝对电压误差小于0.1 V。
Lithium-ion battery models that estimate their energy content after a series of charge and discharge operations are essential in the optimal design, analysis, and operation of battery-based systems. We focus on the class of battery models that can be calibrated entirely from the batteries manufacturer-provided specifications (spec). Such models are simple to calibrate and are therefore widely used in practice. The best-known model in this category was proposed by Tremblay et al. in 2007. This model, however, has several shortcomings, including low fidelity at high C-rates, and the fact that it does not model the battery management system. We propose an alternative, called the Power-based Integrated model that is also completely spec-based, yet has much higher fidelity. We perform two types of validation, the first one uses the voltage profiles in the spec while the other is based on laboratory experiments. Both validations confirm that our model, which we have publicly released as a Simulink system block, has a mean absolute voltage error of less than 0.1 V across a wide range of C-rates.
