摘要

电池外部特性的精确建模是储能系统中有效管理电池的一个基本问题。由于许多固有因素影响了外部特性,但只有很少的信息,如端子电压、电流和表面温度,可以获得建模的困难。本文提出了一种简单的电池放电特性建模方法。分析了放电曲线的基本形态及其与放电电流的关系。在此基础上建立了数学模型,并通过阀控铅酸蓄电池的实验对模型进行了验证。

A Battery Modeling Method and Its Verification in Discharge Curves of Lead-Acid Batteries
Modeling the external characteristics of the battery precisely is a basic issue for effective battery management in energy storage systems. It is difficult because many inherent factors influence the external characteristics, but only few information, such as terminal voltage, current and surface temperature, can be obtained for modeling. This paper proposes a simple method for modeling the discharge characteristics of the battery. The basic patterns of discharge curves and their relationship with discharge current are analyzed. A mathematic model is built based on the method .The model is verified with experiments on valve-regulated lead-acid (VRLA) batteries.
