摘要
水下航行器能否顺利的完成指定的任务,达到设计的航程、航速,依赖于其中高效的动力电池,因而建立合理的电池模型对于研究动力电池的性能,保证水下航行器的运作而言有着非常重要的意义.本文根据锂离子电池的特性,从电池电化学角度分析,建立了电池的等效电路模型.通过实验方法对电池模型中的各个参数进行了辨识,并与实验数据进行了对比,验证了所建模型的可靠性.
If the underwater vehicle can successfully complete the assigned task to reach the designed voyage and speed is rely on its high-efficiency power battery. So establish a reasona- ble battery model means a lot to the study of performance of the power battery and the oper- ation of underwater vehicle. According to the character of lithium ion battery, a equivalent circuit model which is analysis from the electrochemistry of the battery has been established. Identify each parameter of the model and compare with the experimental data to verify the reliability of the model.
