摘要
介绍了全钒液流电池(VRB)的化学反应原理以及组成部分,分析并确定影响钒电池充放电的主要因素,建立了2.5kW钒电池的电化学模型和机械模型。利用Matlab仿真,在恒流充放电的条件下,得到钒电池运行过程中的电堆电压和电池功率曲线,研究了电池充放电过程中的流量参数优化。该模型较好地反映了钒电池的充放电特性,可为钒电池的操作运行以及能量优化提供工程指导。
The chemical reaction and components of the VRB was introduced, the main affecting factors were analyzed and determined, and the model of the 2.5 kW VRB was built, which composed the electrochemical model and mechanical model. The model was simulated by the toolbox of Matlab with constant current, the stack voltage and power curve of the VRB was obtained, and the optimization of the flowrate parameters was studied during the charge and discharge. The model could reflect the characters of the VRB in charge and discharge process, which provided an engineering guidance for the operation and energy optimization of VRB.
