Currently battery recycling prices, several commonly used modeling methods are: First, the equivalent circuit model, a simplified model is about different battery electric components (resistors, capacitors, voltage source, etc.) by an equivalent circuit by changing the electrical parameters of components analog implementation battery charge and discharge characteristics of the work; the second is an electrochemical model, which uses a complex nonlinear equations to describe the chemical processes occurring in the battery; the third is the analysis model of the old battery recycling, namely the use of empirical equations or mathematical method to predict battery characteristics; four senior algorithm model, the upcoming battery as a "black box", using advanced algorithms (neural networks, Kalman filtering, support vector machines, etc.) on the electrical characteristics of the external battery for analysis, calculation, and then simulate the battery charge and discharge operating characteristics. Now briefly describes the characteristics of the several modeling methods, applications and so on. Open circuit voltage applied to the battery SOC test in a steady state, usually as a supplemental other algorithms. Battery recycling complex impedance measurement, in the practical application difficult. An obvious when the law is the most direct and simple, high precision battery recycling, but it is easy to have a greater cumulative error when working long hours and difficult to determine the initial SOC. Currently, the law is the practical application of safety when the most common method, and often in combination with other estimation methods, such as when Ann - open circuit voltage, ampere -Peukert equation method, when Ann -KF. Although the combination of these algorithms have not yet mature, and some complex algorithms in the SCM system is still difficult to achieve, but with the development of power electronics and computer skills, and its development has broad application prospects.
