An accurate estimation technique of the state of charge (SOC) of batteries is an essential task of the battery management system. The adaptive Kalman filter (AEKF) has been used as an obsever to investigate the SOC estimation effectiveness. Therefore, The SOC is a reflexion of the chemistry of the cell which it is the key parameter for the battery management system. It is very complex to monitor the SOC and control the internal states of the cell. Three battery models are proposed and their state space models have been established, their parameters were identified by applying the least square method. However, the SOC estimation accuracy of the battery depends on the model and the efficiency of the algorithm. In this paper, AEKF technique is presented to estimate the SOC of Lead acid battery. The experimental data is used to identify the parameters of the three models and used to build different open circuit voltage–state of charge (OCV-SOC) functions relationship. The results shows that the SOC estimation based-model which has been built by hight order RC model can effectively limit the error, hence guaranty the accuracy and robustness.

In the charge and discharge system of lead-acid battery, in order to ensure the normal operation of charge and discharge, and to prolong the service life of lead-acid battery, battery management system (BMS) must be built up for lead-acid battery. The battery management system detects each index of battery to prevent over charge and over discharge appeared. In this paper, the function of battery management system, detection of battery voltage and battery current are researched. The lead-acid battery management system is designed to achieve the purpose of real-time monitoring of the lead-acid battery.
