Abstract:With the rise of new energy power generation and electric vehicles, energy storage system is growing in size and number. Traditional storage management contains only data collection and charge-discharge control functions and simple SOC estimates, the function of a single rough algorithm. In this paper, based on the WINCE embedded platform, developed a set of multi-functional battery management system. The system uses a hierarchical and functional design, including data acquisition, charge and discharge control, balance control, activation control, SOC estimates, alarm and protection, data display and processing, etc. you can choose a combination of functional modules, with the versatility.
