The Design of Smart Battery Management Systems
Aiming to the defect of expandability and reliability of Li-Ion battery of protection circuit, the multisection series connection Li-ion battery management system was designed based on X3100 chip. The hardware and software design of the system was elaborated. The system can realize the measure, management and auto-protection for various parameters and complete the calculation for tens of command parameters and realize the data exchange with HOST by SMBus. Applications show that the system is characterized by simple structure, perfect function and stable and reliable operation and can be used in the smart battery model of laptop computer, Electric bicycle and other portable equipments.
