The Design and Implementation of Smart Battery Management System Balance Technology

To reduce the imbalance of Smart Battery and prolong the life of Smart Battery, the smart battery management system equalization charging protection system of battery series is designed. The imbalance reason of Li-Ion battery series and common balance technology was firstly analyzed, and then the battery balance principle based on X3100 chip was analyzed, and smart battery balance control circuit and software implementation were designed. According to the test, the balance design project can implement effectively the balance function of battery, and is characterized by low cost and simple circuit. It can be used in low power consumption equipment such as laptop computer and can improve the performance of battery and prolong the life of battery series.
