The invention provides a double-lithium battery management system and a control method. The system comprises a first lithium battery BMS, a second lithium battery BMS and a lithium battery charger. Based on the system, the invention provides a double-lithium-battery system management method, and particularly describes methods and steps of lithium battery state management, discharging host management, charging host management, host handover command processing and the like in a double-lithium-battery management process. Through the CAN bus and the double-lithium-battery system management method, multiple functions such as double-lithium-battery discharging switching, double-lithium-battery charging switching and double-lithium-battery charging and discharging management are achieved, the defect that an electric bicycle in the current market is short in endurance mileage is overcome, and meanwhile intelligent, automatic and safe management of the double-lithium-battery system is improved.

    本发明提供的一种双锂电池管理系统及控制方法,系统包括:第一锂电池BMS、第二锂电池BMS和锂电池充电器。基于这个系统,本发明提出了一种双锂电池系统管理方法,具体描述了双锂电池管理过程中的锂电池状态管理、放电主机管理、充电主机管理和主机交接命令处理等方法和步骤。本发明通过CAN总线和双锂电池系统管理方法,实现了双锂电池放电切换、双锂电池充电切换以及双锂电池充放电管理等多种功能,改善了目前市面上电动自行车续航里程短的缺点,同时提升了双锂电池系统的智能化、自动化和安全性的管理。
