The invention relates to a charging system and method of a lithium battery, the charging system comprises a charging device and a lithium battery pack, a charging loop and a communication loop are established between the charging device and the lithium battery pack, the lithium battery pack comprises a battery core group and a battery management system (BMS), the battery management system receives the state of the battery core group, generates a charging command after judgment, and sends the charging command to the charging device through the communication loop, so that the charging device outputs the charging power supply with the corresponding size according to the charging command, and charges the lithium battery pack through the charging loop; therefore, the battery management system (BMS) can dominantly control the charging operation and select better charging current according to the instant condition of the battery core group, so that the battery core group can efficiently and safely complete the charging operation.

    本发明为一种锂电池的充电系统及方法,该充电系统包含一充电装置及一锂电池组,在该充电装置与该锂电池组之间系建立一充电回路及一通讯回路,其中该锂电池组中包含一电池芯组及一电池管理系统(BMS),该电池管理系统接收该电池芯组的状态,并判断后产生一充电命令,经由该通讯回路发送该充电命令给该充电装置,令该充电装置根据该充电命令输出对应大小的该充电电源,经由该充电回路对该锂电池组充电;借此,该电池管理系统(BMS)能主导控制充电作业,根据电池芯组的即时情况,选择较佳的充电电流,令电池芯组能够有效率且安全地完成充电作业。
