Lithium ion battery safety management system and method

The invention belongs to the technical field of lithium batteries, and particularly relates to a lithium ion battery safety management system and method. The system comprises a charger console and a master control disconnection module, and further comprises a thermal runaway information acquisition module and/or a battery information storage module. According to the lithium battery charging circuit, the main control disconnection module is arranged in the lithium battery charging circuit, so that the lithium battery is locked under the condition of determining that the lithium battery is not an original battery or the battery is aged, the possibility of spontaneous combustion caused by recharging is cut off, and the safety of the lithium battery is ensured. 本发明属于锂电池技术领域，具体涉及一种锂离子电池安全管理系统及方法。该系统包括充电器控制台和主控断开模块，还包括热失控信息采集模块和/或电池信息存储模块。本发明通过在锂电池充电电路中设置主控断开模块，以在确定锂电池非原装电池或者电池出现老化的情况下对锂电池进行锁定，断绝再次充电导致自燃的可能，保证了锂电池的安全。
