Electrochemical device management method, charging device, battery system, and electronic apparatus

The embodiment of the invention provides an electrochemical device management method, a charging device, a battery system and electronic equipment. The electrochemical device management method comprises the following steps: determining the lithium precipitation degree of an electrochemical device; in response to the degree of lithium precipitation of the electrochemical device being greater than the first degree of lithium precipitation threshold, charging of the electrochemical device is limited. According to the electrochemical device management method, the electrochemical device can be reasonably managed, the influence of lithium precipitation on the safety and the service life of the electrochemical device is effectively reduced, and the efficiency of the electrochemical device is improved. 本公开实施例提供了一种电化学装置管理方法、充电装置、电池系统及电子设备，该电化学装置管理方法包括：确定电化学装置的析锂程度；响应于电化学装置的析锂程度大于第一析锂程度阈值，限制对电化学装置的充电。该电化学装置管理方法能够合理地对电化学装置进行管理，有效地降低析锂对电化学装置的安全和寿命的影响，提高电化学装置的效能。
