The invention discloses a lithium battery safe charging and discharging control method and system, and relates to the technical field of lithium battery application, and the method comprises the following steps: S1, detecting the initial state of a lithium battery: detecting the initial state of the lithium battery, obtaining the initial state value of the lithium battery, judging whether the lithium battery is suitable for charging and discharging operation according to the detection result, and if yes, executing the step S2; if an abnormal condition exists, alarming and stopping charging and discharging are carried out; and S2, charging stage control. According to the lithium battery safe charging and discharging control method and system, the rate and mode of the charging and discharging process of the lithium battery can be accurately managed through the hierarchical module, instant overlarge current or voltage is avoided, the risk of safety accidents is reduced, the whole lithium battery charging and discharging process can be better controlled and stabilized by gradually increasing or reducing the discharging rate, and the safety of the lithium battery is improved. And charging and discharging are adjusted according to the state and requirements of the lithium battery, so that the energy output and input of the lithium battery can be maximized, and the service life of the lithium battery is prolonged.

    本发明公开了一种锂电池安全充放电控制方法及系统,涉及锂电池应用技术领域,包括以下步骤:S1、检测锂电池的初始状态:对锂电池的初始状态进行检测,并获得锂电池初始状态数值,根据检测结果,判断锂电池是否适合进行充放电操作,若存在异常情况,则进行报警并停止充放电;S2、充电阶段控制。该锂电池安全充放电控制方法及系统,通过分阶模块,可以精确管理锂电池的充放电过程的速率和方式,避免电流或电压的瞬间过大,降低安全事故发生的风险,通过逐步增加或减少放电速率,可以更好地控制并稳定整个锂电池充放电过程,并根据锂电池的状态和需要,调整充放电,可以最大化锂电池的能量输出与输入并延长其使用寿命。
