The invention discloses a tamper-proofing method, device and equipment for lithium battery charging and a medium. The lithium battery charging tamper-proofing method is executed by a lithium battery and comprises the following steps: when detecting that a charger is electrically connected, sending first single-line data to the charger, and determining a blind charging judgment time window according to the sending time of the first single-line data; if it is identified that the charger outputs the effective current, second single-line data are sent to the charger; if it is identified that the current output by the charger in the blind charging judgment time window jumps and an authentication current code sent by the charger according to the second single line data is received, compliance verification is carried out on the authentication current code; and if it is determined that the authentication current code passes compliance verification, third single-line data are sent to the charger, and adaptive current output by the charger based on the third single-line data is received. According to the technical scheme, the charging safety of the lithium battery of the electric vehicle can be guaranteed, and the safety accident rate caused by tampering of the battery or the charger is reduced.

    本发明公开了一种锂电池充电防篡改方法、装置、设备及介质。锂电池充电防篡改方法,由锂电池执行,包括:当检测存在充电器电连接时,向充电器发送第一单线数据,并根据第一单线数据的发送时间,确定盲充判别时间窗口;若识别出充电器输出有效电流,则向充电器发送第二单线数据;若识别出充电器在盲充判别时间窗口输出的电流存在跳变,且接收到充电器根据第二单线数据发送的认证电流码,则对认证电流码进行合规性验证;若确定认证电流码通过合规性验证,则向充电器发送第三单线数据,并接收充电器基于第三单线数据输出的适配电流。本发明实施例的技术方案能够保证电动车锂电池的充电安全性,降低电池或充电器篡改导致的安全事故率。
