The invention provides a battery management system, a battery system, an electric vehicle and a charging wake-up method. The battery management system comprises a processing circuit, a charging wake-up circuit, a charging holding circuit and a functional circuit. Wherein the charging wake-up circuit is used for outputting a wake-up pulse signal according to a resistance signal generated by a charging pile and received by a charging interface; the charging holding circuit is used for outputting an enable signal according to any one of the wake-up pulse signal and the wake-up holding signal; the functional circuit and the processing circuit are both configured to be in an awakening state in response to the enable signal; and the processing circuit is further configured to continuously output a wake-up holding signal after being switched from the dormant state to the wake-up state until the charging is finished. According to the scheme, the battery management system is awakened through the awakening pulse signal, and the processing circuit can keep awakening or enter dormancy after being awakened, so that the power consumption of the battery management system is reduced.

    本申请提供一种电池管理系统、电池系统、电动交通工具及充电唤醒方法,电池管理系统包括处理电路、充电唤醒电路、充电保持电路以及功能电路;其中,充电唤醒电路用于根据充电接口接收到的由充电桩生成的电阻信号,输出唤醒脉冲信号;充电保持电路用于根据唤醒脉冲信号和唤醒保持信号中的任一信号,输出使能信号;功能电路和处理电路均配置为响应使能信号处于唤醒状态;以及,处理电路还配置为自休眠状态切换至唤醒状态后,持续输出唤醒保持信号,直至充电结束。本申请的方案,通过唤醒脉冲信号唤醒电池管理系统,处理电路在唤醒后可执行保持唤醒或进入休眠,从而降低了电池管理系统的功耗。
