The invention discloses an electric vehicle OBC dormancy wake-up management method which comprises the steps that S1, a power management chip identifies multiple wake-up source signals and detects whether any wake-up source signal is effective or not; s2, the power management chip judges that the wake-up source signal is valid, starts a power management module, and sends a wake-up instruction to the main MCU module; and S3, the power management chip judges that the wake-up source signal is invalid, and stops sending the wake-up instruction to the main MCU module. The invention further discloses an electric vehicle OBC dormancy awakening management system which comprises an OBC module, a power management chip, a power management module and a main MCU module. According to the invention, the independent power management chip is used as the sleep wake-up management chip of the OBC system, and the power management chip manages a plurality of wake-up sources in a centralized manner, so that the OBC system has the advantages of stable performance, low cost, system response timeliness and low power consumption.

    本发明公开了一种电动汽车OBC休眠唤醒管理方法,包括:S1:电源管理芯片识别多路唤醒源信号,并检测任意一路唤醒源信号是否有效;S2:电源管理芯片判断出唤醒源信号有效,开启电源管理模块,并向主MCU模块发送唤醒指令;S3:电源管理芯片判断出唤醒源信号无效,停止向主MCU模块发送唤醒指令。本发明还公开了一种电动汽车OBC休眠唤醒管理系统,包括OBC模块、电源管理芯片、电源管理模块和主MCU模块。本发明采用单独的电源管理芯片作为OBC系统的休眠唤醒管理芯片,电源管理芯片集中管理多个唤醒源,具有性能稳定、成本低廉、兼顾系统响应及时性和低功耗的优势。
