The invention relates to the technical field of lithium batteries, and discloses a power management method and system. The method comprises the following steps: when the battery module is connected, controlling the DCDC module to enter a power-on state; when the DCDC module is in the starting state, the state of a vehicle engine is detected, and whether a dormancy condition is met or not is judged; and when the state of the vehicle engine meets the dormancy condition, the DCDC module is controlled to enter the dormancy state from the starting state. When the DCDC module is started, the state of the vehicle engine is detected, and the DCDC module is controlled to sleep when the state of the vehicle engine meets the sleep condition, so that the purpose of reducing standby power consumption is achieved.
本发明涉及锂电池技术领域,公开了一种电源管理方法及系统。方法包括:当电池模块接入时,控制DCDC模块进入开机状态;在所述DCDC模块处于开机状态时,检测车辆发动机的状态,判断是否满足休眠条件;当所述车辆发动机的状态满足休眠条件时,控制所述DCDC模块从所述开机状态进入休眠状态。本发明通过在DCDC模块开机时,检测车辆发动机的状态,并在车辆发动机的状态满足休眠条件时控制DCDC模块休眠,从而达到降低待机功耗的目的。
