Method, battery management system and vehicle for charging awakening

摘要

The present invention relates to a method, a battery management system and a vehicle for charging awakening. The battery management system includes a wake-up module, used for generating a wake-up signal when the battery management system is in a dormant or power-off state and an external charging plug is connected with a charging interface; and a power management module, used for conducting a power supply circuit between a battery module and a preset function module in the battery management system when receiving the wake-up signal. According to the system for charging wake-up provided by the present invention, the battery management system is automatically woken up when the external charging plug is accessed to charge the vehicle, so the battery management system automatically enters a normal working state from the power-off state or the dormant state.
