Abstract

The invention relates to a charging awakening method, a battery management system and a vehicle. The battery management system comprises an awakening module and a power supply management module, wherein the awakening module is used for generating awakening signals when an outer charging plug is connected with a charging interface, and the power supply management module is used for receiving the awakening signals to communicate power supply circuits of a battery module and a preset functional module in the battery management system. According to a charging awakening circuit provided by the invention, the battery management system can be automatically awakened when the outer charging plug is connected to charge the vehicle, so that the battery management system automatically enters in a normal working state from a discharging state; and the battery management system can be awakened by a user without the mode of ignition, so that the charging process is simplified, user operation is facilitated, and the user experience is promoted.

Description

technical field [0001] The present invention relates to the technical field of battery management, and in particular, to a charging wake-up method, a battery management system and a vehicle. Background technique [0002] The battery management system (Battery Management System, BMS) is a key technology in the battery management of electric vehicles. It plays an important role in managing and monitoring the state of the battery modules of electric vehicles. While monitoring the remaining capacity of the battery modules Carry out charge and discharge protection on the battery module. When the vehicle is turned off, the battery management system is in a power-off state, that is, the power management module of the battery module battery management system does not supply power to each functional module of the battery management system. Therefore, when charging the vehicle, the battery management system needs to be woken up first. Make it enter the working state, that is, the pow...
