Abstract

The invention relates to the technical field of battery charging control, particularly provides a charging awakening method and device of a vehicle BMS and a vehicle charging system, and aims to solvethe technical problem of how to reliably charge and awaken the vehicle BMS. For this purpose, according to a charging awakening method of a vehicle BMS in an embodiment of the invention, charging control instruction of a vehicle BMS, which is generated according to a vehicle charging intention and is obtained based on a wireless communication technology, can be obtained; and a BMS wake-up instruction is generated according to the charging control instruction, and a preset low-voltage power supply is controlled to output a wake-up signal to the BMS based on a wireless communication technologyaccording to the BMS wake-up instruction so as to wake up the BMS. By means of the steps, the problem that in the prior art, when the BMS is awakened through a wired signal source, the BMS cannot benormally awakened due to damage of the signal cable is solved, and the awakening reliability of the vehicle BMS is improved.

Description

technical field [0001] The invention relates to the technical field of battery charging control, in particular to a charging wake-up method and device for a vehicle BMS and a vehicle charging system. Background technique [0002] During the charging process of electric vehicles, the battery management system (Battery Management System, BMS) needs to monitor the charging status of the power battery to determine whether the power battery is overheated or overcharged. When an electric vehicle is connected to a charging device such as a charging pile, the charging device will send a BMS wake-up signal to the electric vehicle through a dedicated signal cable. Provide power to the BMS to ensure the normal operation of the BMS. However, setting the above-mentioned signal cable and low-voltage power supply dedicated to BMS wake-up / power supply control on the charging device will not only increase the design / manufacturing cost of the charging device, but the signal cable is also eas...
