Abstract

The embodiment of the application provides a vehicle charging control method, device and system, and a storage medium. The vehicle charging control method comprises the steps of receiving a charging gun connection signal, determining the working state of a power control system of a vehicle, sending a charging start signal to a BMS of the vehicle if the power control system does not work so that the BMS controls a storage battery of the vehicle to receive the electrical energy output by a charging gun, and sending a charging fault signal to the BMS if the power control system works so that theBMS controls the storage battery to stop receiving the electrical energy. The situation that the vehicle is charged during running causes many potential safety hazards, so after determining that the connection of the charging gun is normal, it is still necessary to continue to determine that the power control system of the vehicle does not work before controlling charging. Therefore, the safety hazards in the charging process can be reduced by avoiding the situation that the vehicle is charged in a running state, and the safety of the charging process is improved.

Description

technical field [0001] The present application relates to the technical field of vehicle control, in particular, to a method, device, system and storage medium for controlling vehicle charging. Background technique [0002] In the prior art, after the vehicle is connected to the charging gun, the BMS (Battery Management System, battery management system) detects that the battery of the vehicle is normal and the connection of the charging gun is also normal, and the BMS will control the battery to start receiving the electric energy output by the charging gun. to charge the battery. However, while charging the battery, the control logic of the BMS is relatively simple, so there are many safety hazards in the charging process. Contents of the invention [0003] The purpose of the present application is to provide a control method, device, system and storage medium for vehicle charging, so as to effectively reduce potential safety hazards in the charging process. [0004] I...
