Vehicle charging and discharging control method, device, charging and discharging system and vehicle

Abstract

The embodiments of the invention provide a vehicle charging and discharging control method, a device, a charging and discharging system and a vehicle. The control method comprises the following steps:the charging plug head type of a charging plug inserted into a fast charging socket of the vehicle is acquired; according to the charging plug head type, a state signal received by the vehicle is acquired; when the state signal meets the operating state of the charging plug head type, a wake-up signal corresponding to the charging plug head type is generated; and the wake-up signal is transmittedto a vehicle control unit (VCU), so that the VCU is electrified and controls the vehicle to get into a charging and discharging mode corresponding to the charging plug head type of the charging plug.The solution of the invention avoids the problem that the electricity consumption of a vehicle is increased because the vehicle gets to a charging and discharging wait mode as soon as a charging plugis inserted, causing the vehicle to get into a feed state to affect the service life of the vehicle, and the problem that the starting of other requirements on the vehicle is affected because the priority of the charging and discharging wait mode is overhigh, and thereby the driving experience of users is ensured.

Description

technical field [0001] The invention relates to the field of charging and discharging of vehicles, in particular to a control method and device for charging and discharging of vehicles, a charging and discharging system and a vehicle. Background technique [0002] As the main new energy vehicles, electric vehicles are more and more popular, and the charging problem of electric vehicles is an important factor affecting its development. At present, when electric vehicles are charging, they usually perform fast charging by connecting a fast charging gun to a fast charging stand, or slow charging by connecting a slow charging gun to a slow charging stand. The two charging methods need to be connected to different charging stands of the vehicle, and the two There is a set of charging systems for each charging method, which makes the design of the charging system on the vehicle side cumbersome. And the vehicle outputs a wake-up signal to the VCU (vehicle control unit, Vehicle Con...
