V2L control method and system of electric vehicle and storage medium

Abstract

The invention discloses a V2L control method and system of an electric vehicle and a storage medium. The control method comprises the steps that gear information of the electric vehicle, discharge gun connection state information, discharge switch state information, high-voltage loop fault information and discharge cut-off information are obtained, and it is determined that the electric vehicle is in a neutral position state currently, a discharge gun is in a complete connection state and a discharge switch is pressed down according to the gear information, the discharge gun connection state information, the discharge switch state information and the high-voltage loop fault information; when the high-voltage loop has no fault and the SOC of the power battery meets the discharge enabling condition, the electric vehicle is allowed to be in high voltage, and the electronic lock is controlled to work; and when the electronic lock locks the discharging connection device, a discharging work instruction is sent to the vehicle-mounted bidirectional charger, and power utilization power output is carried out on the power utilization equipment. Therefore, external discharging of the electric vehicle can be safely carried out, and external discharging can be automatically stopped in a certain remaining driving range, so that the problem of mileage anxiety when a user uses the external discharging function of the electric vehicle is effectively solved, and meanwhile, the external discharging safety of the electric vehicle is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, and in particular, to a V2L control method for an electric vehicle, a computer-readable storage medium, and a V2L control system for an electric vehicle. Background technique [0002] The V2L (supplying electric energy to the load) technology of electric vehicles, in the process of electric vehicles discharging to the outside, there is a safety problem that the vehicle starts by mistake. At the same time, it is impossible to accurately control the remaining power of the electric vehicle, which leads to the problem of insufficient cruising range of the vehicle. Affect the user's driving experience. SUMMARY OF THE INVENTION [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the first object of the present invention is to propose a V2L control method for electric vehicles, which can safely discharg...

Problems solved by technology

[0002] The V2L (providing electric energy to the load) technology of electric vehicles has the safety problem of false start of the vehicle during the discharge process of the electric vehicle. At the same time, the remaining power of the electric vehicle cannot be accurately controlled, which leads to the problem that the vehicle is prone to insufficient cruising range. Affect the user's driving experience
