Electric vehicle reservation charging control method and system

Abstract

The invention discloses an electric vehicle reservation charging control method and system. The electric vehicle reservation charging control method includes the steps that an Internet-of-vehicles service platform receives a reservation charging request sent by a user through a mobile terminal or a vehicle-mounted MP5 and sends the reservation charging request to a T-Box, and the reservation charging request carries charging reservation time; after receiving the reservation charging request, the T-Box outputs a reservation charging request flag bit to a vehicle-mounted charger; the car charger judges whether reservation charging is successful or not after receiving the reservation charging request flag bit, and if reservation charging is successful, the car charger feeds back a reservation successful status to the T-Box and enters into a dormant state; the Internet-of-vehicles service platform starts background timing, and the T-Box is woken and a start charging request is sent to the T-Box when the charging reservation time is reached; and after receiving the start charging request, the T-Box wakes up a vehicle controller and a power battery management system through a CAN network to enter into an alternating current charging process. The electric vehicle reservation charging control method and system can avoid the charging peak period and rationally utilize power grid resources.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for controlling reserved charging of electric vehicles. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of people's living conditions, automobiles have become one of the indispensable means of transportation for people to travel. Car ownership is increasing year by year, and more and more people own private cars. At present, with the continuous improvement of people's awareness of environmental protection, new energy vehicles, especially electric vehicles, have developed rapidly. [0003] At present, the charging method of electric vehicles is that when the user needs to charge, the electric vehicle is parked at the charging pile and charged immediately. With the increasing number of electric vehicles, the power supply pressure on the power grid is increasing. At present, this charging met...

Problems solved by technology

[0003] At present, the charging method of electric vehicles is that when the user needs to charge, the electric vehicle is parked at the charging pile and charged immediately. With the increasing number of electric vehicles, the power supply pressure on the power grid is increasing. At present, this charging method is easy The emergence of charging peak hours, resulting in unreasonable use of grid resources, in the long run, increases the charging cost of electric vehicles
