Control method and system for electric vehicle remote charging

Abstract

The invention provides a control method and system for electric vehicle remote charging. The control method comprises the steps that a charging request sent by a vehicle-mounted terminal is received,and the charging request comprises multiple charging modes of a to-be-charged vehicle; according to the remaining power of a charging station, optional charging modes are determined from the multiplecharging modes of the to-be-charged vehicle, and the remaining power is a difference value between a rated output power and an actual output power of the charging station; a charging instruction is sent to the vehicle-mounted terminal to make the to-be-charged vehicle select one charging mode for charging from the optional charging modes, and the charging instruction comprises the optional charging modes among the multiple charging modes. According to the control method and system for electric vehicle remote charging, the charging modes of the to-be-charged vehicle are controlled to realize the control of the actual output power of the charging station, thereby solving the problem that the charging station is overloaded for a long time, improving the reliability and utilization of the charging station, and reducing the failure rate of the charging station.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control method and system for remote charging of electric vehicles. Background technique [0002] Automobile is an important means of transportation in modern society, and it is also an important pillar industry of the national economy. Although traditional fuel vehicles have brought many conveniences to people's lives, they have been highly valued as major polluters. Therefore, the new energy vehicle industry has developed rapidly, especially pure electric vehicles with their pollution-free, low noise, and stable operation. and other advantages have been vigorously promoted. [0003] Existing pure electric vehicles need a charging station to charge them. When more than a certain number of vehicles are charging at the charging station, the output power of the charging station will easily exceed the rated output power, and it is impossible to remotely manage the outpu...

AI Technical Summary

Problems solved by technology

[0003] Existing pure electric vehicles need a charging station to charge them. When more than a certain number of vehicles are charging at the charging station, the output power of the charging station will easily exceed the rated output power, and it is impossible to remotely manage the output power of the charging station and control the charging of the vehicle. The charging station is overloaded for a long time, which reduces the reliability of the charging station, increases the failure rate of the charging station, and increases the cost of equipment maintenance.
