Description

technical field

[0001] The invention relates to the field of electric power technology, in particular to a charging method and system for an electric vehicle. Background technique

[0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. With the increasingly serious environmental and energy problems, electric vehicles have received widespread attention due to their advantages in energy saving, environmental protection, and cleanliness.

[0003] During the use of electric vehicles, they need to be charged by the vehicle charging system connected to the grid to ensure the sufficiency of energy during their operation. At present, the charging scheme of electric vehicles is to charge the electric vehicles that need to be charged immediately, which leads to a large number of electric vehicles randomly connected to the vehicle chargin...
