Abstract

The invention relates to a charging method and system for an electric automobile. The charging method for the electric automobile includes the following steps that charging demand information of the electric automobile connected with a charging pile is read, and multiple charging schemes of various time-priced value combinations corresponding to the electric automobile are calculated according to the charging demand information and a preset pricing function model, wherein the time-priced value combinations refer to charging time periods for charging the electric automobile by the charging pile and priced values corresponding to the charging time periods; the charging schemes are sent to user terminal equipment to be displayed, and a selected scheme selected by a user in the charging schemes is read; output parameters of the charging pile are set according to the selected scheme, and the charging pile is controlled to charge the electric automobile according to the output parameters; the electric automobile can be charged in order, load distribution of a corresponding automobile charging system is balanced, and the charging effect of the electric automobile is improved.

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...
