Abstract

The embodiment of the invention provides a charging method, device and system for an electric automobile. The charging method comprises the following steps that after a plug of a charging pile is inserted in a socket of the electric automobile, the charging manner is detected by the electric automobile; when a situation that a high level is generated on an A+ line is detected, the electric automobile determines to adopt a direct-current charging manner, and the electric automobile is charged by the charging pile through the A+ line; or when a situation that the high level is generated on a CP line is detected, the electric automobile determines to adopt an alternating-current charging manner, and the electric automobile is charged by the charging pile through the CP line. When the electric automobile needs urgent charging, the charging pile can adopt the direct-current charging manner to charge the electric automobile; when the electric automobile does not need urgent charging, the charging pile can adopt the alternating-current charging manner to charge the electric automobile. According to the charging method disclosed by the invention, two charging manners can be provided, the required charging manner is selected according to actual needs; the charging manner is flexible; and the requirement of temporarily and urgently charging the electric automobile can be met.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method, device and system for charging an electric vehicle. Background technique [0002] An electric vehicle (Blade electric vehicle, BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, uses a motor to drive the wheels, and meets the requirements of road traffic regulations and safety regulations. Electric vehicles use on-board power supply as the power source to reduce the consumption of non-renewable resources—petroleum, zero emissions and pollution-free, and become one of the hot spots in the automotive industry today. [0003] For existing electric vehicles, when charging, the staff selects the charging method to be adopted, and inserts the charging plug on the charging pile into the charging socket of the electric vehicle. During the charging process, only the staff can know the charging method used. Electric vehicles and charging piles...
