Embodiment Construction

[0013] A charging method for an electric vehicle charging pile, comprising the following steps:

[0014] S1: The user inserts the plug of the battery of the electric vehicle into the charging socket of the charging pile;

[0015] S2: Insert the charging card into the charging pile, the charging plug reads the user information in the charging card, and checks the corresponding validity of the charging card, the battery pack, and the electric vehicle.

[0016] S3: The charging main control unit sends a power-on command to the AC contactor to start charging; at the same time, the metering unit connected in series on the line between the power grid and the charging socket starts to measure the power, and transmits the metering information to the charging main control unit;

[0017] S4: In the case of continuing charging, the main control unit collects and detects the unbalance degree between the battery packs and the single cells. If it exceeds the preset value, an alarm display i...

Abstract

The invention relates to a charging method for an electric vehicle charging pile. The charging method comprises the following steps of: (1) plugging a plug of a battery of an electric vehicle into a charging socket of the charging pile by a user; (2) inserting a charging card into the charging pile, reading user information in the charging card by a charging bolt, detecting corresponding validity among the charging card, a battery pack and the electric vehicle, if yes, continuously charging, if not, reminding of pulling the card out; (3) starting to meter electric quantity by a metering unit at the beginning of charging, and transmitting metering information to a charging main control unit; (4) acquiring unbalance degree between the battery pack and a single battery by the main control unit on the condition of continuously charging; and (5) displaying balance in the charging card by a display unit after finish, and judging balance between the battery pack and the single battery. By the charging method, overhigh or over-low charging voltage can be effectively avoided, battery performance cannot be damaged, the service life of the battery is prolonged, and the safety of the electric vehicle during charging process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a charging method for electric vehicle charging piles. Background technique [0002] With the increasingly intensified contradictions between economic development, energy supply, and environmental pollution, energy conservation and consumption reduction and reduction of dependence on fossil fuels have become urgent problems to be solved for the sustainable economic development of countries all over the world. Electric vehicles have the advantages of fuel saving, environmental protection, and high efficiency. The supporting charging network is an indispensable support system, which is a prerequisite for the promotion of electric vehicles, similar to gas stations for traditional fuel vehicles. [0003] The charging of electric vehicles is mainly provided by charging plugs, but the known charging piles are often only a kind of equipment that provides electric energy supplemen...
