The position that signal calculates the charging pile 100 is broadcast, when the charging pile position is in the chargeable range of vehicle, described in control
Vehicle end directional aerial 401 sends request signal.When vehicle end processor 403 can be according to the arrival of the broadcast singal received
Between, the location algorithm combination day of one or more of reaching time-difference, angle of arrival and the signal strength that receives parameter
One or more information such as beta radiation directional diagram, height of car calculate the position of charging pile.The request signal can include vehicle
Identity information, be authenticated matching between vehicle and charging pile so as to the stake end processor 202 of charging pile.
In vehicle end, it is only necessary to which on the driver control area such as console of vehicle, one button of installation is as vehicle
The starting switch of control device is held, vehicle can be communicated and be matched with charging pile automatically, realize automatic charging.Thus
It saves and area is controlled in vehicle, reduce the repacking cost to vehicle, missed without overstaffed intervention so as to prevent driver
The possibility of operation.Between each vehicle and charging pile without networking, without the charging pile that prestores map and location information or
Accurate positionin that just can be between real charging pile and vehicle by other reference marks.
Charge control system provided by the invention, including the stake end control device with end directional aerial and with vehicle
The vehicle end control device of directional aerial is held, the reception of stake end directional aerial and the main lobe direction of radiation beam are located at charging pile
Chargeable range in, and the reception of vehicle end directional aerial and the main lobe direction of radiation beam are located at right over roof；Therefore, only
Have when in chargeable range of the vehicle to be charged near or at the charging pile, vehicle can just receive charging pile and send out
Broadcast singal and charging pile can just receive the request signal of vehicle transmission, adjacent charging pile will not be received so as to vehicle
Broadcast singal interference and charging pile will not further be counted by the signal interference of the vehicle at other positions by position
It calculates, it is possible to avoid generating to miss between adjacent charging pile and vehicle to be charged communicating.In the environment of multiple charging piles, respectively
Can be mutual indepedent between a charging pile, the essence between charging pile and vehicle to be charged just can be accurately realized without positioning via network
Accurate one-to-one matching, the matching and certification between arbitrary vehicle and charging pile can be realized by reliable wireless communication link,
It can realize automatic charging of the charging pile to vehicle.
The specific embodiment of the present invention also provides a kind of electric vehicle charge control method.
Fig. 6 is please referred to, is the flow chart of the Vehicular charging control method, with reference to Fig. 7 and Fig. 8, Fig. 7 is charging pile
