Abstract

A method for controlling the charging of segments for an online electric vehicle is described. In some situations, the method comprises: (a) receiving, from segments, information on the speed and position of the vehicle entering the range of the power-supplying device; and (b) controlling the charging/discharging timing of the current segment from which the vehicle is leaving and the next segment into the range of which the vehicle is to enter, in accordance with the information on the speed and position of the vehicle. The charging/discharging response delay characteristics of the segments may be considered.

Claims

1. A method for controlling the charging of segments for an online electric vehicle, comprising:

(a) receiving information, from segments, regarding the speed and position of an entering vehicle; and

,

(b) controlling the charging/discharging timing of the current segment from which the vehicle is leaving and the next segment into the range of which the vehicle is to enter, in accordance with the information on the speed and position of the vehicle.

2. The method according to claim 1, wherein step (b) comprises:

(b1) discharging one segment before the vehicle has completely advanced, in accordance with the segment discharging response time; and

(b2) charging the next segment into the range which the vehicle is to enter, in accordance with the segment charging response time.

3. A method for controlling the charging of segments for a number of online electric vehicles comprising:

(a) charging the nth segment, where n is an integer, greater than one, in accordance with the entering of the lead vehicle, in the case where there are a number of vehicles;

(b) receiving information from the n−

1th segment, regarding the speed and position of following vehicles;

(c) receiving discharging requests from the nth segment in accordance with the entering of the lead vehicle; and

,

(d) approving or rejecting the discharging of the nth segment in accordance with the information on the speed and position of the lead and following vehicle.

4. The method of claim 3, wherein, preceding step (a), the method for controlling the charging of segments for an electric vehicle includes:

receiving information from the n+1^th segment on the speed and position of the lead vehicle; and

, charging the n^th segment in accordance with the information on such speed and position.

5. The method of claim 3 wherein step (d) comprises:

(d1) if it is determined that the following vehicle will enter before the discharging of the Nth segment is complete, the charging state of the Nth segment is maintained; and

/or,

(d2) wherein if it is determined that the following vehicle will enter after the discharging of the Nth segment is complete, the Nth segment will be discharged.

6. The method of claim 5, wherein subsequent to step (d2) the method comprises charging the segment into range of which the following vehicle will enter is charged, in accordance with the N^th segment charging response time.

7. A method for controlling the charging of segments for an online electric vehicle, comprising:

(a) designating a lead vehicle as the header vehicle, among a group of vehicles;

(b) charging an Nth, where n is an integer greater than one, segment in accordance with the advancement of the header vehicle;

(c) receiving information from the N−

1th segment regarding the speed and position of the vehicle following the header vehicle;

(d) receiving a discharging request from the Nth segment, in accordance with the advancement of the header vehicle; and

(e) approving or rejecting the discharging request in accordance with the information on the speed and position of the header vehicle and following vehicle.

8. The method of claim 7, wherein a group of vehicles is determined to exist in accordance with the information of the recorded gap between each vehicle, vehicle ID and/or the movement speed of each vehicle.

9. The method of claim 7, wherein prior to step (a) the method comprises receiving information from the N+1th segment, regarding the speed and position of the header vehicle, and charging the nth segment in accordance with information regarding such speed and position.

10. The method of claim 8, wherein step (e) comprises:

(e1) if it is determined that the following vehicle will enter before the discharging of the Nth segment is complete, maintain the charging state of the Nth segment; and

/or,

(e2) if it is determined that the following vehicle will enter after the discharging of the Nth segment is complete, discharging the Nth segment.

11. The method of claim 10, wherein subsequent to step (e2) the method comprises charging of the segment which the following vehicle will enter, before it enters, in accordance with the charging response time of the nth segment.
