The specific embodiment

Describe with regard to structure and action according to Fig. 1, Fig. 2.

Fig. 1 is that an elec. vehicle is near station, an other approximate vertical view that leaves the state at station, 1a, 1b are one or two supply line, the 2nd, trolley pole or collector bow, the 3rd, driver train, the 4th, consumer unit and sign, the 5th, CD-ROM drive motor, the 6th, power storage body (electric storage means or storage battery).Fig. 2 is the summary elevation view of seeing from the rear.

Utilize Fig. 1 just to move and describe, vehicle 7 simultaneously slows down one side near the station with the state that is folding trolley pole 2.After stopping AT STATION, driver train 3 moves trolley pole 2, and as shown in Figure 2, contacts with supply line 1a with intrinsic contact pressure, and described supply line 1a opens and is located on the stringing bar that stands in footway and moving traffic lane intersection.Like this, after other approach of consumer unit 4 usefulness are distinguished the power supply permission, carry charging power to power storage body 6 via supply line 1a, trolley pole 2.Afterwards, parking period finishes to begin to quicken, and also carries charging power in this programme in acceleration, and further acceleration itself also transmits electric power with motor 5 to wheel drive through supply line 1b.

As mentioned above, this programme is except charging in parking, by supply line 1b in acceleration, also charge and (or) obtain quickening electric power, and supply line 1 is arranged on the intersection sky rather than the moving traffic lane sky of footway and moving traffic lane, suitably control from the contact of the trolley pole 2 of vehicle by driver train 3 and press.(vehicle 8 one side on Fig. 1 right side is quickened one side and is left stringing, therefore contacts drops) and, in order not hinder moving traffic lane, supply line 1 is arranged on footway and moving traffic lane intersection, but also can be arranged on the moving traffic lane.And, the trolley pole 2 that driver train 3 can utilize spring etc. to open with the tension force adjustment of electric wire etc.

(the acceleration area distance is about 20～30m) end about 10 seconds is carried out in above-mentioned acceleration approximately, and supply line 1 also interrupts.Afterwards, vehicle enters the interval of travelling, and vehicle 8 uses the electric power that is loaded in the power storage body 6 in the car to travel.In the example of Fig. 2, represented two supply line, but also can resemble the electric car, also above-mentioned supply line 1 can be arranged on higher position with a formation, make trolley pole 2 towards oblique upper, utilize.

Fig. 3 represents the car inner structure of elec. vehicle 7,8.9, the 10, the 11st, electric switch, the 12, the 13rd, current control loop.Utilize this figure that action is described, at first at vehicle when the station, only open switch 11, so-called regeneration electricity passes through current control loop 12 and carries out additional charge to power storage body 6.Only open switch 9 at parking period then, carry out additional charge by supply line 1.After the pick-up time band, only open switch 9 and (or) switch 10, to wheel drive with motor 5 and (or) power storage body 6 transmits electric power.

The state that the energy of the expression of 14 among Fig. 4 power storage body 6 changes according to above-mentioned action.The longitudinal axis of this figure represents that with the station Energy Unit (EU) of travelling transverse axis is the time.The concrete meaning of the power storage body 16 of example is that the energy that four parts of stations travelled in the garage sets out after power storage body 6 electric power storages, and charge capacity 16 reduces along with travelling.By near the 1. time regeneration electricity that slows down and produces of the 1-at first station, charge capacity 16 increases, 2. charge capacity 16 further increases at 1-3. during the parking of time the time from 1-.

And, from 1-3. to 1-pick-up time 4., be that charge capacity 16 transfers minimizing at present, but in native system, the energy that makes vehicle quicken not only not use power storage body 6, and to power storage body 6 chargings, therefore, charge capacity 16 constantly increases.From 1-4. enter the interval of travelling, charge capacity 16 transfers minimizing to, lasts till second station fwd deceleration point 2-1., repeats foregoing after 1. 2-puts.

Suppose that concrete numerical value verifies.If service voltage=800V, the electric current=100A during vehicle ', the electric current=200A when vehicle quickens is to the electrically-charged maximum current=100A of power storage body.During deceleration with 800V * 100A * 10 second, during parking with 800V * 100A * 20 second, during acceleration with the energy of 800V * 100A * 10 second to power storage body 6 chargings.And the car speed of supposition after quickening be 50Km/ hour, then be 50Km/3600 * 40 second=550m, slows down and the zone distance of acceleration then be about 600m if add.If the mean distance conversely speaking, between the station is 600m or below the 600m, then shown in the charge capacity 16 of Fig. 4, no matter can travel in what stations always.
