In electric automobile 2 driving process, the capacity of on-vehicle battery is monitored by on-vehicle battery detection unit 24, the on-vehicle battery residual capacity information of monitoring is transferred to cloud processing module 1 by vehicle-carrying communication unit 22 by vehicle-mounted central processing unit 25, real-time road acquiring unit 14 obtains real-time road, and cloud processing unit 12 calculates destination's course continuation mileage of electric automobile 2 according to the real-time road of on-vehicle battery residual capacity information and acquisition.The method calculating destination's course continuation mileage is as follows: according to real-time road, with reference to predetermined real-time vehicle speed intervals, programme path is divided into multiple route segments, and wherein the average speed in real time in each route segments belongs to same real-time vehicle speed intervals；Such as, can be 0-20 kilometer/hour, speed per hour 20-40 kilometer/hour, speed per hour 40-60 kilometer/hour, speed per hour 60-80 kilometer/hour, above totally 5 the real-time vehicle speed intervals (according to the speed per hour spacing of every 10 kilometers or 5 kilometers, real-time vehicle speed intervals can also be divided) of speed per hour 80 kilometers/hour division according to speed per hour；Real-time road acquiring unit 14 obtains the average speed in real time of this monitoring point (such as from each real-time vehicle-speed monitoring point that programme path is set up along the line, monitoring point utilizes test the speed shooting or the velocity coils acquisition real-time speed by each car of this monitoring point, and in timing statistics section, such as every 3 minutes is a timing statistics section, add up this time period average speed in real time through the rolling stock of this point), further according to the real-time vehicle speed intervals belonging to the average speed in real time of monitoring point, corresponding route segments is included in section corresponding for this monitoring point；Finally, add up the total length of route segments corresponding to each real-time vehicle speed intervals, as, on programme path, speed per hour is the route segments total length 5 kilometers of 0-20 kilometer/hour, the route segments total length of speed per hour 40-60 kilometer/hour 7 kilometers, the route segments total length of speed per hour 60-80 kilometer/hour 15 kilometers；Every kilometer of capacity consumption value under built-in different speed per hours is uploaded to cloud processing module 1 by on-vehicle battery detection unit 24, cloud processing module 1, according to each route segments total length and the battery remaining power corresponding with vehicle speed intervals in real time of every kilometer of capacity consumption value under different speed per hours, calculates destination's course continuation mileage of electric automobile 2.In order to adapt to the change of road conditions, namely cloud processing module 1 recalculates and updates destination's course continuation mileage of electric automobile 2 every a predetermined time period (such as 5 minutes, 10 minutes).
When cloud processing unit 12 judges that destination's course continuation mileage is not enough to arrive at the destination, cloud processing unit 12 will provide the emergency power supply 3 that can be used for charging for electric automobile 2.And in prior art, can according to travel route along the line on each emergency power supply, cook up the electric automobile current location travel route to each emergency power supply, judge further according to the real-time road on travel route and on-vehicle battery residual capacity whether the course continuation mileage of electric automobile can arrive emergency power supply, thus picking out the accessibility emergency power supply of electric automobile, the computational methods of this course continuation mileage are identical with destination described above course continuation mileage.
" travel route is along the line " as herein described refers to that the emergency power supply most short lines distance to travel route is less than 3 kilometers.
But the present invention's it was discovered by researchers that owing to peak jam situation on and off duty often changes, for instance the factors such as aggravation of blocking up, cause that the course continuation mileage of arrived in the emergency power supply 3 that cloud processing unit 12 calculated at that time is not enough to the emergency power supply travelled to remotely.Therefore, destination's course continuation mileage is multiplied by factor of safety by research worker of the present invention, thus obtaining safe mileage, this safe mileage is that electric automobile 2 can not be affected by jam situation change, and ensure that electric automobile uses the mileage that battery dump energy travels.Cloud processing unit 12 calculates the distance of travel route emergency power supply along the line 3, thus judging that travel route which emergency power supply along the line can carry out the emergency power supply of emergent charging as user.Obviously, time safe mileage is bigger, available emergency power supply is also just more；Time safe mileage is less, available emergency power supply is also just less.
The computational methods of safe mileage are, destination's course continuation mileage * factor of safety=safe mileage.Factor of safety is the empirical value that research worker of the present invention obtains according to big data analysis, and its value is as follows: when the time calculating safe fare register is 7:00-10:00 and 17:00-20:00, factor of safety value 0.6；When the time calculating safe fare register is 10:00-11:00 and 16:00-17:00, factor of safety value 0.7；When the time calculating safe fare register is 11:00-16:00,21:00-24:00 and 0:00-6:00, factor of safety value 0.8.It is exemplified below: it is 30 kilometers that cloud processing unit 12 calculates destination's course continuation mileage that electric automobile 2 arrives at, and the time now calculating safe fare register is 7:30, then now factor of safety value is 0.6, then the safe mileage of this electric automobile 2 18 kilometers.If it is 20 kilometers that this electric automobile 2 arrives the traveling distance of certain emergency power supply, then cloud processing unit 12 will not select this emergency power supply to be charging electric vehicle；If it is 15 kilometers that this electric automobile 2 arrives the traveling distance of this emergency power supply, then cloud processing unit 12 by select this emergency power supply be user charge one of alternative.
For the electric automobile 2 that safe mileage is little, available emergency power supply is also just less, therefore should preferentially use emergency power supply 3 nearby.Therefore, when the safe mileage of electric automobile 2 is not more than 5 kilometers, cloud processing unit 12 distributes manual mode for electric automobile 2, is pushed on the touch display screen 23 of this electric automobile 2 by all emergency power supplies in this safe mileage of electric automobile 2；When the safe mileage of electric automobile 2 is more than 5 kilometers, cloud processing unit 12 distributes automatic mode for electric automobile 2, travels outside distance 5 kilometers for the distribution of this electric automobile 2 but a certain emergency power supply in all available emergency power supply within safe mileage.
Manual mode is further illustrated referring to Fig. 3, in a manual mode, the reservation charging interval of each available emergency power supply divides hours section according to each hour between each integral point, each hours section is divided into again 6 minutes sections, and the duration of each minutes section is 10 minutes.Cloud processing unit 12 sends the emergency power supply after all selecting to electric automobile 2 by cloud communication unit 13, simultaneously, cloud processing unit 12 calculates electric automobile 2 and arrives the time of corresponding emergency power supply 3, and touches, at electric automobile, the minutes section demonstrated on display screen 23 after the minutes section and this minutes section that this electric automobile arrives.Being divided into two parts after the time that user is arrived emergency power supply 3 by cloud processing unit 12, a part is the subscription time section that other users have preengage, and another part is free time section.The time period of the two part can be discontinuous, but its time span is all 10 minutes, and overlaps with minutes section.Owing to the output electric current of emergency power supply is 4C, so the capacity that charging can make on-vehicle battery for 10 minutes supplements more than 50%, general enough electric automobile during travelings are to destination.Such as, the time of cloud processing unit 12 anticipating user arrival A emergency power supply is 11:54, then the emergency power supply initial time on touch display screen 23 is 11:50,12:00-12:10 is free time section after this, 12:10-12:40 is other user's subscription time sections, 12:40-13:30 is again free time section, and 13:30-13:50 is also other user's subscription time sections, is all free time section after 13:50.Cloud processing unit 12 is by above-mentioned information pushing to electric automobile 2, and the vehicle-mounted central processing unit 25 of electric automobile 2 is shown on touch display screen 23.The corresponding time period of single emergency power supply 3 shows in the way of a trunnion axis, and this trunnion axis marks, with two kinds of colors, time period and the free time section that other users have preengage respectively.At this moment touch on display screen 23 and show a plurality of time shaft, to represent the time period of multiple emergency power supply 3, select for user.User only needs to click the emergency power supply 3 wanted, and clicks the corresponding time period, and this emergency power supply 3 can be gone to be charged.But road conditions can be continually changing in the process of moving, it is possible to cause that user cannot arrive this emergency power supply in subscription time section.If cloud processing unit calculates electric automobile for first 10 minutes cannot arrive emergency power supply in selected free time section selected free time section on time, the free time section then selected is cancelled and is distributed to other electric automobiles arriving emergency power supply by cloud processing unit, and cloud processing unit selects time upper nearest free time section for late electric automobile automatically.If this user is late again, then by that analogy.Such as, user clicks and have selected 12:40-12:50 and be charged, and yet with blocking up, cloud processing unit calculates electric automobile for first 10 minutes cannot arrive emergency power supply in selected free time section on time the free time section selected by this electric automobile.Now, the time period that this electric automobile is taken by cloud processing unit 12 is cancelled, and distributes to other electric automobiles arriving emergency power supply, if other electric automobiles not having arrived at, then the free time section of this cancellation is once again shown as free time section；Simultaneously because 12:50-13:10 is holding time section, 13:10-14:00 is free time section, then 13:10-13:20 is distributed to this electric automobile that cannot on time arrive by cloud processing unit 12.
In automatic mode, the reservation charging interval of each available emergency power supply divides hours section according to each hour between each integral point, only allows 6 electric automobiles to be charged in each hours section.Cloud processing unit 12 calculates electric automobile and arrives the time of each emergency power supply, thus judging that this electric automobile will be charged in certain hours section of this emergency power supply, and the reservation accounting of each hours section according to each emergency power supply, automatically distributes, for electric automobile, the emergency power supply that in the hours section that this electric automobile arrives, reservation accounting is minimum and is charged.If reservation accounting is identical, then it is automatically assigned to and reaches the emergency power supply that required time is minimum.Reservation accounting herein refers in certain hours section, and the electric automobile number having distributed reservation charging accounts for the ratio of this time period maximum allowable electric automobile number.Such as, the time of electric automobile arrival emergency power supply A is 12:20, and the hours section of emergency power supply A is 12:00-13:00, and this hours section has been subscribed to 3 electric automobiles, and its reservation accounting is 3/6；The time of electric automobile arrival emergency power supply B is 11:50, and the hours section of emergency power supply B is 11:00-12:00, and this hours section has been subscribed to 5 electric automobiles, and its reservation accounting is 5/6；.The time of electric automobile arrival emergency power supply C is 12:50, and the hours section of emergency power supply A is 12:00-13:00, and this hours section has been subscribed to 3 electric automobiles, and its reservation accounting is 3/6.Therefore, cloud processing unit 12 finally distributes emergency power supply A automatically for electric automobile.And all electric automobiles for having preengage in the hours section in emergency power supply, then it is charged according to arriving first the principle first filled.
