Along with the progress of new energy technology, the technology relevant with electric motor car is continually developed.Charging problems are electricity
One key problem of motor-car.Prior art common practice is：Remind user to charge when the battery electric quantity of electric motor car is not enough,
And help user to search neighbouring charging station；Or whether calculate electricity before travel in user sufficient, fill if necessary in way
Electricity, then the charging route calculating some optimizations (is for example told in user's trip way relatively save time to which charging station charge ratio, is arrived
Which charging station is fewer around row distance, etc.).However, these prior arts are all only to consider the current information gone on a journey to determine
Determine how to charge, and be all to charge in trip way, the time of staying not making full use of vehicle in destination is charged.
In addition, some existing charging techniques need to know the detailed plan of travel of user, including the starting point of each trip,
Terminal and corresponding time.Then, charging scheme is obtained based on this plan of travel.During user's trip, need reality
When monitoring user actual trip whether consistent with initial plan.If it find that the actual trip of user changes and (for example rises
Point, terminal or time etc. are not inconsistent with original plan), then need to update plan of travel and charging scheme.

Continually to interact with user to determine related data.Further, since formulating plan of travel to need accurate beginning and end, but
(such as user After Hours can first go to restaurant to have a meal daily, but meal to be sometimes difficult to provide in advance specific place for a user
The place in shop is not fixed while and often just determines gone to which restaurant before setting out).In addition, the prison in existing charging technique
During control, as long as the plan of travel of discovery user and original plan are not inconsistent being necessary for updating charging scheme, this leads to the frequency of data
Numerous renewal.However, in practice, the change of some behaviors can't affect charging scheme, so charging side in fact need not be updated
Case.
Additionally, the whole process that charging room topic can use with electric motor car.If it is following long-term to consider user
Travel behaviour, thus determine each charging interval, charging modes etc., it will bring the income of global optimum to user.For example,
In the face of time-of-use tariffs policy, consider the trip of following a period of time, then can be arranged in trough-electricity the charging interval as far as possible
During valency.And it may be considered that only filling part electricity in peak electricity tariff and when must charge, the charging of user so will be substantially reduced

Specific embodiment
Below, by combining the description of the specific embodiment to the present invention for the accompanying drawing, the principle of the present invention and realization will become
Obtain substantially.It should be noted that the present invention should not be limited to specific embodiments described below.In addition, for simplicity province
Omit the detailed description of known technology unrelated to the invention.
First embodiment
Fig. 1 shows the block diagram of charging system according to an embodiment of the invention.As shown in figure 1, in the present embodiment
Charging system 10 to include plan of travel creating unit 110, charging scheme computing unit 120, monitoring unit 130 and analysis single
Unit 140.
Plan of travel creating unit 110 is based on travel time and distance and creates plan of travel.Plan of travel can be used
In following one day or the even more plan of travel for a long time of some skies, it can comprise the time of following each trip of user at family
And distance.
Table 1 below gives an example of the plan of travel being created by plan of travel creating unit 110：
Table 1
Table 1 is made up of a series of row, each row include departure time and this trip once gone on a journey starting point it
Between trip distance.Additionally, each row also include the time of advent and the time of staying, the wherein time of advent and the time of staying can be with base
Pass through to be calculated in departure time and trip distance.For example, the time of staying can calculate according to the example below method：
Assume the time of staying of the destination that Stop_Time (n) represents that user goes on a journey in n-th：
Stop_Time (n)=TimDiff (End_Time (n), Start_Time (n+1))
Wherein, TimeDiff (T, T ') represented from time T to T ' time difference, the End_Time time of advent (n) is to be based on
Departure time Start_Time (n) estimation obtains, and n+1 represents the trip next time of n-th trip.
Plan of travel creating unit 110 can history trip data based on user, to be created that by way of prediction
Row plan.For example, within a period of time in past, user morning 7 on every Mondays are found:00 about will drive from the home to company, away from
From for 15km.Then dock to afternoon 6 near Che company:00 drives body-building shop again, etc..So according to this history number
According to can predict that the trip of next Monday user is likely to is also so, i.e. morning 7:00 about will drive from the home to company, distance
For 15km....
In addition, plan of travel creating unit 110 can also create plan of travel based on manually entering of user.Alternatively
Ground, plan of travel creating unit 110 may also provide the plan of travel predicted, is then confirmed by user and changes partial content.
For example, when user knows starting point title but do not know track pitch from when, specific starting point can be inputted, created by plan of travel single
First 110 automatic calculating trip distances.In addition, when user only knows trip distance, but when also not knowing specific starting point, also may be used
To directly input trip distance.
Charging scheme computing unit 120 calculates charging based on the plan of travel that plan of travel creating unit 110 is created
Scheme.Specifically, charging scheme computing unit 120 can look to the future trip distance, each destination the time of staying
And the factor such as electricity price, in conjunction with the demand to charging cost for the user, from overall situation consideration be given optimal charge point, charge hundred
The time divided than and spent and price etc., thus calculate the optimum charging scheme (optimum charging scheme) of charging cost.
For example, this optimum charging scheme meet following at least one：In way, the charging interval is the shortest, charging quality preferably and charging price
Minimum.In this application, charging quality is best is meant that most beneficial for the service life extending battery.For example, once by electricity
Pond is full of and be continually that battery charges but is more beneficial for life-span of prolongation battery compared with not all being full of.Additionally, charging modes
Including filling soon and trickle charge：Generally, trickle charge will about 8 hours can be fully charged, and fill half an hour soon and can be charged to battery electric quantity
80%.It will be understood to those skilled in the art that ratio is more beneficial for extending battery by the way of filling soon by the way of trickle charge
Life-span.
Different charging schemes can be obtained according to different optimisation strategy.According to an embodiment it is desirable to as far as possible
By the use of vehicle in the time of staying as the charging interval of destination, thus reducing the time spending because of charging.When vehicle is at certain
When the time of staying of individual destination is more than the required minimum charging interval, it is possible to use charge in the time of staying of destination
(that is, charge point is in the destination of trip).When the distance that certain is gone on a journey is more than fully charged course continuation mileage, then need in trip
Charge in way (that is, charge point is not in the destination of trip).
Table 2 below gives by an example of the calculated charging scheme of charging scheme computing unit 120：
Table 2
Monitoring unit 130 monitors whether actual trip occurs deviation with plan of travel.For example, monitoring unit 130 can be real
When ground obtain travel time of actual trip of user's vehicle and position, compare the actual trip of user in real time whether and trip
Plan is consistent.If consistent, monitoring unit 130 continues monitoring；If it is inconsistent, the actual trip of explanation user and trip
Plan has deviation.
If there is deviation, then analytic unit 140 analyzes whether this deviation affects nearest charge point in charging scheme.As
Fruit does not affect this charge point, then monitoring unit 130 continues the trip of monitoring user.Otherwise, if having influence on this charge point, divide
Analysis unit 140 makes plan of travel creating unit 110 re-create plan of travel, and makes charging scheme computing unit 120 be based on weight
Charging scheme is recalculated in the new plan of travel creating.
According to an embodiment, analytic unit 140 to analyze whether this deviation affects in charging scheme the most as follows
Near charge point：
(1) when the actual trip distance of user has deviation with plan of travel
If the deviation of the predetermined trip distance in actual trip distance and plan of travel is more than threshold value (Thd), then will
Nearest charge point can be affected.Otherwise although trip distance is varied from, but as long as the stop of the destination at this charge point place
Time is unaffected then it is assumed that this deviation does not affect nearest charge point.
According to an example it is assumed that CurDrealRepresent current actual trip distance of going on a journey, CurDplanRepresent plan of travel
In this trip predetermined trip distance.If CurDreal=CurDplan, illustrate predetermined in actual trip distance and plan of travel
Trip distance zero deflection.Otherwise, illustrate that actual trip distance has deviation with the predetermined trip distance in plan of travel.If this is inclined
The absolute value of difference | CurDreal-CurDplan| more than threshold value Thd, illustrate that this deviation will affect nearest charge point.Wherein, threshold
The value of value Thd can be：
(1) work as CurDreal＞ CurDplanWhen, Thd=RemDplan.Wherein, RemDplanRepresent and travel in plan of travel
To remaining travel distance during nearest charge point.This condition represents that actual trip distance is more than predetermined trip distance, and this difference
The remaining travel distance making vehicle is not enough to reach nearest charge point.
(2) work as CurDreal＜ CurDplanWhen, Thd=(RemDplan+NextDplan).Wherein, NextDplanRepresent and fill recently
The plan trip distance of the first time trip after electricity point.This condition represents that actual trip distance is less than predetermined trip distance, and should
Difference enable to nearest charge point move backward to next time trip after.
For example, it is assumed that the beginning and end of certain trip travel 1 is L1 and L2 respectively, nearest charge point A is another
The once terminal of trip travel 2.It is further assumed that the actual range of travel1 is 30km, and in plan of travel from L1 to L2
Trip distance be 20km and the trip distance from L2 to L3 be 18km, the remaining travel distance to nearest charge point A is 5km.
Because the actual trip distance of travel1 is more than plan trip distance, and deviation is 30-20=10km, and this deviates more than threshold value
5km.Therefore analytic unit 140 judges that the change of this travel behaviour is bound to affect nearest charge point A.
(2) when the actual travel time of user having deviation with plan of travel
If the deviation of the predetermined travel time in actual travel time and plan of travel is more than threshold value (Thd), then will
Nearest charge point can be affected.Otherwise, although going out on the premise of the actual trip distance of user is without departing from maximum course continuation mileage
The row time is varied from, but thinks that this deviation does not affect nearest charge point.
According to an example it is assumed that CurTrealRepresent the actual time that this trip arrives at, CurTplanRepresent
The row predetermined travel time that this trip arrives in the works.If CurTreal=CurTplan, the actual travel time is described
With the predetermined travel time zero deflection in plan of travel.Otherwise, the predetermined trip in actual travel time and plan of travel is described
There is deviation time.Based on CurTrealPrediction user reaches time (the i.e. NCPT of nearest charge pointreal).NCPTplanRepresent
The time of nearest charge point is reached in plan of travel.Work as NCPTrealEarly than NCPTplanWhen, stopping in this charge point will not be caused
The time is stayed to reduce, so not affecting this charge point.Work as NCPTrealIt is later than NCPTplanWhen, can cause in the stop of this charge point
Between reduce, then judge this deviation (NCPTreal-NCPTplan) whether it is more than threshold value (Thd), wherein Thd=NCPSTime-
NCPChTime, NCPSTime represent the plan time of staying in nearest charge point, and NCPChTime represents in nearest charging
Point charges the required time.If (NCPTreal-NCPTplan) ＞ Thd, illustrate that the charging interval in nearest charge point will not
Foot, so this deviation can affect nearest charge point.Otherwise although can reduce in the time of staying of charge point, but do not affect to fill
Electricity, i.e. this deviation does not affect nearest charge point.
For example, it is assumed that the beginning and end of certain trip is L4, L5 respectively, nearest charge point B is located at this trip
Terminal.It is further assumed that being 12 in the actual time of departure of L4:00, and the departure time in plan of travel is 12:40 and reach
Time is 14:00.Based on vehicle in the actual time of departure of L4, vehicle can be predicted in conjunction with operating range and transport information etc.
It is 13 in the time of advent of L5:00.Because the estimated time of advent of L5 is early than the time of advent in plan of travel, this shows car
Can arrive at L5 in advance, so analytic unit 140 judges that this time change does not interfere with nearest charge point B.
(3) no matter whether the actual trip distance of user and time have change, as long as user's vehicle does not fill in specified
Electricity point charges then it is assumed that nearest charge point can be affected.
When nearest charge point is affected, analytic unit 140 makes plan of travel creating unit 110 re-create trip
Plan, and make charging scheme computing unit 120 recalculate charging scheme based on the plan of travel re-creating.
According to the present embodiment, only need to departure time and the distance in future when formulating plan of travel, need not know concrete
Beginning and end so that the formulation of plan of travel becomes simple.By considering the Multiple factors (example in plan of travel
Time of staying of as the distance of each trip, putting at each, the electricity price in corresponding moment, charging modes, charging interval etc.) obtaining
Obtain charging scheme so that charging scheme is more personalized.Additionally, only when actual trip changes and affects nearest charging
Plan of travel and charging scheme is just updated, it is to avoid frequently data renewal during point.
Second embodiment
Fig. 2 shows the block diagram of charging system in accordance with another embodiment of the present invention.As shown in Fig. 2 the present embodiment
In charging system 20 to include plan of travel creating unit 210, charging scheme computing unit 220, monitoring unit 230, analysis single
Unit 240 and user select receiving unit 250.
Similar to the plan of travel creating unit 110 in first embodiment, the plan of travel creating unit in the present embodiment
210 can history trip data based on user, to create plan of travel by way of prediction.In addition, plan of travel creates
Unit 210 can also create plan of travel based on manually entering of user.Alternatively, plan of travel creating unit 210 also may be used
To provide the plan of travel of prediction, then confirmed by user and change partial content.
Charging scheme computing unit 220 can be based on plan of travel, calculate optimum accordingly for each trip cost
Charging scheme.Preferably, trip cost includes charging waiting time, charging modes and charging price in way, etc..
Different from first embodiment, charging scheme computing unit 220 is also based on what plan of travel and user selected
Trip cost is calculating charging scheme.Specifically, user's selection receiving unit 250 can be with receive user to for calculating charging side
The selection of the trip cost (for example charge in way waiting time, charging modes or charging price) of case, is then based on selected
The trip cost that plan of travel and user select is calculating corresponding charging scheme.
Correspondingly, user's selection receiving unit 250 can be with receive user to one or more of multiple charging schemes
The selection of charging scheme, thus monitoring unit 230 can monitor the actual trip of user simultaneously and user selects one or
Multiple charging schemes.Monitoring multiple charging schemes means that user has multiple alternative fill in current course continuation mileage
Electric, different charge point can make different charging cost optimizations, and user can on the way determine to select specifically to charge
Point.
Additionally, in the trip of user, analytic unit 240 can be reminded and used based on the charge point in multiple charging schemes
The nearest charge point in family and last charge point in current course continuation mileage, and the corresponding cost of these charge point.When
Last charge point in front course continuation mileage means that this is that user can make certain charging cost optimized last
Charger meeting.
When finding that user is charged in certain charge point, then analytic unit 240 makes plan of travel creating unit 210 weight
New establishment plan of travel, and it is many accordingly so that charging scheme computing unit 220 is recalculated based on the plan of travel re-creating
Individual charging scheme.
For example, table 3 below gives an example of multiple charging schemes that charging scheme computing unit 220 is calculated.
Table 3
If but user is not charged the distance of actual trip or time and original trip in other charge point
Plan has deviation, then analytic unit 240 judges whether this deviation affects all charge point in current course continuation mileage.If these
Charge point is all affected, then update plan of travel and charging scheme, otherwise reminds which charge point of user becomes unavailable, and
Continue to monitor remaining charge point.
For example, it is assumed that monitoring unit 230 monitors 3 charging scheme 1-3 shown in table 3 simultaneously.With the traveling of vehicle,
Analytic unit 240 may remind the user that last charging in the next charge point and current course continuation mileage that will reach
Point.Assume that charge point C is last charge point in current course continuation mileage in this example.
If the user while being charged when charge point A, then need to update charging scheme, otherwise continuing monitoring and using
The trip at family.In the case of the trip distance that actual trip distance is more than in plan of travel：
If -- impact charge point B, but do not affect charge point C, then remind user's charge point B unavailable, continue prison
Control charge point C.
If -- impact charge point B and C, then charging system can re-create plan of travel and calculate new charging side
Case.
In the present embodiment, such as cheapest can be filled according to the different multiple charging schemes of trip cost creation
Electric scheme, the best charging scheme of charging quality, etc..User can select wherein one or more to fill according to the hobby of oneself
Electric scheme.When user selects multiple charging scheme, user can determine which to select from multiple schemes in actual trip
Charge point.
The flow chart that Fig. 3 shows charging method according to an embodiment of the invention.As shown in figure 3, method 30 exists
Start at step S310 to execute.
At step S320, plan of travel is created based on travel time and trip distance.Plan of travel can be user
In following one day or the even more plan of travel for a long time of some skies, it can comprise user's following time of each trip and
Distance.Can history trip data based on user create plan of travel by way of prediction it is also possible to be based on user
Manually enter to create plan of travel.Alternatively, may also provide the plan of travel predicted, then confirmed by user and repair
Change.One example of the trip planning generating is as shown in table 1 above.
At step S330, charging scheme is calculated based on plan of travel, this charging scheme includes relevant with charge point
Information.For example, it is possible to the factor such as the distance of the trip that looks to the future, the time of staying in each destination and electricity price, in conjunction with
The demand to charging cost for the user, provides optimal charge point, the percentage ratio charging and the time being spent from overall situation consideration
With price etc., thus calculating the optimum charging scheme (optimum charging scheme) of charging cost.Preferably, optimum charging scheme is full
Enough to lower at least one：In way, the charging interval is the shortest, preferably and charging price is minimum for charging quality.The charging scheme generating
One example is as shown in table 2 above.
At step S340, whether the actual trip of monitoring there is deviation with plan of travel.For example, it is possible to obtain in real time use
The travel time of actual trip of family vehicle and position, whether the actual trip comparing user in real time is consistent with plan of travel.
If there is not deviation ("No" at step S340), method 30 proceeds to monitor.
If actual trip and plan of travel occur deviation ("Yes" at step S340), analysis at step S350 should
Whether deviation affects nearest charge point in charging scheme.As described above, can by determine course continuation mileage, the time of advent or
Whether carry out charging carrying out this analysis in charge point.
If not affecting nearest charge point ("No" at step S350) in charging scheme, method 30 returns to step
Monitoring is continued executing with S340.
If having influence on nearest charge point ("Yes" at step S350) in charging scheme, at step S360 again
Create plan of travel, and charging scheme is recalculated based on the plan of travel re-creating.
Finally, method 30 terminates at step S370.
Alternatively, method 30 is also based on plan of travel, calculates optimum accordingly charging for each trip cost
Scheme, and monitor multiple charging schemes simultaneously.Further, it is also possible to be calculated based on the trip cost that plan of travel and user select
Charging scheme.Specifically, method 30 can receive user (for example be filled in way to the trip cost for calculating charging scheme first
Electric waiting time, charging modes or charging price) selection, be then based on the trip that selected plan of travel and user select
Cost is calculating corresponding charging scheme (in step S330).Correspondingly, can monitor simultaneously user actual trip and
One or more charging schemes (in step S340) that user selects.Monitoring multiple charging schemes means user current
Multiple alternative charge point are had, different charge point can make different charging cost optimizations, and uses in course continuation mileage
Family can on the way determine to select specific charge point.One example of multiple charging schemes is as shown in table 2 above.
Fig. 4 shows the schematic diagram of application scenarios according to an embodiment of the invention.For illustration purposes, exist
Three users 401-1,401-2 and 401-3, network 402 and charging system 403 is shown in Fig. 4 example.However, art technology
Personnel are appreciated that after the teaching having read description the number of user is not limited to three, but can be less than three or big
In three.
In actual trip, user each of 401-1,401-2 and 401-3 can be by car-mounted device to networks
