Reference picture 3, is described in detail to information sharing processing S1.Information sharing processing S1 have step S11~ S13.Step S11~S13 is performed successively.Moreover, step S11 can also be performed after step s 13.
In step s 11, the control unit 22 of each charger receives other charger information.Other charger information are expression The information of the behaviour in service up to the present of the charger.Other charger information be, for example, dump power, net cycle time, Idle elapsed time, charging book setting.Dump power is calculated by following formula.
The charging power sum of exportable electric power-charging part 21 output of dump power=charging part 21
Net cycle time exports the cumulative time of the time of charging power for up to the present charging part 21.When free time passes through Between be since charging part 21 turn into idle condition (state for not exporting charging power) at the time of untill at the time of current Elapsed time.Charging book setting is the presence or absence of charging book setting for being carried out by user.Other chargers letter received Breath is stored in storage part 23.Now, other the old charger information being stored in storage part 23 are eliminated.
According to present embodiment, because other charger information include the information of the behaviour in service of expression up to the present, Therefore, it is possible to relax a part charger deteriorated earlier than other chargers.
In step s 12, the control unit 22 of each charger calculates the dump power of itself charger.In step s 13, respectively The control unit 22 of charger sends itself charger information.Itself charger information is surplus including what is calculated in step s 12 Remaining electric power, net cycle time, idle elapsed time, charging book setting.
Using information sharing handle S1, share charging system 10 whole chargers 11,12 ..., 1n information.
Information sharing processing S1 that Fig. 4 represents to have carried out more than 1 time is later, store in storage part 23 in charger 11 Information an example.Be stored with storage part 23 itself charger information, other charger information, charger 11 it is equal Deng charging setting.Dump power of itself the charger information including charger 11, net cycle time, idle elapsed time, charging Book setting.Other charger information include charger 12 ..., 1n dump power, net cycle time, free time be when passing through Between, charging book setting.In addition, the charger spacing being stored with the storage part 23 of charger 11 on the basis of charger 11 From.Distance is inputted for example in the setting of charging system 10 via input unit 24 by setting operator between charger.
Then, secondary requirements are determined that processing S2 is described in detail by reference picture 5.Secondary requirements determine processing S2 tools There is step S21~S29.Hereinafter, the situation that charger 11 receives charging requirement from electric car is illustrated.
In the step s 21, the control unit 22 of charger 11 calculates not enough electric power using following formula.Not enough electric power=(charging Charging power sum+charging requirement that portion 21 is exported)-exportable electric power
It is 20kW with the charging requirement of the charge port 20a electric cars being newly connected, no for example, being 50kW in exportable electric power In the case of using charge port 20b, 20c, 20d, not enough electric power is -30kW.Even if this represents to export to the electric car newly connected Required 20kW, also can residue 30kW electric power.On the other hand, it is 50kW in exportable electric power, is newly connected with charge port 20a Electric car charging requirement be 20kW, from charge port 20b, 20c, 20d export amount to 40kW charging power in the case of, no Sufficient electric power is 10kW.This represents that lacking 10kW, (10kW is not when wanting to the required 20kW of the electric car output newly connected Foot).
In step S22, the control unit 22 of charger 11 judges whether the not enough electric power calculated in the step s 21 compares 0kW is big.(required charging only can be just exported by the charging part 21 of charger 11 in the case where being unsatisfactory for decision condition In the case of electric power), determine not to other chargers 12 ..., 1n require auxiliary (step S23).On the other hand, meeting In the case of decision condition (in the case of only can not exporting required charging power by the charging part 21 of charger 11), enter Enter to step S24.
In step s 24, whether the control unit 22 of charger 11 judges the not enough electric power calculated in the step s 21 as it His charger 12 ..., below 1n dump power sum.Now, control unit 22 is with reference to storage part 23.It is being unsatisfactory for judging In the case of condition (using other chargers 12 ..., 1n dump power all can not export institute as auxiliary power It is required that charging power in the case of), determine not to other chargers 12 ..., 1n require auxiliary (step S23).Now, Control unit 22 can be passed on to the electric car newly connected can not get started the intention of charging.Thereby, it is possible to prevent from being unsatisfactory for electricity The charging requirement of motor-car, but to other chargers 12 ..., 1n require auxiliary power output situation.On the other hand, exist In the case of meeting decision condition (if using other chargers 12 ..., 1n dump power can be defeated as auxiliary power In the case of going out required charging power), enter step S25.
In step s 25, the control unit 22 of charger 11 determines whether that having carried out impartial charging sets with reference to storage part 23 It is fixed.So-called impartial charging refer to the charger in the output that can carry out auxiliary power exist it is multiple in the case of, fill these Electrical equipment equably exports the charging modes of auxiliary power.Step S26 is entered in the case where not carrying out impartial charging setting, Carry out entering step S27 in the case of impartial charging setting.
In step S26, the control unit 22 of charger 11 be based on other chargers 12 ..., 1n dump power, fill Electric book setting and ranking value, determine that the charger of more than 1 (auxiliary charging device) of auxiliary power should be exported and to each auxiliary Help the auxiliary power of charger requirement.Now, control unit 22 is with reference to storage part 23.
In step S26, the control unit 22 of charger 11 calculates other chargings with reference to storage part 23, and using following formula Device 12 ..., 1n ranking value.
Ranking value=A × elapsed time free time/(distance between B × net cycle time+C × charger)
Herein, coefficient A, B, C is weight coefficient set in advance (wherein, A > 0, B > 0, C > 0).It can be seen from above formula Ranking value increases with the lengthening in idle elapsed time.With the lengthening of net cycle time, also, with distance between charger Change it is big, ranking value reduces.Therefore, the high charger of the ranking value charger lower than ranking value is more suitable for auxiliary charging device.
Then, the control unit 22 of charger 11 by carried out charge book setting other chargers 12 ..., 1n from Excluded in the candidate of auxiliary charging device.Thus, it is to avoid the charger for charge book setting is turned into auxiliary by user Charger, can prevent from cannot respond to the situation of charging reservation.
Then, the control unit 22 of charger 11 be not excluded other chargers 12 ..., dump power is most in 1n Many chargers (such as charger 12) are used as auxiliary charging device.Then, determine in the range of dump power to auxiliary charging Device requires the output of auxiliary power., can be by from filling in the case where the dump power of charger 12 is more than not enough electric power The not enough electric power of the auxiliary power supplement whole of electrical equipment 12.In this case, as previously discussed, step S26 terminates.The opposing party Face, in the case where the dump power of charger 12 is less than not enough electric power, is merely able to using the auxiliary power from charger 12 A part for supplement deficiency electric power.In this case, determine also to the other chargers 12 not being excluded ..., in 1n only The charger (such as charger 13) more inferior to the dump power of charger 12 requires auxiliary electricity in the range of dump power The output of power.
The equal other chargers 12 of dump power ..., 1n be more than 2 in the case of, it is high with ranking value Charger is preferentially used as auxiliary charging device.For example, in the (dump power of charger 12:50kW, ranking value:7), charger 13 is (surplus Remaining electric power:40kW, ranking value:6) with (dump power of charger 14:40kW, ranking value:8) it is the feelings for the candidate for aiding in charger Under condition, first, auxiliary charging device is used as using charger 12.Only it can not supplement whole by the dump power of charger 12 In the case of not enough electric power, second auxiliary charging device is used as using charger 14.Even if by charger 12 and charger 14 Dump power is added in the case of can not supplementing whole not enough electric power, is further used as the 3rd auxiliary using charger 13 Charger.
In step s 27, the control unit 22 of charger 11 judge other chargers 12 ..., 1n dump power it Whether sufficiently large for not enough electric power (for example whether dump power sum is more than 2 times of not enough electric power).Now, Control unit 22 is with reference to storage part 23.In the case where being unsatisfactory for decision condition, be not suitable for carrying out impartial charging, or can not carry out The possibility of equalization charging is very high.Therefore, step S26 is performed, auxiliary charging device and auxiliary power is determined.In this case, no Carry out impartial charging.On the other hand, in the case where meeting decision condition, step S28 is entered.
In step S28, the control unit 22 of charger 11 will carry out other chargers of charging book setting 12nd ..., 1n and dump power for 0kW other chargers 12 ..., 1n excludes from the candidate of auxiliary charging device. Then, control unit 22 using the other chargers 12 not being excluded ..., 1n as auxiliary charging device, determined using following formula auxiliary Help electric power.
The quantity of auxiliary power=deficiency electric power/auxiliary charging device
Using impartial charge function, the behaviour in service of each charger can be made more impartial.
In step S29, the decision based on step S26 or step S28 sends secondary requirements to auxiliary charging device.
Then, the action example to the charging system 10 of present embodiment is illustrated.Moreover, in following each action example In, the quantity n of charger is 4, and the exportable electric power of the charging part 21 of each charger 11,12,13,14 is 50kW.In action In example 1,2, impartial charging setting is not carried out to charger 11.In action example 3,4, impartial charging is carried out to charger 11 and has been set It is fixed.Herein, the condition for carrying out impartial charging is that the dump power sum of other chargers is more than 2 times of feelings of not enough electric power Condition, in the case of less than 2 times even if carried out it is impartial charging setting also without equalization charging.
