Abstract

In a charging apparatus, when current flowing through a main circuit breaker (110) exceeds its current capacity, the charging current regulating part (24) causes a communication part (25) to transmit a regulating command of descending the present upper limit value of a charging current. When receiving the regulating command from the charging current regulating part (24), the charging control part (14) of the charging unit (10) changes the duty ratio of the pilot signal to a new duty ratio corresponding to the upper limit value indicated by the regulation command, and descends the upper limit value of the charging current. Consequently, the charging current supplied to each electric vehicle is decreased, whereby the current of the main circuit breaker (110) is avoided from exceeding its rated current. Accordingly, multiple electric vehicles can be charged concurrently while suppressing influence of power supply to electrical appliances other than the electric vehicles.

Meanwhile, to electro-motor Vehicular charging, conventionally need to there are a large amount of charging currents of approximately ten to tens of amperes.In general house or office, the rated current of main circuit breaker 110 (when being provided with amplitude limiter, being amplitude limiter and main circuit breaker 110) is set to approximately 30 to 80 amperes.Thereby, in the situation that a plurality of electro-motor vehicles are charged when being used as the electrical equipment of load simultaneously, there is the problem that for example principal current trips main circuit breaker 110 or amplitude limiter over rated current in the situation that another charhing unit 10 newly starts charging.
Thereby, in the situation that flow through the principal current of main circuit breaker 110, surpass its current capacity (rated current of main circuit breaker 110), the charging current adjusting portion 24 of control unit 20 makes Department of Communication Force 25 send order (adjusting command), and the higher limit of this adjusting command charging current is set to lower than currency.
Charging current adjusting portion 24 checks by the detected charging current value of current detecting part 23 whether each charhing unit 10 is in charge mode.The quantity M of the charhing unit 10 of acquisition under charge mode, and calculate the summation of the load current that the load except charhing unit 10 consumes.Finally, charging current adjusting portion 24 by by the difference between the current capacity of main circuit breaker 110 and load current summation divided by the quantity M value of calculating.In addition the higher limit that, charging current adjusting portion 24 is determined charging current is so that it is no more than the value (=(the electric current capacity – load current summation of main circuit breaker 110)/M) calculating.In other words, the whole charhing units 10 under charge mode are adjusted to and have identical higher limit.
For example, suppose at three charhing units 10 in charge mode and have under the state of higher limit of 20A, another charhing unit 10 newly starts charging, and the electric current of main circuit breaker surpasses its current capacity.In current capacity, be 60A and load current summation be 0A in the situation that, charging current adjusting portion 24 determines that (after adjusting) higher limit for being not more than the current value of 15A (by 60A is obtained divided by 4), for example, is 13A.Then, charging current adjusting portion 24 makes Department of Communication Force 25 that adjusting command is sent to four charhing units 10, and wherein this order higher limit is set to 13A.
In charhing unit 10, Department of Communication Force 15 receives the adjusting command of sending from control unit 20 and sends it to charging control section 14.Charging control section 14 receives from the adjusting command of charging current adjusting portion 24 and by the duty ratio of pilot signal and changes into the corresponding new duty ratio of the higher limit indicated with adjusting command.
The new current value of the higher limit replacement charging current of the charging ECU of electro-motor vehicle based on after regulating also exports charge command to battery charger.Received the battery charger of charge command in the situation that regulate its charging current so that be no more than the set new current value of charging ECU to charge in batteries.Therefore, the charging current that is supplied to each electro-motor vehicle reduces, and avoids thus the principal current of main circuit breaker 110 to surpass its rated current.In other words, according to the charging device of the present embodiment, can be in the situation that suppress the impact of the electric power supply of the household electrical appliances except motor vehicle (lighting device, air-conditioning etc.) a plurality of motor vehicles (electro-motor vehicle) to be charged simultaneously.
Yet in the situation that complete the charging of some charhing unit 10, charging current adjusting portion 24 can also regulate charging current higher limit so that its increase according to the quantity of the charhing unit 10 under charge mode.
Meanwhile, in the situation that charging current adjusting portion 24 regulates the higher limit of charging current, all higher limits of a plurality of charhing units 10 do not need identical.For example, due to the specification of the battery charger of electro-motor vehicle, charging current higher limit may be difficult to be set to lower than 6A.In the case, charging current adjusting portion 24 is preferably at least one charhing unit 10 under charge mode is stopped to charging (higher limit is set to 0A).In other words, can reduce the quantity of the charhing unit 10 that will simultaneously charge.Thereby, for the charhing unit 10 that continues to charge, more than the higher limit of its charging current can be set to 6A.Now, be preferably charhing unit 10 that per scheduled time of charging current adjusting portion 24 makes to stop charging alternately.
Or in the situation that priority orders being distributed to a plurality of charhing unit 10, the higher limit that is preferably the charhing unit 10 with higher priority is set to relatively higher.In other words, in the situation that the principal current of main circuit breaker surpasses its current capacity under the charge mode of three charhing units 10, except having the charhing unit 10 of limit priority, charging current adjusting portion 24 reduces the higher limit of all the other two charhing units 10.For having the charhing unit 10 of limit priority, charging current adjusting portion 24 does not change its higher limit.Under this mode, compare with utilizing other electro-motor vehicle of other charhing unit 10 chargings, utilize the electro-motor vehicle that specific charhing unit 10 (charhing unit 10 with limit priority) charges to charge with the shorter time.
Meanwhile, as shown in Figure 4, in any one that can be in charhing unit 10, communication control unit 16 is set but not Department of Communication Force 15, and all Department of Communication Force 15 or communication control unit 16 can be set in all other charhing units 10.Communication control unit 16 will be sent to each charging control section 14 of all other charhing units 10 from the received adjusting command of control unit 20 (information of higher limit).This has eliminated the necessity that Department of Communication Force 15 is set in all other charhing units 10, reduces thus the manufacturing cost of charhing unit 10.
