As shown in Figure 1, the electric vehicles charging system of present embodiment possesses charging device 1 and electric power monitoring device 2.
Electric power monitoring device 2 possesses control part 20, current measurement portion 21, Department of Communication Force 22 etc.The electric current of two electric wires beyond the neutral line that current measurement portion 21 uses current sensor 210,211 to measure to flow through in three electric wires be connected with the primary side of main breaker 40 respectively, outputs to control part 20 by each measured value.Control part 20 with microcomputer for main inscape, according to the measured value (magnitude of voltage) of the primary side voltage (input voltage) of the current value measured by current measurement portion 21 and main breaker 40, calculate the instantaneous value, aggregate-value etc. of the electric power (supply electric power) supplied from electric power system 100.In addition, Department of Communication Force 22 communicates between charging device 1, such as, carry out the serial communication according to RS485 standard.But the communication mode of Department of Communication Force 22 is not limited to RS485 standard, also can be power line carrier communication, radio communication (such as low-power wireless communication etc.) etc.
Charging device 1 possesses signal processing part (delivery unit) 10, zero phase current transformer 11, detection of electrical leakage portion 12, opening/closing portion 13, communication control unit (adjustment unit) 14, charge cable 15, charge connector 16 etc.In addition, charging device 1 is arranged on the place of the parking space (garage) close to electric automobile 200, is connected with one of the branch circuit of branch circuit breaker 41 branch by house dish 4 (being the branch circuit breaker 41 of bottom righthand side in FIG).About charge cable 15, flow through and wrapped up by insulating sleeve to the supply lines 150 of the supply electric current (charging current) of electric automobile 200 and the conveyer line 151 of transmission pilot signal described later (pilotsignal), fore-end is provided with charge connector 16.Charge connector 16 plugs the insert port (inlet) inserted freely and be connected to the car body being arranged at electric automobile 200.And, when charge connector 16 insertion is connected to insert port, electric power (charging power) can be supplied from electric power system 100 via house dish 4 and charging device 1, and pilot signal can be transmitted between the signal processing part 10 of charging device 1 and charging ECU (electronic control unit) (not shown) of electric automobile 200.
Opening/closing portion 13 possesses the electromagnetic relay (not shown) be inserted into from branch circuit breaker 41 to the supply line of supply lines 150, by correspondingly making electromagnetic relay close or disconnect with the instruction from signal processing part 10, come the above-mentioned supply line of opening and closing.The unsymmetrical current flowing through supply line is detected in detection of electrical leakage portion 12 by zero phase current transformer 11, be judged as creating electric leakage when the detection level of this unsymmetrical current exceedes threshold value, controls opening/closing portion 13 Lai Shi supply line and disconnects.Communication control unit 14 has: the function (communication function) of carry out communicating between the Department of Communication Force 22 of electric power monitoring device 2 (serial communication of RS485 standard); And adjust the function (adjustment function) of the charging current supplied to electric automobile 200 as described later.Such communication control unit 14 is made up of the integrated circuit etc. of microcomputer and serial communication.In addition, in electric power monitoring device 2, the electric current (charging current) supplied to electric automobile 200 via charging device 1 is measured by current sensor 212.
At this, the sequential chart with reference to Fig. 3 illustrates the basic charging action of charging device 1.First, when charge connector 16 being connected to the insert port of electric automobile 200 at moment t0, apply the voltage V1 (such as V1=12 volt) of regulation from signal processing part 10 to conveyer line 151.And, the voltage being applied to conveyer line 151 becomes the transmission medium controlling pilot tone (CPLT) signal (hereinafter referred to as pilot signal), and its voltage level and duty ratio correspondingly receive and dispatch various information as described later between charging ECU and signal processing part 10.
The voltage level of pilot signal, when the pilot signal of voltage V1 being detected, is depressurized to V2 (such as V2=9 volt) (moment t1 ~ t2) from V1 by charging ECU.Signal processing part 10, when detecting that pilot signal is reduced to V2 from V1, exports the pilot signal (moment t2 ~ t3) of the pulse type of assigned frequency (such as 1kHz).The signal level of this pilot signal is ± V1, but boundary level is depressurized to V2.The duty ratio of pilot signal represents and the higher limit (current capacity of charging device 1) of charging current presets for each charging device 1.Such as, when current capacity is 12 amperes, duty ratio is set as 20%, when current capacity is 30 amperes, duty ratio is set as 50%.When charging ECU identifies current capacity detecting the duty ratio of pilot signal, the voltage level of pilot signal is depressurized to V3 (such as 6V) (moment t3) from V2.Signal processing part 10, when detecting that the signal level of pilot signal is reduced to V3 from V2, makes opening/closing portion 13 close to start the supply of charging power.
Charging ECU sets the current value (≤current capacity) for the charging level of storage battery being charged to target level according to current capacity, exports charging instruction to the charger be equipped in electric automobile 200 (not shown).Receive the charger of charging instruction while adjustment charging current makes it be no more than current value set by charging ECU, (moment t3 ~ t4) is charged to storage battery.When the charging level of storage battery reaches target level, charging ECU terminates the charging to storage battery to charger output charging END instruction, makes the voltage level of pilot signal revert to V2 (moment t4) from V3.Charger, when receiving charging END instruction, terminates the charging of storage battery.
Signal processing part 10, when detecting that pilot signal is changed to V2 from V3, makes opening/closing portion 13 disconnect the supply stopping alternating electromotive force.Charging ECU makes the voltage level of pilot signal revert to V1 (moment t5) originally.Signal processing part 10, when the voltage level of pilot signal reverts to V1, stops the vibration of assigned frequency, the voltage level of pilot signal is maintained V1 to revert to holding state (moment t6).
As described above, charging device 1 is switched on or switched off the supply of the charging power to electric automobile 200, and indicates the higher limit of charging current to the charging of electric automobile 200 with ECU, controls the charging being equipped on the storage battery of electric automobile 200 thus.
But, in the charging of electric automobile 200, usually need the large charging current of tens amperes ~ tens Amps.On the other hand, in ordinary residence, the rated current of main breaker 40 (being flow restricter and main breaker 40 when being provided with flow restricter) is set to 30 amperes ~ 60 Amps.Therefore, when electric automobile 200 being charged when using electromagnetic cooker, the such current sinking of air-conditioning large load equipment, if flow through charging current to reach in advance to the higher limit that charging device 1 sets, then main breaker 40, flow restricter is caused to trip.
Therefore, the control part 20 of electric power monitoring device 2, when the electric current (wastage in bulk or weight electric current) flowing through main breaker 40 exceedes rated current, makes to send from Department of Communication Force 22 instruction (adjustment instruction) higher limit of charging current being set to and deducting the current value of the difference gained of wastage in bulk or weight electric current and rated current from the current value of current charging current.In addition, wastage in bulk or weight electric current is the summation of the current sinking (load consumed current) of charging current and load equipment.Then, the control part 20 of electric power monitoring device 2, when wastage in bulk or weight electric current is lower than rated current, can also make to be sent in from Department of Communication Force 22 instruction improving the higher limit of charging current in limit that wastage in bulk or weight electric current is no more than rated current.At this, in the limit of the current capacity of the charging device 1 that each charging device 1 is preset, improve the higher limit of charging current.But, control part 20 is when can roughly see zero as by the charging current measured by current measurement portion 21 (electric current detected by current sensor 212), be judged as not charging in electric automobile 200, do not carry out the notice of the adjustment instruction of higher limit.
In charging device 1, the communication control unit 14 receiving the above-mentioned adjustment instruction sent from electric power monitoring device 2 carries out indicating below the higher limit that makes the higher limit of charging current to be set to by adjustment instruction instruction to signal processing part 10.Then, signal processing part 10, when receiving the instruction from communication control unit 14, makes the duty ratio of pilot signal reduce.Such as, when the current capacity of charge cable 15 is 20 amperes, be that the duty ratio of 50% reduces to 40% ~ 20% originally, result, the higher limit of charging current is adjusted to than ampere low value of 20 originally (such as 10 amperes).
The charging ECU of electric automobile 200 sets the current value of charging current again according to the higher limit after adjustment, and exports charging instruction to charger.Receive the charger of this charging instruction while adjustment charging current makes it be no more than new current value set by charging ECU, storage battery is charged.Its result, the charging current supplied to electric automobile 200 reduces, therefore, it is possible to avoid wastage in bulk or weight electric current to exceed the situation of the rated current of main breaker 40.
But, as illustrated in the prior art, making minimizing charging current play reality till charging current is reduced in electric automobile 200 side from carrying out instruction by charging device 1 to electric automobile 200, quite long time of delay can be produced.Such as, as shown in (b) of Fig. 2, if suppose from being received the time needing T2 till the duty ratio changing pilot signal is played in adjustment instruction by communication control unit 14, to electric automobile 200 and pilot signal correspondingly reduce charging current, need the time of T3, then produce the delay of T1 time (=T2+T3).Its result, at least continues T1 and flows through overload electric current temporally, therefore, when time of delay, T1 exceeded tripping operate time, likely cause main breaker 40 to trip in main breaker 40.Further, according to the vehicle of electric automobile 200, the situation that time T3 required to electric automobile 200 correspondingly reduces charging current from pilot signal is different is many.
Therefore, in the present embodiment, at signal processing part 10 according in the situation (situation of minimizing) of the duty ratio of adjustment modification of orders pilot signal, by signal voltage being set to after zero volt temporarily stops pilot signal (after the T5 time), pilot signal is sent to the charging ECU ((a) with reference to Fig. 2) of electric automobile 200 with the duty ratio after change.The charging ECU of electric automobile 200 makes charger stop charging immediately when pilot signal stops, receiving pilot signal, again setting the current value of charging current according to the higher limit after adjustment, and export charging instruction to charger after the T5 time.Receive the charger of this charging instruction while adjustment charging current makes it be no more than new current value set by charging ECU, storage battery is charged.In this case, the T6 time is needed from being received by charging ECU pilot signal plays again till charging current.
So, when pilot signal is temporarily stopped as described above, the time that wastage in bulk or weight electric current exceedes rated current is only time T4 required till signal processing part 10 stops pilot signal, is not subject to the impact of the processing time T3 in electric automobile 200.Therefore, charging device 1 according to the present embodiment, can independently avoid the tripping operation of main breaker 40 with the kind of electric automobile 200, and charging current is adjusted to suitable value.
But, when starting the charging from charging device 1 pair of electric automobile 200, when the value higher limit of charging current being set as determine according to the current capacity of charging device 1 (hereinafter referred to as limit value substantially), according to the current value of load consumed current, and then charging start after wastage in bulk or weight electric current likely exceed rated current.Therefore, preferably, when starting to charge, signal processing part 10 makes the duty ratio of pilot signal increase in certain proportion, makes higher limit be increased to limit value (with reference to Fig. 4) substantially gradually from the higher limit lower than limit value substantially.And when the rising midway wastage in bulk or weight electric current of higher limit has exceeded rated current, signal processing part 10 is according to the instruction from electric power monitoring device 2, and the duty ratio of adjustment pilot signal makes to reduce higher limit.
Be inserted into as described above between circuit breaker and motor vehicle in the electric vehicles charging device of the higher limit of above-mentioned motor vehicle instruction charging current, preferably possess: delivery unit, it transmits the information of above-mentioned higher limit between above-mentioned motor vehicle by voltage signal; And adjustment unit, it indicates the adjustment of above-mentioned higher limit according to the current value of the electric current flowing through above-mentioned circuit breaker to above-mentioned delivery unit, wherein, above-mentioned delivery unit makes above-mentioned higher limit rise gradually when charging and starting.By like this, the tripping operation of the circuit breaker (main breaker 40) charged when starting reliably can be avoided.
At this, mutually can combine the content of above-mentioned execution mode.
Above, describe the preferred embodiment of the present invention, but the present invention is not limited to these specific execution modes, can not depart from various change and the distortion of the category of claims, it also belongs in category of the present invention.
