Electrical equipment 251a, 251b, 252b, the 255a in 253b(or Fig. 3 is to 255n) can be electric device (for example, washer, dryer, air-conditioning, stove, baking box, heater, etc.), it is from service power circuit 22 current drawn.
Electrical power services panel 24 also comprises family expenses residual current device (RCD) 27, and it is common in electric appliance branch road 25a and 25b(Fig. 3 and is marked as 25a/b), and be arranged on the downstream of main circuit breaker 23.Electrical power services panel 24 further comprises that the one or more electric apparatus circuit breaker 28a that are arranged in electrical equipment branch road 25a and 25b and 28b(are referring to Fig. 2), correspondingly, it is coupled to main circuit breaker 23 by family expenses residual current device (RCD) 27.

According to the application's embodiment, according to dynamic current limit algorithm (DCLA), the electric current of being drawn by charge point 21 is controlled, this dynamic current limit algorithm (DCLA) is provided for dynamically adjusting according to total house current drain the instruction of charging current.For fear of stopping in high electrical load in the situation that charging, DCLA considers that each conventional electric circuit breakers can be by a current-time characteristic (profile) characterization, this current-time characteristic defined in the situation that higher than the given current value of nominal/allowance current limit by the special time restriction of house electric grid operating.In other words, the certain overcurrent that is greater than nominal/allowance current limit (being called again allowable deviation herein) is still allowed by circuit-breaker, but is to be only allowed in a scheduled time slot.
Yet, when surpassing this time restriction, circuit-breaker will trip (or fuse burns).For example, when current loading is 135%, electrical network can operating about one hour, main circuit breaker trip, but when current loading reaches 145%, the time restriction operating under the prerequisite that electrical network does not trip at main circuit breaker can be reduced to about 0.5 hour.It should be noted, the current-time characteristic of circuit-breaker is typically associated from certain standard (it is different in different countries).It should be noted, traditional circuit-breaker has conventionally can be apparently higher than nominal current (for example, sometimes in nominal, permit the magnitude of three times to ten times of electric current, this depends on the type of used circuit-breaker) tripping current, this causes that instant (for example,, within the period of about 100 milliseconds) electric current turn-offs.
In order to control and to regulate by the electrical equipment (251a in Fig. 2,251b, 252b, 255a-n in 253b and Fig. 3) and total electric energy of consuming of charge point 21, house electric power system 20 comprises control system 290, and this control system 290 is used for controlling the electric current that can draw to the charge point 21 of the battery 210b charging of motor vehicle 210.For example, when the magnitude of current of being drawn by all electrical equipment and charge point surpasses the admissible nominal current restriction of main circuit breaker 23, if control system roughly remains unchanged estimation wastage in bulk or weight electric current, so main circuit breaker will how long (time quantum T
trip) tripping operation afterwards, and the allowance duration T (T<T carrying out under the prerequisite that correspondingly definite charging process can not trip at main circuit breaker
trip).Once permitting duration T under the prerequisite at wastage in bulk or weight electric current without any reduction exhausts, control system 290 is adjusted the electric current of being drawn by charge point 21, thereby guarantee that the total current consuming by service power circuit 22 is no more than the nominal allowance current limit of this allowance, and then avoid main circuit breaker 23 tripping operations.
In other words, whenever being greater than nominal, the measured total current of passing through main service electric line 22 consumption permits current limit, but in the time of in predetermined allowable deviation electric current, controller 290 is analyzed the total current of measured consumption, and correspondingly determines the specific allowance period T that is allowed to proceed by identical charging load charging process.The allowance period of being determined by controller 290 need to be shorter than the response time (T of main circuit breaker to concrete measured wastage in bulk or weight electric current
trip), to prevent current interruptions (tripping operation).
If charge point 21 is connected to electrical network by the illustrative cascade configuration type of Fig. 3, and measured process feeder line 22a, 22b,., the total current that one of 22n consumes is greater than nominal and permits current limit, but in predetermined allowable deviation electric current, controller 290 is determined specific allowance period T for corresponding upstream main circuit breaker, and use this specific allowance period T to carry out timing, in this specific allowance period T, charging current can continue under the prerequisite that does not change charging load.
If measured, pass through feeder line 22a, 22b,., two or more total current in the total current that 22n consumes is greater than nominal and permits current limit, but in predetermined allowable deviation electric current, controller 290 is determined specific allowance period T for corresponding upstream main circuit breaker, and uses the determined minimum period T of allowance to carry out timing.For example,, if measured feeder line 22a, the 22b of passing through,., all total currents in the total current that 22n consumes are all greater than its corresponding main circuit breaker 23a, 23b ...., the nominal current restriction of 23n, but in its corresponding predetermined allowable deviation electric current, controller 290 is each corresponding upstream main circuit breaker 23a, 23b,., 23n determines corresponding specific allowance period T
a, T
b..., T
n, and use the determined minimum allowance period, that is, and minimum (T
a, T
b..., T
n) carry out timing, in this minimum is permitted the period, charging current can continue under the prerequisite that does not change charging load/electric current.
If measured, pass through feeder line 22a, 22b,., one or more total currents that consume of 22n are greater than its corresponding main circuit breaker 23a, 23b,., the allowable deviation electric current of 23n, low consumed charging current falls in controller 290 indication charge point 21, or alternately, indication charge point 21 disconnects charging current, until the electric current in measured feeder line allows charging process to restart.
If during allowing the timing of duration T, the total current consuming in any one in feeder line increases, still in allowable deviation electric current, control system 290 can operate in following operation with measured electric current: determine that new allowance duration T is with correspondingly for timing; Indication charge point 21 reduces the charging current being consumed by charge point 21; Or alternately, stop/pause charging process, until house power consumption allows charging process to restart.Control system 290 can be drawn together for supervisory packet the charging process of a plurality of charge cycles, and as described in Israel patent application No.218213 as identical in the assignee with the application, the disclosed content of this patent application is incorporated to herein as a reference.
For this reason, control system 290 can be for carrying out following operation:
(a) optimize and suspend (at interval, charging process temporarily stops) number of times, to charge the battery under the prerequisite not tripping during charging process at main circuit board.For example, the suspending count that control system can limit permission is no more than the minimum number of permission, otherwise charging process can be stopped by the charge controller of vehicle;
(b) during charging process, maximize charging current value (reaching a particular maximum value);
(c) alternatively, (i) charging process is notified to the user to charge point, comprise that for example charging process is interrupted due to the operation of another electrical equipment, and (ii) charging current is notified to the operator to electrical network, thereby make electrical supplier can manage overall electric grid operating when needed.
In operation, response is made in the variation of 292 pairs of electric currents of being drawn by all electricity consumption branch roads of controller circuitry, and for generating the control signal for current regulator 291, for the electric current that adjustment is drawn by charge point 21 according to dynamic current limit algorithm.
According to embodiment, DCLA comprises two kinds of operator schemes:
Normal mode, the total house current drain in feeder line 230 lower than or for example, while equaling the admissible nominal current of circuit-breaker restriction (25A).In normal mode operating period, as long as need, can continue charging process with the maximum charging current in charge point; And
Cross stream mode, the total house current drain in feeder line 230 is greater than nominal current restriction (for example, 25A), but for example, while being less than or equal to allowable deviation electric current (, 25A * 1.13=28A).It should be understood that in the case, the charging process of carrying out with overcurrent (that is, being greater than nominal current restriction) in feeder line 230 is sustainable certain period only.After this period finishes, controller circuitry 292 produces control signal, and this control signal is adjusted the electric current of being drawn by charge point for (for example,, by current regulator 291), so that total house electric current is no more than nominal current restriction, thereby avoid main circuit breaker 23 tripping operations.
According to some embodiment, the maximum of the available charging current that current regulator 291 can be drawn vehicle is notified to motor vehicle 210, and motor vehicle 210 correspondingly responds by adjusting its maximum current consumption.According to another alternative of the present utility model, at measured wastage in bulk or weight electric current, be greater than nominal current restriction, but in allowable deviation electric current, and in the too slow situation of the Expected Time Of Response of vehicle 210, the controller 292 of charge point 21 can cut out simply and offers the supply of electric power 26 of vehicle 210 and send signal with indication disconnected event to vehicle 210.Then, can restart charging process with the charge-current limit reducing.
Usually, system can be for to the imitate/emulation of the current-time characteristic of analog circuit circuit breaker, and the maximum current that can be consumed by charge point under the prerequisite not tripping at circuit breaker with enough confidence level predictions.
The special module of traditional house electric power system that it should be understood that control system 290 can be integrated.According to some embodiment, the current regulator 291 of control system 290 and controller circuitry 292 are positioned at charge point 21 places, and current sensing element 293 is positioned at electric power panel 24.In this configuration, be sent to the electric current that the data of charge point 21 are not consuming, but for the current drain allowing of charge point 21 own.Charge point 21 then has to strengthen in the following way this restriction: new current limit is notified to vehicle 210, or (for example, by current regulator 291) regulate and to be supplied to the electric current of vehicle, or cut off together charging current supply.When needed, some elements in control system 290 (for example, controller circuitry 292 and current regulator 291) can be positioned at the outside of electrical power services panel 24.In this example, as shown in Figure 2, controller circuitry 292 is positioned at charge point 21.
In certain embodiments, CSE293 is independent device, for monitoring the electric current of the feeder line 230 that is monitored of flowing through, and the data that represent the electric current of the feeder line 230 by being monitored is sent to the control system 290 being associated with long-range charge point 24.Described data can be used the wireless transmission of standard radio data transmission technology (for example WLAN or Zigbee), or through wire communication link (for example, pulse-width modulation, and/or use any traditional serial or parallel data bus communication) transmit, or can use standard electric line of force communication (PLC) technology to complete transmission by main line.
The circuit that CSE293 can be monitored by direct measurement (with it series connection) or for example, by indirectly measuring (, magnetic field induction), come monitoring and measuring to flow through the electric current of the feeder line being monitored.In the situation that directly measuring, CSE293 measures the electric power from answering with the direct-heating system of main line.In the situation that indirectly measuring, induced current can be used to the operation power of CSE293 device.Yet, in both cases, also can use external power supply (for example, battery) as alternative.
According to some embodiment of the application, CSE293 can be for periodically sampling by being monitored the electric current of circuit, and correspondingly periodically to send the data that represent sample rate current.In this kind of possible embodiment, one way data communication can be enough for regulating the charging power that is supplied to charge point 21.
In other embodiment of the present utility model, CSE293 carries out dynamic sampling for the electric current that process service power circuit 22 is consumed, and sends corresponding designation data in response to one or more trigger events.In this kind of possible embodiment, may need two-way communication.If trigger event does not have repetition period property, method is frequent, uses this kind of event (that is, the method based on triggering) to be considered as more efficient aspect power consumption.
For example, trigger event can comprise following event:
Charge point poll, it is corresponding to following situation: the maximum charge power that charge point 21 for example needs change to be drawn by motor vehicle due to electrical network restriction, therefore this may need charge point 21 inquiry CSE293, for measuring electric current by feeder line 22 (" can operating current ").
CSE interrupt event, it is corresponding to following situation: charge point 21 can arrange for CSE293 the triggering of a definition current strength threshold value, so that whenever the electric current by feeder line 22 is greater than predefine threshold value, CSE293 can send to charge point by the data that represent sample rate current, thereby allows the control system 290 being associated with charge point 21 dynamically to respond any increase in the total current drain of household electrical appliance.
In a comparable manner, charge point 21 can arrange threshold value, and when lower than this threshold value, CSE293 need to convey to charge point 21.This allows charge point 21 dynamically to respond the minimizing of total domestic load.
According to embodiment more of the present utility model, CSE293 can be for determining current strength with following variety of way based on current sample, for example, calculate the mean value of the current indication of sampling within the predefined period, or indicate the maximum current reading of sampling within the predefined period.Above-mentioned for determining that each (CSE293 operates based on this) of the technology of current strength makes charge point 21 can improve the utilization rate of its net capacity under different situations.
According to some embodiment of the application, CSE293 and charge point 21 can comprise the function of measurement result being charged to daily record, this daily record can be sent to central server or control centre subsequently, for the electrical network of management supply electric power or any other accreditation body.Daily record data can be born a large amount of load characteristics and dissect (profiling) and gridding information.
The a kind of of CSE293 may realize the conventional modification that can use power circuit technology, to comprise the reflector that is operated and sent fixed carrier signal by induction.The frequency of carrier signal can be shifted, and can proportional with the electric current that flows through wire (that is, current sensing signal being taked the frequency modulation(FM) of carrier wave).The circuit of CSE293 can be powered from induced current, does not therefore need any physical connection of wire, and can use around the foreskin realization of the existing wire of circuit 230.In the case, if in the wire being associated with circuit 230 no current flows or only have very little current flowing, the reflector of CSE293 does not send any signal.
Receiver end is associated with regulating the control system 290 of the operation of charge point 21.Electric current in control system 290 sensing supply lines 230, and detect the carrier frequency from the signal of CSE293.The frequency of signal that therefore, can be based on receiving from CSE293 is estimated current loading.
According to some embodiment of the application, CSE293 is the device that comprises measuring component, simple controller and power line communication (PLC) interface with current sensor.The supply of electric power of this device is from single-phase direct-connected driving, modulated for communicating by letter with charge point to PLC signal based on this.
Referring now to Fig. 4, the flow chart 300 shown in it for example understands the process that regulates the charge power in the network system that adopts charge point 21.In this example, suppose that battery and the direct electrical connection of charge point 21 in vehicle 210 are established.In step 301, by measuring or record total house current drain I
cstart charging process.Then in step 302, according to measured total current drain I
cdetermine and permit charging current level.
Conventionally, in step 302, determine to permit charging current and draw maximum charge power to allow charge point and/or to be connected under the prerequisite that the controller of the vehicle of this charge point do not trip at main circuit breaker 23.Then in step 303, by permitting charging, supply the controller 210 that is sent to charge point 21 and/or vehicle, correspondingly to regulate charging.In this stage, charge point 21 and/or vehicle control device 210 are according to the instruction adjustment charging supply sending in step 302, so that the charging current of drawing is no more than allowance level definite in step 302.
Charging process is then proceeded, and in step 304, to total current drain, I measures again, to check the electric current I that wastage in bulk or weight electric current I is measured before whether being greater than in step 301 in step 305
c.If work as the current drain of pre-test lower than the electric current I of measuring before
c, control is got back to step 301 to 303, to determine new allowance charging level of supply, and indicate charge point 21 and/or vehicle control device 210 correspondingly to regulate charging current.Follow the test of repeating step 304 and 305 to check whether wastage in bulk or weight electric current I is greater than the electric current I of measuring in step 301
c.
If determine that wastage in bulk or weight power current I is greater than the electric current I of measuring before
c, in step 306, check whether measured electric current I is greater than the maximum current consumption restriction I of allowance
maxif limit principal current circuit breaker higher than this and should trip.In measured electric current I, do not surpass the maximum current consumption restriction I permitting
maxsituation under, can according to before in step 302 definite allowance charging current level proceed charging process and control and turn to step 304.As long as measured electric current I remains on the maximum current consumption restriction I of allowance
maxbelow, step 304 to 306 can be continue or periodically implement.
If determine that in step 306 measured electric current I is greater than the maximum current consumption restriction I of allowance
maxcontroller circuitry 292(its be a part for charge point 21 or Service Circuit plate 24 or be distributed between the two) analyze being connected to the electric current supply of all electrical equipment of electric power system, and be operating as simulation for the current-time characteristic of tie breaker/introducing power circuit of main circuit board, thereby the maximum current being consumed by charge point under the situation prerequisite not breaking with enough confidence level predictions.More specifically, whether the current value identification of controller based on measured there is the special time restriction that allows charging process to proceed under the prerequisite that does not change charging current, whether charging process should stop, or proceeds to avoid to stop charging process with the charging current reducing.For example,, when determining that in step 306 measured electric current I is greater than the maximum current consumption restriction I of allowance
maxtime, the analysis of the electric current I of controller based on to measured, select in the following step:
If determine that the level of measured electric current I allows to proceed charging process in the current-time characteristic of time circuit breaker, in step 306b, controller is determined a time restricted T, and this time restriction T has defined and can not change the period of proceeding charging process under the prerequisite that charging current and main circuit breaker do not trip;
Although if determine that measured electric current I has reached the maximum current consumption restriction I that is obviously greater than allowance
maxlevel, but match by charging current being adjusted into the current-time characteristic of tie breaker, charging process still can be proceeded, in step 306a, correspondingly reduce the charging current of permitting, and correspondingly indicate the controller of charge point and/or vehicle to regulate the charging current of drawing from electrical network; And
If measured electric current I reaches the high level to proceeding charging process under the prerequisite that cannot not trip at main circuit breaker, in step 306c, controller stops charging process to prevent main circuit breaker tripping operation, and after this in step 306d, (for example, by sending, can listen and/or indication as seen, and/or by showing text message and/or corresponding image in the display unit at charge point or vehicle, and/or send this text/image by wired or wireless communication) correspondingly notify user.
In step 306a or the effective situation of 306b, this process can proceed to step 308, in step 308, consumed total current I is measured, to check in step 309 whether the electric current consuming is still greater than the maximum current I of allowance
max.If determine that wastage in bulk or weight electric current is not more than permitted maximum electric current, control and get back to step 310 to 303, to determine new allowance charging current.
If determine that in step 309 wastage in bulk or weight electric current is greater than permitted maximum electric current, whether in step 310, check under the prerequisite that should adjust to allow charging process not trip at main circuit breaker to time restriction (T) or charging current (Ig) and proceed.If determine and need to adjust time restriction and/or charging current is proceeded charging process, the level of controlling according to measured electric current mentioned above is delivered to step 306a, 306b or 306c.
If definite charging process can be proceeded under the prerequisite that does not regulate time restriction and/or charging current, control and forward step 311 to, wherein whether review time restricted T exhausts.If determining charging process in step 311 (can proceed, t<T), control and proceed to step 308 with current measurement and the levels of current inspection of repeating step 309 and 310, otherwise control and forward step 301 to 303 to determine new allowance charging current, as described above from step 311.
