Genom att tillhandahålla en anordning för strömstyrning för en laddningsstation med en prioriterad last och ett flertal uttag innefattar anordningen för strömstyrning medel för strömmätning för att mäta en prioriterad lastström, styrmedel för att styra de flertalet uttagen och en nödbrytare, varvid styrrnedlet är anpassat att styra en ström belastande de flertalet uttagen i beroende av den prioriterade lastströmmen, sporadiska höga laster kan hanteras vid en laddningsstation medan drift av en prioriterad last samtidigt upprätthålls.By providing a current control device for a charging station with a priority load and a number of sockets, the current control device comprises current measuring means for measuring a priority load current, control means for controlling the number of sockets and an emergency switch, the control means being adapted to control a current loading the number of outlets in dependence on the priority load current, sporadic high loads can be handled at a charging station while the operation of a priority load is maintained at the same time.
Företrädesvis är, för varje separat fas i ett trefassystem, den totala tillåtna strömmen för de flertalet uttagen lika med en märkström på en huvudsäkring för en huvudlastström minus aktuell ström i den prioriterade lasten. Altemativt är, för varje separat fas i ett trefassystem, total tillåten ström för de flertalet uttagen lika med en märkström på en huvudsäkring för en huvudlastström minus aktuell ström i den prioriterade lasten plus tillåten momentan överström för huvudsäkringen.Preferably, for each separate phase in a three-phase system, the total allowable current for the number of outlets is equal to a rated current on a main fuse for a main load current minus the current current in the priority load. Alternatively, for each separate phase in a three-phase system, the total allowable current for the number of outlets is equal to a rated current on a main fuse for a main load current minus the current in the priority load plus the permissible instantaneous overcurrent for the main fuse.
Företrädesvis fastställs den totala tillåtna strömmen separat för varje uttag.Preferably, the total allowable current is determined separately for each outlet.
Nödbrytaren är företrädesvis anordnad att bryta alla uttag fiån en huvudlastström när en separat fas i ett trefassystem överbelastas.

DETALJERAD BEKRIVNING Av FÖREDRAGNA UTFÖRINGSFORMER I följande beskrivning, i syfte enbart för förklaring och ej begränsning, beskrivs specifika detaljer, såsom särskilda tekniker och användningsområden i syfte att tillhandahålla en grundlig förståelse av föreliggande uppfinning. Emellertid kommer det att förstås för en fackman inom området att den föreliggande uppfinningen kan praktiseras med andra utföringsforrner än dessa specifika detaljer.DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS In the following description, for the purpose of explanation only and not limitation, specific details are described, such as particular techniques and uses, in order to provide a thorough understanding of the present invention. However, it will be understood by one skilled in the art that the present invention may be practiced with other embodiments than these specific details.
Till exempel är detaljerad beskrivning av välkända metoder och apparater utelämnade för att inte förvirra beskrivningen av den föreliggande uppfinningen med onödiga detaljer.For example, detailed descriptions of well-known methods and apparatus are omitted so as not to confuse the description of the present invention with unnecessary details.
En anordning för strömstyrning för en laddningsstation enligt föreliggande uppfinning kommer nu att beskrivas med referens till figur 1-2.A current control device for a charging station according to the present invention will now be described with reference to Figures 1-2.
Laddníngsstationen innefattar en huvudsäkring l, en prioriterad last 4, ett flertal uttag 5-8 och anordningen för strömstyming. Anordningen för strömstyming inkluderar medel för strömrnätning 2 och en nödbrytare 3. Laddningsstationen är t.ex. en parkeringsyta utanför en galleria där gallerian är den prioriterade lasten.The charging station comprises a main fuse 1, a priority load 4, a number of sockets 5-8 and the device for current control. The device for current control includes means for current mains 2 and an emergency switch 3. The charging station is e.g. a parking space outside a mall where the mall is the priority load.
Anordningen för strömstyrning är anordnad att mäta en prioriterad lastström flytande från den prioriterade lasten 4, vilken prioriterad lastström åtminstone delvis belastar huvudsäkringen l med 3 strömförsörjning till en användarinstallation. Strömmen mäts på ett lämpligt konventionellt sätt.The current control device is arranged to measure a priority load current fl surface from the priority load 4, which priority load current at least partially loads the main fuse 1 with 3 power supply to a user installation. The current is measured in a suitable conventional manner.
Strömmen flytande genom huvudsäkiingen 1 är beroende av belastningen från den prioriterade lasten 4 och lasten från de flertalet uttagen 5-8.The current fl flowing through the main fuse 1 depends on the load from the priority load 4 and the load from the fl number taken 5-8.
Nödbrytaren 3 är t. ex. implementerad genom en reläbrytare.The emergency switch 3 is e.g. implemented by a relay switch.
Varje uttag 5-8 innefattar en av följande anordningar: ett styrbart trefas laddningssuttag; ett styrbart trefasuttag; ett icke-styrbart trefas laddningsuttag; ett icke-styrbart trefasuttag; ett styrbart enfas laddningsuttag; ett styrbart enfasuttag; ett icke-styrbart enfas laddningsuttag; ett icke-styrbart enfasuttag.Each terminal 5-8 includes one of the following devices: a controllable three-phase charging terminal; a controllable three-phase socket; a non-controllable three-phase charging socket; a non-controllable three-phase socket; a controllable single-phase charging socket; a controllable single-phase socket; a non-controllable single-phase charging socket; a non-controllable single-phase socket.
Under drift visar anordningen för strömstyrning 9 strömmen flytande till den prioriterade lasten 4.During operation, the current control device 9 shows the current flowing to the priority load 4.
Anordningen för strömstyrning distribuerar sedan strömkonsumtionsrättigheter till uttagen lika med skillnaden mellan märkström på huvudsäkringen l och den aktuella strömmen flytande till den prioriterade lasten 4. Alternativt är temporär överbelastning av märkströmmen på huvudsäkringen l distribuerad, med hänsyn tagen till förväntade egenskaper för säkringen. Anordningen för strömstyrning visar sedan strömmen flytande till uttagen för att tillförsäkra att strömkonsumtionsrättighetema inte överskrids. Om strömmen flytande till uttagen överstiger strömkonsumtionsrättighetema är nödbrytaren anmanad att bryta strömmen till de flertalet uttagen.The current control device then distributes current consumption rights to the outlets equal to the difference between the rated current on the main fuse 1 and the current current fl surface to the priority load 4. Alternatively, temporary overload of the rated current on the main fuse 1 is distributed, taking into account expected characteristics of the fuse. The current control device then shows the current fl surface to the sockets to ensure that the power consumption rights are not exceeded. If the current output to the sockets exceeds the power consumption rights, the circuit breaker is prompted to cut off the power to the number of sockets.
Vidare, om ett uttag inte konsumerar sin tilldelade ström utförs omdistribuering av den rättigheten. Återställning av nödbrytaren utförs företrädesvis när tillgänglig ström är tillräcklig för förväntad belastning av åtminstone ett styrbart uttag.Furthermore, if an outlet does not consume its allocated power, redistribution of that right is performed. Reset of the emergency switch is preferably performed when the available current is sufficient for the expected load of at least one controllable socket.
Med uttrycket laddningsuttag menas en anslutning anpassad för att ladda en PHEV. Med uttrycket uttag menas en reguljär anslutning t.ex. för anslutning av en värmare eller andra fordonsmonterade strömkonsumenter såsom kupékylning. En typisk elektrisk motorvärmare med en kupéfläkt ansluts till en enda fas och konsumerar omkring 2 kW motsvarande approximativt 10 A. En typisk PHEV är ansluten till en enda fas och konsumerar styrbart mellan 2-3 kW, motsvarande 10-14 A. En föreslagen framtida snabbladdningsstandard för elektriska fordon är ansluten till tre faser och konsumerar styrbart upp till 43 kW, motsvarande 63 A. Dagens högsta märkning av slutsäkring för ett 400 V system i Sverige är 216 A.The term charging socket means a connection adapted to charge a PHEV. The term socket means a regular connection e.g. for connecting a heater or other vehicle-mounted power consumers such as passenger compartment cooling. A typical electric motor heater with a coupe fl genuine is connected to a single phase and consumes about 2 kW corresponding to approximately 10 A. A typical PHEV is connected to a single phase and consumes controllably between 2-3 kW, corresponding to 10-14 A. A proposed future fast charging standard for electric vehicles is connected to three phases and consumes controllably up to 43 kW, corresponding to 63 A. Today's highest marking of final fuse for a 400 V system in Sweden is 216 A.
Under en variant av drift av anordningen för strömstyrning visas huvudlastströmmen flytande 4 genom huvudsäkringen. När den totala lasten på laddningsstationen drar en ström lika med eller över märkströmmen för huvudsäkringen, och de flertalet uttagen innefattar en styrbar last, är en eller flera av dessa styrbara laster anmanade att reducera sin respektive last. När de flertalet uttagen inte innefattar en styrbar last, eller när den möjliga reduktionen av last inte är tillräcklig för att reducera huvudströmmen under märkströmmen, anmanas nödbrytaren att bryta strömmen till de flertalet uttagen. En andra utföringsform av föreliggande uppfinning visas i Fig. 3, vilken är identisk med den första utföringsformen av föreliggande uppfinning beskriven ovan förutom att nödbrytaren är innefattad inom anordningen för strömkontroll 2, och även att figuren visar de tre faserna av kraftnätet separat från varandra, för fasledare la, lb och lc, respektive.During a variant of operation of the device for current control, the main load current visas surface 4 is shown through the main fuse. When the total load at the charging station draws a current equal to or above the rated current of the main fuse, and the number of sockets includes a controllable load, one or more of these controllable loads are prompted to reduce their respective loads. When the number of sockets does not include a controllable load, or when the possible reduction of load is not sufficient to reduce the main current below the rated current, the emergency switch is prompted to cut off the power to the number of sockets. A second embodiment of the present invention is shown in Fig. 3, which is identical to the first embodiment of the present invention described above except that the emergency switch is included within the device for current control 2, and also that the clock shows the three phases of the power grid separately from each other, for phase conductors 1a, 1b and 1c, respectively.

Företrädesvis frånkopplar nödbrytaren alla tre faserna samtidigt. Emellertid, t.ex. när endast enfasuttag används i en laddningsstation frånkopplar nödbrytaren endast en enda fas vid överlast. Återställning av nödbrytaren sker på ett motsvarande sätt.Preferably, the emergency switch disconnects all three phases simultaneously. However, e.g. when only single-phase sockets are used in a charging station, the emergency switch disconnects only a single phase in case of overload. The emergency switch is reset in a corresponding manner.
