3. Local and external load management
Inlocalloadmanagementmode,severalWallboxes
arenetworkedviaanRS485bus.TheseWallboxes
sharetheavailabletotalcurrentequally.Anexternal
controlsystemisnotnecessaryinthiscase.Activating
thismodedoesnotrequiremakinganycommuni-
cationsettings.Pleaseobservetheinformationon
conguringandinstallingtheWallboxes.
Inexternalload/energymanagementmode,the
Wallboxesarenetworkedwithanexternalcontrol
system(e.g.HEMS–HomeEnergyManagement
System)viaanRS485bus.
Theexternalcontrolsystem(leader)managesthe
systemandcommunicateswithallconnected
Wallboxes(followers).Theexternalcontrolsystem
controlstheenergydistribution.Thisapproach
enablessolarenergytobefedinwhenanelectric
vehicleisbeingcharged,forexample.
1. Introduction
TheWallboxbasicEVOPROisusedtochargeplug-in
hybridorelectricvehicles.SeveralbasicEVOPRO
Wallboxunitscanbeoperatedinanintegrated
network.Thisenablesthepowerdistributiontobe
monitoredforupto16Wallboxes.Intheinterestof
simplicity,the‘WallboxbasicEVOPRO’willbeshort-
enedto‘Wallbox’below.Theintegratednetworkcan
beimplementedintheformoflocalorexternalload
management.
Fig. Vshowsanintegratednetworkcomprisingve
Wallboxesasanexample.Inanintegratednetwork
ofveWallboxes,theenergysupplyprovidesup
to32Aofcurrent.TheWallboxesarepre-setwith
Imax16AandImin6A.Thetotalchargingcurrent
(32A)isdistributedequally.Ifavehiclehasended
itschargingprocessbutremainsconnectedtothe
Wallbox,thisvehiclewillcontinuetobeprovided
with6Aofcontinuouscurrent(fortheauxiliary
heater,forexample),insomecasesalternatelywith
othervehicleswhichhavealreadybeencharged.
2. Installation of the bus system
Installationofthebussystemisdescribedbelow.
Thewiringisimplementedaslinewiring(see2.2)
orascentralwiring(see2.3).

theconductors,thepowersupply(2),the
chargingcable(3)andthebuslines(5).
• Securelyconnectthebuslinestothedesignated
screenconnections.
• Cutoffunusedindividualconductorsattheend
oftheinsulation.
2.2 Bus system in line wiring

Whenusinganexternalcontrolunit,terminate
thebuslinewitha120ohmresistor.Observethe
specicationsfromthemanufactureroftheexternal
controlsystemhere.
5. Bus protocol (external load
management)
TheModbusRTUprotocolisusedforcommuni-
cationbetweentheexternalcontrolsystemand
theWallboxes.EachWallboxisreadytoreceivea
Modbuscommandonlyaftermorethan10seconds
haveelapsedsincePowerOn.Ifthecorresponding
Wallboxisinstandbymode,itcannotbeaddressed
viaModbus.
5.1 Modbus connection
TheWallboxisconnectedtoanexternalcontrol
systemusingatwo-wireRS485bus(half-duplex).
Busparametersused:
• Baud19200bit/sec,

6. Checking load management
Puttheloadmanagementsystemintooperation
afterproperlyinstallingandconguringit.
i
Whencheckingtheloadmanagementsystem,
ensurethatnovehicleisconnectedtoanyWallbox.
• EstablishthepowersupplyfortheWallboxesin
localloadmanagementmode,beginningwith
theleaderWallbox.
• Establishthepowersupplyforalldevicesin
externalloadmanagementmode,beginning
withtheexternalcontrolelectronics.
• ThefrontilluminationofeachWallboxlightsup
for5minutesandthengoesout.
• Loadmanagementisnowreadyforoperation.
Diagnosisofcommunicationerrorsintheload

performedcorrectly.Oncethefaulthasbeen
remediedandaself-testhasbeenperformed,the
