 normaloperation.

7
Overview and Intended Use Environment
IndraSmartRangecanbeclassiedasa‘smart’electricvehiclechargingsolutionbecause
of the communications infrastructure which allows charging to be remotely optimised by
the Indra App; where charging can take place when electricity is cheapest; or if immediate
chargingisrequired,its‘Boost’functionalityoverridesanysmartgridcriteriaandprovides
instantaneouschargingcapability.
ChargingusingIndraSmartchargerscantakeplaceatupto7.4kW,butduetomodulation
capability(measuredbytheexternalCTclamp)thispoweroutputlevelcanalsobereduced.
The Smart Range are intended for both indoor and outdoor installation, securely mounted to
awallorappropriatelypedestal.
In its operating environment, the temperature must be between -20°C and 50°C, with
humiditybetween10%to85%non-condensing.
The supply to the charger should be 230V AC +10/-6%, 50HZ and rated >=32A for maximum
chargingcapacity.

Indra Smart Features
Boost
Fundamental function of the charger that enables the user to charge the car when the
chargerisoine,ortooverrideanysetschedules.Thisfunctionismostoftenusedwhenthe
userneedsthecarchargedearlierthannormal.
House Fuse Protection (Load Curtailment)
Is a function that allows an EV charger to be installed at a property that may not have
enoughsparecapacitytoaccommodatethechargeralwaysrunningatfullpower.
It works by monitoring the amount of power the installation is using via an external CT
clampandcomparingthattotheratingofthemaincut-outsupplyingtheinstallation.Ifthe
dierenceisgreaterthan32Athenthechargerwilloerfullcharge.Ifthedierenceisless
than32Athenthechargerwillonlyoerasmuchpowerasthereissparecapacityonthe
maincut-out.
Note:G100.2deneshowloadcurtailmentismanaged.Ifthechargerisconguredtouse
load curtailment and it loses contact with the external CT clamp, then the charger will
de-rateitspoweroutputto6Atoprotectthemaincut-out,thus6Aisthegurethatshould
beconsideredwhencarryingoutthemaximumdemandsurvey.
DC Leakage Protection
AnRDC-DDisttedintoIndraSmartchargers,oering6mADCleakageprotection.This
meanstheyshouldbeinstalledwithaTypeAortypeFRCDupstream.
O-PEN Fault Detection
IndraSmartRangehavebuilt-inO-PENprotectionintheformofIndra’spatentedPESTs.This
oersmultipleoptionstocomplywiththePENfaultregulations,includingLinetoNeutral
Voltagemonitoring(PESTmodeB)andCPCtotrueearthvoltagemonitoring(PESTmodeA).
(FormoreinformationseethePESTssection).

9
Over-The-Air Updates
TheSmartRangecanbeupdatedviaaninternetconnectiontothecharger.Theseupdates
canoerimprovementstothefunctionofthecharger,pre-emptivexesforidentied
issues,orcanbeusedtorectifyfaultsiftheyoccur.
Tari Intelligence
This feature enables the customer to tell the charger what electricity costs them and when,
thechargerwillchargethecaratthecheapesttimes.Thisfeatureisalsocompatiblewithall
timeofusetarisincludingagile.
Solar Mode
This mode can be selected in the Indra App and can enable the customer to use any excess
solarenergy(oranyotherformofmicro-generation)tochargetheircar.
TheexternalCTmonitorshowmuchenergyisbeingexportedfromtheinstallation.Ifthe
installationisexportingmorethan1.4KW,thenthechargerwilloerthecaracharge.
(1.4KWistheminimumamountofpowerrequiredforanin-carchargertoacceptacharge).
Note: The external CT clamp can only measure what energy is being exported back to the
grid, therefore, if the micro-generation is generating 2KW, and the installation is using 1KW,
thechargerwillonlydetecttheremaining1KWbeingexportedtothegrid.Thismeansthe
chargerwillnotoerachargetothecarbecausethereisn’tenoughpowertotriggerthe
in-carcharger(1.4KW).Exporttothegridneedstobe1.4kWorgreaterbeforethecarwill
beoeredcharge.
Smart Scheduling
Smart scheduling allows the user to create a schedule window - this is when the charger will
start and stop charging - but also, how many miles to add, how many kWh to add or how
muchmoney’sworthofenergytoaddtothecar.
Charge Analytics
TheIndraAppoerstheuserdetailedinformationaboutthebehaviouroftheirchargerand
their charging history, including how much money they have spent, how many miles have
beenaddedtothecarandoverallusage.

The Smart Range PESTs solution can operate under three of the indents of BS7671:2018
A1:2020+A2:2022;section722.411.4.1.Forthepurposesofdesign/installationwehavetwo
modesofoperationwhichIndracallA&B.ModeAcanbeconguredwithorwithouta
referencepin.ThesafestinstallationcongurationismodeAwithreferenceelectrode.
Mode A with reference pin – (Compliant to BS7671:2018, regulation 722.411.4.1, Indent
iii)
ThismethodmonitorsthevoltagedierencebetweenCircuitProtectiveConductor(CPC)
andtrueearth,disconnectingthecarfromthechargerintheeventofthevoltagedierence
risingabove30Vrms.ItalsomeasuresthevoltagebetweenL,N&CPCbetween184v-257.6v
(230v+/-12%).
What it means:
•  Removestheriskofnuisancetrippingduetosupplyvoltageuctuations(e.g.voltage
spikes due to energy export to the grid),
• Compliant install on a 3-phase supply,
• Prevents potentially dangerous voltages from occurring on the car chassis under
any circumstances,
• Removes simultaneous touch risks between the charger/connected car and conductive
 partsconnectedviaTT(e.g.lamppost).
Mode B – (Compliant to BS7671:2018, regulation 722.411.4.1, Indent iv)
Monitors the L-N voltage and will disconnect from the car if the voltage goes out of range
(253V-207V).ProtectedMultipleEarth(PME)isusedastheCPC,andnoearthrodor
referencepinisrequirediftherearenosimultaneouscontactortouchvoltageriskspresent.
Consideration should be given to nuisance trips where the line to neutral voltage may exceed
253V,especiallywherelocalrenewablesarepresent.
Mode A without reference electrode
Usedforinstallationsthatdonotfallundertherequirementsof722.411.4.1E.g.TT
