Overview and Intended use environment
Indrasmartrangecanbeclassiedas‘smart’electricvehiclechargingsolutionbecauseof
their 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designpedestal.
In its operating environment, the temperature must be between -20 and 50°C, with humidity
between10%to85%non-condensing.
Supply voltage should be 230V AC at 50Hz, rated up to 32Amps, to allow for maximum
chargingcapability.

Indra Smart Features
Boost
Fundamentalfunctionofthechargerthatenablestheusertochargethecarwhen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powercapacitytoaccommodatethechargeralwaysoperatingatfullcapacity.
It works by monitoring the amount of power the installation is using via an external CT 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, 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.
Tari Intelligence
This feature enables the customer to tell the charger what electricity costs them and when,
thenthechargerwillchargethecaratthecheapesttimes.
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).
(Form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,bepre-emptivexesforidentied
issues,orusedtorectifyfaultsiftheoccur.
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 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 four of the indents of BS 7671:2018
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electrode.Thesafestinstallationcongurationis,modeAwith
referenceelectrode.
•ModeAwithreferenceelectrode–(ComplianttoBS7671:2018,regulation722.411.4.1,

measuresthevoltagebetweenL,N&CPCbetween184v-257.6v(230v+/-12%)
What it means:
o Removestheriskofnuisancetrippingduetosupplyvoltageuctuations(e.g.voltage
spikes due to energy export to the grid),
o Compliant install on a 3-phase supply,
o Prevents potentially dangerous voltages from occurring on the car chassis under
any circumstances,
o 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
