2 Charging – What Can Be More Simple? G. Kissel8/10/09Charging – What Can Be More Simple?
3 PEV Charging – Consistent and Familiar G. Kissel8/10/09PEV Charging – Consistent and FamiliarMinimize charging equipmentResidential slow charge rate – portable cord setsResidential and public intermediate charge rate – fixed charge equipmentPublic fast charge rate – fixed charge equipmentCommonize the user charging experienceGasoline pump analogy – Each pump may have multiple grades of gasoline available but fueling is the sameReduces customer apprehension and speeds acceptance of the technology120VCordset
4 Charging Infrastructure Philosophy B. Gross, Plug-in 20098/11/09Charging Infrastructure PhilosophyPublic chargingHigh VisibilityCommercial/RetailWorkplaceCorporate, Municipal Parking LotsResidential (majority)Satisfying consumer-driven home installation processIncludes single and multiple family homes, apartments and remote charge locationsPermits, electricians, inspections, meters, ratesPublicWorkplaceResidential
5 Terminology AC Level 1 Charging* AC Level 2 Charging* G. Kissel8/10/09TerminologyAC Level 1 Charging*120V AC charging from standard 15 or 20 amp NEMA outlet, on-board vehicle charger (~1.9kw)AC Level 2 Charging*208 – 240 AC charging up to 80 amps, on-board vehicle charger (~19kw)DC Charging (Fast Charging)**Off-board charger connects directly to vehicle high voltage battery busCharger controlled by vehicle which allows for extremely high power transfer (~80kw) and thus faster recharge times (minutes instead of hours)Actual charge rate limited by battery chemistry, infrastructure and other factors* Same charge coupler used for AC Level 1 and 2 charging** Requires unique charge coupler other than the AC Level 1 and 2 coupler. Currently under development.
6 Terminology Electric Vehicle Supply Equipment (EVSE) G. Kissel8/10/09TerminologyElectric Vehicle Supply Equipment (EVSE)General term used for any off-board equipment used to supply charge energy to the vehicle. EVSE includes:CordsetsCharge Stands (public or residential)Attachment PlugsPower OutletsVehicle ConnectorMiscellaneous Infrastructure
7 Components of PEV Charging System – Vehicle Inlet/Plug G. Kissel8/10/09Components of PEV Charging System – Vehicle Inlet/Plug2 power contacts – up to 80 amps, 240V AC, 19.2kw1 ground contactControl Pilot signalVerification of vehicle connectionSupply equipment ready to supply energyPEV ready to accept energyVentilation requirementsSupply equipment current capacityEquipment ground presentProximity detectionIndicates to vehicle that plug is present to prevent drive awayLatch feature
8 G. Kissel8/10/09Components of PEV Charging System – Electric Vehicle Supply Equipment (EVSE)Can be a 120V cord set or 240V fixed mountedIncludes enclosure and method of attachment to AC mains (plug or direct connect)Generates Control Pilot signalProtects from ground faultsSwitches power to vehicle based on vehicle commandDisplays presence of AC input power240V Charge Station
9 Components of PEV Charging System – On-Board Charging System G. Kissel8/10/09Components of PEV Charging System – On-Board Charging SystemControl systemInterprets Control Pilot and proximity signal informationCharge algorithmOn-board chargerConverts AC mains power to DC high voltage to charge PEV batteryConverts AC mains power to DC low voltage to power vehicle system during chargeThermal systemCondition PEV batteryCool chargerCharge status indicatorVolt
10 PEV Charging – How It Works G. Kissel8/10/09PEV Charging – How It WorksCharge plug not powered until plugged into and commanded by vehicleSupply equipment signals presence of AC input powerVehicle detects plug via proximity circuit (prevents drive away while connected)
11 PEV Charging – How It Works G. Kissel8/10/09PEV Charging – How It WorksControl Pilot functions beginSupply equipment detects PEVSupply equipment indicates to PEV readiness to supply energyPEV ventilation requirements are determinedSupply equipment current capacity provided to PEVPEV commands energy flowPEV and supply equipment continuously monitor continuity of safety groundCharge continues as determined by PEVCharge may be interrupted by disconnecting the plug from the vehicle
12 PEV Charging – Safety & Durability G. Kissel8/10/09PEV Charging – Safety & DurabilityReceptacle and plugSpecified to comply with international standards including:J1772™IEC 62196UL 2251Electrical safety10,000 cycle life with exposure to dust, salt and waterVehicle drive over does not expose a hazardSealingCorrosion resistanceTouch temperature limits

14 Implementing the standard Vehicles Launching This YearImplementing the standard
22 J. Ewanick - Plug-in 2010 Conference 7/27/2010PI07With this mobile app, people can use their phones to remotely check the vehicle’s current state of charge, remaining range, and even pre-condition the cabin temperature of the Volt before you get into the car on a cold Midwestern morning.The app can be used to receive text messages from the vehicle on charge status and charge interruptions. So before you leave work you might get one text from your spouse saying to stop and get milk, and one from the Volt saying… hey, don’t forget to plug me in when you get home.The app will also perform remote start, and remote door lock or unlock and remote horn and lights. Other traditional OnStar features like automatic crash response, stolen vehicle assistance and/or slowdown, turn-by-turn navigation and hands-free calling are all included, standard, in the five-year package.
