PEV Charging – Consistent and Familiar
Minimize charging equipment
Residential slow charge rate – portable cord sets
Residential and public intermediate charge rate – fixed charge equipment
Public fast charge rate – fixed charge equipment
Commonize the user charging experience
Gasoline pump analogy – Each pump may have multiple grades of gasoline available but fueling is the same
Reduces customer apprehension and speeds acceptance of the technology

5. Terminology AC Level 1 Charging* AC Level 2 Charging*
G. Kissel
8/10/09
Terminology
AC 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 bus
Charger 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. Kissel

Terminology
Electric Vehicle Supply Equipment (EVSE)
General term used for any off-board equipment used to supply charge energy to the vehicle. EVSE includes:
Cordsets
Charge Stands (public or residential)
Attachment Plugs
Power Outlets
Vehicle Connector
Miscellaneous Infrastructure

10. PEV Charging – How It Works
G. Kissel
8/10/09
PEV Charging – How It Works
Charge plug not powered until plugged into and commanded by vehicle
Supply equipment signals presence of AC input power
Vehicle detects plug via proximity circuit (prevents drive away while connected)

11. PEV Charging – How It Works
G. Kissel
8/10/09
PEV Charging – How It Works
Control Pilot functions begin
Supply equipment detects PEV
Supply equipment indicates to PEV readiness to supply energy
PEV ventilation requirements are determined
Supply equipment current capacity provided to PEV
PEV commands energy flow
PEV and supply equipment continuously monitor continuity of safety ground
Charge continues as determined by PEV
Charge may be interrupted by disconnecting the plug from the vehicle

With 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.
