Volt IS an...
Extended-Range Electric Vehicle
without range anxiety
• The Volt operates on battery power alone up to 40 miles
without using gas or producing emissions
• It uses electricity to move the wheels at all times
and speeds
• The engine generator provides electricity to power the
drive unit for extended-range capability
• It plugs into a standard household 120V outlet or 240V for
charging
High-tech aesthetic... Warm and inviting
• Driver-configurable instrument display/cluster
• 7-inch touch screen
navigation/vehicle
information display
• Touch-sensitive climate
and infotainment controls
• Optional navigation system with an onboard hard
drive for maps and music storage
• Standard Bluetooth for cellular phone and USB /
Bluetooth for music streaming

Charging and Infrastructure
Charging Power Level
• 3.3 kW/240V charging will usually require a one time investment
to upgrade the garage with a dedicated 240V circuit
• Full charge is <3 hours – very acceptable
• Fast charging will have customer value
• 1.2 kW/120V charging may work depending on the customer’s
situation
• Full charge in minimum 8 hours (temperature dependent)
• May require understanding and control of other devices on the circuit
• Charger and control logic is on-board
the vehicle
• Designed for global voltages
• 120V charge cord comes with the
vehicle in NA
GM / EPRI / Utility Collaboration
GM/EPRI/Utility Collaboration for Electrical Infrastructure
• The Collaboration includes more than 40 Utilities in North America… many the
industry’s thought-leaders in electric transportation and grid interaction
Why collaboration is important?
