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 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?

Impact on the Electric Grid
Electricity: An important energy source withsignificant capacity to support transportation
• 10 million E-REVs in 2010 would add a load that is less than 1% of the total grid load

Electric Grid Design for Peak Demand
• The last 5% of the system’s capacity is needed less than 1% of the time
• The last 25% of the system’s capacity is only needed about 10% of the time
• The real objective of smart charging is simply to avoid these peaks with most of the vehicles out there
• This has tremendous value for the utilities – and very achievable once the technology is in place to manage vehicle charging
For example, in California like most hot-weather states with a lot of air conditioning:
