Plug-In Electric Vehicle Collaborative
• Public/private organization - accelerating the
adoption of plug-in electric vehicles to meet
California’s economic, energy and environmental
goals
• More than 40 PEV stakeholders - automakers,
utilities, charging equipment/network providers,
government, research & education

The Growing PEV Market
Why Install Workplace Charging?
• Recruit and retain
employees
• Green your image
• Improved commute –
increased employee
productivity
• Help comply with local
air quality and
transportation policies
• LEED points toward
certification
Key Considerations
• Review key workplace charging resources
• Plan for growth
– Survey employees to determine current and
future interest in PEVs
• Establish internal procedures
– Level of access, payment options, etiquette
• Dedicate staff
– An employee is usually needed to manage the
chargers and employee use
• Contact local utility and landlord or
facilities manager to evaluate charging

Workplace Charging Overview
– Small amount in region - we’d like to increase it
– Other than home, EVs are parked longest at work
– Provides PHEV drivers a way to drive more electric miles
– Allows BEV drivers to commute longer distances successfully
– Benefits EV drivers that don’t have access to home charging

Equipment Selection – Level 1
• Level 1 (120v, usually at 1.4 kW)
– Typically adds 4-6 miles of range per hour
– Most cars come with AC Level 1 cord set
– Will run on standard 15 amp circuit
– Advantage: Can be used anywhere
– Disadvantage: Slower charging
– Grid Impact: Mild
Equipment Selection – Level 2
• Level 2
(208-240v at 3.7 kW, 7.2 kW, 9.6 kW, & 19.2 kW)
– Most 2011-2012 cars using Level 2 draw 3.7 kW
– Many newer models will draw 7.2 kW (2013+)
– Needs a dedicated 208-240v circuit
– Advantage: Faster Charging
– Disadvantage: Higher Cost
– Grid Impact: Moderate
Power Sources for EV Charging
• Existing Electric Panels:
– Usually cheapest solution
– Spare capacity is usually minimal
– Expensive to expand
– Minimal utility involvement
• New Electric Service:
– Forward thinking; location freedom
– Separate billing (3rd parties)
– More capacity
– Makes sense for large charging loads
Workplace Charging Questions:
• How many employee cars now?
• How many expected in future?
• How many charging stations are you thinking of?
• Is there a budget?
• Is available power nearby?

EV Charging Project Guidance:
– Typical EV Charging Project
• Consult with utility on electrical requirements
– New service, RFS Form
– Existing Panel
• RFP Process (if applicable)
• Hire engineering firm to design project
– Electrical / ADA requirements
• Hire contractor to build project
• Procure equipment & materials
• Get permits
• Construction takes place
• Approvals / Testing / Commission
• Misc. issues
– Parking Policies for employees
– Billing EV drivers
