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
18
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?
22
Site Selection:
– Power Source
• New Electric Service• Existing Panel (Capacity)• Transformer proximity• Trenching• Existing Panel
– Parking
• ADA Requirements• “Making a Green Statement” by front door or choosing least cost• Balance power availability vs. parking convenience• Move Cords Not Cars• Reserving Spots• Striping and Signage
23
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

SDG&E Information
– Electric Rates
• Commercial “A” Rate• Commercial “AL-TOU” Rate• Residential “EV-TOU” Rate• Residential “EV-TOU2” Rate
– SDG&E Services for EV / Workplace Charging
• Site Visits (Clean Transportation)• Consultation (Clean Transportation)• Internal SDG&E Referrals (Clean Transportation)• New Service Assistance (Project Management)
SDG&E Workplace ChargingCase Study
– (Total) 51 Chargers at 15 locations
– (Century Park) 26 Chargers total
– 10 Chargers are on internal pilot program
• “Vehicle Grid Integration” or VGI program• Two Level 2 and Eight Level 1 units• Hourly Pricing: CAISO + retail adders + peak ckt loading adder• Charging sessions managed at kiosk or via web or phone app• Employees set kWh needed, max price, departure time• Managed charging benefits
