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

San Diego EV Stats: As of October 1, 2014 : – Over 11,000 electric vehicles on the road – Over 650 Level 2 commercial charging stations in service – 28 DC Fast Chargers in service 16

Plug-in Electric Vehicle Charging Home Single Family Residences Multi-unit Dwellings Workplace Public

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 ( v at 3.7 kW, 7.2 kW, 9.6 kW, & 19.2 kW) – Most cars using Level 2 draw 3.7 kW – Many newer models will draw 7.2 kW (2013+) – Needs a dedicated v 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 (3 rd 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 24
