EPRI Workplace Charging Policy and Strategy
• Facilities are a mix of research
and practical use
– Our installations were relatively
expensive due to this (we
received no incentives)
• Mix of company and personally-
owned vehicles
• Employee and official guest
charging is free—due in part to
legal requirements
– Employees must charge at
home if available
– EPRI vehicles have priority

Planning and Implementing Infrastructure
• Understand workable models
• Public vs. private ownership
• Plan for scale of PEV adoption
• DC fast charging
• Need (some) infrastructure everywhere
• Voluntary pre-notification
• Satisfying consumer-driven
home installation process
• Permits, electricians,
inspections, meters, rates
• Smart charging easy and available
• Employer education and outreach
• Best practices
• Low cost installations

Workplace Charging – EPRI ‘Red-Line Blue-Line’
Level 1 vs. Level 2: PHEV40 at the Workplace
Charging at a 1.44 kW results in higher charger utilization for BEVs…
Overall need is still low.
Level 1 – 1.44 kW Level 2 – 6.6 kW

Workplace Charging – EPRI ‘Red-Line Blue-Line’
Level 1 vs. Level 2: BEV100 at the Workplace

Workplace Charging Electricity Demand
EPRI Palo Alto Campus at 100% Utilization
• Workplace charging peaks in early morning, done by noon.
• Company or fleet vehicles benefit from Level 2
• Employees need only very low power in most situations
• Facility cost driven by getting power out to the site

– Our installations were relatively

• Employee and official guest

– EPRI vehicles have priority
Some of Our Guiding Principles
• Level 1 works for almost
everyone (or charger sharing)
• Demand for charging spots is
growing rapidly—plan for the
future
• Collecting money is generally not
worth the effort
• Focus on inexpensive, robust,
and reliable equipment
• Employee charging demand
currently driven by desire—not
need
• The ‘honor’ system works for us

Closing Thoughts
• We believe the workplace charging helps drive adoption:
Can you reasonably expect a given installation of
workplace charging to be close to fully utilized within a
year?
• What is the future of workplace charging—when does it
change from employee and public benefit to a practical
resource that must be managed?
When do we transition from the EPRI ‘Blue Line’ to the
‘Red Line’?

17. Case Study #2
http://www.youtube.com/watch?v=WalQRscLU6g
 Each employee offered a monthly $250 allowance to
lease or buy any vehicle that qualifies them to get a
California carpool lane sticker.
Faster commute = more work productivity
 If they get the Nissan LEAF their allowance completely
covers the cost of the lease.
Evernote negotiated a special deal with Nissan.
 10 Level 2 charging stations and one DC fast charger

18. Discussion
Existing and Emerging Policies
• What incentives exist for employers to install PEV charging
infrastructure?
• Rule 2202 – SCAQMD (example)
• Examples from state incentives to share?
• Tax benefits / credits
• Resale of electricity
• HOV lane exemption
• Vehicle rebates
• Utility rebates
• Find out what incentives are available where you live:
• http://goelectricdrive.com/index.php/incentives
• Does your company offer any incentives to employees to adopt
PEV’s? Financial incentives?
• Polices you aware of that support adoption of PEV for employees?
