= Need 300,000 workplace EVSE by 2017
210,000
350,000

8.  Fills a critical gap in PEV
Infrastructure needs
 Extends the range of PEVs
and builds the market
 Allows for more electric
only miles for PHEV’s
 Creates local ‘PEV
showrooms’ for info sharing
on vehicles
 EV’s can act as ‘employee
pool cars’ for day trips

15. Costs
» Hardware costs
» Level 1… just the cord to ~$1,000
» Level 2: $500 - $5,000
» DC Fast charging: $15,000
» Installation costs
» Can vary greatly depending on site conditions
» Few $100 to $5,000 per EVSE
» Operating costs
» Commercial el rates in US $ 0.8 -0.15/kWh
» Network costs – site host, monthly charge
$30/EVSE, membership for user
» Demand charges – can be avoided if managed, cost $10-
30/kW

Install System
Determine
recharging site(s)
Closer to existing electric utility
equipmentis cheaper, adding
new circuits and conduit can
increase capital costs
significantly
Review traffic, pedestrian
flow, parking requirements,and
ADA compliance issues
Consider such safety, proper
and sufficient lighting, potential
shelter from weather, general
personal/ property security, and
signage
Determineadditional retrofit
needs, including landscaping
Estimate electrical
load at site(s)
Determinewhether to use Level
1 or 2 charging or other
Obtain charger requirements
from vehicle and charger
suppliers
Determinethe appropriate
number of EVSE units
Consider expectations for
future expansion now, taking
into account the facility’s

21. Employee Policies Supportive of PEVs
» Cash incentives up to $4,000 for purchasing or
leasing a qualified PEV
» Company paid monthly lease – HOV access
» Free charging at work
21

22. Tax Questions
While no specific rules mention EV charging, these
rules are being used as guidelines
» Taxpayers can exclude from gross income any
fringe benefit that qualifies as a “de minimis”
fringe benefit (section 132(a)(4) of the Code). EV
charging not specifically identified
» Section 132 (f)(2)(B) of the Internal Revenue
Code, “Commuter Tax Benefits,” allows for a
fringe benefit exclusion for qualified parking. In
2013 this value was $245 per month.

23. Since PEV charging is not
explicit, related examples of
de minimus limits are:

Consult your tax
professionals for
official guidance.

24. Incentives
» Local and regional incentives – employee commute
reduction programs (large cities)
» 13 states have pending incentives for EVs
» HOV lanes
» Tax exemption or credits
» December 31, 2013, can deduct cost of the equipment
and installation, up to $30,000, under the Alternative
Fuel Vehicle Refueling Property Credit Act.

EV Chargers at Fox Studios
Currently have 20 Level 2 chargers
• 17 Blink and 3 Clipper Creek
• 4 in each parking structure, 3 on lot, 1 in transportation
• 40 - 50 users at present
Why Install EV Chargers?
Employee interest
• Hybrid & EV incentive program
• EVs in fleet

27. Dynamic Sealing Technology (MN)

• DGS funding for the purchase
and installation of 24 level II
Electric Vehicle (EV) Charging
stations. March 2012
• The EVSE stations have been
used 44 times a month
• Users aare monthly and public
parkers
• DGS plans on installing 9
additional EV charging stations
at the Fleet Garage located
1416 10th Street in Sacramento
to support the DGS electric
vehicle fleet.

Workplace Charging
 Website to share resources across regions and showcase
case studies www.evworkplace.org
 Understand Barriers to faster growth
 Identify process steps that are too costly and/or lengthy
 Identify successfully implemented programs – what
makes them special
 Workplace Charging – Best Practices Guideline with
