Why put in charging?

• Attract progressive, forward thinking,
  intelligent, affluent customers to you
• Demonstrate that you are a forward thinking
  establishment that is concerned about the future
  of the US and mankind
• Help your customers/employees maintain their own
  sustainable lifestyle
• Help push for a sustainable future

3
What can I do today?

• Run wires to some parking spaces
• Reserve a parking space
• Have wires available for future upgrade
• Provide chargers
• Provide outlets

4
Charger Types

• Chargers and Charging Connectors
• Incompatible types of connectors
• Old Style Inductive and Conductive
• Not good for any future vehicles
• About 500 vehicles left built 1997 - 1999
• SAE J1772 - standard still in development.
  Hardware is not available today. 2010? 2011?
• All future EVs after finished should use this.
• Tesla
• Similar to J1772. Will be upgradeable to J1772
• 2000 Tesla Roadsters by end of 09, 5000 by end
  of 10
• BMW Mini-E 500 vehicles in NJ and CA
• eBox 12 vehicles, mostly in CA

5
Vehicle Types

• NEV - Neighborhood Electric Vehicle
• Limited to 25 mph on 35 mph roads
• Goes 20 - 30 miles on a charge
• PHEV - Plug-in Hybrid Electric Vehicle
• Can run off of Gasoline or Electricity
• Extreme fuel efficiency when running off of
  Electricity
• Can us Gasoline when battery runs out after 7 -
  40 miles
• EV - Electric Vehicle
• Runs purely on electricity
• Goes 90 - 200 miles on a charge
• HEV - Hybrid Electric Vehicle
• Runs entirely on gasoline
• Uses electric motor to increase efficiency
• What about Hydrogen?
• Special refueling required - millions

6
How much can I make?

• Electricity Costs
• Daily Commuter with EV or PHEV
• 30 miles/day
• Electricity 35/month Gas 80/month
• NEV driver
• 10 miles/day
• 7/month
• Highway Drivers
• 100 miles per fillup
• 2.50 per fillup Gas 8 per 100 mi fillup
• Most fillups will be at home. Will use
  infrequently.
• Market Pricing
• What is it worth to them?
• What are they worth to me if this brings them in?

7
How do I charge

• Meter the electricity ( per Kilowatt-hour)
• PUC regulations can make this difficult for
  anyone except electric company
• Charge per time charging or parked
• /minute varies with Wattage provided
• May encourage customers to leave early
• Businesses can adjust charging rate to how long
  they want customers to linger (restaurants will
  probably want fast charging, malls want slower)
• Flat Rate Monthly service
• Good for apartment or residential parking lots
• Will not attract EV driving homeowners

PIA Recommended Minimal Plug-in Spot

• Electrical box mounted between 2 parking spots
• 1 spot reserved for EV charging
• Single spot initially until demand increases
• Marked No Parking, violators will be towed -
  Electric Vehicles charging excepted
• Can be Handicapped, EVs excepted if desired
• 2nd spot not reserved until demand reached
• Dual NEMA 5-15 or 5-20 connector on Post
• Safety Bollards (Post) mounted in front of
  electrical box to protect charger post
• All circuits should have GFCI protection
• Best for retrofits as new construction can be
  wired for higher power at minimal additional cost
• Put in as many of these as you feel you can

Experience Has Shown

• Reserved parking spaces for EV charging tend to
  elicit jealousy from Internal Combustion Engine
  (ICE) vehicle drivers, especially when parking
  spaces are in short supply and even more, when
  the EV spaces are in prime positions. Polite EV
  drivers only want the charge, not the prime
  spaces, therefore, they would prefer to have EV
  spaces in less desireable areas such as the back
  of parking lots, not near store entrances or
  other prime locations.
• There are and likely could be multiple types of
  chargers. It is probably desirable to put more
  than 1 type in each place to accommodate
  different types of EVs.
• Single charging post can supply 2 - 4 parking
  spaces with the same installation costs
• For high capacity location with many charging
  sites, it may be cheaper and more efficient to
  bring large 3-phase, high voltage 440V cable to
  transformer that is close to charging sites. An
  electrician can determine if this is best
  approach.
