ELECTRIC VEHICLE CHARGING OPTIONS Local Retail Arteries/ Corridor Destinations Workplace Fleet Residential 10 10
ELECTRIC VEHICLE CHARGING OPTIONS Public Fueling Return-to-base Type Level-1 Level-2 Level-1 Level-2 Power 120V, up to 1.9kW @ (12-16 amp) 240V, up to 19.2 kw (80 amp) 200-500V, up to 40 kw (80 amp) 200-500V, up to 100kW (200 amp) Charge Time (Miles of range per hour of charge) 3 to 5 miles 3.3 kw 10 to 14 miles 6.6 kw 20 to 25 miles 9.6 kw 40 to 45 miles 19.2 kw up to 60 miles 40 kw up to 120 miles 100 kw up to 300 miles Cost and complexity tends to increase the faster the charging level. Did you know? Most plug-in electric vehicles can be charged on a household outlet overnight. Vehicles can be charged in a number of ways; characterized by the speed of charge. Selection should be based on site characteristics and the typical needs of users 11 11
ELECTRIC VEHICLE MYTHS MYTH: Plug-in electric vehicles can only support short trips, not daily commutes. FACT: The average is 40 miles or less, and most full battery electric vehicles are targeting close to 100-mile range on a full charge, and with plug-in hybrid electric vehicles, you can go even further up to 300 miles or more. MYTH: Plug-in electric vehicles aren t clean. Instead of burning gas, they run off of dirty power plants. FACT: Even when emissions from power plants are taken into consideration, electric vehicles contribute significantly less green house gases than traditional cars. MYTH: Electric vehicles will make your energy bill go way up. MYTH: Electric vehicles are far more expensive than the average car. 12 FACT: Slightly higher electric bills are offset by savings at the gas pump. This would be like filling up for a few cents per mile, compared to the average 14 cents for a traditional car. FACT: Federal tax incentives are available, up to $7,500 as well as possible state and local incentives. Compared to gaspowered cars, you will save on fuel, maintenance and repair costs. 12
NATURAL GAS REFUELING MODELS Fueling station type Characteristics Station development cost Number of U.S. Stations Examples Build CNG refueling Developed by private and municipal fleets Many open to the public or other fleets $500 thousand to $2 million ~750 Waste Management City of Denver UPS Xcel Energy Build new dedicated-cng stations Developed by utilities and specialist alternative-fuel companies Typically fleet anchor customers, many open to the public $1.5million to $2 million ~475 Clean Energy Sparq CNG Ward Alternative Fuels Gain Clean Fuels Trillium Add CNG capacity to existing station Developed by small or regional petroleum retail chains Public stations with fleet anchor customers (or their own fleet refueling) $500 thousand to $1.5 million ~75 Kwik Trip Love s 13 A Realistic View of CNG Vehicles in the U.S :https://www.bcgperspectives.com/content/articles/energy_environment_automotive_realistic_view_cng_vehicles_us/ 13
