  1. Charging at 120 and 240 Volts 120-Volt Portable Vehicle Charge Cord 240-Volt Home Charge Unit

  2. Charging at 120 and 240 Volts • Customers have options based on individual needs • 120-volt outlets are abundantly available • No additional equipment or installation required with 120-volt charging • 120-volt vehicle charge cord is portable • Charging at 240 volts is faster • Charging at 240 volts is efficient and enables more opportunity to drive electrically

  3. Industry Standardization New industry standards for charging ofEVs are being developed

  4. Industry Standardization • Society of Automotive Engineers J1772™ committee developing charging standards • SAE J1772™ committee made up of all major automakers, EV start-up companies and charging equipment suppliers • Vehicle charge cord plug and on-board charge receptacle have common functionality and design • New charging standards cover durability, safety and communication • Durability: Designed to be plugged in 10,000 times. Charge cord plug assembly designed to be driven over. • Safety: UL approval, drive away prevention, sealed connector, latching capability, ground fault monitoring and more • Communication: Electric Vehicle Supply Equipment (EVSE) to vehicle, available current, safety ground check and more

  6. Price: Gas vs. Electricity • Electricity price varies by state yet is still very inexpensive compared to gasoline • Charging during off-peak hours (evening/night) can be half the price of on-peak (daytime) charging • Cost per mile to drive electrically is a fraction of the cost compared to gasoline • Kilowatt Hours is the main unit of measurement vs. gallons of gasoline • Electricity rates are more stable than fluctuating fuel prices

  7. Electricity Generation – Diversity Among States Source: Energy Information Administration

  8. Electricity Generation – Diversity Among States • Electricity is generated in a number of ways and varies by state • Diversity of electricity generation is a function of what natural resources exist in a particular area • With grid management, the electric grid can handle millions of EVs • In many regions, “green” electricity made from renewable sources is becoming more available • Electricity is largely generated domesticallyand doesn’t rely heavily on importing foreign oil
