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

3. 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

4. Industry Standardization New industry standards for charging of EVs are being developed

5. 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

7. 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

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

9. 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 domestically and doesn’t rely heavily on importing foreign oil
