8. Six Things We Need to Get Right • Market analysis • Technical features • Customer experience • Public education • Public policy • Advanced features and new opportunities

9. Charging Power Levels • 120V (1.2 kW) charging • Plugs into standard household outlet • Full charge in about eight hours (temperature dependent) • No additional equipment or installation (?) • Charge cord standard with the vehicle in NA • 240V (3.3 kW) charging • Full charge in about three hours • Efficient and enables more opportunity to drive electrically • Will usually require a one-time investment to upgrade garage with dedicated 240V circuit • Charger and control logic onboard the vehicle • Designed for global voltages 120V Cordset 240V ChargeStation

11. Home Charging can be a real satisfier for consumers, but there is a lot of potential variability that we have to help manage… • Garages can be filled with junk and need to be rearranged to make room for the charger • Some garages already have washers/ dryers or refrigerators that operate on 220V lines but making room for additional line a challenge • Locating charger on right or front of vehicle works better for some. But garage clutter is still an issue

15. Top Priorities for Overall Utility Support: • Consumer EV support (24/7 operator for EV charging questions) • Residential infrastructure assistance • Fast, convenient installation process that is affordable (i.e. satisfying) • Utility handles entire home installation process • OR • Coordination between Utility (meter) and 3rd party installer (EVSE) • Outreach and leadership in readying regions for plug-in vehicles • Key stakeholder outreach • City/regional initiative to put enablers in place • Consumer education • Compelling consumer EV rates and easy sign-up process • Inform customers of best options, preferred rates, green options • Policy assistance (e.g. eased permitting, building codes, incentives) • Expanded fleet purchases Home Inspection EVSE Installation Meter Installation Permit/Inspection Rate Signup

16. Plug-in Ready Communities Required Stakeholders • Dedicated project leader • State, city, county • Clean Cities Orgs/AQMD • DOT • Utilities (municipal and regional) • Regulators/public utility commissions • Permitting and code officials • Local employers • Local universities
