 Mayor wants LA to be #1 city for EVs  EVSE can influence adoption rates  Where will public investment in EVSEs generate highest benefit?

 EVs require a completely new infrastructure to connect to electricity grid  Single-family residential: not an issue

 Focus on Problem Areas:  Multi-family residential  Employment Centers  Commercial Centers

 Goal:  Anticipate concentrations of EV ownership  Use 2008 Hybrid ownership data as proxy for EV ownership  Origins: Multifamily residential problem  Destinations: Making sure they can charge at destination

 Absolute number of vehicles?  Percent capture of total vehicles in LA?  Percent of total vehicles within zip code?

Zip Code 90501: #1 for vehicles: 2,537 #8 In terms of Percent of Local Zip Code Zip Code 90001: #2 for Penetration of Local Zip Code Only has 2 vehicles! What’s the best measurement?

 41,079 hybrids in LA  12,948 in the top 10 (32%)

 In top 10, what is percent housing type?  Data Problem: don’t know housing type by hybrid vehicle ownership.  Assumption: Hybrid owners reflect zip code housing type distribution

 90071: no housing, but ranks 5 th (1,070) by total hybrids – must be government/business/etc.  Multifamily charging is an issue:  Mix of SFR and MFR  Range 15% to 73%  Mean: 41%

 Index that combines vehicle ownership and multifamily housing  Greater weight on more vehicles (1-4)  Greater weight on more MFR (1-4)  Combine to create Investment Prioritization Index Hotspot Analysis  Index=[vehicles_weighted]+[MFR_weighted]

 Data Problem: don’t know exactly where hybrid owners commute  Assumption: use zip code trip distribution  Methodology:  Weight % allocation of trips by actual number of hybrid vehicles in origin zip codes  Aggregate for a complete picture of destinations

 Is destination charging a real concern?  Average Commute range: 40 miles (r/t)  Battery Range: Miles  Not a real concern given current travel behavior, but people might travel differently with EVs

 Use Index to Allocate Funds to Origin Zip Codes that will benefit the most.  Know the top 10 destinations for these origins.  Not imperative to invest in public charging given vehicle range  Need to monitor/track travel behavior  Providing EVSEs at these stations could induce greater adoption (but is it best use of public funds?
