  1. Source: Ecotality David Peterson UP206a – GIS (Estrada) December 6, 2010 Locating Electric vehicle charging stations in Los angeles

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

  3. EVs require a completely new infrastructure to connect to electricity grid Single-family residential: not an issue Problem statement

  4. Focus on Problem Areas: • Multi-family residential • Employment Centers • Commercial Centers Problem statement

  5. 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 Methodology

  6. Absolute number of vehicles? Percent capture of total vehicles in LA? Percent of total vehicles within zip code? Origins: measuring hybrid ownership

  7. 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?

  8. 41,079 hybrids in LA 12,948 in the top 10 (32%) Top 10 LA Zip codes: hybrid ownership

  9. 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 Origin: multifamily housing problem

  10. Origin: multifamily housing problem

  11. 90071: no housing, but ranks 5th (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% Origin: multifamily housing problem

  12. 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] Origins: prioritizing investment

  13. Origins: prioritizing investment

  14. 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 Destinations: hybrid commutes

  15. Is destination charging a real concern? Average Commute range: 40 miles (r/t) Battery Range: 80-100 Miles Not a real concern given current travel behavior, but people might travel differently with EVs Destinations: hybrid commutes

  16. 90501 destination trip example

  17. 90501 destination trip example

  18. Destinations: hybrid commutes

  19. Destinations: hybrid commutes

  20. 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? Conclusion
