PEV Infrastructure in CA


• California leading state for deployment of and sale of plug-in vehicles

• California needs to be ready from an infrastructure perspective

• Many regional efforts in the state involving utilities, communities, cities, EVSE providers

• Communication and sharing between the different regional efforts is lacking

Background


CPVICIFocus and Goals

• California Plug-in Vehicle Infrastructure Coordinating Initiative

• Facilitate sharing of information and best practices among the different regional PEV readiness efforts, particularly North-South connection

• Serve a networking function and provide connection between problem identifiers and solution providers

• Send out e-bulletins on as needed basis identifying new findings and lessons learned


Participants

• Virtual meetings held with participants

• San Diego Gas & Electric• Southern California Edison• Monterey Bay EV Alliance• Bay Area EV Alliance• Sacramento Municipal Utility District• Sonoma County• Pasadena• Burbank• Glendale


Current Topics• Streamline Permitting Process

• Localities lack resources for permitting• Clear Checklist for Customers• ADA Accessibility• Multi-unit dwelling needs

• Gated communities, apartments, trailer parks --- different solutions for each case

Larger Topics • Home – workplace – public charging• User profiles of fleets vs individual owners

Topics


• Learn from OR and WA examples what worked in those states

• Distribute information to smaller municipal utilities, regions, cities that wish to get involved but often lack resources

• Develop a process chart with identified steps for PEV readiness

• Expand current funding support from SCAQMD and BAAQMD

CPVICI – Next Steps


Integration of PEVs with Electric Grid


• Integration of PEVs with electric grid will provide better use of PEV

• PEV are not only an electric load but can provide energy storage capacity and balancing of the grid

• The next steps in greater integration of PEVs with electric grid system need to be demonstrated now

Benefits of adding PEVs to Electric Grid


Integrating PEVs and Smart Grid

• “Smart Grid”• Integrating Distributed Generation• Increasing generation from renewables• Collaboration with JPL – Role of PEVs in Smart Grid Roadmap (CEC PIER funded)

Vehicle-to-Grid

• Vehicle-to-Grid refers to flow of electricity and communications between and electric-drive vehicle and the electric grid

• Two large sector that can be integrated• Smart interaction between vehicle

fleet, grid and intermittent renewable• Large, low-cost storage of electricity• Helps business case of PEVs

Recommendations

• We need targeted deployment of V2G now!• Need to show benefits in targeted

demonstrations• Discharging of EVs and other distributed

generation back to the grid provides greater benefit to the grid

• Use of stored electricity, grid stability, added generation capacity


Recommendations

• Encourage infrastructure projects be followed by test plans and monitoring of PEV use characteristics

• Design projects with fleets or aggregated vehicles – 50 to 200 vehicles (muni, gov fleets, campus)

1) Controlled charging2) Variable rate charging3) Discharging to grid4) Added functionality of on-board power

• Partners: Commercial fleets, Utilities, CalISO• With installation of ‘smart grid’ and charging

infrastructure deploy and test in parallel new applications and technologies such as V2G that really put the smart grid to use
