Transportation Analysis Fact of the Week #1045

77%-82% of Energy Put into an Electric Car is Used to Move the Car Down the Road

Unlike conventionally fueled vehicles, electric vehicles experience a loss of energy during “refueling,” with an energy loss of about 16% from the wall power to the battery during charging. However, electric vehicles are otherwise highly efficient delivering 60%-65% of the energy from the wall power to the road even before energy is reclaimed through regenerative braking. When energy gains from regenerative braking are included, the amount of energy used for traveling down the road can rise to more than 80% in the EPA-combined city and highway driving cycle.

Louisiana DC Fast Charging Corridor Master Plan


To create a statewide master plan for a DC Fast Charging network along our interstate corridors that also meets the standards for the FHWA Alternative Fuel Corridors signage.


On November 30, 2017, Louisiana submitted its proposal to the Federal Highway Administration (FHWA) for alternative fuel corridors. The state submitted proposals for three fuels along specific sections of our interstate system. On March 8, 2018, the state received notification of the approved signage-ready and signage-pending corridors. The fuels that received approval for corridors signage in Louisiana are CNG, Propane and LNG. The Louisiana Department of Environmental Quality (LDEQ) and Louisiana Clean Fuels (LCF) will now begin work with the Louisiana Department of Transportation and Development (LDOTD) to have the necessary signage produced so that the corridor is clearly marked.

The Opportunity:

The only fuel that did not qualify for signage was charging for electric vehicles. Under the FHWA guidelines, DC Fast Chargers must be spaced a maximum of 50 miles apart, each within 5 miles of the interstate in order for the corridor to be eligible for signage. To jump start the development of an electric charging corridor along our interstate system, LCF proposes creating a DC Fast Charging Master Plan for the state of Louisiana.

The Plan:

LCF has assembled a team of data experts, OEMs, EVSE experts, electric utilities and MPOs to begin work on a two-part plan. The first part of the Master Plan is to create the business case for potential DC Fast Charging sites that is backed up with comprehensive data which will aid in identifying the best locations for DC Fast Chargers along our interstates. LCF will collect highway data, economic data of the potential sites, and vehicle data from multiple sources along with existing infrastructure. The data will be used to conduct analyses and modeling that will reveal optimal DC Fast Charging sites in Louisiana.

The second part of the Master Plan process is to conduct regional outreach meetings in the different planning commission / MPO territories across the state. Both LCF and LDEQ will host these round table meetings with area businesses, utilities, and elected officials in order to facilitate local acceptance and demand for EVSE charging infrastructure along their critical corridors.

EVSE Site Ranking Criteria

LCF will prioritize locations around the state for possible DC Fast Charging EVSE installations utilizing the Sawatch EVSE siting analytics and site ranking criteria such as, but not limited to:

  • Access to shopping and dining
  • Access to a recreational facility
  • Safety (well-lit, low-crime)
  • Electrical Capacity (408 volt, 3-phase power)
  • Within 5-miles of an Interstate
  • Preferred by utility service provider
  • Preferred by local government
  • Co-located with other Public EVSE
  • Co-located with Tesla Charging
  • Co-located with a hotel
  • Publicly accessible parking garages

How can you help?

Sponsors are being sought to fund the Louisiana Statewide DC Fast Charging Corridor Master Plan. All funds will go directly to paying for Phase 1 of the plan: acquisition of data sets and fees paid to LCF’s contractors for the modeling and analysis of potential sites along our interstate corridor. The completed plan will provide a business case for potential DC Fast Charging host sites. All sponsors will get access to the final plan for three months before the Master Plan is published. Additionally, entities from all sponsorship levels will be invited to participate in the Master Plan committee meetings, regional outreach meetings, and will receive recognition in all press releases and events related to promotion of and/or completion of the study.

Thank you to our sponsors!
