Case Study

Charge The North: The Largest EV Charging Study

I recently presented some of the results from Charge The North and wanted to share them here as well.

Program Overview & Data Collected:

  • 10 Electric Utilities

  • 1,000 electric vehicles

  • EVSE and vehicle agnostic 

  • 4,721 MWh charging energy

  • 727,000 charge events

  • 12.4 million miles of driving data

Summary of Conclusions:

  • EV charging load currently poses a risk to the distribution grid.

  • LR-BEVs represent a greater portion of EV market share today, than when initial recruitment was conducted.

  • Increasing occurrence of EV clustering will impact distribution grids at greater rates.

  • Beneficial opportunities to shift EV charging load exist for transmission and generation.

  • Territory factors (temperature, seasonality, TOU) can increase the impact impact.

Included in this post is the summary report. Please feel to reach out for the full report.

Increasing occurrence of EV clustering will impact distribution grids at greater rates

What's the cause of this-- when a public EV charging station has many outlets and is thus impacting all at once, or is it more a neighborhood that gets many EVs around the same time?

Thanks for the question, Matt. There are two main causes:

1. Suburban neighborhoods:

These are areas where the likelyhood of a household owning a LRBEV is high, combined with the increased probability that these LRBEVs coincidendal charging (both on household peak as well as when other LRBEVs are charging) occurs. Further, we are now also seing more than one EV per household in some cases. 
- Urban areas (Workplace and public charging) for the reasons you had stated in your question.

Scott Lepold : Keeping in mind the  existing situation of distributed Gazolene Stations, why do not electricty utilities go to innovative thinking such as microgrids dedicated to Charging Station.These new stations could be distributed through counties and built as needs arise. Each one has it own PV or/and Wind in addition to connection with the utility's distribution network as backing up (with net metering). Best Regards.

Hi Dr. Amal,

Thanks for your comment. Are you suggesting utilities should create a gasoline type environment/experience for EV owners in regards to how a utility deploys infrastructure? And then development them as microgrids? Are you able to explain further?
