A year ago, I shared a report called, 'Charge The North' which shared results from a 1000 electric vehicle load profiling study. 

We have now completed an new study called, 'EV Growing pains'. This report contrasts how EV load has changed over the past 5 years (2014-2020). 

Report Overview:

  • 3900 EVs across 40 makes/models included in the study
  • 28.9 M miles of driving data 
  • 761,096 Charging sessions 
  • 8,576 MWh of charging EV load 

Report Findings:

  • Rapid shift toward LR BEVs
    – Only 14% of EV market share in 2014 to almost 70% in 2019

  • EVs are driven further and more often, resulting in greater charging demands, but charging patterns are less predictable
    – 759 miles monthly in 2014 to 1,160 miles monthly in 2019 
    – Double the energy consumption per charge session from 9 kWh to 18 kWh  

  • Increase in L2 home charging
    – 63% of charging in 2014 to 80% of charging in 2019

  • Higher powered charging
    – 6.6 kW (2014 Nissan Leaf) to 11.5 kW (2019 Tesla Model 3)
    – More than double the average summer peak load contribution from 0.41 kW to 1.01 kW

Feel free to reach out with any comments, questions or a copy of the report.

759 miles monthly in 2014 to 1,160 miles monthly in 2019 

Any insight on how this compares to average mileage by non-EV drivers?

Yes. According to Car and Driver, the U.S. Department of Transportation's Federal Highway Administration says the average person drives around 13,500 miles every year, which is 1,125 per month.

Wow-- so it may be more noise than signal, but potentially EV drivers are driving more than their gasoline-powered counterparts? That'd be an interesting trend.

Hi Peter,

 

Thanks for the input here. I am going to follow back up on this thread in the next week or so. We are currently in the process of completing a public survey, and I think it may help provide some additional context and insight regarding range.

Cool. I'm looking forward to it.

I'm most curious as to the charging profile.  How does it fit into the current home non-EV profile?  Is it creating more impact on the grid at the wrong times.  Is it the first piece in driving a change of philosophy in grid design so now as electrificaiton goes, does the grid design change to handle a higher peak in reverse?

Hi Mike,

 

Thanks for your comment/question. To clarify, are you asking how EV load profiling and managing charging benefits all rate payers (ie. households who don't have an EV)?

Hi Scott:

Thanks for the post and information.

A quick question: I'm guessing that LR in "Rapid shift toward LR BEVs" is long range.

My sometime employer, Microgrid Labs works in the mass-transit segment of the EV market. I'm mostly retired and write a weekly post for Energy Central. A substantial percentage of these posts are on EVs (of all types). The link below is to a linked list of my posts that are sorted by catagory (read the Intro).

https://energycentral.com/c/um/list-papers-posted-energy-central-subject

Most of the posts regarding EVs are under "Mobility", but my most recent posts on this subject (2-part "Battery Day" posts) are under "Renewables & Microgrids".

Hi John,

That is correct - LR = Long Range.

Thanks for linking me to your posts. I will be sure to check them out!
