Speed Kills? Not Here!
Back in July, we posted on the efficiency of electric vehicles, or EVs, using miles per kilowatt as the metric. You can see that post here.
But whose electric vehicles have the fastest charging speed?
We promised to then post on charging efficiency or charging speed when DC, or Level 3, charging. This proved to be a really difficult nut to crack as manufacturers throw numbers around that are near meaningless and mostly self serving. Whatever number makes their car or cars look good, they will use. There is no standard metric. Or at least there wasn’t until now.
The Real Pros
Enter Edmunds.com. Working with P3, they have the resources and the access to do this properly and have researched the topic which has culminated in their article, Which EVs Charge the Fastest? The link will take you there.
So we will defer to them on the topic — they will do it best, and have already done it. By all means when doing research on your next or first EV, check out their work.
They tested charge rates when batteries are at 10% charge and charged only to 80%, which is exactly how you should charge your car at a DC or Level 3 charge station. By stopping at 80% charge, you spare a battery’s overall lifespan and better maintain its long-term performance. Charging power for most, if not all, vehicles also significantly slows beyond 80% (see the charge curve and discussion below), so it’s generally best to unplug at that point. Its the best use of your time as well as the car’s battery and frees up the charging station.
We’ll make one notable observation. In our efficiency research, Hyundai’s fleet was second only to Lucid and tied with Tesla. You can see it in our previous post. Edmunds testing places two Hyundai models and one Kia — same manufacturer — at the very top of charging speed! So, not only does Hyundai come in with the best range but many of their models charge the fastest as well!
Edmund’s leaderboard is here. They use an interesting metric of miles added per hour while DC charging, leading to numbers that do not reflect range! The Ioniq 6 adds range (charges) at 868 miles per hour! This does not mean that the car will go 868 miles when done charging. It means it will hit its roughly 300 mile range and be done charging well before the rest of the field!
The next fastest charging model that is not a Hyundai or Kia is the Porsche Taycan at 690 miles per hour, a full 20% less. The first Tesla is the Model 3 at 569 mi/hr, 35% slower than the Ioniq 6.
A final note here. All EVs feature a charge curve, like the one shown below from P3. It’s a little difficult to read, but reading it is not the point (you can read it here). All of vehicles shown behave in a very similar fashion, and yours will too. They start fast and finish slow. It is the nature of today’s battery technology and stopping at 80% is best for you, the battery and the charging public. Adding another 10% could take as long as the first 70!
