Video: Tesla Model S 60 kWh Now Supercharges at Over 100 kW Thanks to Firmware Update


Prior to firmware update 5.8, it’s been reported that the 60 kWh version of the Tesla Model S couldn’t charge at rates of over 70 kW.

There's 102 kW

There’s 102 kW

After the update, rates as high as 105 kW have been reported.

YouTube uploader KmanAuto continues to amaze us with his entertaining and informative Model S videos.  This latest one shows a 60 kWh Model S Supercharging at previously unseen rate.

An abbreviated (and slightly edited) version of the video descriptions is as follows:

“Well, proof is in the pudding. With the new 5.8 Firmware, the 60kW Model S can now supercharge at rates above 70kW.”

“Now, I have been able to charge at 88 kW in the past in Rockford, however, this is the first time I’ve been able to exceed that rate. On top of that, a number of people (myself included) have had issues at the new Mauston Supercharger not being able to get above 66ish kW, even on the new firmware and regardless of the battery pack size, weather it be 60 or 85. Well, I arrived in Mauston (barely!!!), and plugged er in. All I can say is, WOW… My car was just getting BLASTED by those Killer-watts!”

“So #1, the 60kW Model S Charging rate tops off at 105kW. And #2, Mauston’s charging speed issue appears to be fixed.”

Now, tonight, I had the most ideal circumstances possible (in my opinion) for Supercharging a Model S. #1, Pack was already at full operating temps, as I had just driven 150ish miles at 70mph to get their. #2, my pack was dead (0 Rated Miles Remaining), and #3, It was COLD out, 26 degrees, so cooling was in a fairly decent shape. Could have been colder though, but I think I got fairly close to perfect charging conditions.”

The rest of what occurred you’ll see by watching the 1-plus hour video above.

Wow.. I’ve never watched a supercharger in action before. It is amazing that he gained 5 miles of range in about 60 seconds. A 120V on my Leaf or Volt would take an hour for that same amount, or 30 minutes on 240V.

While this is good news for 60kWh owners, the real controversy is that there are thousands of 85kWh Model S owners who are limited to only 90 kW charging even on the latest firmware.

Apparently they have an earlier revision of the battery pack that can’t handle 120kW charge rates.

Currently Tesla’s position is “tough luck, only 4 minutes difference in a 10-90% Supercharge”, but many owners are doubting that figure.

Part of the controversy is that there was no clear cutoff or communication about the change leaving owners to guess what their car is actually capable of.

And people bought iPhone 1’s in 2007 for $600. As an EV nerd your frustration at the speed of disruption and leapfrogging merely ignites my technolust.

The controversy isn’t in the fact that Tesla starting improving the Supercharging capability of 85 kWh cars at some point in time – it’s that owners have no idea whether or not their cars are capable of 120 kW charging until they actually try it.

The controversy arises from the fact that Tesla said that all cars would be 120 kW capable and would be enabled with a simple software update, when they are not.

Comparing an iPhone to the Model S is not the same. You knew exactly what you were getting with the iPhone.

The folding mirror issue is not the same – one clearly knew you were not going to get folding mirrors before you got your car.

“only 90kw”……

There is not controversy the early adopters got diferent hardware. My tesla came without folding mirrors because I place my order one week before they release this future. Technology advance very fast and you have to cope with it, every 6 months the new cars will have something improved.

Spoiled Tesla Owners will want all the physical hardware updates, along with their free firmware updates. 😉

Then it definitely pays to wait as long as possible, and/or wait for disparate features to alter depreciation/used values.. Of course, Tesla could pull an Aston-Martin and make these features available to older vehicles via retrofitting, though one hopes the markup wouldn’t be too outrageous..

Waiting will never pay off as there will always be new features coming out–better to find a model that has the features you want. BTW, at least some of the HW updates (fog lights and apparently the folding mirrors) have been made available as a pars+labor retrofit.


Waiting for the Model X while they do various software and hardware improvements to the Model S seems reasonable if you’ve waited this long. Less than a year for the first Model X to be out. Would be a fun test in the midwest in this weeks weather.

Dr. Kenneth Noisewater

Beyond the (hoped for) cost drops due to larger scale battery production, I prefer a Model X for its increased size and dual motors anyway.

It’d be nice to see battery capacities per tier bumped with pricing staying the same at those tiers, the way Apple does when it rolls out updates to its products. Keeping the pricing the same but going from 40/60/85/P85 to 60/85/115/P115 would be nice to see!

Sounds like the computer days of 10 to 15 years ago. They were out of date almost as soon as you got them home.

And that has changed how, exactly???

What’s amazing is this is already 1/10th the speed of liquid fuel. Also amazing this is only a 60kwh lithium pack pulling in 100kw (although I’m sure it’s only a short peak pull in the middle of the charge). Consider that with a 120kwh 400 mile battery, you could charge at 20% of the speed of liquid refueling,: 200kw, 600-900 miles per hour. Bigger batteries are a win in multiple dimensions for EVs. Power, range, and refueling.

It’s at the beginning of the charge when the battery is empty.

Yeah, my mistake. IIRC, lithium cells take a charge at a level higher power over the first 60ish% and then start to taper slightly, and taper a lot more after 80%. So this 100kW might’ve lasted over filling most of his battery (video was too long for me to check it out myself, I’m not literally going to watch a kettle boil if it’s not my kettle).

Supercharging compared to everything else:

ou yea, he was really supercharged 😀

Supercharging is an interesting discussion, but several ev owners live in places in the country where no superchargers are ever planned (such as where I live).

I look forward to the day when cheaper, larger batteries make the news, thereby reducing the need for as many public chargers.

Charging after midnight is more grid-friendly anyway.

Tesla has said in the past that they would be happy to cooperate with other EV companies in connecting their cars to the Supercharger network.

Any EV company who hasn’t already began talking with Tesla on how to get their future 200+ mile range EV’s to work with the Supercharger network are fools.

They can all debate between other different standards until they are blue in the face. Meanwhile, Tesla is simply beating the tar out of everyone else.

I cant see other EV manufacturers willing to use the Tesla Standard for Fast / SuperCharging. The main reasons to resist might be:

1. Your company is legitimizing a new, disruptive startups’ EV technology.
2. Your company branding is nowhere to be found at Tesla Supercharger Sites.
3. Each time your EV customer uses the Tesla Station, Tesla reaffirms its brand / technology, directly to your customer base, due to #2.
4. You have to directly pay a competitor, Tesla Motors, to use the stations. The cost would be added to the retail price of the vehicle, making fewer people able to afford your product.
5. Tesla Plug / Data Protocols are proprietary designs, unlike global standards like CSS, etc. Licensing adapters and creating flexible onboard charging systems that support multiple plug formats, adds to the cost of your product.

Etc,. etc….

Actually, Tesla Superchargers apparently use the J1772-DC protocol. Tesla is part of the standards effort, but disagreed on the SAE Combo plug which is one ugly beast. Plus Tesla wanted to ship way before SAE finalized and Tesla couldn’t wait.

The problem for everyone else is that it isn’t clear who is willing to put the $50-200k in per CCS charging station. If it isn’t the car company, then who? At what rate? Nissan is sponsoring some CHAdeMO stations, but far too many of those are at Nissan dealerships which are not exactly positioned well. Plus their car doesn’t have to range to really travel long distances. Going 500 miles using 50kW CHAdeMO with a 80 mile range car will not likely be an effective solution.

I suspect the other car manufacturers will either license Tesla’s J1772-DC plug or have to sponsor the installation of their own L3 charging network.

Especially when I was able to do a 700 mile road trip in under 30 hours, would have been under 24 hours if it wasnt for 2 very bad snow storms. Thank You Tesla and My Model S 😉

the best car just got better
