Way to go, Wayne! Astonishing results!
That 22-State, 20k mile, Electrify America (EA) nationwide charging performance and reliability improvement project really improved the final Guinness World Record (GWR) result. Before the network and vehicle upgrades, the LA to NYC result came in at just over 4.5 hours. After the SW upgrades thanks to the charger performance study, the final GWR result was just under 2.5 hours.
2020 - 2022 Porsche Taycan and 2022 Audi e-tron GT owners will be the beneficiary with a measurably faster and more reliable charging experience for the foreseeable future.
Edwin, I wish you and Bill were along on this one. It was a lot of work but also a lot of fun.
2021 Porsche Single Motor Battery Plus Top Speed
The 148 mph top speed was achieved in the Mojave desert on a non-public accessible roadway.
I don't think any Tesla has gone that fast.
Or recharged so quickly.
Maybe we’ll be able to see how quick the battery pack is worn out, with all the speeding & fast fast fast charging.
But, even fast ICE cars weren’t designed for longevity, except to reach the end of the 24 Hours of Le Mans & other endurance races.
Bill linked a site describing how the OEMs control the DCFC in order to make the traction battery last for hundreds of thousands of miles. You can charge at 3C up to almost 80 percent and no OEM allows charging rates that high above 50 percent SOC. If a preheat of the pack is not completed or you arrive with to high a SOC when plugging in, the OEMs numerous charging profiles are far below the maximum rate allowed to protect the pack and they are strictly adhered to. Even if you achieve the max rate charge profile, as soon as you have completed DCFC with that last 15 to 20% at L2 rates, the pack is quickly cooled down which is the another key to the design.
So yes, these packs are designed for longevity under DCFCing using the various control limits previously discussed.
It’s sweet to know that 99% of the battery packs will last 300,000 miles & large percentages will last 500,000 miles, using 450 kW chargers & 800 Volt & 400Amp EVs.
Yup. Same thing is happening with the Tesla's now.
Yeah, the Tesla 4680 battery is supposed to go 500,000 to 1 million miles. Is that with 450kW, 800 Volt, & 400 Amp charging, too?
The 2022 Porsche Taycan in possibly Cherry Metallic is arriving tomorrow. It may also be Frozen Berry Metallic? I have to head into the desert for some media shots so we will see how that goes. I will try and get a full 5 to 80 percent charge on video so you can see it in motion. I had a number of those during the LA to NYC GWR but they were only setup for documentation, not detailed analysis. To see it in real time is truly amazing.

2022 Porsche Taycan
Frozen Berry Metallic
It arrived. It includes the adaptive air suspension that I was hoping for on the Guinness World Record car too! And a few more upgrades including glass pano roof, black suede interior, and 14-way power seats with memory to name a few.
2021 Porsche Taycan
I hope to figure out the suspension lowering system before to many more miles are placed on this beauty!
This one is going to be expensive but I wanted to know.
I drove the Taycan down to 0% SOC and 0 miles range - do not try this at home folks , reset the L2 Mustart home charger, took a pic of the Mustart L2 display, plugged in, took a pic of the Mustart L2 display once it settled down after approximately 90-seconds, and took a pic of the Porsche lower central display set to KW. The time was way off for some reason?
Here are the initial Mustart L2 Home Charging details for the 2021 Porsche Taycan. The 40A Mustart is just about maxxed out providing just under its max rated current of 40A. The Taycan can take up to 11 KW or a 50A L2 home charger but I do not have one of those. Next review vehicle upgrade maybe?
Home L2 Charging the 2021 Porsche Taycan
I charged the Taycan from 0 to 52 percent on 43.98 kWh. The initial charge rate of 8.9 KW was at 8.8 KW when I pulled the plug at 52% SOC so that was solid. 0 to 52% took 43.98 kWh so 0 to 50% - I missed it by a few minutes - found the Taycan taking in 42.3 kWh or 84.6 kWh vs the 84 kWh useable. .6 kWh is not much of a charging loss from absolutely flat to full while on an L2.
