Musk & Barra Love Child: Battery “Super Pack” From A TMS Perspective
Crazy High C Rates! It’s a conceptual marriage of the Tesla ribbon-style cooling system and the Chevrolet Bolt EV’s Prismatic-shaped pouch cells. We eliminate the bottom cooling plate. Once we start cranking up charging rates, pack cooling becomes a big issue. We’re sure that Porsche is learning the hard way since they have promised some […]
Tesla Model 3 Battery Can Transfer Twice The Heat Of Model S P100D
Track Data backs up our detailed Thermal Analysis In a previous article, we explained in words why the Tesla Model 3 battery cooling was much improved. To summarize that article, the main reasons are better heat transfer between the cells and the cooling tube (because the cells are now glued directly to the cooling tube), […]
A Little Secret GM Isn’t Telling Us About Improving The Bolt EV Battery

Tesla Model 3 Battery Cooling Much-Improved … Track Mode?
Tesla Model 3 battery cooling is significantly better than that of the Model S and X for multiple reasons. In most of our past articles, I have teamed with Keith Ritter (HVACman) who is an ME and a licensed HVAC engineer in Redding, CA. We now have a new and third member of our team, […]
You Think The Tesla Model 3 Supercharges Fast Now? Just Wait …
We are estimating 626 miles per hour charging speeds on Gen 3 Superchargers for the first half of the charge. In a previous article, we reported that current Model 3 owners are getting Supercharging speeds of around 460-480 miles per hour on Gen 2 Superchargers. That’s a big improvement over Model S owners that only […]
Is Tesla Shipping Model 3 With 2X Model S P100D Supercharging C Rate?
Turns out 2 times the rate and puts the Tesla Model 3 right in line with Tesla’s version 3 Supercharger. *Based on a published Tesla/EPA Document There’s a very interesting thread going on right now over at Tesla Motors Club Forum. It’s along the…
Tesla Model 3 Battery Has Power To Spare – Ludicrous Mode Anyone?
The Tesla Model 3 “P” version has 500 HP available at the battery but uses only 95% of it – we do the math Even without Ludicrous Mode the P AWD Model 3 is already quicker than BMW’s M3. Our calculations show that the P AWD version of the Model 3…
Has Tesla Changed How It Controls Front & Rear Motors For Model 3?
The theory is that the rear motor is now the “cruise” motor which is opposite to Model S. Consider this a bit of speculative forward thinking. Tesla has not said they have changed the way they control the front and rear motors. However, they have given…
