Yesterday, we revealed an article by our good friend and Tesla proprietor Dan Zorrilla.

Quick ahead to immediately, and now we have a extra detailed evaluation from Sean Mitchell. As regular, Sean took the time to do some in depth analysis to be taught why this example got here to be.

The rationale Tesla’s 75 kWh battery goes away
As you could have seen, yesterday Elon Musk introduced on Twitter that Tesla will kill the 75 kWh battery for Mannequin S and X. Those that are desirous about shopping for ought to get their order in inside the subsequent Four days.
Not solely is that this a small demand stage to promote extra vehicles in Q1 2019, I consider there’s a bigger driver for Tesla.
This video will cowl my idea on why.
1. Bigger battery choices
We all know that Tesla has the flexibility to supply an extended vary car based mostly on what we’ve seen with the Roadster and Semi. What we don’t know is will Tesla use the present battery cells, the 18650 (18 mm x 65 mm), the 2170 (21 mm x 70 mm) or one thing fully totally different. Video: https://youtu.be/ifaE3DUJD34
Elon stated in an interview with MKBHD that doubling the modules of the Roadster would solely improve the quantity of the pack 80% or Four-5 inches larger. Video: https://youtu.be/MevKTPN4ozw.
The potential swap additionally aligns with the top of Tesla and Panasonic’s settlement of two billion 18650 cells introduced in 2013, which in accordance with my estimates has ended. Article: https://insideevs.com/panasonic-to-su…
2. Supercharger v3

notes that the charging cable on the Mannequin three seems to have the ability to take the next fee than S and X on account of its diameter. Video: https://youtu.be/rDYbvI32OBE
Lastly, if this isn’t convincing sufficient, Elon acknowledged not too long ago that V3 ought to arrive a while early 2019.
If Tesla strikes to 2170 cells for S and X, it ought to by nature of the battery structure have the ability to face up to an improve from 120 kW cost fee to one thing larger.
Each Elon and JB Straubel are on the report saying that they assume 350 kW is simply too excessive.
Right here’s what Elon needed to say on a Q1 2018 quarterly name:
“We’re undoubtedly going to be bettering our Supercharger’s know-how. The factor a few 350 kW charger is that it doesn’t truly make a ton of sense, except you bought a monster battery pack or have like a loopy excessive C ranking… We predict 350 kW for a single automobile; you’re gonna frag the battery pack for those who try this. You can’t cost a high-energy battery pack at that fee, except it’s a really excessive kW battery pack. So, (for us), one thing alongside the couple of hundred, 200-250 kW, possibly.” Article: https://www.teslarati.com/tesla-super…
If Tesla strikes to a 250 kW Supercharger this ~2x enchancment on it present 120 kW cost fee.
This might probably get a Zero-100% cost in about 30 minutes. If we apply Tesla’s present method of charging shortly on the entrance finish, then slowing down on the battery will get nearer to a full cost, we’d see an 80% in 15 or much less.
Might this additionally affect the dimensions of the battery in S and X? Elon has stated on a number of events that he doesn’t see the battery going past 100 kWh however maybe he meant based mostly on the 18650 cells.
