@_baldtires 10%? would be typical of its axial load capacity, which from the picture looks like the point here

@4hmecl @Divergent3D Kevin is a visionary dude. And determined. You'd have to ask him, but I suspect some of the experiences from Coda led to parts of the Divergent thesis.

In 2009, when I joined a fledgling EV startup called CODA Automotive that ended up selling 140 cars and went BK, the CEO, Kevin Czinger (now @Divergent3D) told me prismatic LFP cells would change the world and formed a JV with Lishen, then the world's largest producer, in Tianjin. We also tried (and failed) to convince DOE to finance a JV LFP plant in Ohio. Post Solyndra and Fisker, the private and public capital markets went dark. It was too early, but boy was he right.

BREAKING: The U.S. Government has officially announced that @Tesla and LG ​Energy have signed an agreement to ‌build a $4.3 billion lithium iron phosphate (LFP) prismatic battery cell manufacturing factory in Lansing, Michigan, with a 2027 start of production. "American-made cells will power Tesla's Megapack 3 energy storage systems produced in Houston, creating a robust domestic battery supply chain," the U.S. Department of the Interior said in a statement. Here's everything you need to know about Tesla's new Megablock, the latest in the company's industrial storage product lineup, which includes the new Megapack version 3: Megablock: • 23% faster to install with up to 40% lower construction costs • Plug and play platform (hardware, software and services) delivered as one all from Tesla. It's a pre-engineered medium-voltage block that integrates next-gen Megapack 3 • Eliminated above ground cabling between the transformer and the megapacks using new flexible busbar assembly • 91% MV round trip efficiency • 20 MWh of usable AC energy • Operates in temps of -40°C (-40°F) to 60°C (140°F) • 248 MWh per acre • 25-year life & >10,000 cycles • With Megablock, Tesla is targeting to commission 1GWh in 20 business days, equivalent to bringing power to 400,000 homes in less than month Megapack 3: • Will be manufactured in Tesla's upcoming Houston Megafactory starting in late 2026. 50 GWh annual manufacturing capacity when fully ramped. • 5 MWh of usable AC energy • Weight: 86,000 lbs • 28 foot long enclosure that can be shipped globally • Optimized for up to 8-hour applications • New drastically simplified thermal bay. Uses Model Y heat pump, but on steroids. 78% fewer connections, which minimizes failure points • Larger battery module and larger battery cell • 2.8 liter battery cell, co-engineered with Tesla's cell team • LFP battery • Operates in -40°C to 60° • Went from 24 cable connections in Megapack version 2XL, down to 3 simple busbar connections • 75% of the mass of Megapack 3 is battery cells. • A single module in it weighs as much as a Cybertruck • Tesla has enabled easier front access service, so there are no roof penetrations • Drastically simplified bussing system

@faraz_r_khan It was around 3 years, loads of work and research, and finally I have something to show for it, as for the small/niche, definitely, not like I can make many more, and I don't want to sacrifice quality

@KipMock I wish. I think there are 2 reasons why: 1/ the generator that could convert 100hp to electricity would be quite large. 2/ most hybrid traction batteries can’t really sustain 100hp energy input. Both are solvable.

Hybrid vehicles with the ICE’s married to the electric drivetrain are a generational unforced error. Just make the ICE a generator it’s 10x better.

@KipMock yes, that’s called a series-hybrid (range extenders). they’re the best option for mass adoption in ev’s. I’m building around this

Dear EV fast charging networks, When I fill up my diesel car the petrol station provides me with a roof so I don't get wet in the rain. Howcome I must be drenched everytime I charge my car in the rain? Any chance of a roof/covering? Yours, A wet customer.
