  • But, it doesn’t change much, really. Folks need to move on from charge rate fetish or go deeper.

    My >5 year old Tesla does 250kW, this says 1000kW But - you dont actually charge 4x faster at 1 MW. Nor do you want to. 250kW doesn’t charge 2.5 faster than 100kW either, in my experience. This is because this is the limit, not the average. And the averages are slower for many reasons. Including you dont want to slam energy into your very expensive battery that much faster than you take it out, it will wear it out.

    And you know what? 100kW is good enough to charge over a meal or store visit. Packs are usually less than 100 kWh, and sessions are <<100%. And plugging in longer at level 2 / 11kW is better for the battery and grid if you’re in no hurry.





  • Precision and volume are the key metrics. They have precision here, but it looks like they won’t get volume.

    “E-beam lithography machines cannot produce chips at a large scale like Dutch company ASML’s DUV and EUV lithography systems, but they excel in the testing stage of production, offering high-precision circuit patterning and design flexibility. Priced lower than imported machines, Xizhi can pattern circuit lines as narrow as 8 nanometres, with a positioning accuracy of 0.6 nanometres – matching international standards.”
