The difference is autonomy day was a demonstration of what they HOPE to achieve. Limited test drives under controlled conditions, lots of technical talk about board speeds and AI approaches...but not enough to see. We already know most analysts have a complete inability to visualize the future. To many FSD seems far-fetched.
Everything we've heard about battery day is that it will be a demonstration. Working product right there. Harder to turn that into some nebulous aspiration for the future.
From my point of view, and not meaning to diminish the value of battery day (at least to me), anything in the way of a battery demo is going to be hard to visualize.
For example:
- This battery packs more energy per unit weight (which has this consequence). We're excited, but that's info that goes onto a slide, not a very good demo.
- Or similarly, this battery has more energy per unit volume (as above).
- I know that many here are excited about the million mile battery. I'm interested as a technology - I think the market is going to give that a short term incremental value of 0 (it doesn't move the needs for the cars being sold today; if they've got evidence of volume also available and how that increases margins and revenue in the energy business, then that's good -- and again, it goes onto a slide).
I think the good demo will be Model S / X with new technology batteries. Tell us that the new battery technology enables 200kwh battery packs in the same space and weight as the current 100kwh packs; that we get higher discharge rates which means (faster accel, faster charging at supercharger), and then have the new and great S/X there on hand for test whooshes.
And tell us about how Tesla is entering the cell manufacturing business for this new tech, and aiming for scale, and how this is going to lower Teslas already low battery cost.
I guess the 2 things I hope to hear about at battery day, and which I believe can move the needs on the share price around that date are:
- bigger batteries in current form factors / weight (with better performance)
- Tesla entering cell manufacturing, enabling Tesla to lower their cost for battery packs to $x (Tesla reporting an actual $/kwh or whatever for their batteries - THAT will move the needle).
Otherwise, I see battery day as primarily information for those of us here who are long term investors. Battery day this year is going to be foundational to Teslas competitive position in 5 years.
