Tesla and Maxwell Technologies?

[Carl Raymond]

I’m reading a general expectation that Tesla will now reveal all on the Maxwell tech and what it means for batteries.

By all means, tell us how much cheaper it will make production of packs and how many billions that will improve the bottom line.

But please, do not say a word about how it will make packs better, not until such packs are in all cars being delivered. Learn from the Q1 S/X slump which arose from rumours of project raven.

Personally I thought Q1 sales slump was due to tax credit phase out.
People in USA rushed in Q4 2018 to buy before the phase-out started so sales rose then, and then dropped in 2019.

Maxwell merger is officially consummated. MXWL has halted trading. It will probably take a few days for MXWL shares to be replaced with TSLA shares in brokerage account records.

To add 1 kWh of ultra capacitor, you’d have to remove 30 kWh of batteries for an equivalent weight and cost. You gain power for very short term acceleration and hard braking events at the expense of a lot of range, slower charging and more cycles (wear and tear) because of fewer batteries.

Yes you could charge that 1 kWh of ultra-capacitor super quick, but then you have to wait for it to transfer to the battery, so you haven’t gained any speed other than in charging that very 1st kWh.

1 kWh of ultracaps (BCAP3000) would also put out something like 2000 kW of peak power, which is overkill, to say the least.

10-20 kg of ultracaps on the other hand would output 120-240 kW, which should be plenty to supplement the battery pack when it's very cold, while also acting as an energy buffer (60-120Wh) large enough to store the entirety of the energy from a stop with a starting speed of ~45-60mph. Tesla could also increase the size of the ultracap bank to enable the use of less costly/performant cells from other manufacturers.

I thought this was a good video on the Maxwell acquisition
