Bursting of Car Bubble

[SanDiegoDave]

They need to go back to the old way of making cars (from the 1970’s-80s era) when the cars would be completely rusted out, falling apart, junkers after only about five years of daily use. The car companies buried themselves by making the cars too well. Now everybody can just hold on to the vehicle they have during the economic downturn. Pump $50-$300/year or so into it for repairs and you’re set.

well you can trade the deposit on a tesla for a used Eclipse E500
in 2011.

I’m not that impressed with the Tesla. I think they’re all hype and very little substance. Did you know it uses AA batteries? I kid you not, go look it up.

Batteries are the heaviest single components in an electric car, so it makes sense to choose a cell size wisely. A AA battery has far more packaging than actual cell by volume that a larger battery would have. Maybe they got a good deal on AA cells, but it’s certainly an odd choice.

Someone I know, who’s an expert at power systems, interviewed there once and said the Tesla power systems engineers were pretty clueless.

Hogwash.

The Tesla does not use AA batteries. Someone I know thinks your expert is pretty clueless. Just because an individual cell is a SIMILAR size to a AA battery does not mean the car runs on AA batteries.

From Tesla:

We started our design by purposely picking a small form factor battery cell. This cell is called
the 18650 because of its measurements of 18mm diameter by 65mm length (i.e., just a bit larger
than a AA battery). Due to its small size, the cell contains a limited amount of energy. If a failure
event occurs with this cell, the effect will be much less than that expected from a cell many times
larger. Billions of 18650 cells are made each year. Though the chance of a safety event in a
laptop is small, the number of safety incidents involving Li-ion batteries is rising each year
because there are so many more devices using small and powerful power sources.

The Tesla Roadster battery pack is comprised of about 6800 of these 18650 cells, and the entire
pack has a mass of about 450kg.
