Tesla unveils model 3

[morfiend]

LOL  ^^^

  Thanks for the heads up!  I have ballard in a tech portfolio so even if the went belly up it would be a huge loss and since I bought in in about 96,well I've done ok on it.

 I thought they made heavy duty cycle AGL batteries,for RV's and boats?  While ya they'd be heavy it's not like you need to move them around and other than some venting they shouldnt be a problem.  Many people use similar systems in the North in my country,and with a few solar panels the generator rarely needs to run.


  Or you could just use an anode and diode and some potatoes...

Meanwhile, Tesla vs 737, who will win?

Might want to read this before committing to going a million miles in any electric car.

Tesla has a battery exchange program in place. It can be changed in a few minutes. The price
of the battery will go down in time.One of the advantages of putting the battery in the floor is it can slide out to the side with ease. The battery degrades with use. A battery can give you 7 to 10 years of use if you are a local commuter.

The more electric cars that are sold will stimulate
research and development. New batteries will appear with higher densities that weigh less. Li is not the only
alkali that can be used in a battery.Batteries will become a very big business in time with many companies competing. Other technologies can provide electricity as well. Putting a track into the pavement on major highways would allow cars to run and charge at the same time. A given highway can charge a fee to use their electricity. Dick Tracey's world is here. I have one of his watches.  There is no limit to the use of the electric engine.

The electric engine will go more than a million miles. The major automakers do want to use them. The BART trains with electric engines where I live started running in 1972. They are still running with millions of miles.

I think your time frame for the battery life may be off, just slightly.

I can see a time where you do not own your battery or recharge it.  You pull up to the "Battery Exchanger" and in less time than it takes to fill your car with petrol, your old battery is trundled out and an exchange battery is rolled in for which you pay a fee.

And I have a flying car.

Everything you wanted to know about Tesla's battery pack, and more: https://teslamotorsclub.com/tmc/threads/pics-info-inside-the-battery-pack.34934

TLDR: Its a (massive) collection of temperature controlled (with liquid coolant) and fused blocks of 18650 Li Ion batteries.

The 18650 Li Ion is the most common Li Ion battery made.  Their properties are well known.

The following cause a 18650 Li Ion cell to die, ranked in order of severity: over-discharging, heat, over-charging, simple use, and time.

Tesla's software ensures that the cells never over-discharge and the environmental control built-in ensures the cells don't experience less than ideal temperatures.  However, Tesla charges their batteries well past the optimal voltage if one were to min/max in favor of longest battery life.  This is simply because min/maxing for longest life drastically reduces how much charge can be added to the batteries each cycle:

So Tesla has determined a balance point between long battery life and the degree to which they'll allow their packs to be charged up.  By charging to 100%, you push this balance point to its limit and reduce the life of the battery pack by some small degree.  In ordinary non-long-distance driving, you'll want to only charge your battery pack to 90%, or even less.  If you can do your entire daily routine plus unexpected local trips with only 50% charge, you could extend the battery life by only ever charging to 50%.

On the other hand, if you're driving long distances, you're min/maxing for range, not battery life.  You should expect to age your pack quicker.  To mitigate this, don't keep your pack at 100% for any length of time, only charge it up to 100% immediately before departing.

If they made batteries standardized and modular, this is actually feasible.  Probably would require robots at the changing station to switch them out.

It would cost a bundle to make it happen, but sounds more workable than hanging out for a few hours to charge your batteries or digging up highways to lay electrified tracks.


The current hybrid gas/electric powertrain is the most practical idea so far.   If only they made the Pious look more like a car and a lot less like a "I care about Gaia more than you do" statement.

Thinking there is a major, new, battery technology coming is like waiting for warp drive.

Keep in mind too, if there was a major swing up in battery cars the cost of electricity would sky rocket.

Elon Musk gets lucky with Space X also,  yesterday's successful  landing  claim to reduce space cargo / sattelites launch cost with 35%.
