IMO the move was done out of necessity.
The keys to having the concept of electric car take off, are
1 the availability of fast recharging stations everywhere. For the companies (*) to invest on this, there has to be a massive move from all car manufacturers toward electric car, the sooner the better. Therefore the more proprietary IP becomes public, the sooner this will happen.
2. The low cost, small size, problem free operation of Li technology batteries.
Don’t forget that the biggest risk and bet for TESLA is not their car, it is their battery super fab. They desperately need other car manuf in the game, otherwise with less demand for batteries, the cost per battery will not be as planned, thus the investment in the fab will not be justified ( a major partner expressed his concern a month ago)

(*)bonsai If you look around, all the major petrol multinational companies have invested heavily on any other energy source. They will not stay out of this game, whether we will see their names with neon lights or not
Large capacity energy storage as done today is hard to beat
Pumped-storage hydroelectricity - Wikipedia, the free encyclopedia
This is very true Kindhornman. Feeding an electric grid through different energy sources and having a single kind energy demand (electric load)
But I agree with you that the push on us for new cars is not energy-saving driven
George
The BIG problem is electricity supply infrastructure....every house drawing an additional 5kW++ overnight.
Dan.
Very true. The UK's grid assumes an "average" of around 1.5kWh per household when network capacity is considered. At some future point there is going to be a big big problem... not just with distribution but generation capacity as well.
We (our locality) are currently under a new trial to reduce supply voltage automatically at peak demand and so reduce load on the grid.

Kalimera George,
While I agree with your ideas, I must point out that no one single manufacturer is likely to make the big break in batteries alone.
For that to happen, we would need to have industry standards of mutually interchangeable batteries in say three sizes. Then you could got to what is today a petrol station and have your auto battery type A exchanged for a fully carged same type battery. Your battery is immediately put in the charging cradle.
Just as we have AA and AAA size batteries, not all vehicles would abe able to accommodate the same size, hence the need to have three sizes. Advanced models could use one type A and one say type AAA battery, or some such combination.
If this was a service available across a country, then it would become a viable project. The EU could shine here, creating continent wide standards. Then, everyone else would have to jump on board if they want to sell in Europe, and these days, EVERYBODY wants to sell in Europe, even the Big Two from Detroit (the Third, Chrysler, is already owned by FIAT). Heck, I own a Chevrolet.
Not to even mention the dropping cost of the batteries as such, once their manufacturers were facing a demand of say 50 million per annum.

Uh hah...I don't understand how reducing supply voltage will reduce overall demand.
For resistive loads, some power reduction, but active loads like electronic devices will pull more supply current.
Dan.
The Vanadium link does work.

Exactly! All those SMPS devices and wall warts will put increased current demand on the cabling. We are all electric (no gas) and pull around 17/18kWh worst case, although that is off peak between 00:00 to 07:00
Certainly makes you think though.
What you would want to do with a device like this in the field of audio could be done better with THAT Corporation 1200-series InGenius High-CMRR Balanced Line Receiver ICs
Yep , still a few man months to go ....
Still, amazing what a few weeks with an SR1 can reveal
