Simple solution: when charging at home, *only* charge the car during off-peak periods like at night.

And, as utilities upgrade everyone to TOU smart meters, well, that's a heck of a lotta incentive to charge off hours only!
I don't think this will be such a huge problem. How often will the average guy need quick-charging at home?
Assume that I get home with an empty battery at midnight (which would be a very unusual event in itself) and that I need the car by 7AM the next morning. I let the charger draw 16A, 230V throughout the night. That would add up to 25.8kWh, which would mean at least 22kWh in the battery, yielding a range of about 150km. That would usually be plenty. 10A would yield about 100 km, which would usually also be plenty.
This can be solved by having the car ask "When do you need me? How much range do you need?" when you plug it in, and then adjust the charging rate accordingly.
Road trips would be different, but that is not the common case, at least not in residential areas.

I looked into a TOU meter here in MD. The utility would charge me $15 per month to have TOU. That's more than I would save charging my Roadster at the off peak rate. Result: I don't move to TOU, and they lose me caring about when I charge my Roadster.

Here in CA, the utilities are incented to have customers save power instead of using it. It's a model that's likely (hopefully) to be replicated across the country as the pressure to become efficient increases.
I was at 70% usage during night hours and ready to switch to TOU in NJ but, I picked up a MINI E that needs to do 70+ miles around home per day & that means plugging in after each trip; it only has a 65mile range on a bad day; cold.
I used to charge the roadster at 10pm but now I charge on plug in to take advantage of the battery already being warm.

PG&E's TOU schedule in winter has 5-8pm as semi-peak, everything else is off peak, including all weekend. And the semi-peak rate is barely more than the off-peak rate. TOU is really targeted at summer afternoons, to chop the top off of peak demand.
I understand the advantage of an "already warm" battery in the winter, and would generally agree. But -- IMHO -- due to the HUGE thermal mass of the ESS, a few hours having "cooled off" in the garage should not make a huge difference in charging efficiency (it will be a few degrees at best), but could make a large difference in the TOU electricity cost/kWh. If the Roadster is parked outside at below 20F for more than 4 hours that would change the efficiency more significantly, of course.

On reflection, I agree, I'll set it back. It might have the knock on effect of leaving the battery warmer in the morning so I don't loose regen.

ECOtality, Inc. Announces Filing for NASDAQ Listing
Phoenix – February 16, 2010 – ECOtality, Inc. (OTCBB: ETLE), a leader in clean electric transportation and storage technologies, announced today that the Company has filed an application to list its common stock on the NASDAQ Capital Market.
“We believe the move to the NASDAQ Capital Market is the next logical step in the Company’s future growth and will allow our Company to gain exposure and be recognized by a broader segment of the investment community,” said ECOtality President and CEO Jonathan Read. “With rapidly increasing operations within the United States and increased activity in the international markets, management believes now is the time to move to a larger exchange. As we move forward with the deployment of EV infrastructure on a global scale, a NASDAQ audience will allow us to attract additional investors and improve shareholder value.”
In the U.S., ECOtality’s wholly-owned subsidiary, eTec (Electric Transportation Engineering Corporation) is the project manager for The EV Project, and will oversee the largest-ever rollout of electric vehicle infrastructure in the United States. Last fall, the U.S. Department of Energy – through the American Reinvestment and Recovery Act (ARRA) – awarded nearly $100 million to create that infrastructure, support renewable energy and most importantly, to create jobs. With a match from partners, the total project value is approximately $200 million.
Globally, ECOtality continues to expand. Earlier this year, the company announced creation of ECOtality Australia Pty. Ltd., headquartered in Brisbane, Queensland.
The company is already seeing success there in its marketing and distribution of battery-charging equipment to on-road electric vehicles (EV), industrial equipment, and electric airport ground support equipment (GSE).
In 2009, ECOtality also entered into a joint venture with China’s Shenzhen Goch Investment, LTD., providing $15 million to establish manufacturing and distribution for EV charging systems in China.
The NASDAQ listing application is subject to review and approval by NASDAQ’s Listing Qualifications Department for compliance with all NASDAQ Capital Market Standards. NASDAQ's review process is thorough and may take an extended period of time before completion. While the Company intends to satisfy all of NASDAQ's requirements for initial listing, no assurance can be given that its application will be approved.
