...A new corridor of 30-minute fast-charge stations launched Monday in Northern California. When it’s fully operational next spring, it’ll include more than 20 locations between Monterey and Lake Tahoe...
...installation of the 50 fast chargers along the corridor is expected to be completed by March 2017...
Who is funding the project?
As part of its mission to improve energy conservation and promote new energy technologies, Japan’s largest public research and development management organization — New Energy and Industrial Technology Development Organization (NEDO) — is funding “DRIVETHEARC” project...

I hope that something was lost in translation in the release below, and that the new DC stations will actually provide opportunities for large numbers of DC Capable BEVs to charge simultaneously (providing reliability) that they will be located where BEV drivers want to use other facilities and that the guidance will allow those seeking DC charging to easily filter out the masses of slow AC sites and unreliable or unavailable DC charge sites.
If you click the link and look at the central California routes mapped, ~only the highway 50 and 80 routes from Sacramento to Tahoe are still lacking DC charge sites (such as they are) so let's hope the new stations proposed on those and the eastern routes are not just more of the same.
NEDO asks Nissan and Kanematsu to analyze EV use in California
...The NEDO project will seek to encourage the use of electric vehicles for longer distances and inter-city driving by installing and maintaining multiple quick chargers along specific inter-city routes. Nissan and Kanematsu will collect and analyze data on EV driving patterns in California, and create a suitable model to help promote more extensive use of electric vehicles in the state and beyond.
With the help of the California state government, and U.S. utility company NRG eVgo*, Nissan and Kanematsu plan to place additional quick chargers at suitable locations along inter-city freeways in Northern California, and use project-specific information services to guide EV users to the most efficient chargers along the route. The companies will then assess whether the combined hardware/software model can successfully encourage users to drive longer distances in EVs.
Nissan's role in the project will be to install and operate the quick chargers, and analyze any changes in EV use that result

California ARB receives VW’s 1st $200M, 30-month ZEV investment plan

Even if they start increasing the potential rate of charge on new cars in the future, there has to be an electrical (physics-related) limit on how fast you can charge a battery. People seem to be thinking that we will be charging in 5 minutes (like filling up on gas) in the near future... IT IS NOT GOING TO HAPPEN...
We try to understand the fast recharge capability of Li-ion batteries and its effect on capacity degradation. We find out that 5 Ah prismatic Li-ion cells can be fully recharged in 3 minutes under a constant rate of 20C, or in 2 min (25.5C) from 0% to 85% SOC (state of charge) without undue stresses. We cycle the battery at 16C charge rate from 0 to 100%SOC and do not see any unexpected battery capacity loss in 50 cycles, where half of the cycles are 1C-rate charge as a reference capacity check. We realize that the batteries under the fast charge study do not experience mass transport limitations in either solid electrodes or the electrolyte system.

If the LEAF had active cooling, I suspect that the batteries would not suffer any significant amount from QC, even if you pushed the charge rate faster. It's the elevated cell temperatures from QC that primarily accelerates the rate of capacity loss.

Guess which one I use?
- EVgo's DC charger, at $10+ a pop
- Chargepoint's DC charger, which is free
(Oh, if you count the SMSA, there's an oddball, a Greenlots DC charger--also free--about 15 miles north of town.)
I feel bad for people where EVgo is the predominant network... that's damned pricey.
