CCS chargers were pretty sparse north of San Francisco when we leased the i3 (all the way back in September). But since then NRG / eVgo has put CCS/CHAdeMO chargers in San Rafael at the Northgate mall and at the premium outlets in Petaluma for people who want to go up to wine country. We decided this was a good excuse to use our Charge Now cards that came with the car before the end of the year to get free charging until the end of 2015. I activated the cards online first and everything went smoothly at both chargers (there was a bit more drama when we used the Greenlots CCS charger in Point Reyes a few weeks ago). The CCS chargers in San Rafael and Petaluma are both ABB Terra 53 CJ models rated at 50 kW, 125 A, 500V. I also learned that if you use your Charge Now card, the charger will shut off once your free 30 minute session is up. I took a bunch of datapoints during each charge session (I repeatedly snapped photos of the data on the charger screen for lack of a more elegant solution). I can post the data on how long it takes to reach various states of charge if people are interested.
