Silver Spring Networks (SSN) hosted an enjoyable and spirited 12th SF BayLEAFs meeting on Feb. 11, 2012 at their facilities in Redwood City. They have two ClipperCreek L2 charging docks that were used during the meeting (doubled up to charge 4 LEAFs). There were 48 in person attendees and 10 virtual ones, along with about 34 LEAFs , 1 Mitsubishi iMEV and 2 Chevy Volts in the parking lot. Please see above for a group photo, thanks to OrientExpress.
Besides the new members (several with LEAFs and another interested in leasing a LEAF) at the meeting, there was a special guest from Nissan Japan in attendance. Kawaguchi-san was the key contact who facilitated the visit by Kadota-san (LEAF Chief Vehicle Engineer), Nissan Japan engineers, UK Nissan and Nissan USA groups at the Dec. 3, 2011 meeting. We may have other interested Nissan Japan engineers attending SF BayLEAFs meetings if their schedules permit.

discussed their role in the EV community. The company connects utilities with their customers and transforms the delivery of smart grid services while improving energy efficiency, empowering customers and ensuring reliable delivery of low-cost services. Silver Spring is working with EV suppliers such as charging station (Electric Vehicle Supply Equipment or EVSE) manufacturers to integrate its Direct-to-Grid™ communications technology along with revenue-grade metering into those devices. This kind of two-way communications and data is essential for utilities to understand where EVs are in their service territory, adjust charging schedules, and protect valuable grid infrastructure. To date, Silver Spring has completed integration with the ClipperCreek Silver Spring-enabled CS-40 commercial EVSE. The company is working closely with the utility industry as they integrate charging docks with the grid.
As usual, there was an interesting discussion of the charging infrastructure, or lack of a viable infrastructure. psps summarized the outcome of the Agrion meeting held on Feb. 8, 2012 which he served as moderator. The speakers and topics are outlined at the link (http://www.agrion.org/sessions/agrion-en-Overcoming_Barriers_to_Charging_Infrastructure_Implementation.htm" onclick="window.open(this.href);return false
. One topic that was discussed is the ADA requirements on the roll out of EV charging stations. For example, the installation of charging stations at shopping malls and other business locations require ADA compliance, which can result in additional cost (for ramps, railing, restriping of parking lots, etc.). As an estimate, the regulations for installation of L3 quick chargers is about 3X that for L2 chargers.
ElectricVehicle discussed the progress in the charging infrastructure. There is some progress in the installation of L2 chargers at Walgreens and by the organization 350Green. With regard to Quick Chargers (QC), 350Green expects to deploy 24 QCs in Northern California. They are planning to install some of Nissan’s QCs. They currently project that some QCs will be installed by the middle of the year. ElectricVehicle is communicating with AAA to have one of their EV roadside assistance trucks available at a future BayLEAF meeting.
There was a brief introduction by gascant to the topic of the future direction of the SF BayLEAFs group. He will assemble a survey for the group members to provide input on subjects such as affiliating with other EV organizations or remain an ad hoc group, dividing the large group into smaller regional groups, interactions with Nissan, hosting demo clinics, etc. This discussion is in the formative stage but will be discussed in more detail at later meetings.
Some SF BayLEAFs received notification that there is a new software update for the LEAF. The exact details are sketchy but it is expected to improve CARWINGs, provide more realistic data on the mileage estimates and charging locations.
Several members described the cost of LEAF accidents. In one case a rear-end collision caused $1600 damage, which mainly involved replacement of the rear bump and some small parts in the trunk. In another case, a deer ran into the LEAF, causing $5000 damage. We heard from lemketron about the first case of the replacement of a faulty heater in the LEAF. In the process of removing the old heater, the dealer cracked the windshield, which he replaced for free.
surfingslovak summarized his effort on the “reverse (SOC) meter”. He kept detailed driving records that was supplemented with data from an SOC meter (Gidmeter) borrowed from gascant. His analysis suggests that the charging time at 120 V that is displayed on the LEAF dash is a good indicator of the remaining driving miles. Details on this topic is available on the web at

OrientExpress discussed his search for an electrical harness for the seat heaters in the LEAF that BayLEAFers have installed. He found one on ebay for the Altima that will work for the LEAF.
Plugshare has an iphone app that is reported to provide better information of public and private charging locations and LEAF data. Discussion on user experience with the app is on the MNL forum link http://www.mynissanleaf.com/viewtopic.php?f=27&t=7742" onclick="window.open(this.href);return false;
Electric4Me briefly described the receiver hitch that he designed for a bike rack and cargo carrier for the LEAF, and he did a demonstration of the installation on a LEAF in the parking lot. Despite the non-ideal conditions (bordering on inclement), he was able to install the receiver hitch in about an hour. Another budding BayLEAFer, his daughter, sewed a carrying bag for the hitch adapter, which can be removed when not in use. More discussion on the receiver hitch can be found at http://www.mynissanleaf.com/viewtopic.php?f=37&t=1552&p=171111#p171111" onclick="window.open(this.href);return false;.
As always, thanks to linkim for taking very thorough notes. The next meeting will be Sunday, March 4th at Luscious Garage in San Francisco.
