Minutes from 12/14/14 were read and approved.

The EV task force in St. Louis is having a meeting at Ranken Tech on Feb 27 at 10AM to hear from a company called “ChargeUp”. The company would like to install DC fast charging stations in the metro area. If Nissan approves the site, the company will provide equipment and monitoring. The property owner pays for installation. In Georgia, GA Power has covered the installation cost because they can make money from the charger.  In some cases the cost to the site owner is nothing.

The GEM neighborhood vehicle was discussed. The St. Louis Science Center has it in a warehouse nearby. Wayne, Dale and Josh looked at it last week. Most of the parts seem to be there. Wayne showed some pictures of the front and rear and the major components that are under the front dash panel. He showed some vehicle specifications from the owner’s manual. The vehicle was built around 2003 and is a 4 door vehicle built on an aluminum frame and fiberglass body. The hinge on the rear driver side door seems to need repair. Kyle knows how to work with fiberglass. The rear view mirror also needs to be reattached.

The GEM has a 72V system with a GE shunt motor and a Curtis controller with a rating of 360A. The GEM vehicle has 6  12V AGM batteries. Two are located in the front and four under the rear seat. As expected the batteries appear to be bad as they measure <1V. We think the major components are probably good and it just needs batteries and a good cleaning. Tyler said he could bring his ZEN vehicle over to test the components and see it the wheels turn. We would need to pump up the tires and move the GEM close to the dock to connect to the ZEN with jumper cables.

Ron E. had some information from Boston-Power on their new modular lithium battery packs. They are small cells that connect together to form series (higher voltage) and parallel (higher current) to make a large capacity battery. Wayne said, according to their literature, the energy density of these cells is 207Wh/Kg compared to the best large format CALB cells of 118Wh/Kg. The cycle life is claimed to be higher than 2000 and 90% depth of discharge. Ron thought that they may be interested in donating batteries to the GEM project as a way to publicize their product. Perhaps the Science Center could write a grant proposal for the batteries.

Tyler suggested that our club think about having some of our meetings at the Third Degree Glass Factory as a possible way to attract more people to the meetings. Perhaps a few spring meetings would work. Of course, we would still meet primarily at the Science Center.
