May 2013:

US Air Force Academy Solar Installation

 
Saturday May 18th - 10:00 AM
US Air Force Academy - Colorado Springs
 
Saturday May 18th at 10:00 AM, tour of the 2 Megawatt Solar Array at the Air Force Academy near Colorado Springs.

The May meeting was held at the Air Force Academy Solar Array on Saturday the 18th with nine in attendance, including the two guides. We were shuttled into the area, from the parking lot; in a cadet project dune-buggy-looking EV. It has a 45 KW 3 Phase AC Induction Motor, powered by a 345 Volt, 12 KWh LiPo Battery Pack, via an Azure 3 Phase AC Controller. The opportunity was given to anyone who wanted to drive it. After Drew Galo, our web master, took it for a short drive, he was ready to take it home. We then checked out another cadet project which was a Mobile Power Station which is fed by a 300 watt solar panel (like the ones used in the solar array), plus a small wind generator. These charge the LiPo battery pack, which in turn powers a 120 VAC inverter. There is a step-up transformer for 240 VAC, which in turn could power a 3 Phase AC Inverter. If they haven't got the type of power that you want, you didn't need it in the first place. Another feature is you can send a text message to the Station via cell phone and it will text back the information requested, such as battery pack state of charge.

With Colorado's alternative fuel vehicle tax credit, Coloradans can receive up to 85% back on a plug-in conversion - that means you can convert your Prius for under $1000. Boulder Hybrid Conversions is a collaboration of people who have been involved with hybrid conversions and electric vehicles for several years. Together, we have completed over 50 successful hybrid conversions. Our goal is to help Colorado get more and more plug-in vehicles on our roads.
 
EVolve Electrics, one of the premier electric vehicle component distributors, shares space with Boulder Hybrid Conversions. EVolve provides lithium batteries, BMS, motors, controllers, and other EV components.

Long-Time DEVC member George Gless passed away February 6, 2011


Memorial site and memory book
 
I admired and enjoyed George's company for many years. I seemed to gravitate toward George and Jean because of their kindness. They provided a very nice pass through (which never was less than an hour)!!! I rode my bike by their house and whistled at Kelly, would see George under a car and Jean smiling at whoever came near. George was an important person for me to know as I met George the same time I got into the EV business. He looked and tweaked my EV's I had for years. It was his eyes, they seemed to defy machinery many times-or I guess the eyes of an Engineer!
 
I really feel lucky I knew you George! You were one of a kind!
 
Your friend forever!

High efficiency vehicles being his specialty, he also drew a line in the sand by taking second place at the Human powered vehicle races, in the E power challenge, going 32 miles in an hour, but only using half of the fuel as the previous winner, at 12 watt hours per mile. Combining years of research and experience, Josh looks forward to creating a distribution network for the E bike industry.

DEVC Meeting - June 12th


Don Missey. Don has an extensive background in large public works projects. He is associated with some emerging technologies which are gaining traction as transit options. His biography includes:

Mr. Missey has nearly two decades of experience in project management, cost estimating and financial modeling in transportation and energy projects. He has built a number of detailed cost models for underground transit systems beginning with the Boston CA/T, and has written extensively regarding ‘lessons learned’ and the causes of project failure in the transit investment and energy generation sectors.
An undergraduate of Indiana University in economics with a concentration in transit at the Kelly School of Business, Mr. Missey's academic focus at the graduate level has been analysis of the causes of investment failures in transit and energy projects, and lessons learned. His approach of applying nomenclature familiar to engineers regarding project failure to new areas of investment management has been applied to the Segway personal vehicle, ethanol plant development, DIA baggage claim, Shoreham Nuclear Power Plant, Boston CA/T, the Washington Public Power Supply System (WPPSS) bond default, and a number of other current and controversial project failures, some still in the making.

Mr Missey’s most recent focus has been on developing sustainable intermodal transit and transport revenue models, including light personal vehicle development. www.prsvcs.com

Report on EV race at Frederick HS, May 16th - by Bill Williams


There were five cars in evidence Saturday noon at the Frederick High School parking lot. One was from Frederick HS, one was from Front Range Community College, one was entered by Pete Robustellini, and two were brought by Fossil Ridge HS in Fort Collins. Pete rolled the "Orange Sneaker" four wheel car out of his truck ready to race while Nicole Sixberry had the Fredrick HS #16 ready to go at the drop of a flag! Anthony Belcastro from FRCC had the green and red former Ken Jones, former Zelazney, front wheel drive tricycle in it's best shape ever. Finally the two aluminum framed, cars from Fossil Ridge HS, were unloaded.
 
John Thayer's team had brought their older rear drive tricar #2 which, operating on borrowed batteries had throttle problems and ultimately was unable to start. The new Black and white #1, a four wheel, rear drive car, started but also had throttle control problems and made only one lap before retiring. Paul Colasunno, the driver, must have felt disappointment at this failure. Both cars were deficient in the rear view mirror area and there were sharp interior objects that caused concern. Still with their powerful brushless DC motor/controllers they should be quite competitive when sorted out!
 
At the drop of the flag the four cars were started in 10 second staggered intervals. FRHS #1 pulled off very slowly causing speculation about their choice of a high drive ratio. It made one lap and pulled off with throttle pot problems not to be seen again!
 
FRCC and FHS cars both got off to slow starts, clocking only four laps in the first 10 minute period. FHS was throwing the chain but had gotten very good at reinstalling it! The FRCC malady was less clear but after 20 minutes they had cleared it up and Finross Jarrar gave it a good run. If they had run the first 1/3 of the race like they ran the last 2/3 they would have been in a very strong position to contest for first place! As it was they took second place with 58 laps!
 
Matthew Evans was patiently coping with the chain problems of car #16, eventually arriving at an arrangement where the chain came off at the finish line where the pit crew could reinstall it quickly and efficiently. An odd arrangement to be sure but good enough for 48 laps and third place. Based on their performance when running right, with good battery management they could have done at least 72 laps; possibly contending for first. But it was Pete Robustellini, smoothly driving his orange four wheel car, that managed his batteries into first place with 77 laps. This just confirmed his position as the leading competitor in current DEVRA Racing! A worthy goal to aim for!

June DEVC Meeting: Saturday,6/13/09


Boulder ElectroRide, Inc.
 
Discussion points:
  1. What Li-ion chemistry is best now?  What cell size?  How does DEVC see the costs coming down (if at all)?
  2. BMS options.  Build or buy?  What features are essential and which ones are nice but not essential for a small pack.
  3. Controller options and regen braking.  Is the latter worth the effort?
  4. Marketing strategies.  How can we convince customers that paying more capital upfront for Li-ion is cost effective in the long run?  Is there a viable battery lease strategy for small players?

Conversions and what I have learned and what is the best way to get started featuring Zach Tyler. April 19 at 10 am.
'I never said I would do a DEVC meeting! Oh, I did? Well, I guess I have a couple of topics. Here are some possible titles: Starting a conversion business "How You Too Can Drive Youself Insane While Loosing Money and Friends", or "Why The Hell are You Interested In EV's When There Are Perfectly Good Internal Combustion Vehicles Out There Right Now!" or better yet, "Electric Cars, If you own one you'll be one of 50 people in the state still driving while the rest of society is tearing itself apart". All kidding aside I'll probably talk about conversions and what I have learned by doing them, and what I think the best way to go about one is. There will be more to see. Here is a link to the BMW I just finished. The address is 2546 South Main Street, Erie CO 80516 Unit B.'

5/22/07 at HybridsPlus
Members of the DEVC met Tuesday evening in Boulder for a tour of the HybridsPlus facility. Long time DEVC members and HybridsPlus owners Carl Lawrence and Davide Andrea were our hosts for the evening. We observed how the cells were welded and built into complete battery packs. During the presentation we were told that their next conversion to PHEV was scheduled to be a Ford Escape Hybrid. A highlight of the evening was attending DEVC members pitching in to actually help install the replacement battery pack in a Toyota Prius, followed by a test drive of the car to prove how well it worked. The amount of time needed to actually install the pack itself was perhaps 15 minutes. Of course all of the difficult work had already been performed by the HybridsPlus staff. The old pack had already been removed and all of the pre-assembly for the new pack and vehicle modifications had been completed.

3/17/07 at Long's Garden in Boulder. With the theme "Solar Power in Agriculture" we had a selection of presentations and displays. Thanks to Catherine Long's hosting the event we were provided with coffee and cookies and got a tour of her new photovoltaic power installation. It was installed last fall and provides a maximum output of 9.7 KW, powering the business and her home too. Gary Leever of Nameste Solar was our tour guide for the solar installation and the ancilliary equipment to convert the DC to AC for distribution and resale of surplus to Excel Energy. A number of members took a keen interest in the installation and there may be more installations in the future of some club members.

George Gless, the longtime member and newsletter editor, was kind enough to drive his GE Electric garden tractor over and to explain the details of its use and operation. George has had it for a number of years, having bought it from another member, Richard Schalhammer. George uses it to plow snow and garden as well as for mowing and other tasks. Several were surprised to find that it was electric!

In the same vein Tom Lopez of Longmont brought a range of electric garden equipment that he manufactures and sells. There was a solar charged, battery powered lawn mower; a small solar garden tiller; and a full sized tiller equipped with a "flip plow" that was demonstrated to an interested group. It showed a willingness to "Dig Right In!" and Ken Jones, a member with a strong agricultural background, took the tiller handles and put it to work. After cutting a furrow, turning the tiller and flipping the shares, and plowing back, he pronounced it satisfactory!

There was one new member added at this meeting; let us welcome Rick and Liwh Ferguson of Colorado Springs to our organisation. Also long time member Robert Bushnell was there as was Bob Patterson, a well known Scot and Glaswegian! Glad to see everyone; all sixteen members and visitors had a good time! Our next meeting is in the planning stages and will be announced shortly. There will be a DEVC sponsored event in Longmont at the FRCC campus where you are invited to bring and show your EV's. The highlight will be a DEVRA electric car race with registration and tech inspection starting at 11:00 and the race starting at 1:00, lasting for one hour!
