Below are those updates, as I will be removing that doc.<br />

I (Wei-Ren) have been busy with Jarod to fix more last minute problems but in the end we did manage to get all the electrical issues fixed and Mallory running smoothly. We finished in the end with 3149 miles per gallon (unofficial)!!! <p /> Unfortunately, we cannot qualify as our car was also about 200 lbs more that the require weight limit because we overbuilt our car. If we were able to qualify we would be thousands of miles more mi/gal than the other urban challenge cars and 2nd overall to Purdue's vehicle. :( to that but we have certainly learned a lot for next year's car. Also unfortunate we didn't have members from last year to help us improve our car this year but fortunately we used double side duct tape to mount our Ga-As cells so we can reuse them for next year's urban challenge. We'll be getting some competition from Purdue in the urban concept next year and I am super excited if we were to come back next year with the same team to kick some butt.<p /> Here is a recap of what happened at Shell Ecomarthon Houston 2010.<br />Thursday:<br />1. We found that our blocking diodes were wired backwards which was huge error on my (WR) part. Jarod and I fixed it and finish wiring up the array to the maximum power point trackers (MPPT). We also tried programing the remaining MPPTs we needed for the array. The Biel's MPPTs were a pain and we should get them fixed or replaced if we were to focus on the Shell Eco.<p /> 2. Friday <br />The course was opened for practice runs and I (WR) got out on the track with the batteries to get a few of the road and get a feel for the timing for the speed needed to get 10 laps and 3 10 seconds stops in 26 minutes.<br /> At night, we finally manage to successfully reprogram 4 MPPTs out of the 8 we had. These MPPTs seriously need to be replaced or refurbished. It took way way too long to get that done and anyways they aren't all that efficient at the low voltage we were running Mallory at.<p /> 3. Saturday <br />We had a few good runs on the course, and had a better feel with the driving strategy. After the first heat, we tried tweaking the motor a little more and ran down the battery a little more from the full pack that we started. The next heat, we unfortunately drained our battery pack down to NIL as the weather was horrible so at night before we left charging up the batteries overnight.<br /> Also, I popped the steering out from the steering rack and was fixed later by Sean.<p />4. Sunday<br />In the morning, the packs were only charged up 30% and was not sufficient during heat #4. The BPS shut us of as I tried limping back into the pits. We switched out our battery pack with our spare battery cells and were able to get up into heat #5 and heat #6. The weather was perfect for solar racing and we manage to pull of 3149 miles/ gallon (unofficial). Unfortunately, we can't qualify due to our weight.<p /> Well that's a recap of what has happened. I'll update later with pictures and more notes. <p style="font-size: 10px;"> <a href="http://posterous.com">Posted via email</a> from <a href="http://solarcar.posterous.com/shell-eco-race-updates">solarcar's posterous</a> </p> </div>Teamhttp://www.blogger.com/profile/08360018860998052582noreply@blogger.com0tag:blogger.com,1999:blog-1082762626173631686.post-53450902260480353882010-03-28T15:43:00.001-07:002010-03-28T15:43:37.103-07:003,149 MPG!<div class='posterous_autopost'><span style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Times New Roman; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-indent: 0px; font-size: medium;"><span style="color: rgb(128, 128, 128); font-family: lucida grande,tahoma,verdana,arial,sans-serif; font-size: 11px; text-align: left;"><h3 class="GenericStory_Message" style="margin: 0px; padding: 0px; overflow: hidden; font-size: 13px ! important; color: rgb(51, 51, 51); font-weight: normal;"> The team managed to get 3149 miles per gallon with the (not so) svelte Mallory. <br /></h3></span></span> <p style="font-size: 10px;"> <a href="http://posterous.com">Posted via email</a> from <a href="http://solarcar.posterous.com/3149-mpg">solarcar's posterous</a> </p> </div>Teamhttp://www.blogger.com/profile/08360018860998052582noreply@blogger.com0tag:blogger.com,1999:blog-1082762626173631686.post-63331568371283578592010-03-26T22:38:00.001-07:002010-03-26T22:38:52.901-07:00Untitled<div class='posterous_autopost'>Day 2 was some what successful. We managed to pass all our tech inspections which were a breeze compared to the North American Solar Challenge. The only thing that we failed to do was to be under the required weight limit of 350lb. Our chassis was definitely overbuilt for this competition. The Elecs had their own fair share of issues. We had problems programming 5 of the 9 maximum power point trackers. Jared and I spent the whole evening till midnight getting 4 MPPTs reprogram. The elecs are done done done at this point. It's unfortunate that we are so over weight. <p style="font-size: 10px;"> <a href="http://posterous.com">Posted via email</a> from <a href="http://solarcar.posterous.com/14628718">solarcar's posterous</a> </p> </div>Teamhttp://www.blogger.com/profile/08360018860998052582noreply@blogger.com0tag:blogger.com,1999:blog-1082762626173631686.post-9105736692673578662010-03-26T12:59:00.001-07:002010-03-26T12:59:24.301-07:00After a late night fixing problems we are all set to go on the track.<div class='posterous_autopost'> <p style="font-size: 10px;"> <a href="http://posterous.com">Posted via SMS</a> from <a href="http://solarcar.posterous.com/after-a-late-night-fixing-problems-we-are-all">solarcar's posterous</a> </p> </div>Teamhttp://www.blogger.com/profile/08360018860998052582noreply@blogger.com0tag:blogger.com,1999:blog-1082762626173631686.post-47150056698271773902010-03-25T10:46:00.001-07:002010-03-25T10:46:08.795-07:00we're in houston now!

We arrived an hour earlier to look around the zoo. <br />Tucson is definitely missing a zoo.<br /><br />The food was sponsored by SolarWorld which were the Germany's main sponsor which consisted of salad, burgers, corn and dessert.<br /><br />It was a deja vu moment for me as it reminded of NASC 2005. I was happy that we were able to have such a reliable car both mechanically and electrically for a 3 year old car.<br /><br />The first awards that were handed out were the observer awards which were traditionally handed out. We of course received the "Cinderella Watch Award" for being late at the check points. This was due to our very aggressive approach in trying to push our car to it's very limit. Anyways we still beat the other 2 Wildcats in the race.<br /><br />It's 9 pm now, we just cleaned out all the support vehicles and packed the trailer for our long trip back to Tucson....Teamhttp://www.blogger.com/profile/08360018860998052582noreply@blogger.com2tag:blogger.com,1999:blog-1082762626173631686.post-52060671192005612472008-07-23T08:16:00.005-07:002008-07-23T16:36:55.175-07:00Final DayThe night before leaving Medicine Hat, we double checked our official times and there was a huge error with our trailering penalty. This error was significant as the new corrected overall time put us about 3.5 hours in front of U of Kentucky, our closest competitor. We got this corrected Tuesday morning.<br /><br />We started with a 40% full battery pack on Tuesday morning because we had pushed the car close to its max. Arshed and I had accounted for good clear weather before the race started at 9 so we could as least get a 65-75% state of charge (SOC) in our battery pack.<br />Unfortunately, the weather turned out opposite to what Arshed and I, with 8 days of weather forecasting experience, expected.<br /><br />Nevertheless, we left at 9.30 am and crawled towards Calgary where the sun was better. We stopped about 10.30 am and charged back up to 55% SOC and continued on. We kept crawling towards the finish line.<br /><br />The weather was splotchy towards Calgary which drained our batteries down to where we had to stop. We had 100 miles to go at that point. It was 1 pm and we had 3.5 hours till the finish line closes. We decided to trailer so we could at least cross the finish line with our car.<br /><br />Alas, we did not make the finish line with our car. We were very disappointed to not able to get a picture perfect finish. Traffic conditions and the truck running out of gas at the last minute were a few of the things that prevented us from reaching the finishing line on time.<br /><br />That night, we saw some of the Kentucky guys and asked them whether they made it all the way on their own power. They said that they had to trailer from 30 miles out of Calgary. At that point, Arshed and I knew that we had beaten them.<br /><br />Here's the official final standings.<br /><br /><br />1 2 University of Michigan 51:41:53<br />2 32 Principia College 61:38:45<br />3 1 FH Bochum Solar Car Team 63:47:55<br />4 24 University of Waterloo 64:00:06<br />5 35 University of Minnesota 65:41:48<br />6 65 University of Calgary 75:42:53<br />7 42 Missouri University of Science and Technology 81:20:36<br />8 9 Iowa State University 91:12:59<br />9 95 Red River College 92:15:02<br />10 8 University of Arizona 98:26:12<br />11 3 University of Kentucky 100:33:24<br />12 100 Queen's University 106:36:20<br />13 11 Northwestern University 113:58:11<br />14 175 Durham University 134:07:06<br />14 256 Oregon State University 145:20:00<br /><br />We're still the #1 WILDCAT!Teamhttp://www.blogger.com/profile/08360018860998052582noreply@blogger.com2tag:blogger.com,1999:blog-1082762626173631686.post-57725795084185673962008-07-22T00:09:00.003-07:002008-07-22T00:43:12.772-07:00Final (fatalistic?) Approach...As our competition approaches its exciting conclusion, I thought I'd offer a synopsis of recent events to give an idea of what our situation is at present.<br /><br />The team ran into some difficulty during the leg from Fargo, ND to Winnipeg, Manitoba, Canada. We had just had a hilly leg that took us from Sioux Falls, SD to Fargo. Due to terrain and inclement weather, we arrived with a somewhat depleted battery pack. The situation was exacerbated by the fact that Fargo was overcast as well. As a result, we trailered into Winnipeg, Manitoba, Canada, and subsequently proceeded to Brandon (the next checkpoint). We drove the whole distance from Brandon to Regina, Saskatchewan, arriving at the latter early this morning. This was followed by the penultimate race leg, a 300-mile marathon from Regina to Medicine Hat, Alberta. This leg's intent seems to have been to separate the wheat from the chaff. A number of teams trailered it, but we decided to take advantage of the ideal conditions and run hard and fast. SK is the North American version of the Outback, allegedly. One major difference is that is far more hospitable (as indicated by the deer we saw). The rolling, verdant hills reminded me of the rolling hills we'd seen through Kansas (while most of that state is notoriously flat plains terrain, the NASC route went through the hilly portion). As long as we had the sun to our back, we were cruising. However, after a while, the sun's angle shifted to the front, weak part of our array, and our battery pack began to deplete more readily. After two or so roadside charging cycles, we ran out of time about 25 miles outside of Medicine Hat. Nonetheless, our efforts should put us well ahead of our nearest rivals, once the numbers are properly tabulated.<br /><br />Despite a somewhat outdated vehicle design, limited experience, and anemic battery pack, we've been able to make it all the way to Alberta. It's on to Calgary, tomorrow!<br /><br />Sleepily,<br />Arshed<br /><br />PS Don't forget to examine the slew of images we've been accumulating, below.

What was really killing us was not having some sort of balancing circuit and no cruse control.<br /><br />Arshed was back in the seat this morning after I made it clear that I wanted him to drive this morning.

We had to trailer our car from Fargo, ND to Winnipeg yesterday. Today, we had to trailer from Winnipeg to Brandon as the whether didn't hold up for us and this is the longest leg of the race from Winnipeg to Medicine Hat. Tomorrow, we have about 370 miles to cover in 10 hours.<br /><br />Arshed and I have been sitting in the third row of seats in the suburban working on strategy. We have very very little leg room and in the future a 15 passenger van would have been better leg room or better yet a custom cargo van for telemetry and strategy.<br /><br />I jokingly suggested that we should have one of those Matrix operator rigs where we can see the numbers rolling from left to right instead of from the top to bottom. <br /><br />As the strategists, we have been doing better than I expected. With no experience or previous instructions to go off, we were able to make some crucial decision. Arshed mainly works on our spreadsheet SOC predicted calculations, elevation and weather, while I work on making sure that our batteries are in check and speed control. Together we discuss different options for the current condition of the race. Arshed has been very valuable to the team.<br /><br />The car is functioning pretty consistent with a 3 year old car with an old solar array and battery pack. We have had no problems since the first day of mishaps, otherwise we would have been right with Red River College and Iowa, smoking Kentucky instead of catching up with them.Teamhttp://www.blogger.com/profile/08360018860998052582noreply@blogger.com2tag:blogger.com,1999:blog-1082762626173631686.post-4213279503540574112008-07-18T00:08:00.003-07:002008-07-18T06:53:13.268-07:00Falling into place in Sioux Falls...We apologize for the radio silence for the last few days. It's been pretty busy, and pushing forward consumes most of our efforts, to say nothing of the fact that most of us have long since lost track of time and place (in regards day of the week and what state we're in!).<br /><br />In regards to our performance of late, we are slowly increasing our performance as we get a better sense of how the vehicle performs in different settings and how hard we can push it. We can gauge our relative performance from day-to-day better now, which has helped us take risks and drive more confidently.<br /><br />Currently, we are fluctuating in 10th-11th place for total elapsed time. This includes our initial mechanical troubles, as well as navigational missteps and inclement weather. Indeed, this last point has given us some trouble, as we have to be very wary of not running our batteries down too low. Nonetheless, we have been able to pass a few teams. There's a bit of schadenfreude involved when we manage to slowly overtake a similarly slow-moving vehicle on a rainy day...<br /><br />All in all, we continue jockeying towards the lower-middle of the pack. Given our concerns about this venture being remotely viable at all, we're quite happy about our performance thus far.

Tomorrow we will go all out and try to be ahead in the lower pack of the race.<br />As we entered the check point in Tulsa, OK, we saw Queen's leaving and also heard that Red River College left right before Queen's.<br /><br />The lower pack (in my own opinion) consists of Queen's, Red River College, Iowa State, U of Kentucky and US.<br />We would have been closer to them if we did not today's last minute issues.<br /><br />1. we had a flat on the startig line<br />2. we had to do a driver change because the driver was not comfortable<br />3. when we wanted to change drivers, the driver ballast were all left in the trailler.<br /><br />These driver mistakes could have been avoided. The leads have decided that all of them will be accountable if one of them makes a mistake.Teamhttp://www.blogger.com/profile/08360018860998052582noreply@blogger.com2
