Went on quite a drive today. Everyone is concerned about the range of electric cars and fear it will be insufficient. At least when test driving, it is MORE than sufficient. It was again unseasonably warm, and two hours in the seat was a bit more than I had sought to enjoy. I drove the […]

This week is a fairly short show. We mostly feature Duane Ball’s Electric Beck Spyder 550 build. Built by Scott Smith in New York state, this car features many of the components in our own Speedster Part Duh prototype. It is an excellent example of craftmanship in an EV build.

Kind of a late blog entry. Busy week with Rickard Electric Speedster design. The May 28th show rounded up a lot of little parts such as the accelerator – with a little valet function box I refer to as “daughter mode.” [jwplayer file=”news052810-1280 – iPhone.mov” hd.file=”news052810-1280.mov” image=”http://media.ev-tv.me/news052810.jpg” streamer=”rtmp://s3jgrp4mv5fnqx.cloudfront.net/cfx/st” provider=”rtmp” html5_file=”http://media.ev-tv.me/news052810 – iPhone.mov” download_file=”http://media.ev-tv.me/news052810-1280.mov”] The basic

My experience with online forums goes back to the early 1980s, and indeed I wrote one of the very few 8080 assembly language software programs to manage large numbers of Usenet Newsgroups – PIMP. But the experience has always been mixed. The written word in the forums or newsgroups leaves many more able than others,

We’ve made some recent progress on the Speedster Part Duh, and rather gotten ahead of ourselves on the video thing. We were trying some things, they came together, and we’re not too much wanting to remove them at this point. So in this video we kind of do a walkaround to show the week’s progress.

I’ve posted the April 23rd Friday Show. We had a lot of wind noise I had to filter out so forgive Brain and I in the opening segments. We hadn’t been breathing helium or anything, I just had to lose the low frequencies to make the wind more or less go away. We’re still learning

This week we digress a bit from vehicle issues and take a look at the progression of LiFePo4 cell offerings over the past two years. We also do some full 1C discharge and charge tests on the cells. The first cell in this series is a Thundersky TS-LFP160AH cell we purchased about 18 months ago.

We were recently featured in a story in our local paper, the Southeast Missourian. Nice story. Thank you guys. We’ve been in quite a struggle with our MES-DEA 200-250 Motor. On assembly, we found a vibration in the drive train. When we removed the drivetrain from the vehicle, we found a huge crack almost all

We have finally made some progress on the 2009 Mini Cooper Clubman drive train. I had nearly given up all hope. My history is of course in electronics and software. Mechanical issues usually result in the use of a hammer at some point from frustration. This one almost brought out the big sledge. We originally

I’ve heard a lot the last couple of weeks regarding our top balance/bottom balance situation. Most of the online forum engineers did NOT skip a beat. They went off of current shunt balancers pretty much cold turkey, but immediately lunged to monitoring individual cell voltages for a “low voltage limit” as the holy grail of
