I am remiss on both blog and video these busy days. Richard Flentge has rejoined me at EVTV to try to get the backlog of parts orders out. But I’m still a little overwhelmed by the targets of opportunity that greet me each morning. Two steps forward and a step back. I was discouraged to […]

I’m busy as Santa in the EVTV shop vainly striving to tease clever out of not very good C++ code. Surrounded by too much equipment costing far too much to do so little. Fumbling with my blighted mind and recall, bereft of friend or assistant, and mired in an overwhelming sense of disorder and detail

After a month between videos, I find we have about 4 hours of video to hand. So I split it into two videos. I particularly wanted the Quaife install video as a single entity for future reference. Mr. Bill Bayer was a weatherman with the United States Air Force in Afghanistan. He became somewhat disillusioned

I’ve been working furiously this week on a 48v battery module and controller to work with the Sunny Island 6048 US Inverter. Coming nicely I think. This will be a good combo. But there is a kind of identity crisis between the Sunny Island and the grid-tied Sunny Boy. In Germany, where they are made,

Our news media once held promise to be the common campfire that bound us as a community to discuss the important issues of our time. It could have continued to evolve in that mission, but for various reasons has abandoned it in favor of entertaining us with inexpensive talking heads on the dubious assumption that

I’ve been obsessing on a new controller design for the Tesla Model S battery modules to such a degree the past two weeks that I’ve rather failed to do a video, or even blog our last one. Which is remarkable in that in the May 26 video, actually published on May 24, I’ve not only

Electric vehicle design has advanced rapidly in the eight years this month that we’ve been doing EVTV. Our first build used a forklift motor and a Chinese pulse-width modulated controller. Today, OEMs almost universally use 3 phase AC motors that are liquid cooled and use an advanced Field Oriented Control algorithm to control torque and

EVTV celebrates eight years of publication this month. Our first video was published May 22, 2009 and we have just uploaded video number 312 – two hours, nineteen minutes, 50 seconds. When we began this journey, there were ZERO electric cars available for purchase anywhere in the world – Tesla Roadster being much talked about

The Tesla Drive Unit continues to shock and awe – at least us in the shop. And of course, no sooner had we posted the last video than our “Jack Rickard wannabes” sprang to action to note METOO so it is genuinely an area of interest. We did learn a bit in dismantling the drive

The heart of the issue of electric automobiles has always been the energy storage cell or battery and it remains ever so today and into the future. Moving from the crude lead acid batteries, the limitation on electric cars has always been the weight and size of the battery necessary to power it to any
