These were the days my friend….. This week we acknowledge a sea change and weather change in the land of Electric Vehicles. It will take some years yet to play out, but the helm has swung hard over and we are no longer destined to fall off the edge of the earth into that dreaded […]
I suppose it is time to face reality. We have won the battle most completely. And we have lost the war most entirely. I concede defeat reluctantly, petulantly and never with good grace. But it is time to finally admit, I was wrong about the Battery Management Systems and/or Battery Monitoring System issue. And I’m

If you’re not living on the edge, you’re taking up too much room. Or so I’ve been told. This week’s show is almost entirely devoted to watching paint dry. But it’s fast dry paint. We attempted to charge a CA40FI series cell at a 3C 120 ampere rate. The Chinese manufacturers of the Thundersky, Sky

As many of you may have picked up, I’m not really by standard definition a “car guy”. I don’t really like cars. I don’t even like to drive. When we go out, my wife normally drives. Strange thing I wind up doing given that context. But I am a battery guy. I’ve always been fascinated

Tell me if I”m correct. And tell me if I’m not. I rather see the future of EVTV as moving somewhat away from our various builds, though we undoubtedly will always have some project going. And more toward viewer contributed videos of their builds. This video kind of qualifies. We have Richard Rodriguez with a

It’s cold here in Cape Girardeau for July. Actually, not. It has been over 100 degrees Fahrenheit every day and most of our shop is devoid of air conditioning, making EVTV a pretty miserable place to be, much less pinned to for two hours writing down battery measurements every minute on the minute. But we

This week we begin testing the new CALB gray cell, the CA180FI. As I mentioned in the last post, these new cells sport some interesting improvements. The most minor, and most welcome, is they are labeled with a serial number and a tested Ah capacity. The cells are manufactured on a newer, much larger production line

I was able to post this week’s video ON Friday. We shot a good bit of it last week. So this week we do a 4C load test of four CALB 100AH cells. The test actually consists of 40 pulses of 400AMPS lasting 2.5AH or about 30 seconds. The CALB cells list 4C for 30

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

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.
