That's an interesting article Rob
I agree, lots of interesting information. A few points.
1, EV Batteries only charge to 80% and don't go below 30%. Does this mean firstly that the EV battery is only using 50% of the available storage and therefore twice as big as it could be if it used 100%, also as the battery degrades the battery management system firstly allows the top to be used until 80% is reached and then starts to allow the bottom 30% to be used meaning the user doesn't notice the battery has degraded as the range stays the same for longer. (although based on battery cost the life is very important so I would rather use 30 to 80 if that works). Secondly does it mean if I charged my phone once it got close to 30% and took it off at about 80% my phone battery would last a lot longer. Something I would be interested in doing with my electric battery power tools as the replacement batteries are more than the drills, saws etc. are. Also I wonder how much of the extra life is due to the battery really lasting longer and how much is just user experience based on only half the battery capacity used from the start.
2. Don't operate above 30 degrees is going to be hard when it reached 43 degrees in the shade yesterday. I guess people can go to work early in the morning and wait until after 9pm to come home once it cools down a bit and keep their bosses very happy.working over 12 hours a day. However is it OK to be above 30 degrees when not operating? Assuming I did drive the car below 30 degrees but then left it in a sunny car park all day what effect does that have on battery life, maybe parking in the much more expensive multistory car park in the shade would be worth the expense if the battery life is extended. No mention of extremely low temperatures being an issue so I assume that is OK?
3. I wish I could extract my body fat and run a car on that. Certainly looks like a winner if anyone could invent a car to run on body fat and a way for excess ft to be extracted.
