Well, it seems there is a lot of unknown on this subject. Thank you Hans for your interesting details, especially the graphs. In the meantime I found another interesting youtube video about a travel with many charging details with a 2022 EGO.
I already wrote 3 mails to energica about other things (one was also a request to change the speed control). They never responded. In the meantime I also have a button for the speed control on my left hand bar. I found this in another forum and my technician from my dealer made it happen.
If you could give me instructions Hans on how I could have the same datas you brought from your bike to your iphone, that would be great.
About battery behavior in general I found a very interesting digital book, written by David Bricknell (it is still available in Apple bookstore for free!) about the BMW i3, that we use now for 41/2 years. I place a screenshot of the battery envelope where you can see the optimum temp. is between 10° to 50° C. (or 50° to 120° F). I don't know, if you can simply transfer this values to the battery of an energica, but it gives a good idea, that they work in a wide range.
I asked my dealer to organize a graph, where one can see the envelope of the battery in our bikes. Also what parameters have an influence on determing the charging power in kW and when they kick in. When I got information on that I will post these.
