Nice those chargers with graphs. We don't have those here in Belgium. I can plot graphs from BLE data though ??.

It would be useful in your case to know battery temp. Not just the color of the icon cause that only turns red at 40 dC. That's also possible from my apps or just the ble data.

I say this cause it's perfectly possible to ride like high speed or highway and heat up battery to 30 dC or so causing the bike to throttle soon after starting a charge. For example below graph is after highway first charge.



For myself on 2021 SS9+ the first charge I can often keep it above 20 kW if I don't charge for more than 20 minutes or 50% of capacity. I typically aim at 30-80% charges. Starting below 30% will also always throttle before reaching 80%.

This was probably the last video I made on charging temp, got more on my channel

And in comparison this is a better charge curve started at 75A or 24 kW where battery wasnt that warm to begin with



I think I need another video on this subject 😂

Very curious myself if Experia performs any better. They did claim am improved battery cooling design...

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.

@jotjotde: Thanx for the hint. I drive around in the Bad Säckingen-Schwarzwald-Laufenburg area and there are some EnBw charger. So I will try to make a picture of that. Where are you driving?

Hi, I am located in Warendorf/NRW. These chargers displaying the curve are standing exclusively at Shell Fuel Stations.

The charging of the EsseEsse with 24 kW up to 80 % as you described sound quite unusual to me. That should be possible only under near perfect conditions because the battery heats up during CCS charging. Above 20 °C ambient I usually end up with a yellow battery symbol after every CCS use and that means a significant reduction in charge power.

Another point of view maybe:
Forget about the kW numbers and look to the charging time. How long did it take to go from about 10 % to 80 %? In my view this is much more important, at least to me, because it's the time I cannot enjoy driving  .
That time should be about 40-45 min acc. to my experience. If that is the case then your bike should be OK and just displaying false numbers (which, by the way, wouldn't be unusual for Energica - we all know the speed is shown 10 %  and the temperature 4 °C too high).

Hi jotjotde: You mention an interesting point: The temp. displaxed is at least 4° too high. If this temp. is used to determine the max charging power, one might be easy in the yellow range, that might reduce the power. I hope to get details from my technician on that. I expereience the same chaerging time as you do, and this is also to me lost time to enjoy riding that beast...

Hi!
So if you are seeing the same charging times as others, the displayed kW numbers shouldn't matter too much, should they?

As discussed these numbers might differ due to several reasons, maybe even from bike to bike, but in the end what matters (at least to me) is the result, i.e. the charging time.
Looking at the charge curves of Hans, there is a difference of merely 6 minutes between cold and warm charging. I can live with that 

BTW: The temperature on the display is ambient, not battery (it is changing quite quickly e.g. when you enter a shady wood on a sunny day). I doubt that ambient temperature is influencing the charge performance. Why there is this 4 °C difference to real temperature I cannot say, for Energica it would be easy to fix, but so would be the speed difference .

Okay guys, thank you for all your answers! I learned a lot. And as soon as I have news from Energica, I'll post that here.

Cheers!
