I was prepared to swear it blows the air out, but decided to go do a match test

How could I be so wrong?

[DonTom]

The fan is pulling air, pushing it past the charger and out the tail section of the bike. However due to the proximity of the fan to the heat-sink it my feel like some air is blowing up.

Looks like our  Energicas are not cooled like a computer.

"Should fans mounted on the top of the case suck air in or blow air out?
Because hot air rises, if you're building a computer that has additional fans on the top, those fans should blow hot air out of the case."

Thanks.

Did some recording during my last CCS charging. Since the charger also provided the delivered charge, I also recorded that. The range is taken from the dash and obviously will change depending on the ride style.
The conditions: 50km (31mi) on flat lands, no hills at all, max 100km/h (62mph), rather gentle acceleration. I left my race mode at home today . Battery symbol was green during charge and after finished. Dry autum weather, 19degC (66F).

What is the temperature when in the yellow?

[DonTom]

What is the temperature when in the yellow?

Blue   =less than 5°C  (41°F)
Green =6  to 40°C  (42.8 to 104°F) 
Yellow =41 to 55°C (105.8 to 131°F)
Red    =above 55°C (131°F)

That short trip must have been borderline already. As stated, the battery symbol was green after charge.
Did a 150km/93mi trip a few days earlier, just more aggressive ride style. Ambient temps were a bit warmer at around 22C/72F. The bike began throttling the charge already at 55%SOC and showed yellow after powering up. During the remaining 50km/31mi back home it stayed yellow. I missed to at least put my hands on the battery case to get an idea if I could have felt the heat.
I am missing the opportunity for a longer (>150km) trip & fast charge - plus repeat that at least 3x. This will give me some real day trip indication. Maybe use some temp sensors to get an idea about the temp increase during riding and charging. And even if equipped like that it might even show a delay until the induced charging heat really ‘surfaces’ on the batt case outside. Not sure if 30 or 40mins is already enough.
Don, thx for the temp/color ranges.

I see you are right about the fan. Went through the menu. Fan was set at 100%, but was running at 30%. I toggled to 30 then back  To 100 and now is runs at 100%.
That did not fix the low current draw issue, and the exhausted air is not warm.

How did you check the fan speed setting and adjust it? I have never seen that on the menu of my Ribelle?

Of note - the cell manufacturer, Farasis, specifies the following for temperature limits...

Discharge: -20C to 60C
Charge: 0C to 45C

It's the CCS charge conditions for the larger battery that are worrisome - if heat can't be dissipated cell longevity is compromised.

The 3-year battery warranty is now explained - I had high hopes for 10-year longevity but instead 5-years seems more realistic.

That's why the manual says always use AC charging when you have the choice. A charge of a few KW is unlikely to get above 45 C.  You don't want to exceed 45°C more often than necessary.

The problem is that fast DC charging is  often necessary when on a trip on a warm / hot day.  If they can squeeze a 6 KW AC charger in there, there will be more times I would try to use it during trips which would be a lot better for battery life than DC fast charging.

BTW, there are times where I find DC fast charging too fast. For an example, if I want to go to a restaurant while charging. Then I would go out of my way to find a J-plug near a restaurant.  But 3 KW is too slow. DC is too fast. 6KW is usually just right for a restaurant stop.

I usually charge my Zeros at 6KW. I am usually recharged to full about the same time I get back to the bike from a restaurant. There are many times that I prefer the 6KW charge to either a faster or slower charge.

Thank you Don for your continued input on this topic - I'm coming to realize it's up to the end-user to manage thermal conditions and the bike's safe-guards are to prevent run-away hazards not preserve operational integrity of the battery.

How did you check the fan speed setting and adjust it? I have never seen that on the menu of my Ribelle?

If it is the same as my 2020  SS9-, it is under "Preferences-Charge-Fan limit-80% (or whatever % you want).

My new Ribelle doesn't have that on its menu, under Preferences-Charging its just SOC amount

By any chance does it automatically change speed while charging (depending on charger temperature)?

Or is it always at the exact same speed?

But either way, I think it's probably somewhat of a useless setting anyway and I can see why they will remove it. I don't see any reason why we should have to control the fan speed to the charger.
