I think I read somewhere in this forum there's a small risk of blowing a fuse when charging at 80 amps, maybe I should limit it until I get the update.

Is that fuse in the battery pack or somehwere esle that is almost impossible to replace?

It's the DC charging fuse inside the battery pack.

DonTom,

At 12% SOC the Eva is at about 291 volts. At 99% SOC it is at 332 volts. Don't have any photos of starting to charge at a lower SOC but guessing it is 280 something down at 5% SOC or lower.

Assume 280-333vdc

Yesterday after work I decided to charge on 110 volts instead of 220. Here are a few details:

I plugged in at 5pm.

5pm: 50% SOC, charging at 1kw/6A, 9:59 remaining till 100%
8pm: 60% SOC, charging at 1kw/6A, 9:43 remaining till 100%
9pm: 64% SOC, charging at 1kw/6A, 8:38 remaining till 100%
4am:90% SOC, charging at 1kw/6A, 1:37 remaining till 100%
5am: 94% SOC, charging at 1kw/6A, 0:48 remaining till 100%
6am: 97% SOC, charging at 1kw/6A, balancing
6:30am: 99% SOC, charging at 1kw/6A balancing

It took 3 hours to increase the SOC by 10%
It took 12 hours to increase the SOC by 44%
On my previous Eva107 it could charge from 0-100% in 9 hours.

The chargers are the same size and the Ribelle has a larger battery than the Eva 107 has. But the charge times are far slower than the charger size/battery size would indicate that they would be.

This afternoon I did another CCS charging with my Ribelle. Here is what the charging curve looks like.

I started charging at 21% SOC.

21%- 72A, 21kw 25 minutes to 80%
37% is when charging began to taper- 67A, 20kw
44%- 58A, 17kw
54%- 49A, 15kw
61%-47A, 14kw
70%- 45A, 14kw

Total charge time to 80% was 35 minutes. Similar to last weekend, total time was 10 minutes longer than claimed when first plugged in.
Air temperature at charging was 72 degrees. In the hours prior to charging my Ribelle was at the dealer. Distance from dealer to charger was 4 miles. The battery was definitely not warm at the start of charging.

When I finished charging the battery icon was yellow and stayed that way for the 64 mile trip home. 30 minutes after arriving home the battery icon was still yellow. Air temp at home was 71 degrees.

Last weekend I added 11.6kWh at an EVgo charger for $13.51
The Electrify America station I charged today at added 9kWH for $3.87

I arrived home with 12% SOC and at 7pm I plugged my Ribelle into my 110 volt charger. If my calculations are correct it should finish charging around 5pm tomorrow afternoon.

What is yellow?  As best as i can tell it spans 40C to 55C and that's allot - be nice if core temperature was digitally displayed...cannot blame Energica however for development steps taken to increase range and trade offs that result - for my application CCS charge won't be a big dependency but then global warming seems real.  BTW - chilling down the pack during CCS is the only option to stay out of yellow...think sweaty contact surface kangaroo pouch thingy  w/ flap...stop at McDonalds and get a 32oz cup of ice and 8oz of water...amazing cooling potential and stows away efficiently.

That sounds neat!  I wonder how you'd spread the heat so there's no spots with too much temperature difference.

PWM, It was rare for my Eva 107 to heat the battery up to the level of the yellow icon even when doing multiple CCS charges in a single day. On times when it did it quickly cooled down to green once riding again. There was only one time that it didn't do that, temps were in the 90's and after the 3rd CCS charge the icon stayed yellow the entire time for the 55 mile ride home. There are obviously many differences in the battery packs of the Eva 107 and the Eva Ribelle. But the Eva 107's battery has far better heat management than the Riblelle's battery does. But I really wonder if the Ribelle's temperature sensor in the battery is accurate. When I had my Zero SR the motor temperature always seemed to read almost 10 degrees warmer than ambient. And this was when Zero had a problem with the motors getting hot and I think it had more to do with faulty sensor than it did with motor design.

After using CCS a few more times since getting my Ribelle, I can confirm that all it takes is one CCS charge (high teens/low 20’s to 80%) to get the battery temp indicator to go yellow. With the temps here in the inland SF Bay Area staying in the 80s and 90s, it stays yellow the rest of my rides.

I haven’t had it go red and I haven’t done more than one CCS charge in a day but it definitely appears to be a difference in heat management between the 21kw batteries and the 13kw battery on my EsseEsse9.

My EsseEsse9 has been able to take two CCS charges in the same day before going yellow and seems to cool down quicker than my Ribelle given enough cool air flow although the number of cool days has been few this summer.

I’ll play around with CCS charging and long rides more once fall weather kicks in and the riding temps drop into the low to mid 70’s to see how the 21kw battery performs compared to the 13kw.

The above being said, after getting used to the range limits on the EsseEsse9, I have zero range anxiety with my Ribelle. Definitely glad I picked up the bigger battery bike despite the potential thermal management concerns. Not to mention the more I ride the two bikes back to back, the more impressed I am with the power difference between the two bikes.

For Ribelle coin represented I will ask Energica if they can swap a 13.4k battery as an option to take delivery...I'm that concerned.

Will the Ribelle w/ windshield go 80% capacity, at what steady-state speed, at what given ambient condition w/o going yellow? 

Hate constraints on riding so need to do something...

What is that CHILL-EXCHANGER all about?

I doubt you’ll be able to get a Ribelle with the 13kw battery, you’ll probably have to look into an older EVA 107 if you want the 13kw battery.

All of our notes about battery temps and charge speeds hasn’t stopped me from doing 2-3 hour rides on my Ribelle and doing CCS charges as needed. For me, it’s merely an observation of the differences in behavior between my 13kw and 21kw bikes.

Overall, I have no regrets about adding the 21kw bike and I definitely ride it hard on most of my backroad rides. I like no longer giving range a second thought like I do on my 13kw bike.

Granted I haven’t done any long distance rides on my Ribelle but that’s mainly because my back doesn’t like the more aggressive riding position for more than an hour or so at a time. But for backroad aggressive riding, it’s the one I go to every time over my EsseEsse9.

It would be interesting to hear from EsseEsse9+ owners since I imagine they would be more likely to do long distance riding/touring with the more comfortable riding position.

I have already asked the question in reverse, can my 13.4KWH  battery  be replaced with the 21.5KWH battery. There are other differences, even in the same model, between the two battery sizes. Many cables would have to be changed and it would probably be more expensive for that to be done than to upgrade to the bike with the larger battery.

So the reverse must be as true.  IOW, you're stuck with whatever battery size the bike came with.

Agreed. One of my frequent commutes, PDX to Corvallis, requires bigger battery and the 3-5hr typical campus visit fits the Ribelle perfectly for back road travel and modest charge time demand to make it back home.  It is what it is...thoughts of swapping to a 13.4 pack is just expressing frustration...
