HI everyone,

How can we stop charging an Energica at 85% ?

I'm using 60% a day, and want to increase my battery life.
So my aim is to charge up to 85% and came back home with 25%

I set 85% on the app and hit the "SET" button without any result whatever the status of EVA... On / Off / On while charging / Off while charging... 
Even with the smallest 6A current (1,3kW), I get to 100% in 5h... and I don't want to get up at 4 AM to unplug the Eva ^^

Does anyone knows how to manage to do that?

Hi Anubis-R, It cannot be done (yet). The percentage setting on the app is the charge current, not the target SOC. The charge current can also be set on the bike now (updated since some months). I asked Energica the same question, because what you say, battery life, fan noise, power prices etc can all be reasons to automatically stop charging at a certain SOC.

[Anubis-R]

MMMhhh...

Well... if that really do impact the charge current, it should charge in 10h instead of 5 by setting it to 50%

But even by putting it to 45% yesterday, it continues to charge at 1,3kW and still shows "5h to reach 100%"

do you use this feature to reduce the charge current and affect the charging time then?

[SBK74]

We have another issue here I charge at home (Europe) with a single phase 230V outlet, resulting in 3kW at 13 amps. If I would dial to 45% it would result in 1,3 kW. I do use the charge control feature (on the bike then) a lot to reduce current, because below 2kW the fan does not come on that loud. Neighbours did not complain yet, but one mentioned the fan made some noise.

I am still waiting for someone to tell us that their battery has noticeably degraded due to its number of years in service or number of charges. There has been a lot of concern lately about how to extend battery life, but is this a real problem or are we just being "worry warts"? 

I have always kept my battery pack fully charged to 100% at all times on all of the Zeros that I have owned, and I have yet to experience any obvious issues. While my 2014 S did suddenly stop charging to 100% and started to stop charging at 92% after 3 years in service, I don't know if that is because of some issue with the charger, or a bad battery cell that is charging faster than the other cells and causing the voltage to spike in the pack, shutting off the charger, or some other issue. However if you leave the charger plugged in long enough it will eventually reach a 100% charge.

My 2012 Zero never showed a hint of battery degradation, up until the day that Zero grabbed it back a couple of months ago.

So am I I'm from france and happy to have a home charger wich let me chose 6 Amp on the charger itself, resulting in a 1,3kW directly and the fan is never turned on
it begins to be turned on while putting a 8 Amp charge from the charger.

however, i would be interested in having a 0,6kW charge to get the bike at 85% or so in the morning...

As we say in france "Better warning than curing"
I prefer to avoid 0% and 100% to get the best from my battery
maybe it'll allow me to change it in 8 years instead of 5... Who knows?
especially because energica have less feedback than zero regarding battery life, i prefer to take care of it as much as i can

As far as I remember, Zero Motorcycles took larger margins whithin their BMS (Battery Management System) than Energica does, which is possible because Zero have a lighter vehicule so they can accept a 10% increase of the battery pack.

Some studies did demonstrate that even 10% less charge can result in twice the battery life, which is not a small difference regarding the price of batteries.

[Richard230]

That is a good point about the Energica batteries. Especially, as they use a different battery chemistry than does Zero. They also advertise a lower number of charges that their batteries are rated for, compared with Zero. I think Energica says 1200 full charge/discharge cycles, compared with Zero's advertised 3000 cycles. Plus, the Energica is a much larger investment than most Zero models. I can see how you wouldn't want to push the envelope if your didn't need to. Plus why take any chances, since Energica hasn't been on the consumer market all that long and no one has any long-term experience with their batteries' actual service life.

If you are charging by plugging into a standard outlet there are many options:
1)  you can buy a simple mechanical plug timer and set it to stay on for some amount of time, you just need to get back and switch it off before it turns on again 24 hours later.  Something like this would work in North america : http://a.co/d/6vm9F67 its only $9 (Amazon also sells air of similar ones for $11) This one is also neat, it is just a simple "leave it on for 30 minutes, 3 hours or 6 hours" thing http://a.co/d/23LHyUY
2) you can get a digital plug timer, I believe this one has a "leave on for X amount of time, then turn off forever" mode:    http://a.co/d/520biFJ
3) you can get a wifi enabled plug that probably has some ability to set timers or whatever through an App or something, this one is only $10: http://a.co/d/2wJYP0l (there are lots of options, most come in multiple packs, so I just selected the first one I found as a single outlet example) I have no idea if the compatible apps actually have the ability to turn the plug off after a certain amount of time (or possibly energy) but I believe that is a pretty basic function that would be implemented..

To get your bike to actually stop at a certain SOC, it would obviously need to know the SOC.  I believe the J1772 protocol does transmit the SOC of the vehicle, so maybe there are J-stations that you can set to turn off at a certain SOC, I would bet that the Juice-Box would have that function if it exists.   Alternatively you would need to either connect to your vehicle CAN bus, or possibly use a camera pointed at the dash to actually read the SOC to do something based on SOC, and that just seems like more work than it is worth.

Oops, thought you were US   You can regulate the charge current on the bike from 1 to 15 amp (or 70 amp when fast charge), with the mode switch and key in the ignition.

[Anubis-R]

Thanks for your answers

I'll use a mix of both solutions for the moment... until energica decides to add an option to limit the SoC during charging 

limit the current throught the mode switch do work, and I'll use a timer to stop charging after defined time

I mostly don’t like mixing different vendor discussions in the same thread. Collating information from forum discussions is hard enough for me and readers of the wiki without topic shifting complicating things.

That said, I believe that Energica is using the same cell chemistry as Zero, just stacked “tall” not “wide” to get more DC voltage and work at lower currents. Let’s call this hypothesis: “112s1p”.

I’m also inclined to classify most battery degradation discussions here as “worry wort” class.

BUT batteries can degrade. I think so far those have been manufacturing defects and the more typical letting the battery sit unattended too long, but I’m just generalizing from some specific outcomes and there may be unidentified paths to degradation.

You can activate the LPR mode. The LPR mode will charge the bike up to 87%. Remember to clear it to ride the bike again.

ZeroG> You can activate the LPR mode. The LPR mode will charge the bike up to 87%. Remember to clear it to ride the bike again.

"LPR: this refers to the automatic battery maintenance device during the winter period or long periods of rest.

"All Energica models are equipped with the LPR (Long Period Rest).

"This feature allows the maintenance and automatic battery balancing for a long period of time. The LPR keeps the battery in the optimum state of charge in order to preserve and extend the life of the battery pack just by leaving the motorcycle connected to a power outlet."

https://www.energicamotorusa.com/what-need-know-electric-motorcycles/

Yes, that's makes a lot of sense!  It's a mode made especially to improve the longevity of the battery!  And if you are especially concerned about that, you do it anytime you are leaving it overnight, instead of just long term storage.

[Anubis-R]

Thanks Guys for the LPR idea 
That's perfect for my daily use 

For your information, while using the LPR mode :
- it does not take into account the Amp limit. and it's not adjustable neither
    --> it charge with the fan ON.That's not a big deal for me but it can be for some

- it stabilize at 80%, not 87%
    -->  fit me well but also may not be sufficient for some

[togo]

Interesting. Put well if it stabilizes at 80, going to 87% should be a very deterministic amount of time. So maybe you switch it back to normal charging a certain amount of time before you plan to leave.
