... to manually set the amperage level of their charger.. if this is set higher than the EVSE, the breaker will trip.
And the max amperage of an EVSE is dynamic. I had one here that typically gave 8A on three phases each without problems, and the other days tripped when only pulling 4A. I assume the station communication signal will have sent this info, but my charger is (currently still) not able to read this.

@DonTom: The SR/F is different, as Zero has (probably) correctly implemented the full charging protocol including the reading of this max amp signal. DigiNows do not read that signal as do currently no other third party solution for the Zero SR/DSR/DS/S/FX/FXS line of bikes.

Yes, Don. That is the video we used to remove the original charger.  Installing the new one was the reverse of that process. The only hard part is reconnecting the charger's connectors to the bike's wiring. Tough on the fingers and quite fiddly. But I think there were only two or three connectors, total.
Is it possible to get inside of the charger, or is it all sealed up tight and impossible to work on?

Completely sealed.

I have to admit, I've been disappointed with the acceleration of my DSR.  I figured with "116 ft-lbs of torque" it would be much quicker than ICE bikes with say 80 ft-lbs. of torque, but it's not.
Read my post above. Your "ICE bikes with say 80 ft-lbs. of torque" do not have 80 ft-lbs. You must multiply that value with the gear multiplication factor. And then it is much higher. No wonder, the DSR does disappoint you then...

What I see very often is that people forget about the gear multiplying effect on torque that ICEs have. They compare the torque directly out of the motor, which does not make any sense.
 I don't know the exact numbers for the Africa Twin, but a friend's BMW has a gear multiplyer of 2.7 in first gear and still 1.5 in sixth gear. For the Afrca Twin with a torque of 98Nm that would mean a whooping effective torque of 265 Nm in first gear and 147 Nm in sixth gear. So, the 146 Nm of the SR is not really "much higher" at all.

Yes, you need to have the right RPM for the ICE to get the max torque, but with 265 Nm there is a lot of room, if you are not in optimal RPM. And don't forget that the ZERO SEVCON does only give you the max torque when running over 30mph. From the start (0 mph) the max torque is much lower.

Anyway, yeah, if you used to ICEs the different power curves and torque availability might give you a problem in an unexected moment, but that has nothing to do with the often falsely quoted "high torque of electic motorcycles".

Zero Motorcycles Forum | 2013+ / Re: Charging cables burning up.
« on: June 28, 2019, 02:25:10 PM »
My bike had been charged for about two years (and about 17000 km) on my wall socket in my garage (220V). I always followed the advice of plugging in first the bike and then the wall socket (and vice versa when unplugging). So far, I did not see any visible damage.
Nonetheless, I replaced the wall socket against a new one as I had a 3 phase line installed to my garage. The new socket is extremely similar to the old one, consisting of the same 220V socket, but instead of one phase has additional two phases.
 
My electrician recommended me to instead install a CEE socket (which is much more durable), but that unfortunately didn't meet the WAF.  ::) Instead I had a switch installed into the 3-phase wire, so that the whole line can be switched on/off electronically, which has the additional advantage that it can programmatically switch on the power only over night when it is cheaper.  ;D

My dsr doesn't lose power till it's gets down to about 15%, than I can only get up to 70mph.
My SR starts limiting power at about 60% SOC. It may not be noticable for you, but I am sure yours does, too.
Have a look at the MBB logs:
  • at 58% SOC: "Batt Dischg Cur Limited    671 A (97%), MinCell: 3642mV, MaxPackTemp: 22C"
  • at 55% SOC: "Batt Dischg Cur Limited    611 A (92%), MinCell: 3597mV, MaxPackTemp: 23C"
  • at 50% SOC: "Batt Dischg Cur Limited    577 A (88%), MinCell: 3611mV, MaxPackTemp: 25C"
  • at 45% SOC: "Batt Dischg Cur Limited    529 A (80%), MinCell: 3571mV, MaxPackTemp: 25C"
  • at 30% SOC: "Batt Dischg Cur Limited    476 A (68%), MinCell: 3518mV, MaxPackTemp: 27C"
  • at 20% SOC: "Batt Dischg Cur Limited    469 A (67%), MinCell: 3548mV, MaxPackTemp: 28C"
  • at 10% SOC: "Batt Dischg Cur Limited    373 A (54%), MinCell: 3464mV, MaxPackTemp: 41C"
You may not notice this, if you are not trying to use full power, but in general the bike is starting to reduce power from about 60% SOC, first only slightly, but in the end you only have about half the power you get when fully charged.

Thanks for the replies. I am still somewhat surprised on the low amount of feedback, though. How many Belly Pan Chargers have DigiNow sold? Probably quite a lot I guess. Maybe we are still too early in the year. :)

The Zero is actually pretty perfect for low speed manouvers. The only thing where it has a slight disadvantage is going on a straight line very slowly (2-3 km/h). Here the thin tyres make it more unstable, but the Swiss exam conditions (10m in minimum 15 sec) are still doable.

[...] 30' diameter
Is that feet? So, 10m (sorry, I am not so familiar with imperial measurements)? I think the Zero can do a 5m diameter turn, so it should be pretty much on par with many other ICE bikes.

In general: Yes, sure. Take the Zero. It will be much more fun for you.

Has anyone bought and used the DigiNow Belly Pan solution?

If yes, what are your experiences with:
  • max charging power: How much was the maximum charging power you ever observed?
  • Temperature increase in the Belly Pan: How fast does the temperature raise and do you see any loss in charging power wirh rising temperatures?

So that brings us back to Dennis-NL's question of what causes the third DigiNow to cost so much more than the second...

The third charger would produce a total of 96Amp of Dc current to the battery. The AUX port can take 70A continuous so it is required to have additional wirring to the controller for the third charger so the two first produce 64Amp to the 70A connetcor and the third charger send his 32A to the additional added AUX port. Also most station give 30 or 32A AC and this is fine for 2 charger but when you ad a third one, it require additional J1772 connector ( for north america user mostly as we dont have the meneke 3 phase system)

So that's what add cost..

Doc
Is there any reason to use both inputs (aux and controller) versus just connecting all three chargers to the controller?

Thanks.
I have considered the Diginow option, but I have not been able to know if it can be put on an FXS, and, in case the answer is yes, how it should be installed. It seems that it is not a feasible solution when you are in France...
Hi Gerard

I had mentioned the Diginow option to you on email and I myself have ordered an onboard solution for me from them, because I think they have a very good product. Their chargers clearly work for FXS, too.

Having said that, I should mention that I had used a self built (offboard) charger for more than a year now, and I have been pretty happy with it. I do not think that there is rocket science in charging EV batteries, as long as you use proven dedicated chargers. There are many professional chargers and charging controllers out there (one of them being mentioned by you). Diginow, however, has the experience with Zero, a unique integration with the Zero BMS (which is not necessary, but very nice to have), and a great onboard solution (thanks to @doctorbass belly pan).

However, I need also to mention that Diginow is essentially a two persons company. There is Brandon (the technical guy) and Morgan (the sales person). And that poses limitations to their capabilities. So, while Morgan has greatly improved the sales activities of Diginow (which were non-existing before), there is still a lack of delivery capabilities, unfortunately. I have ordered and payed my chargers four weeks ago and so far have been completely unable to get a delivery date (even only an estimated date) from Morgan. The same concerning installation or usage instructions. This is currently pretty frustrating for me and other European customers (not mentioning the European distributor, who has not get any more infos from them either).

So, honestly, if you are interested in an offboard solution, I think both ways forward a possible for you:
  • Get a Diginow charger: Professional, well tested product, at a steep price and an unknown delivery date and (unfortunately) lacking customer support in Europe
  • Build you own solution: Use professional chargers (e.g. the elcons) with a proven controller. Pay a much lower price and get the charger delivered soon. Test the voltage output before connecting to your bike. But generally you clearly have a somewhat higher risk and no customer support at all!

Do you have the connection to the charge signal wire in the Anderson plug?  If not you can’t charge.

You can, but you need to key the bike on.

« on: July 02, 2018, 10:33:30 PM »
Well, let's say there are many people using successfully offboard solutions. That is: Professional chargers that are programmed to work within the limits for the zero battery.

However, these solutions do have their risks: Most are not waterproof. Get a rain shower while charging may fry the first the charger, and if you are very unlucky, also the battery (e.g. if the waters shorts the input and output of the charger. Same thing may happen, if you get a wrongly assembled/programmed charger.

So, there clearly are some advantages with the DigiNow solution: The two guys are real experts, the chargers are water and shock proof. Additionally the latest controller has a lot of features (e.g. charging to 80%). And, of course, the DigiNow chargers can be used offboard, too. The only point is that a 6.6kW version is something about 3k USD, so there is a price preimium you pay for the quality and expertise.

Cheers

Michael

P.S.: And don't believe that ANY company will cover your battery, if something unexpected happens. So, if you use the Diginow chargers and some strange coincidence would blow up your bike, don't couiunt on the guys to pay for a new bike. :) Whatever you do, the risk is always with you alone.
