The bike now has a little more than 10.000km and is a 2016 SR.

As for the 49 Minutes I can‘t remember what happened during this time. But I will monitor my next charges and corresponding logs a little closer...

Hi,
hope someone can help me out solve this riddle. Recently I installed the Otten charger after my OBC got "kaputt" 😊

Now, when charging, I experienced a jump in SOC from 86% to 100% on the dashboard. I opened the app, it showed 100% as well but the bike was still charging und cell Voltage was at 115V. When I checked my BMS log today I found "SOC adjusted for voltage" and now I'm concerned. Is everything alright? Why, out of a sudden, did the BMS found such a huge gap in cell voltage? And what does "Voltage Across Contactor: -849mV (Possibly welded)" mean?

I did some research and found the Otten store but found no direct references to the chargers. I sent mail to the shop for info.

Thats the correct way. Unfortunately Otten does not provide a web shop or any other information on their website. But the information given by Lennart is worthier than a link. He sends out a manual of how to install it and explains everything in detail. I decided to have the large solution with two 3,3kW chargers and the CAN controller to communicate with the charge station. I decided to have the latter because I don‘t want to fumble around with manipulated cables and stuff. Just plug in, charge and enjoy a coffe  ;
Note: The CAN controller is only used for the control pilot (CP) signal between the charge station and the charger to negotiate charging power! It does NOT communicate with the bike.

The bellypan solution is nice when considering the used space but I wouldn‘t recommend putting ~750W waste heat underneath the battery.

I didn't really know that there was this alternative available in Europe.

Luckily there is, because the european grid is significantly different from other power grids. Europe uses three phases with a phase shift of 120 degrees. Here in germany the asymmetric load is regulated to 4,6kW max (yes, we do have a thing with regulations in germany but I guess other european countries don‘t like asymmetric load either). Using the Zero charge tank you have an asymmetric load of 6kW because it uses only one phase. Every charge station is able to recognize the asymmetric load and some of them already stop charging in this case. When more electric vehicles hit the market and everyone charges here and there the others may get more intolerant as well. Lennarts charger uses three phases (two of them for the 3,3kW units and one for the onboard charger. Your asymmetric load is 2,0kW wich is perfectly fine. Since my onboard charger died I only use two phases and charge with an asymmetric load of 3,3kW (still within the regulation  )
While everyone is looking for DC charging on Zeros I only have a small wish on my list: a 3 phase Zero charge tank that is suitable for the european grid.

I'm facing these troubles right now as well. Five weeks ago I bought a 2016 Zero SR here in Germany. The only thing that needs to be done is replacing the front brakes. During the test drive I heard them grinding and felt the deceleration varying during one turn of the wheel. The mechanics told me it somehow got a "hit", so my dealer ordered new brakes right away and we agreed to
handover the bike after repair.
As you might have already guessed, we never heard from Zero ever since. No spare parts, no delivery date, not even a tracking ID. Nothing. I started asking Zero Europe last week. They apologised and got after it. But the only thing they found out is that the brakes haven’t been received from the US yet. Well, I appreciate the apology but I didn’t get any wiser so far. Putting a few parts in a box and sending it to Germany is no rocket-science so I dearly hope at least that has happened...

Not only wants my dealer to cut me out of the contract because he can’t see an imminent delivery date, but I also start asking myself if I really want this. Of course I fell in love with the Zero but am I ready to be grounded for months every time I need spare parts? A new tire? What if my BMS decides to go toes up? Reading all your suffering makes me wonder if I made the right decision spending loads of money for a Zero.
