Forgot to mention that it's probably a good idea to limit one unit to 10A and use the onboard for the rest instead, so you won't need any further signaling on the aux port because the onboard triggers the contactor.

Thanks I just have 2 of these flatpack2 2000, because they are long and a bit heavy I plan to just use them at home using 240v.

most of the rides with my FXS use only down to 60% soc and take 3-4 hrs to get back to 100%. But all the rides I would rather do get down around
15-25% soc and take 8+ hrs to get back to 100% and limit me to 1 ride a day. And thats ok because I was in a accident severeal years ago and
cant ride long anymore this is why I got the FXS with the smaller battery and lower price. but it will be nice to be able to quickly charge up
and go riding again if I wanted to.

    I finally did some testing tonight. Made some temporary plugs using spade female terminals and ran 240 from my air compressor to power the charger. I was at 70% and the onboard charger said 3:20 for charge time. Plugged in one Eltek and its down to 53 minutes. I was also running the factory charger for total of 3.0-3.3kW. I have some screen shots below while charging to show the readouts.
     Based on my app I am at about 90% charge at 113 volts and 92-100% at 114 volts. During the balancing cycle the voltage starts at 114 and finishes at 116 volts once done balancing. So i will be setting the chargers to 113 volts to get me to 90-92% before tapering down and letting the onboard finish. Because my charger was set to 115 volts I disconnected it. So I will have a better understanding on how it reduces wattage with the setting at 113 volts. It was still putting out 600 or so watts at 114 volts to finish the charge to 115 volts. I will see how the 113 voltage setting works after my next ride and recharge.
     Need to order correct plugs, larger silicone cable and other items before I run three and pull more amps. I have 60 amp 240 drops at work I will try those on before I test a EV station. Pretty impressive. Exciting for the first time doing this. Below is a picture of my test with my cheap harbor freight meter. Its off about one volt from some of my good meters.

Any ideas on how to get the bike to charge without the onboard charger or without keeping the key on?  From some reading I have done it looks like the center pins on the Anderson are looking for voltage input to activate the contactor? 

    I found also that if you have the aux. charger on only and you try to power the bike on it wont go and it makes a beeping noise about every three seconds and the contactor wont close. Same happens if you try to plug in the onboard with the aux charger plugged in.  Must be a safety to make sure the contactor is closed before applying voltage. If it senses voltage it wont close the contactor.


I took this screen shot while running.




This screen shot was at 100% but balancing on the factory charger only.

If it helps, I've been charging my FX with only the auxiliary Quiq charger. Turn key on,  plug charger into bike, plug charger into wall, when charger indicates charging and charge time shows on dash (can take a few seconds), turn off key and charging continues. I can plug in first then key on, as long as I do it quickly enough.

Currently just plugging into the +\- into the auxillary after turning on the key it will charge but I wont see the charge indicator. I can however see it charging on the app. Does your quiq charger use the center pins to trigger the charge?

Quiq charger has a 10k pullup to 5V on the center pin. That won't start charging without the key or onboard to begin, but it will continue charging and indicating after key off and onboard off.

One of the male center pins is present, maybe the females.

Didn't know that Zero is doing it this way, thanks for the hint. EVTricity is doing the same, seems to work well. Another solution I already tried successfully: a USB powerbank with a USB cable with +/- wired out. Connect powerbank- to battery- and powerbank+ to the aux pin. By connecting and disconnecting the USB cable while the bike is keyed on you can enable and disable charging mode. Once enabled you can turn the key off.

Lenny. Did you connect this thru the pin on the Aux port?  I see there are two pins. Which one would be considered the one to use for +. I looked at the 2013 schematic on the unofficial manual and it shows the aux pins going the BMS. From my reading the BMS is what turns on the factory charger and activated the contactor.

Those two pins go only to the MBB on my '16 FX. They are not found on the pack connectors, so they're not connected to either BMS. But they do go to pins 38 and 40 of the MBB as Burton's 2013 wiring shows, but directly not through BMS. As shown on the Y cable schematic they are separate enable lines for two chargers. Adding a 10k 5v pullup to either pin will keep the contactor closed, but external charging must always be started by key on or onboard. https://zeromanual.com/index.php/Advanced_Modifications#Charger_Y-Cable

Now I understand. That makes sense now. When I read the section about the Y connector that you posted i though that the circuit needed to complete with both pins. But that is how it knows two chargers are hooked up on the Y.  I was trying to make sense of the pins but your explanation did it. Ill have to give it a shot.  Keeping the bike in charge mode once initiated is what I am looking to do so the key can be taken out. Thank you for the clarification.

Trikester's enable is one possible way http://electricmotorcycleforum.com/boards/index.php?topic=4588.msg30634#msg30634 I've used three aaa battery's, a 10k resistor and a switch. I have that set up for closing pack contactors off the bike https://zeromanual.com/index.php/File:Pack_discharge_adaptor.png
