Bringing this topic up again in the hope HD reads soem of this and factors it into their product development, or aftermarket "customising" options are emerging.

Loving the country road rides with my LW1, however, road options are limited to CCS2 fast chargers and slow overnight chargers along the way. Looking for options to upgrade the sloowww onboard charger with an adjustable AC charger allowing for slow overnight and ramping up to faster AC charging. At least 3kW but the more the better. Technically replacing the current onboard charger with a similar sized unit, replacing any fuses and some cables or so, might still fit under the tank. 

Any thoughts? Anyone working on this or is HD just to hard to "customise"?

Setec makes portable 10kw CCS chargers you can plug into a 220 volt outlet: https://www.setec-power.com/10kw-dc-fast-charger/

H-D cut corners on the onboard charger and used the weak 1.3kW one because it was cheap. Obviously there was room for more if they put a turbocord under the seat. I don't see any feasible way to "replace" the onboard unit because the CAN communication will freak out if you put something in there that it doesn't expect; how did you intend to communicate with the bike? Also, it's almost a sure thing that the fuses from the onboard charger are small and will pop if you tried to add more current, so that's another thing you'd have to investigate.

If you just tried to add another independent charger to bolster the onboard unit, how would you tie it into the battery then? Do you tap into the inverter?

Without being able to reprogram software, it’s likely not possible?

It may be possible for someone with a giant brain, but I don't see a way to do it.

Sayyed at Elcon owns a Livewire. He is probably the one to ask. He programmed all four of my Elcon chargers for my Zero motorcycles with no communication from the bike required. They all just turn off at 95% SOC, which is fine with me. I connected mine to the DC contacts on the motor controller on both my Zero DS and Zero SR. I wonder if the same can be done on the LW.


I use two 2.5KW Elcons on my Zero DS. I charge it at 6.3 KWs when on the road. It has the smaller battery, the 7.2 KWH.


On my Zero SR (with power tank) I use two 3.3 KW Elcons. I charge the SR at 7.9 KWs where possible. I have ways to lower it to not overload the charge station.

Looks like a typo... not much use requiring 300V input is it

AC power connection   3P+PE
Single Phase 220Vac (195V-250V)

I had one of these, plugged it into a NEMA 6-50. You could charge a Ribelle at 6kw

Hahahah no

Entirely different beast, Don. Zero was built with the option for accessory chargers. The Cypher II bikes have an Aux charge port with a 100 amp fuse. On top of that you could, without much issue, access the controller directly and just tie chargers to that.

The LiveWire has none of those things.

Well it must have a way to get to the battery somehow, I would think. What would be required to do to charge the bike besides using the LW 1.3 KW OBC?

If you continue to not read the things I post then yes, absolutely. It should be totally simple. Have fun!

I probably missed a few dozen of your messages as I do not have a LW. This is just a curiosity to me.


I assume the problem is mechanical, not electrical, with charging the LW. After all, they have that mickey-mouse 1.3 KW charger in there. What the big difference between it and other AC input chargers?

What the big difference between it and other AC input chargers?

The hurdles for increasing AC charge rate above the rated specifications given by Harley are going to be both software and hardware related.

There is no reason the electrical: HV wires, fuses and circuit board components of the AC system would be designed to carry more current than what the stock charger can provide. Parts rated to carry more current cost more money.

If you were able to upgrade/redesign all the parts to carry more amperage. The next step would to modify the software to allow communication between the bikes vehicle control unit and the new larger charger along with increasing the max current it can request.

Anything is possible but it would be a monumental project.

Another option would be to mount a external DC fast charger (like the 10kWh Setec unit) on the bike. This could be powered by a J1772 AC charger. Then all you would need to do is plug the CCS from the Setec into the bike.

c'mon, man, I said that in the third post of this thread
