Title: Improved AC charging options - 1.5kW -> 15kW?
Post by: manlytom on January 06, 2023, 08:16:08 AM
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"?

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?

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.

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?

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.

Post by: manlytom on February 04, 2023, 02:19:08 PM
Thanks all, solid discussion of options, bummer the LW is rather limited and locked down. We would have to wait until Harley releases some more details or need to brace reverse engineering it, changing HW and getting SW to talk...
I will investigate the Setec unit but will be a beast to carry on the bike. CCS2 plug, cable, Setec unit, AC 3 phase cable and plug... The 10kW Setec unit itself is with 420 x 330 x 161 (assuming to be cm) not to large. The plugs and cables will make it bulky.
Before I ask for a quote on the website, anyone has a rough idea on cost?

Post by: manlytom on February 04, 2023, 02:22:14 PM
And as a far easier option, Tesla has started to open up some of their Superchargers in Australia. They are along very scenic country rides. Therefore ideal. Anyone been charging their LW on such supercharges?

The Setec chargers are $3600.00 here: https://www.evseadapters.com/products/portable-chademo-ccs-combo-dc-quick-charger/

Yes, the cables and how bulky they are is what will make this all hard to strap on a bike. I played with a lot of ideas to put this on a Ribelle and never came up with anything that would be practical.

guess we stick with the bike as is and for now just customise the seat and so on, once warranty is expired still keen to hack it.... In any case, loving the LW and hoping HD continues this.

Some time has passed. I think the infrastructure will move perfectly into the LW use case. Overnight charging on AC and DCFC when charging is needed on the go. I think it was pretty smart for HD to set it up that way.

There is no money/R&D going into making higher power AC inverters smaller or more efficient. If the industry isn't doing it, then hobbyists will have a very tough row to hoe trying to do it themselves. It's all about battery chemistry and motor power/efficiency right now.

Now with vehicles getting 70-100 KWH battery packs and chargers pushing upwards of 300KW charging speeds even a 50KW charger can be considered a "Destination Charger"

Look how many Plugshare checkin's list 25kw chargers with "slow charging rate" and only stayed for a hot minute to get enough juice to got to a "real" charger that can push 100kw or more.

The reality, at least here in North America, is that there are so few electric motos on the road that we just can't collectively move the needle in our direction. (LW sells a couple hundred a year, globally. Energica sells more but not orders of magnitude more) We have to be able to go with the flow. There will be fewer and fewer AC public chargers and none of them will get upgraded. They barely get repaired.

HD went all in on DCFC and provided the bare minimum functionality with the AC charger. I think it's more reading the writing on the wall than cutting corners. The only dumb thing they did was price it at $30,000 before splintering it to it's own brand.

LW and Energica owners are all posting about getting faster Level 2 charging, while Zero owners are wishing they had DCFC instead of max 12KW AC.

TL:DR

Give up on cobbling together some faster AC charging solution. Your time and money is better spent pushing the infrastructure to have all the DC Chargers you need.

It depends on where. AC charging will always be common, especially if you include Tesla Destination stations which I often use on my Zeros as well as on my Energicas. Free AC charging is just about everywhere you look in Reno, Carson City, Gardnerville NV, even some free AC charging here in Auburn, CA. The big advantage of AC charging is every EV made can use it, in one way or another. Could need an adapter in many cases, but that is not a big deal. And it is also common at home and in some motels.


Also,  free AC Charging at many city halls, such as in Sparks, NV or in VA City, NV.



Not much need to repair them, they are cheap enough to replace. Not a whole lot inside of them. They are just 240 VAC supplies. I would be just as happy with a 240 VAC 14-50R. In fact, I prefer such as can usually get a lot higher current direct from a 14-50R than a J-1772 which can be as low as a shared 3KW which means 1.5 KW each side. 


I find the big problem to be unreliable CCS.


A few examples:



1. Hawthone, NV. Totally dead for more than a year.
2. Fallon, NV. Totally dead for more than a year.
3. CA I-80 Donnor Summit East, CA--totally dead for more than a year.
4. CA I-80 Donnor Summit West--totally dead for around six months.
5. Incline Village, NV, dead for around seven months.

On my 2020 Esse Esse 9, I could get to more places three years ago than I can today.

You're kind of a unique case Don but let me ask you this.

If you had to give up a KWH of battery capacity to gain another KW of AC charging speed how many would you give up? If you had to add $2000.00 to the purchase price and 25 pounds for every additional 3.6 kw of charging speed with a permanent 15 liter top case you couldn't put anything in what would you spec your bike at?

or....

If all the CCS chargers worked 99% of the time and they were every 50 miles but you had to post regularly and advocate for that on Tesla, Hyundai, Kia, and other EV Car forums, blow up Plugshare and charge network provider's apps/websites,  and email your state officials on the regular to ask for it.

Which one would you choose?

When are you going to learn, it's not about reading, it's about being read :D




Setec DOES make a charger that will convert 240 AC single phase to DC fast charge,  they can actually custom make a charger for you too if you talk nice to them to pretty much whatever specs you want.  I had them make me a custom 30KW charger that runs off 240 Mains input.  It's modular so if I am at say a track garage and there is only one 30 amp input, I only run one of the modules and get what I can out of it.  When I am at home where I have 400 amp service, I can push what I need thru it.

The 10kw ones are a stock item and if you order one should ship very fast for you.

The price of the Setec charger is a bit expensive, especially if you buy it 3rd party.
Try talking to them directly, you should be able to work out a much better deal with them and they can have FedEx deliver it literally to your door. I got my 30kw fast charger, delivered to my door for under 5k.  I'll post photos when it actually gets here, it's enroute now.

Perfect for me will be 25% more range than I really need to get between chargers every one hour of riding. 


What bike I take will depend on the type of charge stations on the way.

its adjustable to 9-20A output (ccs1/ccs2)

it cost 800$ without shipping

Post by: Specter on January 17, 2025, 08:22:48 PM
It's still going to be bulky.  Will need a 50 Amp plug in, and the cables.  Overall will weigh probably 50 lb or so.  I see them at camp grounds and the race track but otherwise 50 amp for the public receptacles.. not so much.

I think as big a problem is not only going to be, having a charger, but somewhere that can power it as well.  If you carry a handfull of pigtails you can easily adapt and then tune down the amps to whatever receptacle you can find but still.. thats even more room and weight you'll be carrying.

Good find though!
Shipping will probably be 300 ish dollars. unless you saddle it with another shipment and then hand it off once it gets mainland then you may get it for around100 to 150

main problem is that - CAN comunication is unknown - so it has to be reverse engineered and flash bike firmware so it is superhard (CCS comms is open so easier to to with external output - always you can mod it to fit inside bike or on seat, and instead ccs plug you can solder cables direclty



I just ordered 20kW 3phase from this company - weight 35kg and sea transport cost 240$ so maybe for 7kg will be about 100-150$

I am in EUROPE so i dont know prices to US or other countries

EDIT
from my knowledge live wire has 70S battery so only about 220-290V range voltage, charger has 20A max output so power will be about 4,4 to 5,8kW in real life _
With 240V it need about 25A breaker then (in EU) i know US has 240V but split phase (i am not familar with it)
anyway its adjustable, always you can charge with lower power

I’m looking forward to these improvements in AC -> CCS chargers. I didn’t even know it was a thing until I saw the one at the South San Francisco Energica office. Maybe someday they will be small enough for someone to hard-mount one on a Livewire with a Tesla port for 12 kW AC charging. Livewires will be relics by then, but it would still be fun to see.

technology is already here
SiC
silicon carbide - its possible to achieve 3kW from 1L capacity with 96-97% efficency so with proper cooling its easy to fit 6kW in live wire



meanwhile energica for example still using 3kW charger which was also mounted in first volvo plugins in (2011-2012)


EDIT
I want show to you my 120$ ebike charger
pic in attachment

 1,8kW server rectifier/psu with CAN controll added - only 0-100V range but 3 of them in series and I can charge livewire in theory with 5kW easy (also from 1 or 3phase)
weight 1,1kg, volume dimenions 1L, only if original CANbus can be updated in bike or something

also this PSU is from 2012-2014 I think

Putting them in series.  What's the insulation rated at?   That could be putting an awful lot of stress on each component.  If the dielectric value is not high enough, over time it's going to find it's way home in a bad way.

I am not gonna use it, i have external DC charger

my point is - this small charger has 1,6-1,8kW at 230V, and cost 120$, HD charge 5000$ for less power - and I know - chagrers have to be safe etc, but this shouldnt cost that much - especially these while they die a lot

It costs a lot because it's critical, you can't run without it, they got you by the balls.

A printer cost 80 dollars, a few teaspoons full of ink, which is little more than water, and some coloring, cost 180 dollars.  Why?  Because it can, you NEED it, it don't work without it. they got you, that's how they get their money.  Lets punch out a bunch of cheap ass chargers, keep the initial cost down, and then sock it to them when it fries a year or so down the road with a 3g ticket for a new one.  Yep, sounds about right.

yes, same with my stiga lawnmower tractor - battery cost 95% of price of whole new vehicle, and you can't buy BMS - its has CAN communication so if bms fails in future (i hope not) I have to sell whole tractor for parts

My first charging today (AC)

previous owner said - OBC was replaced but I can't charge it today :(

I have 3 evse:
- my tesla mobile connector (hardwired) works with car
- tesla mobile with shucko adapter (this one I get with bike - shorter cable, but before I bought i tested it and it works)
- mennekes blue evse (shucko 13A)


at first I plugged all three one by one - no reaction - energy meter 0W but bikes give me estimated time to full 1:20, I waited 5min but nothing happed

so I shut the bike off - and start plugging once again - this time - mobile connectors relays click and I got 4-6W on energry meter, but no charging

last one I plug this blue mennekes whie bike was off, and after few seconds charging started


also weird thing - OBC is power limited not current like in other evs

this mean you will always get 1660W power - if voltage is 250V then 6,7A, if 200V then 8,3A

unfortunanetly not work with HD, with energica it works

battery it has two DC connectors

from CCS socket directly to battery (separated plugs HV+ and HV-) on back side

also from OBC one connector to battery (top side) which is

PLUG PN 1-2103015-1
SOCKET has only these numbers 1A PA66-GF33 HVA280


I wondering if I make simple Y type splitter - properly insulated and to other DC+ and DC- I put custom 294VDC max charger (for example 10A) I will get about 4-5kW AC charging possibility

UPDATE:
my DC charger now works

it has to be connected in certain way
1. CCS PLUG to socket of harley
2. switch breaker on charger
3. wait for boot up (10-15s)(just wait for green LED)
4. start charging on LCD
5. works

also voltage has to be set up at 760V - I dont know why, but with 760V and start up procedure it works

I tried with HD two times, energica one time and tesla one time

after few months I will make update if I had any problems
