Use of petrol generators to charge
« on: March 05, 2014, 04:17:23 PM »

Hi folks, was wondering if anybody had experience in recharging using a portable petrol generator? Would a 2000W generator be sufficient to charge a Zero S or DS? I take it that it should be able to as from the specs the bike draws 1300W when charging?

There was a thread about this a while back. The generator has to be rated somewhat above the staedy state pwoer of the charger. I had to go to a 1600W unit in order to operate the 1050W charger in my 2010 and 1012 DS's. An 850W does not operate the 640W charger in my 1023 FX.  :(

You will be OK with a 2000W unit if you are only using the one charger in the bike.

More about this in the earlier thread (I think it was originally about solar charging)

If an 850 watt isn't enough for the 650 watt FX, then a 1700 watt won't be enough for the 1300 watt S or DS.

You probably need at least 2000 watts continuous.

Moidore,

I am looking at this as well. Right now I am looking at a 5500 watt (continuous) generator to run the internal charger and 2 quick chargers for my SR. Should have enough left to run a small coffee pot so I can enjoy some good brew while the bike is gettting topped off. Will let you know what I get and how it works out.

The problem I see is not the continuous Current/Watt it is the inrush current of the Meanwells.

The Delta-q had much less inrush current that should be the reason Trikester had less problems with the 2012 Model.

You can see the Meanwell has up to 70A inrush and you have 2times for the FX and 4times S/DS. (Photo 1)

It will be not so much with 120VAC as with 230VAC. And the real world value not in the extreme cold will help too.

But this is always the problem to decide if the generator is able to deliver this.

I have done some testing with my RSP-1000 Meanwells claimed to have 25A/110VAC and  40A/230VAC. I tried to use current limiter to start it but there must be a regulation circuit I could not trick. It has used a bit lower current but much longer ???.
The Oscilloscope photos are the native current use of the RSP-1000 at 230VAC so it is less 30A and not 40A as the given worst-case and only for 2-3 Sinusoidal waves.

I'm about to buy two Honda EU2000i generators (one the "iC" model to potentially link them).  With 1600W continuous (and a reputation for clean power and being able to punch above their weight), I'm hoping this should be plenty to run one Delta-Q Quiq charger each, and maybe try to use the onboard charger as well.  This'll be my camping setup.  Mostly I'll be charging just the batteries while I'm off riding, probably just use one gen and onboard charger @600W if I need to charge overnight to keep the noise to a minimum.

I also had the Honda EU2000i in mind, the other alternative is the Yamaha EF2000is. I thought the onboard charger also draws 1300W? Let us know how it goes with the Honda generators.

I think an EU2000i could probably charge one Delta-Q QuiQ, but almost certainly will not charge the onboard 1.3 kW charger on the S / DS.

My 2012 bike drew about 950 watts, max at the wall.  My 2014 bike draws as much at 1450 watts right before if finishes charging.

('13) FX is only 600W onboard, not sure what it peaks at as I've never measured.

My FX seems to charge at 640 to 650 watts. There may be a variation.
