Punxatawneyjoe Posted January 22 Share Posted January 22 20 minutes ago, Paradox said: Your response is to post a video from 5 months ago? Is time a factor for proving how amusing "faster " would be for this wheel? Do you think the re-designed the wheel since then? Quote Link to comment Share on other sites More sharing options...
Planemo Posted January 22 Share Posted January 22 I saw that vid when it came out, I remember thinking it really didn't seem like he was pushing the wheel to me so I was pretty surprised to see it go down. Low battery? Dunno but I've seen a lot of EX30's pushed harder than that (or at least they looked like it!) Still sitting on the fence re updating firmware, if it's all about increased speed I'm not interested as I'm never on the limit as it is but if theres anything else of interest in the updates I might consider it.

Monoxplorer Posted March 9 Share Posted March 9 I'm curious if anyone here has ridden both 50E and 50S EX30s, and if you've noticed easier torque/acceleration? Also is 20amp charging true on the 50S version? Frankly 2700-3000wh isn't enough as much as the newer higher voltage wheels are tempting, and as I love my EX30, a 50S version is what I'm going with as I want a bit more oomph without worrying when I'm drawing 70-100+ amp current and riding to lower battery levels.

What speeds you riding? I did notice a difference in torque with offroad mode with mine but back on race mode now with FW set at 5. If I'm not mistaken the charge board will limit charging rate and voltage. Edited March 9 by Crab 1 Quote Link to comment Share on other sites More sharing options...

Usually 30-50+mph, but I rarely go over 40 once my battery levels get down to -60%, just because I've seen too many cutouts and not interested lol I like fast accelerations and ride streets so quick pushes happen often. I read somewhere that CP 50S can charge up to 20 amps so if that's the case I don't see why the EX30 wouldn't be. Quote Link to comment Share on other sites More sharing options...
Robse Posted March 10 Share Posted March 10 For all of you Ladies and Gentlemen who (pretend to) know everything about what Field Weakening is, read this excellent little note below. I have done that myself. Before I knew nothing, Now I know something more than nothing, but not enough to still not be confused, just more than before.

Thats correct, and unless someone can show that the 50S version has a different dist board to the 50E version then I suspect the limit will be the same.

My understanding is just that. I’ve heard you can do 12a up to perhaps 85 percent then need to back off to 9 or so to finish. I am running the 330 test firmware with field weakening that Dawn and Roger liked, I doubt I will ever get it to kick in but it feels great. Super stable ride without the annoying dip fwd and back, even off-road mode felt really nice. Edited March 10 by Crab Quote Link to comment Share on other sites More sharing options...

Yeah I heard the same, although one guy on this forum couldn't continue with a reduced charge at all after it cut at 75%. Seems odd but thats what he reported. 11 minutes ago, Crab said: I am running the 330 test firmware with field weakening that Dawn and Roger liked, I doubt I will ever get it to kick in but it feels great.

I don't notice any dipping either unless you're talking about when cornering which I'm kinda used to as it was the same on the Sherman. In any event theres an adjustment for it in the Begode app which I haven't touched so shows how much I'm not bothered by it lol. Quote Link to comment Share on other sites More sharing options...

The dip while turning sucks imo, set it to 4 or 5 for flat pedal turning. 1 Quote Link to comment Share on other sites More sharing options...

Planemo Posted March 25 Share Posted March 25 OK so what sort of amp alarms do people run in EUCW with their EX30? I had 'current' set to 30A and 'peak current' to 60A which is clearly too low as I have alarm blobs plastered all over my EUCW logs. It seems I peaked to 61.3 and was often hitting 30~40A whilst doing some 'spirited' accelerations (but not crazy compared to many!). I can't seem to find any info on how much sustained current the EX30 is happy with. Anyone got any ideas? Quote Link to comment Share on other sites More sharing options...

Maximum motor current from pull test goes up to 219A! 8 hours ago, Planemo said: spirited' accelerations (but not crazy compared to many!). Or you have still very much safety margin... For mosfet burden only motor current is of interest - power dissipation is proportional to the square of the motor current. You can enable data logging and look which current value is used. Just looked it up - in @RagingGrandpa's logs is a column for current (battery) and current_phase (motor) Quote Link to comment Share on other sites More sharing options...

Maximum motor current from pull test goes up to 219A! I'm not sure, I thought Begode were using true current measurement now? For sure, the current alarm settings I used to use in my MSX had to be a lot higher (like 90A) than what I am seeing on my EX. On 3/26/2024 at 8:05 AM, Chriull said: Or you have still very much safety margin... Going by the log for the same ride, minimum margin says 35%. I can't tell if this occurred at the same point at my 61.3A peak though because the CSV doesn't show safety margin, I guess it's calculated within EUCW. It was short ride so I don't think anything was based too heavily on any major voltage reduction. Edit: Just looked at the CSV log and found the safety margin column - when it hit 35% margin the current was actually 70.03A, but at the same time it recorded voltage at 120.7 so thats prob why the margin got a bit low. Oddly, I don't know why the home screen of the tour on the EUCW website shows a peak of 61.3A under 'wheel statistics' when it's clearly 70.03A on the CSV... In any event I guess I need to raise my current alarm up to at least 80A, maybe 90. Edited March 27 by Planemo Quote Link to comment Share on other sites More sharing options...
Mike Sacristan Posted March 31 Share Posted March 31 Samsung 50E cells in 6P can do 60A continuous and they can handle 90A though I wouldn't do it for a long period. Which would be quite difficult to sustain anyway since it requires heavy accelerations at already high speed / amps. Some 4P wheels with LGM50T/LT which have a 7.3-14.3A rating depending on temperature have been know to high amp overlean at 56A. Set it to 80A for now and see how often you hit the alarm. Next time I ride with Simon I will ask for his stats. His riding weight is 100kg and he is as aggressive as they come. 1 1 Quote Link to comment Share on other sites More sharing options...

Thanks Mike, I was aware of the pack capability but had less knowledge about what the board etc could put up with. I think you're right, 80A would be a good peak current alarm figure. I don't think I will hit it that often tbf but I would like to have something set up just for those 'hmm am I asking too much up this hill at this speed' occasions. 16 hours ago, Mike Sacristan said: Next time I ride with Simon I will ask for his stats.

I am about 95kg riding weight so pretty similar and by the sounds of it I'm not nearly as aggressive so his setting would be a good benchmark 1 Quote Link to comment Share on other sites More sharing options...

But Simon and I tend to drag race... and we have done so at 80kmh wheel reported as well. Although Simon does get a bit nervous when he looks down at the display and see 80 something. Snow storm today so I won't be getting any stats... but maybe this weekend. 3 Quote Link to comment Share on other sites More sharing options...
