I reasoned that if the Widewheel could do that trip at 25kmh that the MX60 could do it too at about the same speed.
So off I went on this trip:
which yielded this data:
and while average speed movings aren't ball tearingly faster than the Widwheel, the spike of the steep down hill is worth a closer look.
So, yep, that was fun!
Scoot handled it just fine.
While on the trip I stopped for a few pictures.
and
when I got home I checked the ODO and found that compared to the GPS there is still some discrepancy:
so it thinks I did 25.7 and the GPS thinks I did 27.8 ... if I could be fucked I'd probably tune that in more.
But who could be fucked making the ODO show you've done more km? #hurtsResaleValue
Lastly the energy consumption on this trip was 781Wh which for 27.8km is 2.8kWh/100km,which is a little better than I've had on other occasions but then this time I didn't speed ;-)
Happy Scooting
Nice sunset picture and good test. I am also surprised with the discrepancy between gps data and scooter data. Last time I did 41.5 km on a single charge as for the gos but according to scooter screen I did 39 km. 2 days ago I used GPS of Endomondo to track my trip it also showed around 2 km longer.next time I will try to check the speed of both shows different (I heard most of the producers faking the real speed by showing higher than reality).

Hi
ReplyDeleteI'm not sure what your scooter is Ali, but I had to dial mine in with the settings to even get close to reality. See this post for the specific settings on my scoot:
https://cjeastwd.blogspot.com/2020/03/mercane-mx60-my-settings.html
P06 and P18 are key IMO ... but to be honest its good enough for me now (and I don't feel inclined to revisit doing it for a small margin).
I got Widewheel Pro since 3 weeks. After yesterday's ride 39,5 km with one charging odo on the Widewheel Pro showed I did 36.9. haven't compared the speed on odo with GPS yet but I guess there will be also discrepancy here with the speed and distance.
ReplyDeleteAccording to your odo you still have half of the battery left but I guess it's once you stop battery/volt gauge always go up a bit. With the same level of energy use (28 wh per km) you would make around 42-44 km range. The specifications for MX60 says 60-100 km range, so in this case it won't make even 50 km if I am not wrong.
ReplyDeleteOn the other hand Widewheel Dualmotor consumes something around 17-19 wh per km.
Today I had a long trip one app showed 40.8 another one 41.80 tokto riverside with my Widewheel Pro (which on official specifications says 40-70 km which I believe it's impossible-maybe someone with 50 kg weight can do 50-55 km max).
Here is the results from 2 apps. And the same as you said between GPS and odo i always have around 2 km difference (odo shows less)

I think it did not bad
Hi
ReplyDelete(I assume you mean the Voltage shown on dash dial because and ODO only measures distance) ... well perhaps. As I mentioned in the post it took 700Watts to charge it up, so I have under half left. Seeing only the unladen battery Voltage is not a useful indicator by itself.
If you refer to the discharge chart in this post (near the bottom) https://cjeastwd.blogspot.com/2020/02/mercane-battery-test.html you'll notice that the last little bit of power is harder to get out, and so I'd prefer to keep that up my seleve in case (say) I have more head winds on the way home, or I misjudged the hills.
Its common that no two measurement items give exactly the same number. You'll be aware that GPS is deliberately inaccurate to civilians for a number or reasons (military ones). Its possible (with such a small wheel) that there is no perfectly accurage measure (count of rotations) of speed because of the steps which may exist between "settings" in the calibration (assuming you even get calibration).
Ultimately its pretty irrelevant to me because I always allow some tolerances in estimating trips.
Don't forget that speed increases power (even on a flat ground) and that going faster requires more power (which you'll recall is defined by work done over time, get somewhere sooner and require more work).
:-)
Yeah you are right, I meant battery level not distance of course. After a long or tough ride(intensive, speed, hills) did you checked the battery if it gets hot? I noticed the motors getting warmer when you touch the wheels, with the battery it'll be hard to notice as it's under the deck. Maybe with MX60 easier as you have easy access to the battery. Now it is already summer here and yesterday the temperature was 33c here. I read your blog I remember few articles that you didn't notice any higher temperature in summer. As far as I know cells getting warmer at very high charge-discharge rates.
ReplyDeleteIn Poland there was an explosion in an apartment last week and they claimed it's an electric scooter exploded during charging.

ReplyDelete>In Poland there was an explosion in an apartment last week and they claimed it's an electric scooter exploded during charging.
I'm willing to bet this involved some combination of the folllowing: the person tinkered with the battery and had no knowledge; the battery had no BMS; the battery had been in storage for a months and left to fall below critical temperatures.
A classic example: https://www.reddit.com/r/ElectricScooters/comments/f9lvvt/psa_lithium_fires_really_do_happen/
Hi. Hope you are doing well.
ReplyDeleteWhat do you think about putting additional battery parallelly, you know people do it attached to the stem and directly connected to charging port.
I am against this generally and before it was for one reason now it's 2. First thing was about adding a few kg additional burden on the stem which I guess you also aggre. The second reason is actually i just did a quick check(not for the sake of charging my 31.5 ah custom built battery-thats why I wouldn't need additional power) as my 15ah battery is resting since over 2 months after building new one. Just wanted to check if the old battery keeps it's charge and the voltage didn't fall down. The voltage was fine exactly same when i charged before storing it.around 75%. Just connected the output to the WW charging port and what I noticed on the multimeter was it's charging at 18 amper which is 3 times higher than the fast chargers. Bearing in mind people are doing this during the ride which brought to my mind is it really safe to do parallel connection of additional battery.charging the main battery at 18 a power and at the same time people are using the discharging during the ride i guess it's not really a good idea. Battery can easily heat up, even the charging port cable(the XT60 is strong up to 60amper) but the cable itself is quite thin awg18 or 20 I guess.
Hi
ReplyDeletefoot healing well, already been out scooting since sunday (gently at first, still gentle).
I have no direct experience but everything suggests its not ideal. I would say that:
* there is almost never a time when I want more than the 13Ah of my 2019 WW
* the charging port is not the best place to run that (think about the Amps out VS the Amps in and ask yourself "how will I get the Amps to flow that way when there is such a small potential difference (charger = 55V Aux-battery = 51V). You could do this with a DC-DC converter in theory, check prices while seated.
* better to run both in parallel (which brings a host of other issues
I know when I started I wanted to do long trips, then after I did a few I felt like "why the fuck do I want to stand here for hours?"
Remember the WW did this trip too ...
