Real life consumption
« on: October 30, 2018, 02:05:10 PM »

For my Zero DS 2013 12,5kW with handprotectors, standard Zero screen and Zero bags and Zero Givi topcase.
I'm 1,83 m (72 inch) and 85 kg (187lbs).

So with 12,5kW battery:

50 km/h (31 mi/h)
1kW = 20    km (12,4 mi)
1V    =   9,2 km (   5,7 mi)
1%    =   2,2 km (   1,4 mi)

80 km/h (50 mi/h)
1kW = 14,5 km (   9    mi)
1V    =    6,7 km (  4,1 mi)
1%    =    1,6 km (  1    mi)

100 km/h (62 mi/h)
1kW =  10    km (  6,2 mi)
1V    =    4,6 km (  2,8 mi)
1%    =    1,1 km (  0,7 mi)

120 km/h (75 mi/h)
1kW =    7,3 km (  4,5 mi)
1V    =    3,3 km (  2,1 mi)
1%    =    0,8 km (  0,5 mi)

Nice data.  I assume that you mean kWh where you have typed kW. 

I have a general idea of the consumption on my FXS just from watching the dash, but not as precise as what you have written.  Do you have a tool that you use to track this?  Have you gone out at steady speeds just for the purposes of measuring?

Yes, nice data.
I have the same question as domingo3. I have tried to get the same kind of data in order to know if my windscreen had some influence on the range but it is quite difficult to
- find a flat road, without wind, where you can ride at the requested speeds without being disturbed by the traffic. The ideal would be a ring!
- measure the electric power used by the engine. It can be done with the Zero Voltage app, but it is the instantaneous power, and it is fluctuating... An app that would simultaneously record the speed and the power would be a great help. I have tried the "Metrics for Zero" app, but it does not seem to work with my bike.

I have put your data on a graph, and also some other data of the same kind recorded by Stephane Melançon. You should be interested by these other data if you do not know them. See attached screen copy.

I can just give very averaged data for my Zero FXS 2016 11kW 6.5kWh, and for the average use of the bike:
8783 kms and 445 kWh used, in a mixed urban/countryside use:
1 kWh = 19.7 km (12.3 mi)
If I consider that there are 5.7 kWh available (nominal capacity according to Zero specs) in my 6.5 kWh pack:
1% = 1.1 km = 0.7 mi
My bike has presently handprotectors, MRA screen, Givi topcase, side bags (picture), but I think it does not impact a lot on the consumption.
I am 1.70 m and 68 kg (much more with all the equipment !)

I ride every day commute 150km total.
This is what I have been registering every day.

Same public charger at work wich I can see on internet.
At home kWh meter.
I note myself the km's traveled and percentage and Volts used.
Done this for 20k km's and so this is not theoratically, this is my usage in real life doing an AVERAGE at these speeds in different temperatures, wind and so on.

So, for the general public this is a nice indication.
And for me personaly it's spot on.

For me it's great to know at my driving style:

at least I can do:
1kWh = 9 km
1V = 4,5 km

1% = 1km

Very nice to know when almost out of "juice".

I think some of your data is incorrect :P

https://www.quora.com/When-you-double-the-horse-power-why-don%E2%80%99t-you-go-twice-as-fast

Sorry, but I can't help it.
Every (AVERAGE) speed noted is tested during lots of km's and this is the outcome.
I did not adjust it.

Could air density (temperature) be a factor?
I find that on my daily commute mileage is significantly effected by temperature.
I.E., Afternoon leg yields hgher mileage then Morning.

I ride a DS 2017, after 1 year I get a 5,5 Wh/km consumption on the screen in a combined use. However, most of my commute is at a speed over 100 km/h. It has handprotectors, high Zero screen and topcase (+90 kg :D).

In any case I don't know if the bike takes into account charging losses or the energy lost when not in use. I don't know if these losses are material either.

My major concern is related to what is best to extend the life of batteries since I have found different opinions related to different manufacturers and models. Shall we fully charge the bike every day or just charge only up to a certain percent, say 80% (assuming you don't need a full charge for commuting)? What do you normally do?

I use my full capacity 1 way commute (75km) going 100-128km/h (128 will not get my engine overheated ;-)  ).

I believe Zero and Diginow states stopping at 80% is perfect.
Long storage (>1 month) at 60%.
But..... does any1 really allready noted battery degredation?
Not me so far.

5,5 Wh/km is not possible !

I'm at 9Wh/km on Zero app
5,5Wh/km is like allways go 50-80km/h, so not really realistic.

In that case, you can throw away your Zero App.
It seems that your bike has 12.5 kWh capacity, i.e. 12500 Wh
At 9 Wh/km you should ride more than 1300 kms without charging  :)

You're right it's 5,5 kWh/100km or 55 Wh/km.

Thanks. My commute normally consumes 25% (50% a day) and usually charge it at the office. Therefore, if I charge up to 80% at the office I would start the day around 55% which drops to 30% when get to the office. From what you said, I understand that leaving capacity below 60% isn't good only if > 1 month so 1/2 days shouldn't be an issue?

I am not familiar with how the bike computes consumption, as I said I don't know if it takes charging losses into account or the energy lost while the bike is unused, possibly is not material but I don't know. Do you know if the app computes something else? it seems that the app only retrieves data in real time (doesn't store data if not connected to the bike or at least it is not shown) so I only use it to update firmware or change configuration, that is why I thought that the average consumption in the on-board system was more reliable...

Average speed could be below 100km/h because the urban part of the trip and traffic but most of the time I ride over 100 km/h, do you think it is too low? maybe if we add losses we get closer to your figures.
