Is anybody missing the fact that the dash doesn't give much info, other than the speed and batt charge??
it would be nice to see:
-regen levels being produced (0-100%)
-average and instant power output
-calculated range
 ect...
Any thoughts?

[CliC]

I'd like to see more info, too. Zero OEM'd a generic gauge cluster probably to save development time and perhaps cost. Adding an info display is a hacking project I'd like to undertake sometime.

[Larry295]

Exactly. Since it's electric and computerized, the whole point would be to have loads of data. Even something communicating with your phone to tell you the state of charge (like on some cars) ect...

[Doctorbass]

I have solved that display problem.

Now i have  these info on another LCD screen ( the Cycle Analyst V3.0 ) that i installed.

real time :
-KiloWatt
-Volts
-Amp
-Amphour used
-whathour used
-Speed
-max speed
-Avg speed
-Wh per km ( efficiency )
-Motor temperature
-trip dist
-regen Ah

Stats:
-total km
-Total Ah
-Total cycles

I also have installed the CycleAnalogger wich is a GPS datalogger that record at a rate up to 10hz  in real time all these data including the GPS info and put it into a lilttle micro SD card


That tool is a real MUST !! at 150$ a piece it's the best accessory you can install on an electric motorcycle.

Some of the TTXGP guys also use it.

i have 5 electric bike and all have that tool.

where do you find more info on this the Cycle Analyst V3.0
Sounds interesting

[Electric Cowboy]

Doc, do you have photos of you cycle analyst set up? How do you have it integrated with the controller?

I will post picture once it's finished.

I installed a 0.25 miliohm shunt in serie with the Main negative right between the battery anc the controller input. It sense the current and send the info to the cycle analyst S+ and S- input. I connected the cycle analyst power input ( same for voltage sense) to the input of the DC-Dc. It is fused and is already close to the Cycle analyst so it's safer than having a long line from the battery to the cycle analyst. ( Everything that connect to the power of the battery is fused (i used a 1A for any signal wire)

then the speed signal that i pick from the optical sensor on the motor shaft. It is supplyed by 0-5V and send pulse on a third wire that vary from 0 to 3V for each turn.

But the problem i have now is that the speed reading on the Cycle anlayst is not linear and constant... i have no reading for speed between0 to 20kmh and if i try calibrating it with the right pole count and wheel diameter to get the equivalent speed of the zero gauge, it is just not linear and i get false reading. The cycle analyst input is specified to be acepting any input from 0-5V or 0-12V or ground to open ( probably a pull up resistor that do the rest).. but for 0-3V it just dont perfectly work.

Everything else  is ok. i'll also connect the motor temp signal to the C-A.

I am also considering to modify the throttle signal type of the zero from 0-5K to 0-5V to match with the ebike cruise control that i plan to install and also to be able to have the throttle managed by the cycle analyst with the new V3 features.


I can say that it is really interesting to have the real time curent reading on the C-A while riding on the zero

I see that the current is limited according to speed. at low speed ( below 60kmh) the current never reach above 300A from what i have recorded...

that might change soon

That zero can take 400A from a dead start... and i'll enable that soon

I wold also post video of the C-A while rifding to give a taste of the power at different condition of use.

here is the start of my gauge :

[Larry295]

yeah but that's a majorly custom thing. Not something everybody can put on their bikes...

[Doctorbass]

Here is the data that the Cycle Analyst is displaying  (i bought from ebikes.ca)



Distance: 44.9km
Energy consumed: 2609.9Wh
Capacity consumed: 50.1Ah    ( out of the 70Ah total)
Efficiency:   56.1Wh per km
max amp peak: 558.3A
V min: 45.3
Average speed: 49km/h
Max speed: 108km/h
Power at that speed: 9kW
Running time 57.02min
V after the ride: 49.7V
V at begining of the ride 58.1V( full charged  and balanced)

The average current draw i saw was oscillating between 50 and 80A

Type of road: (50% on highway )
My weight 155 pounds
My tall: 5"9


Next ride i'll connect the GPSdatalogger option on it so i'll datalog all these data and their associated electrical parameters.

Here is something cool I did last year with GPS. It plugs into the google earth system and plays out live or replay data from the bike.
Mind you this was not done with the technology I am putting on my bike now, so there were some latency issues with the data pings to the server as you will see.

I was clearly into tron at the time

Here is a similar version that I did using google maps instead.

And here is one that does not follow the bike, instead it lets you follow as you see fit, so you can click on each of the data points and get more information.

yeah but that's a majorly custom thing. Not something everybody can put on their bikes...

Thankfully not so. When I am done it will be as simple as securing it to the bike and pluging it in I grew up plugging in the cable TV and hooking up the VCR because it was too complicated for my parents back then so now, I try to make things that even my grandma could use with a very few directions.

Here is my thread about the Cycle Analyst install i posted on Endless-sphere.

Pretty nice, I gotta admit.
But definitely something you need to have knowledge to install/set-up ect...
Hopefully Zero will come up with something of that nature pretty soon...

[trikester]

I'll add my 2 cents here by agreeing that we need much more real time data while riding and of course a data logger is also great for analysis after the ride.

If I couldn't have it all i would love to just have a bi-directional gauge that would tell me when current is flowing out of the battery and when it's flowing back in, from regen. In dirt riding, in ECO mode, I'm going back and forth between those two conditions and would like to know what's happening.

BTW - Just about to spend my week in the Klamath National Forest doing those big fire-road climbs, I posted about. Recharging at a lodge off the grid. Going to be interesting to learn how much total charge I can expend going up and how much I need to save for the return. There will always be some "ups" on the way back down.
