I plan on installing a cycle analyzer so I can better track watt usage real time and know what makes a difference.

I think speed makes more of a difference than temperature for me so far. Going to work with the temperature at 45 at 65-70 mph leaves me with ~56% pack left. If I travel at a flat 60mph in same weather conditions I can arrive with ~68%

My bike is geared for speed if I recall and it is running a size six controller without any fairings and the addition of a topcase on my rear seat.

Currently I run in sport mode as Eco mode uses more energy on my bike as it was modified for racing. In the future I will add a real time regen modifier when I break down and get DVT and the time to add it.

How do you measure capacity then?

Here's what I'm doing: I'm recording battery capacity left (as reported by the bike) every day when I get home from work. Even though there are small daily variations (I stop at the store to pick up some milk and eggs, I go to lunch from work that day, traffic was heavy or light, etc.), it's a highly repeatable ride and the average should be very consistent. I started collecting data in the middle of June, graphed it up in Excel, and so far if anything the trend is upwards. I don't know if the battery capacity is actually increasing due to some sort of "wearing in" process (which seems unlikely), it's just random fluctuations in my data collection, or if it's the weather (which seems the most likely to me).

At any rate, over the years I should see a trend, and when that trend starts to dip, that will indicate my batteries are aging.

Assuming I don't move before then, of course.

My total battery capacity increased about 6% total going to about 45,000 miles then has held steady since then.  There is a strange break in capacity increase I can not explain but even the data sheets seem to indicate that up to about 250 full charge/discharge cycles at 1C charge/discharge, the capacity goes up.  For most of us, it will take longer than 250 cycles (perhaps 1000) as we don't full discharge to 100% DOD each time.  Partial discharge cycles down to 20% have minimal effect on break in/cycle life from what I can tell.  Keeping the battery about 20% or charging immediately when running close to empty will greatly increase cycle life.

There is a link to the datasheet in the first post here: http://endless-sphere.com/forums/viewtopic.php?f=31&t=51226

Here is a first try at collecting the easy data that people might find interesting.  I made a spreadsheet using google docs for everyone to share their riding miles and some other information.  If you don't want to fill out every column, I don't care, but I am most interested in total driven.  You can update this as often or infrequently as you like, but I think it will provide some interesting information. 

Go to this link and hopefully soon we'll have a decent idea of how far people have gone on their Zero!

Constructive feedback is welcome!  If there is other information you think would be interesting to gather in this manner, let me know.

20000!

[CrashCash]

Ugh. I'd joke about the 62,000 miles I have on my odo, but that's some sort of screwup from getting my BMS & wiring harness replaced. I actually have about 1500 on it, so I guess that's about 750 miles a month (jan/feb) and I put about 210 miles on it over Memorial day weekend.

My "range left" indication is hopelessly confused and now just wobbles between 74 and 83 miles, no matter the charge state or how I'm riding.

20000!

Awesome!  Way to go!  Are you going to Pike's Peak this year?

[evdjerome]

Hit 20000 on the way into work today!

Well for the DS 2010 so far it has done a whopping 1486 miles.  I have spent over a week trying to get really basic parts for it (Carbon brushes) without success to date.  I don't think it will be clocking up any additional miles soon. it has managed about 8 miles this year but then I had to push it when it died for 3 km of that. 

The bike cost my brother new, $13,590 here in 2010.  Cost about $9 / mile to run so far.  Asked about trade ins with the Zero dealers here in Australia.  They don't want to touch it and will so far offer nothing for it.  They can't as yet provide parts for it (Manny at Zero in the USA is trying really hard to help with this)... I can't take it anywhere willing to work on it. I am left now that as yet I can't get the parts for it, can't fix it, can't get it serviced anywhere, can't trade it in, not worth more than scrap to sell right now, even working the Zero dealers don't want it.  Not good Zero, on a bike that is less than 5 years old (Will turn 5 in Nov, first rego, that cost about 14K to get it on the road and no rebates)....

I have had the argument thrown at me, that spending 2-3 K on a new motor would be a great investment.  Since petrol bikes would have spent that much after 5 years.  That is fine, except I don't want to spend 2 k every 1500 miles to keep it going!!!  Most other bikes after 5 years would have done more than 1500 miles too.

Had the exact same thing. Went into the dealer with 640km on it to get a faulty MBB swapped. Came back showing 118,000km - didn't notice until I got home. Gave the dealer a call, they lined up a time with Zero and then stopped by on the way to work this morning and they corrected it while I waited.

This week I went over the 46.000 KM which is 28583 Miles
I drive My DS ZF11.4  2013 all year round and it is still doing well.

I come from the Netherlands and filled in the overview.

[benswing]

Wow, that's a lot of kilometers (and miles)!  Thanks for adding your name and info.
