Zero Motorcycles Forum | 2013+ / Re: How old is your zero?
« on: May 27, 2024, 10:08:54 AM »
That's a lot of miles, and a lot per year. How many other parts have you gone through, like belts, brake rotors? You're regularly only using 40-50% of your battery, have you had many times when you've needed to use more or do you think you could have coped with a 7.2 model all this time (although of course having less power as it wouldn't have been an R model)?

Also if you're going off the number of cycles shown in the app then I don't think it means full charge cycles (0-100%), I don't think anyone knows for sure what it means. At most you'd get what, 140 miles to a full charge? So you'd be looking at over 400 cycles for 60k miles.

I only mentioned components that failed as the OP was wondering about reliability, not consumption of expendable consumables.
But to answer your question, yes plenty of tires, belts, pads, & even a rear rotor. 
I should have mentioned that I’ve replaced the swingarm bearings (forgot the miles so guessing at 50k(ish) as they had become notchy.
Oh, I also had the front sprocket replaced as I blew it out attempting to get through a 10” or higher mud flow that I didn’t see (heavy rains in the local mountains heading into work at 0dark:30 one stormy morning)

As far as charge cycle count: it’s my understanding that it’s the amount of times the charger has been able (in my case enabled via timer) to obtain 100% or very near it.
As I limit my typical SOC I’ve only charged this battery to full (or close to it) only 12 times in 3 years/33k(+-)  miles.

In theory a 7.2 battery may have been able to get away with that size but at the time I purchased (used) 6.5 was the smaller battery & that provided wouldn’t work & would wear out much sooner having to use practical all the capacity every day. 
Besides, I justified the elevated cost (compared to ICE) by being able to charge at work for the lions share of my needs (that strategy changed when the original battery wore out).

DSR
2016
Took ownership in 2017 with about 2.8 k miles on the clock.
Now approaching 150k km (92,512 miles)
One deer kill to its credit
Charge port & On Board charger changed under warranty   
Battery replaced just before 5th yr (warranty) with just under 60k miles
Not sure how the original owner kept the battery SOC but with the original battery I would charge to 100% at work & return the next work day with as little as 12%  SOC left.
After the battery replacement I cobbled together a combination electronic & mechanical timer(s) to allow precise SOC level to obtain a max SOC of 70 & typically only using between 70~30% of the batteries level.
So far, so good with over 30 k miles on the new 14.4 battery & just now @ 69% SOC the cell balance is 5mv & # of cycles (charge to 100%) is 12.

Why not just swap out the stock flasher for a solid state (electronic) type?
You may have to swap the bikes flasher relay socket wires or source the oddball relay as in my case, Zero used an oddball relay pin arrangement.

Maybe that the reason that my Power Tank hasn't given me much of a problem. It is the same battery design as the ones in my basic pack. My bike was manufactured (in November 2017) right before the battery pack capacity was slightly increased - as I recall.

Out of curiosity & to add perspective, how many miles on this now +5.5 yr arrangement?

5
When you say that you only charge to 100% when needed do you mean that every time it needs to be charged you let it charge to 100% or that you only charge to 100% when you need full capacity to get to your destination. 
I suspect the former & would suggest to not charge to 100% unless needed. 
I try to maintain 30/70 battery level after the original battery was replaced (warranty) @ nearly 60k miles. 
The replacement battery has over 30k miles & still in good shape.

Is what my lightly used (1yr/2.8k miles) 2016 DSR came with. 
Nearly 7 yrs & over 90k miles their still hanging in there but I’ve had to repair & re-enforce quite a bit (but I’m hard on things).

why not alcohol?  It's waste gasses are not too bad.  The whole CO2 BS needs to go away.  I can get the not wanting hydrocarbons because of the nox and sox but CO2 is a given for even you being alive.

What if they had a barge, a large ocean going one, it had a lower profile, hauled stuff, it's entire deck top was solar panels.  Morning time, it charged up a little bit at night using wave action, to lift an anchor, then used the panels to push a motor on a propeller to drive it towards whichever destination it was heading.  when night came, it dropped anchor to sit where it ended up at, unless the prevailing winds would ultimately push it towards it's end destination even further, at which time it'd just keep drifting naturally..  While sitting it could use wave generators to make electricity by the up and down on the waves to charge a battery.  come next day, do it all over again,  during bad weather / cloudy days, it'd just charge it's battery, you could put wind generators on it too, not stupid tall ones but smaller ones along the deck to gather any wind that might be going too.  Perhaps every 10 miles or so you could have a small platform it could anchor / moor to, like stopping points, or every 50 miles, whatever works, if needed or for emergency docking.   have enough of these on a planned route to put these barges between countries on planned shipping routes.  You could have enough of them running that if it took a few days more to get somewhere, no big deal.  It'd essentially burn zero fuel except what it made on it's own.

when it gets wherever, unload, put new stuff to go back and send it back.  put a few dozen people on it, or even just a few with some rockets to fight off pirates, a keg of beer, some weed, a box of doritos, and you are good to go !  Throw in a fishing pole and they are loyal to the end!  Catch dinner, and perhaps some extra fish to sell when they get back in port, a bit of a trip bonus!

Hell sign me up, Ill be the first one to test pilot the HMS UnicornPhart.

Since we’ve entered the silly zone I’ll propose good old fashion teleportation as a means of future transportation.

still putting way more energy into it than they ever would recover back when converting back to electricity.  Not to mention the inherent danger.  Everyone cries when a lithium battery turns into a blow torch, what do they think a hydrogen tank is going to when it's breached?

Aaron

I think you have to realize that certain massive vehicles (trains, jumbo jets, cargo hauling boats, etc.) will need to run on green hydrogen & that (green) hydrogen will have to come from somewhere. 
Im guessing that ultimately the price of green hydrogen will be high enough to justify producing it via off peak electricity periods.

……………

Hydro storage only works because it does the same thing with a BILLION times more weight, and even then, it's incredibly inefficient and only suitable for conserving small amounts in situations where there is massive overproduction.

Green Hydrogen production (via Electrolysis) could take advantage of such over production periods.  This would yield a necessary commodity.

LADWP is planning on producing Hydrogen via Electrolysis from recycled waste water.

Another one was pumping water up into a storage shed of some sorts, whether it was a lake, a levy or just a high towar, then when needed let the water out to run a turbine.  Not the most efficient ways to store energy, but I guess would work in a pinch.  But one has to ask, can't the energy be used in better ways?

Why not a cold bank, freeze bricks, and then say a big refrigeration plant, for storing meat or something, run fluid thru the cold bricks to get cold, th en the walls of the freezer to keep the stuff cold at night, while the sun recharges it during the day with solar powering the reefers to re cool it.  But what about those drizzly weeks we get/

The biggest question is how much does all this cost?  Especially compared to just using electricity, or getting a regular battery or supercap.  ROI on life cycles type thing?

All this stuff sounds cool but is it feasable? Global warming is BS just like the Carbon crap is but they will never stop using it to separate fools from their money.

Im selling you a house, and you MUST have this poofty stuff on it. It WILL cost you an extra 100k, but don't worry! You can finance it with your house and it's only an extra 200 a month... for 30 years.  you can't always pass on the price of your dreams to your customers.

Aaron

LADWP has been using water storage peak demand generators for more then half a century

https://en.wikipedia.org/wiki/Castaic_Power_Plant

A few decades ago large building/facility thermal storage was a thing (chill or freeze large quantities of water during off peak energy to be used for cooling during peak energy periods) but I think it fell out out favor due to operational issues outweighing savings.

Zero Motorcycles Forum | 2013+ / Re: Living with error codes, 2021 S
« on: February 25, 2024, 09:28:39 AM »

More recently I have seen the same fault codes come back (0020 & 0028) after riding in heavier rain, but they seem to go away after a time, presumably after drying out. Has anyone else ended up just deciding to live with intermittent fault codes?

My 2016 DSR experienced fault code 20 & 28 as well as red triangle/green LED flashing during rain events  & I finally traced it down to the enabling circuit (ignition equivalent in ICE vehicles) getting wet & allowing a path to ground.
After insulating the defect, I’ve been trouble free for about a year & 7+k miles.

12
I’ve put about 85k miles on my iPhone X (Zero DSR) so not too worried about the 15.
I don’t know if I have the patience to deal with a second phone twice a day for my commute. 

I’ll try out the concept.

13
I went ahead & ordered the Ram mount Quick Grip.
The Quadlock looks interesting but I’m not sure I wanted a proprietary case that is an unknown commodity.
This option would be best assessed in person. 

I wasn’t impressed with the Ram X-Grip but the Quick Grip looks to be what I was looking for.

Thx all

A few years ago when a deer decided to commit suicide in front of me, I obliged & rode through the debris field.
Fortunately it was a young buck & my speed was down so I was able to keep upright. 
When I assessed my situation I found I was mostly ok but my phone had decided to leave its mount. Another good fortune was that when I circled back I found that the phone had survived quite well.

Here’s the mount….
https://www.revzilla.com/motorcycle/techmount-techgripper-handlebar-mount-kit

When the iPhone 15 came out with auto 911 summons my wife insisted I give up my trusty old  10 for the 15.
Fast  forward to today on the way home in the poring rain I happen to look down at my phone & all kinds of activities going on.
Apparently the phone had slipped down in the side pinching mount & managed to double press two opposing side buttons & call 911 (a selectable feature).
Anyway, two strikes & it’s out. 

Anyone have a handlebar mounted holder that’s easy to use yet secure.
Not looking/needing vibration resistance as it’s for my 2016 DSR.

TIA

A screwed clamp connection is what I would recommend for high amps. 
Crimped is fine for lower amps (less then 7.5a)
