Installed kit from Plug in Supply getting 28 miles!

ok . . . . and there are a few Prius owners that get 80mpg . . . . and there are 4 or 5 Leaf owners that get 125 mile range. What does that have to do w/ the average Volt owner that gets 36 ev ... or the average Leaf owner that gets 80 miles ev. I'm just sayin' . . . it's great that you're in the upper 1/2 of 1% and all - but it still doesn't make an average. Your high ev range, simply mates with the poor slob that's only getting 28 miles and thus you get an average of 37/38 all together, right?

 

if you follow back the thread you'll see that John was replying to the OP who posted

So the OP was talking one-off for his 29mile EV (well below even the EPA of the Volt, misquoting the Volts MPG (which is 40 highyway, 37 combined). John was repling in kind. There is no EPA for the prius PHV + added pack, so no EPA-to-EPA comparisons can be made.

But your statement about the average has no basis in fact, and the suggestion that John is the upper 1/2 of 1% is even less supported by facts. There is NO data of which I am aware showing average Volt owners gets 36EV miles. Even the EPA testing got 50+ miles but, as they converted from 2 cycle to 5-cycle they discounted the the EV range by 30% to get the estimate (to account for varied losses). (Also note the EV range is also a function of Temp, Terrain and Technique, and so the average may be slightly skewed by those fair weather volts in Cali. ) The EPA does not have a good handle on how to measure/estimate for battery stuff, it has a very high variance and depends on lots of assumptions. They made a first cut (based mostly on data/process from Argonne National Lab).

While voltstats can tell us the median MPG is 179, it does not report the actual EV range. I'm not aware of any site that does.

 

Dang, I thought I had finally found a space where I could claim to be an over achiever.

 

Okay guys with Volts.. time to head back over to the voltchat.com website.. getting REALLY tired of the Volt / PiP pissing game. FYI, I just checked fuelly and I am seeing similar numbers to the PiP on MPG.. Those of you that are religious about charging are getting the higher numbers.. the average is showing about 90 to 100 mpg, which seems pretty consistent to the numbers for the PiP.

unfortunatly, Fuelly does not work when an entry is over 200 mpg, so not too many Volt owners bother with it.

It doesn't seem to be a limitation that affects Prius

Go ahead and try it.

The guys at Fuelly are trying to decide on how to best add electric fuel ups as well, but it doesn't seem to be a priority for them.

 

odd....i have looked for the VOLT several times on fuelly.....it still is not under chevy cars to this day, how are you guys finding it there?

thanks for link.

Well fuelly is not supporting PHEV's in any meaningful way. You can check out mine
DrInnovation's Volt (Chevrolet Volt) | Fuelly

And if you look it says 168MPG.. because it cannot handle my last two fill-up as it cannot handle 481MPG (april) or 436MPG (august). Fuelly presumes anything over 200MPG is an error and does not update with it. I'm sure my next fillup in Nov or Dec, will be the same. I write to them regularly and they don't seem to care. Fuelly is so useless for a Volt that almost no volt users keep it up to date -- the only ones that do are those that burn so much gas it can handel their limited data.

Not interested in a pi..ing game, but do want to keep the facts straight. If you go look at Voltstats.net, which is data automatically collected by the car (so not just the most dedicated users), its at 129MPG average, 179MPG median, with data on 16Million mile (i.e. way more data as well).

Some users will find the Pip ideal for them, and 80MPG is decent for a hybrid. Others will find the Volt allows them to use less gas. For me, only a Model S signature or roadster would let me use even less (and I'm not dropping 100K).

 

They took it off the "browse" after people complained that it is misleading since they don't compute properly for the Volt. Until the post here I presumed it was no longer a proper group.. (though I knew I could see my own car.. its still not updated properly).

 

drinnovation -- the point here is this thread is discussing the expansion of the PRIUS ev range.

 

And if you had posted to get back to the topic.. it would not have vered off topic so much.

The work Jim335 has done in expanding his plug-in prius to get 28 miles of EV, is interesting and to be applauded.
My only posts on this thread were answering questions about how heater worked on the Volt, and correcting mis-information others posted about the Volt.

If you don't want the volt discussed, then don't discuss it or if you do, then keep the facts straight.

 

a few threads back - after suggusting that flaws are likely in the various on-line range estimation sites ... you countered that the Volt site is 'accurate'. Now it sounds like you feel Fuelly IS accurate for Volt ... "if" Volt owners "burn through fuel". Therein lies the rub. "If" you want to show you get infinite range ... and your yearly drives lend them selves to that objective - you can show it. "If" you get crappy range, you can show that too. If you're embarrassed ... you don't have to post your consumption ... or maybe you just like your privacy, so you defeat the monitering - which skews real world averages.
Point is, it's gamed to some extent, because all users can't be forced to participate . I get super high range. 5miles per kWh @ the wall. Carwings shows some folks getting 3x that range ... that kind of efficiency posting simply means some folks want their recording to stand above the rest. But, unless the programs prevent gaming (ie everyone forced to display all variable data) there will continue to be inaccuracies .... and no one can accurately predict how small or large the deviation is.

I did NOT say Fuelly was accurate for the volt I said

Which is quite different. Some people that drive a lot, want to track the costs. That is something Voltstat does not do.. there is no easy way to add your cost per fillup into the system. So Fuelly is good for that. BUT, since it cannot compute MPG >200 and cannot track kWh its not overall the useful.. why bother to enter data that they system cannot use... so if you really want to track things you use your own data. The exception is if one's MPG is so low that fuelly can track it, in which case those users may find it useful. So the majority of fuelly volt user's would be those who get a benefit from it.. i.e. those with low overall MPG and lots of gas fillups to track.


I said voltstats is pretty accurate because it automatically collects data from lots and lots of cars and seems to measure accurately. the Volstat data been very accurate in my sampling (unlike carwings that apparently grossly underreports stuff -- and I'm unaware of a unified site with many people's carwings data.. if you know a link I'd love to have that). There are more volts on voltstats.net than any 2011-2013 model on fuelly.. by a wide margin. (There are nearly 2000 volts on the site.. or about 10% of all Volts on the road. There are not even 2000 Prius's on fuelly including all model years combined. )

That level of sampling, 10%, with automatic data collection (so no real cheating), is what makes it good. Yes you get a bit fo self-selection bias, but nothing compared to the bias of a site that makes you do work.. or makes you do work and then doesn't even report correct results.

Agree that "accurately predicting" the deviation from self-selection bias is hard.. However, since GM does track the overall average (all cars, its automatic) and report it from time to time (and has their ticker.. ) we get a general sense of the voltstat bias.. the drivers have, on average, a bias to have more EV miles., with 71% EV overal compared to 61% EV on the GM volt ticker (though we don't know how accurate that ticker is.. I've seen it go crazy from time to time).

@chesleyn sorry to take it off topic again.. but I'm answering a direct post directed at me on this thread.

 

Jim, any news on using OEM EVSE port for charging the extra battery pack?


iPhone ?

 

Any idea if PIS is planning to work on it? It seems like functionality they should be adding. I'm glad you are planning to work on it, but I'm a little disappointed to find out that it is not already part of the PIS kit. Especially when the pricing breakdown on their website seems to indicate that there was no need for an additional battery charger.

 

I see PluginConversions finally got their product up and advertised on their web site . . . . . looks great!
Gold Peak Plugs into Plug-In Conversions
.

 

That is a NIMH 6.1kWh pack for a regualr prius. Nice package but not designed for the PiP.

 

Ooops.

Just checking to see how things were going with your additional battery pack. Is your EV mile range still around 28 miles? Is the colder weather affecting anything performance wise? Do you think it was worth the cost?

Thanks!
