34% better combined,
Or a whopping 45% better in the city!!

** 45% **


Nick -

That is EPA mileage " testing" - they don't actually drive the cars on the road. EPA testing is way off for most cars, and especially for hybrids.


In Consumer Reports magazine ( October 05 issue) they show mileage test results ( actual driving results) for different cars, including - for mixed city and highway driving -

Prius : 44 mpg overall   ( 11 mpg less than EPA estimate)

Echo : 38 mpg overall  ( 2 MPG better than EPA estimate)


So, according to actual testing, the Prius gets 16 % better fuel mileage then the Echo. This almost exactly matches the numbers claimed by me and Joel in the previous couple of posts ( 17%) based on real driving experience from people on this list.

Consumer reports is a non-profit organization that accepts no advertising - I have faith in their testing results - they have no ax to grind.

They also show ( in another chart in the same article) that the EPA prediction for the Honda Civic Hybrid is 48 MPG city , and their actual testing showed 26 MP city . In this case the EPA prediction is 85% higher than the actual value. This is inexcusable.

One of the reason for the current hybrid popularity is the inflated EPA numbers for them. EPA needs to clean up their act. People should know the real performance of all cars so that they can choose based on honest data.

Actually AGM batteries are VERY tollerant of high charging currents.  I
doubt your lester charger would hurt them at all.  In many cases chargers
are not able to keep up with AGMs in providing the charge in the same manner
they were discharged.  If you want a new one I would recommend a ZIVAN
programmable one.  That way you can change the charge curve according to the
pack you have.

Subject: Cold storage of Batteries


I live in Central NY State where during the winter months the ambient air
temp rarely gets above zero degrees F.
I store my EV from mid November until mid April. What are the proper methods
of charging the batteries or protecting the batteries from freezing during
this long term storage?  The garage the EV in is not heated.  I'm using 16
six volt lead acid batteries in my EV. What special attention do the
batteries require during long term cold storage?

Also, I may be shopping for a new charger. Nothing fancy. Something that
will charge 96-120 VDC traction pack and is able to accommodate AGM
batteries as well as "traditional" or "standard" 6/8/12VDC batteries. Any
recommendations? I have three 30 year old Lester chargers. What is the
general opinion of Lester chargers?  I believe my Lester chargers would
severely damage AGM batteries. Is this true?

Enjoy your turkey!

Well a load test revealed that the majority of my
batteries are just fine.  There is, however, a stinker
at the end, and I don't like boiling off active
material for the sake of bringing up one battery who's
SG just won't come up (seems to be stuck at 1.245).
Option 1:  Go back to Interstate, and swap,
excercising a pro-rata.
Option 2: EQ again, this time using the distilled
water treatment (remove some acid, charge, replace the
acid).
Option 3: Charge it outside of the rest of the pack. 
Anyone know a real good charger manufacturer for 8V
batteries?  (Obviously the PFC-20 could do 2 at a time
in series, just not one...)
Thanks,

"Is your flywheel neutral balanced or does it have any balance weights
on it?  What's the imbalance of it?"

It isn't about the imbalance, its about getting the flywheel to attach
to the adapter hub.  The V6 flywheel uses 6 M10.9 17 mm fine thread
bolts torqued to 50 ft-lb.  The adapter hub is tapped for 6 3/8-16 UNC
bolts.  I was looking for confirmation that the 2.5L flywheel uses
those bolts - it doesn't seem right.  I knew they used the same clutch,
and was wondering if the flywheel was the same, too (at least if the
connection was the same).

Granted, a 3/8 coarse thread bolt will fit in the hole, but there will
be more slop with those than with the proper bolt.  The head of the 3/8
bolt is taller, too.

As far as emissions vs gas mileage, if you are concerned about green-house gases, the CO2 (the dominant green house gas) that a car produces is exactly proportional to its fuel usage. There is no magic that hybrids can do to change that. So, the Prius produces 17% less CO2. Not a HUGE difference.


I was about to respond to Phil and say there is a huge difference in respect to large units of vehicles. But just for grins I ran some numbers. As of September Toyota sold 72,000 Prius' in the US in 2005. They will probably exceed 100,000 cars in 2005 like they did in 2004. I think total worldwide sales to date are well over a 1/4 million.

The Prius emits 104 grams/km of CO2. The average car produces 198 grams/km. Toyota Echo, 117 grams/km. Just for fun the Hummer H2 produces a whopping 432 grams/km of CO2. Choke me baby.

For 100,000 cars that equates to about

11.46 tons of CO2 - Prius
12.89 tons of CO2 - Echo
21.85 tons of CO2 - Average Car
47.61 tons of CO2 - Hummer H2

Your mileage may vary and I'm NOT a professional number cruncher.

Thanks for the data, Chip.  My take on this is that :

1. The advantage emissions-wise of the Prius over another modern, high mileage car ( like the Echo - my family owns three of them) is relatively small ; 12.5% by your numbers.

2. But, if large numbers of Prius are bought by people who would otherwise drive cars like the Average Car in you list ( or, even better yet, Hummers) , that would be a great benefit.

Phil


Hi Phil,

Yep, I pretty much drew the same conclusion after running these numbers. There isn't that much difference between the fuel sippers like the Echo and the Prius. But if people trade in their average car for a Prius, in large numbers, there could be a significant change in emissions and gas savings. I'm sure Toyota will exceed well over 100,000 cars in 2005. I thought I heard Toyota planned to ramp up production to 140,000 units for the US this year. That really helps. It's a step in the right direction. We plan to buy a Prius in 2006 and just started actively looking.

What's also interesting to think about is we need 4 Prius' to offset the emissions from one Hummer and looking at the ratio of Prius sales to Hummers. It's about 4 to 1. Hummer sales seem to average between 2500 and 4000 per month. But I'm sure US demand will increase that ratio even more.

My wife has an 04' prius. I'd love for it to be plug in with a larger pack 
because most of the drives it does on are very very short so we would use 
almost no gas. 800mpg could be possible ;-) Is there a proper description of 
that yet? Maybe 800mpg with 45kwh plug in power.
 
We just can't take my electric truck because it just got done with it's commute 
and needs juice. Plus it is a piece of junk with no a/c no real heat and a 
laundry list of other problems and I swear it has flood damage from before I 
got it. Don't get me wrong it has always gotten me where I was going and only 
once gave me a scare because the batteries were really really cold and I wasn't 
thinking. Once I'm done with my EV Motorcycle I may take a crack and fixing all 
it's non EV issues.
 
Now in regards to mileage all I can say is somehow my wife gets 41mpg in the 
04' prius. When I drive through the same routes for a whole tank I get 57+ 
without even looking at the gauges or anything just driving with traffic. She 
used to get much better mileage in the '01 we had but maybe back then she was 
trying.

My wife and I get the exact same mileage difference in our 04 prius.  She's a
leadfoot.

If the battery\plug-in option ever becomes available, I will sure try to find
the bucks to buy it.

This seems like a salient point here.  When you buy a vehicle you are
in a sense "voting" with your money.  Maybe the Prius doesn't have
the "extreme ultimate" solution, but is it going in a direction that
you agree with?  If so, and you have the money, buy one.

The way to support this direction in technology/manufacturing is to
purchase now and promote it to others.  Sure, you may spend more
money but that's how these things work.  Higher quantities mean more
R&D, more parts manufacturers, and eventually price reductions and a
wider variety of the batteries and components that we (EV'ers) enjoy
so much.

Just me thinking...

A BC-20 charger, without the boost transformer, says it can handle up to a
108V PbA pack.  At 2.5 volts per cell, this comes to 135V.  I was wondering
for my TS pack, which totals to 148.75V, if I configured the BC-20, still
without transformer, for 120V, would the charger start out at full amperage
when the pack was low, then taper off to a lower amperage as the pack went
from the 135V to 148.75V range?  

For the TS cells, ideally I'd like to start out charging at the full 20A,
but then switch to 2A when the first cell reaches 4.25V.  If the BC-20 would
automatically taper down as the pack approached 148.75V, however, I think
would work also.

Mr. Merz,

Consider these points:

1] In the era 50 years ago of very cheap oil and big cars,
    VW found a nitche and succeeded.
2] 25 years ago, every auto maker demonized Ethanol as
    as an engine destorying fuel even as an additive, but
    now Ford touts that it will make 250,000 E85 vehicles
    in 2006.
3] It will probably take any major automaker atleast 10 years
    to stop milking the oil/hydrogen/government subsidy cash
    cow and gear up any practical EV program, if ever....
4] Lastly they will surely follow the pattern repeated by the
    original Corbin Sparrow and ignore the hard learned wisdom
    of the folks on this EV list and create an overpriced, over-
    engineered EV Edsel.

    Individuals like Jerry Dycus with the support of numerous
    list members are making the EV a reality and with the
    need for and the existing vacuum the only failure is the
    lack of doing. IMHO

Actually AGM batteries are very tolerant of high charging currents right up to a point. Once you pass that point (14.x volts per 12 volt battery) you really should drop your charge rate below the recombiner rate or you will vent the battery.

Currently I recommend charging at moderate rates, slow-charging from 80% to full, and using regen for that every once in a while 30kw spike charge.

I have a Continental Grand Prix tire on my racing bike that has a max inflation 
pressure of 175 pounds.  It is rock-hard when inflated to that pressure and has 
almost zero rolling resistance.  It also has a very small band of rubber around 
the center of the tire, which is what actually makes contact with the road.

I reviewed Brandt's book last night and he states that more inflation is better 
- rockhard is good if you can stand the ride and handling doesn't suffer.

While I can't say for motorcycle tires, bicycle tires (at least the good
ones) are NOT stiff.  In fact the really good ones you can fold up and
stick in a pocket or seat bag.

They might be hard when inflated, but the tire itself is not hard.

Has anyone tried vortex generators and/or strakes on their EV to produce
an "aerodynamic boattail" to reduce drag from the rear of the vehicle? 
If so, what do you estimate the improvement in efficiency to be?

Thanks,

Fully charge the batteries before storage.  If possible recharge in mid
February.  Charge again before use in April.  Charged batteries will not
freeze at any temperature you will see in central NY.  As batteries lose
charge while sitting, a charge mid winter would certainly help.
According to the Trojan website, flooded batteries at 100% charge will
freeze at -92F, with 85% charge -62F, 62% charge, -16F and at 20% charge
only +19F .  Obviously it is important to keep them at 85% or more
charge when stored over the winter.  Similar chemistry works on AGMs as
well.

Subject: Cold storage of Batteries

I live in Central NY State where during the winter months the ambient
air temp rarely gets above zero degrees F.
I store my EV from mid November until mid April. What are the proper
methods of charging the batteries or protecting the batteries from
freezing during this long term storage?  The garage the EV in is not
heated.  I'm using 16 six volt lead acid batteries in my EV. What
special attention do the batteries require during long term cold
storage?

Also, I may be shopping for a new charger. Nothing fancy. Something that
will charge 96-120 VDC traction pack and is able to accommodate AGM
batteries as well as "traditional" or "standard" 6/8/12VDC batteries.
Any recommendations? I have three 30 year old Lester chargers. What is
the general opinion of Lester chargers?  I believe my Lester chargers
would severely damage AGM batteries. Is this true?

Enjoy your turkey!

Hello to Phil and All,

I know this is getting off topic, but the hybrid bashers, most who have not even owned or driven one, need to be corrected.

Nick -

That is EPA mileage " testing" - they don't actually drive the cars on the road. EPA testing is way off for most cars, and especially for hybrids.


Oh great...here we go again with this. Did you not read my post about this? Most 'everyone' I know who owns hybrids, get better mpg, not less, than the EPA ratings. My Honda was rated at 70 mpg. Go to Mike Chancey's EV Photo Album to see my Insight's dash reading of 92.5 mpg after 53 miles of driving! Friend Geoff Shepherd regularly gets 65-70 mpg in his '05 Prius. Where's the Echo that can even get close to this? Got some numbers for me? Take your Echo out, the car you think will hit within 17% of a hybrid, and do highway speeds of 55-65 mph up and over mild hills. Do this for 100 miles, and report back to us those 65+ mpg ratings you'll get.



In Consumer Reports magazine ( October 05 issue) they show mileage test results ( actual driving results) for different cars, including - for mixed city and highway driving -

Prius : 44 mpg overall   ( 11 mpg less than EPA estimate)

Echo : 38 mpg overall  ( 2 MPG better than EPA estimate)


You're using Consumer Reports magazine as a quality source? This discussion is getting more ridiculous. Consumer Reports has zero credibility in the automotive world....zero. They have enough trouble driving a toaster! Looks like they also have trouble driving a hybrid, too.


So, according to actual testing, the Prius gets 16 % better fuel mileage then the Echo.


No, according to the idiots at Consumer Reports.

This almost exactly matches the numbers claimed by me and Joel in the previous couple of posts ( 17%) based on real driving experience from people on this list....after, just with some hand-waving, arbitrarily mileage (from previous post)


I guess you just waved your hand and ignored my real driving experience as a person on this list? Can your Metros and Echos match an Insight's 85 mpg? Can they match the new gen Prius owners that can easily get 60+ mpg?


Consumer reports is a non-profit organization that accepts no advertising - I have faith in their testing results - they have no ax to grind.



Oh come on, wake up to these guys! No ax to grind? Maybe you're too young to remember their highly charged political bashing, their goofy tests that were proved wrong by real scientists, and their poor choices in cars. They picked the Pinto over a Datsun 510, you know, the Pinto that blew up when bumped a little too hard from behind, the car that had one of the poorest crash ratings of any car ever built, the car that accelerated 3 seconds slower to 60 than the Datsun that has a smaller motor! Where are all the Pintos now?....oh that's right, they all fell apart and are rusting heaps in scrap yards. Those 510's Consumer Reports rated lower than the Pinto? They're collectible and highly prized sedans that are still on the road, with huge groups of clubs based on the car. Consumer Reports really hit that one on the head, didn't they?

In 2000, the year I bought my Insight, if memory serves me correctly, Consumer Reports rated the Insight at 54 mpg! Go to Insight Central, if you don't believe me, and check to see the average mpg owners are getting....none of this goofy Consumer Reports crap, these are real people who actually know something about the car.


They also show ( in another chart in the same article) that the EPA prediction for the Honda Civic Hybrid is 48 MPG city , and their actual testing showed 26 MP city . In this case the EPA prediction is 85% higher than the actual value.


My wife and I test drove a new Hybrid Civic when they first came out, and over 30+ miles of in town city driving, averaged 45 mpg. Yes, that is a little lower than the EPA ratings, but I wasn't driving it easy at all, and there were three people in the car. I ran numerous full throttle acceleration tests, purposefully pulled Portland's steep hills, and ran the AC on and off. We got more than double what those morons at Consumer Reports got. How does any thinking person get 26 mpg in a Honda Civic Hybrid? What did they do, leave the E brake on? The fact that Consumer Reports only got 26 mpg should make you question their competency. Do you blindly accept that a Honda Civic Hybrid only gets 26 mpg in the city? Did you 'really' accept this as fact?


One of the reason for the current hybrid popularity is the inflated EPA numbers for them.


No, the reason is satisfied owners who get even better mpg numbers than the EPA said the car would, and, because people are interested in driving cleaner machines.

EPA needs to clean up their act.


Yeah, I agree. they should come clean and go public with the fact that they were too low in their mileage numbers for the Honda Insight, because 70 mpg is way too low compared to what the car actually returns.

Phil and Joel...how many friends do you have that actually own a hybrid? Ever spent time in one yourself? Let's add some credibility to this discussion and qualify ourselves. I 'have' driven the Echo, two times to be exact, and have spent more time behind the wheel of a Metro than I want to remember. How many Insights have you guys spent time with? Prius? Honda Civic Hybrid? Come on, fess up :-)

Hey, Phil and Joel, let's have some fun. Why don't the two of you pile into that hybrid-matching Echo, and take me on. Want to compare it to my Insight? I'll take a handicap and run the AC/defroster at full tilt, and run with two passengers and full luggage. You guys can cheat and leave the AC off and run with an empty cargo area. We'll hit the Oregon mountain passes, do some freeway driving, and to make it more interesting, let's make the deal that we have to travel at least 700 miles on a single tank of gas. My Insight with it's 10.6 gallon tank will definitely have gas left over after 700 miles. It would be fun acclerating up the steep inclines as the electric motor jams in the torque to effortlessly propel my Insight up the grades, knowing you guys were behind me struggling to keep up were wringing that unassisted gas motor out, revving it to near redline (and sucking gas). It also, would be fun knowing that as I went down the other side of said mountain slope, regenned, and stuffed power into my hybrid's battery pack, that you guys were instead, smoking the brake shoes and pads as you threw away power heating up your regen-less friction brakes :-)

Ready for this comparo? What's that you say....your Echo will run out of gas at the 400-450 mile marker?

See Ya....John Wayland

Satisfied hybrid owner getting way higher mpg than the EPA ratings

The headliner on my Jet Electrica has detached itself from the roof and
is hanging down in the center of the car.  Does anyone know of an easy
way to reattach it?

Thanks,

1.  You can stick thumbtacks (preferably plastic) thru
the cloth into the foam board.  Sometimes you can make
it into an interesting pattern.
2.  Tack marks of super glue thru the cloth.
3.  rip it out and use spray adhesive to reattach.

Dont try an iron, I had a big iron mark when it melted
thru.  And you would have to explain everytime someone
was in the car.

I had no intention of bashing hybrids and I'm sorry you took my simple
comment that way.

I made a simple statement of curiousity regarding data that was posted
to this list (48mpg) and data that agrees with that that I had seen at
a while ago at:

http://www.greenhybrid.com/compare/mileage/

I was deliberately only speaking of MPG and my comment said that, I
understand there are other considerations.

You claim those numbers are incorrect. I don't have a problem with that.

It was a simple comment on that hybrids were supposed to be
revolutionary and I personally (and I may be among rather few in this,
but that's ok) don't consider 35% to be revolutionary.

You are claiming like 80% or so, though, which I would have to agree
is excellent.

I just have to wait 5 more years until the used ones drop far enough
in price such that I can buy one :) Actually, by then I hope to have
an EV.

Thanks for the information and I hope you understand that I didn't
intend to "bash" anything--it was simply a curiousity statement
regarding some numbers. Unfortunately, apparently it was taken to be
inflammatory.

Best wishes,

-joel
