What kind of miles per gallon will you see on the EPA stickers of plug-in hybrids as they go out in the next few years? The miles per gallons for plug-in hybrids will be rated lower than traditional hybrids! Why? Unlike traditional hybrids to get the added miles per gallon from a plug-in hybrid you have to do something: plug it in. If you don't the un-used move of the battery is just dead charge and that means lower miles per gallon. Plug-in hybrids will probably leave part of the battery flat waiting for you to charge it. The car's software could fully charge the battery using regenerative braking but why would a driver go through the effort of plugging in the car if the battery measure was always topped off? A solution to this problem is an "I will not plug you in" button that tells the car to fully charge the battery and don't wait for the driver to plug it in. I don't think the major automakers ordain go for a software solution however. I think the first plug-in hybrids will just be better hybrids and get better mileage than traditional hybrids only because they have larger batteries. This will be regrettable because it means plug-in hybrids will hobble the development of traditional hybrids. Plug-in hybrids will only be the panacea we hope for if the auto makers. EPA and drivers get it right. We want to know what you think. If you were the EPA what would you put on the sticker for a plug-in hybrid? Would you put the highest possible mileage the lowest or an average based on plug-in hybrid use studies? If you were the car maker how would you measure the options? Would you make every hybrid you made a plug-in or market it as a high end option? As a consumer what's the minimum miles per gallons change magnitude would convince you to take the measure to plug in a car?
1. I've thought about this at times. How do you actually come up with mileage? My sugestion is to undergo two numbers. The first gives the range on electric only the second is the mileage you get when it goes into standard hybrid mode.
3. Why would you not plug in your series hybrid? The miles you jaunt on electricity are about 10 times cheaper than the ones you travel on gasoline. And plugging in at home in your own garage is much more pleasant than visiting a gas displace.
4. These are certainly questions that need to be answered. How to calulate MPG for plug ins is already a big questions for those conversion kit companies. Of course they claim the biggest MPG number they can based on EV driving only (and change surface with those numbers you'll still never get your $10-25K back). However for EPA ratings the gov't will decide how it's done not the car companies. I'd say act the tests as they are for hybrids (which requires the battery to be at the same express of charge at the beginning and end of test) and add a "Miles on EV only" number to it to show how far you can get by plugging it in. Otherwise it gets way too messy. On a separate note the title of this bind makes no sense and it is contradicted by the blogger in the article itself :"I think the first plug-in hybrids will just be better hybrids and get better mileage than traditional hybrids only because they have larger batteries." I agree with that statement. Some populate have added extra batteries to Priuses and those cars do get higher MPGs (even if you don't plug them in). By the way a Prius battery only weighs about 100lbs so doubling the capacity really doesn't add much weight. gratify change your title to reflect what is actually said in the article sincea) you have no proof that MPG numbers for PHEVs will be lower,b) that title is totally invalid anyway since nobody knows how MPGs will be calculated,c) the small amount of bear witness so far points the other way andd) you contradict yourself in the article
5. Perhaps we should ask what the gas mileage is if you don't put fuel in it. Then again perhaps this is a silly question. Any mileage evaluate is rife with caveats; this just seems desire another one. Just define a standard "profile" just as the EPA currently does today.
6. I don't understand what this article is trying to get out. "Fully change the batteries from regenerative braking?" come up maybe if you're NEVER going to use the electric mode and you're planning on driving a very long time. Otherwise there is no way that captured halt energy alone would contribute more than a tiny amount to the batteries.
7. Karkus. As I say in the article all things being equal if you don't plug it in you ordain get displace mileage with a plug-in hybrid vs a normal one. Automakers and the EPA will try to enclose it but it's really the back bone of the article. Yes the battery "only weighs" so much and doesn't add "that much charge" but it's more. Yes. I am being a bit provocative and playing the contrarian but my inspect for automakers turning hybrids intentionally mild and keeping plug-in as high end options is VERY possible. Every single effect of the plug-in hybrid can't be good can it?
8. attach. The Prius can rush the battery with the gas motor without the driver doing anything but I did not want to get into that too much. I don't evaluate GM does that at least with some of the mild stuff. The batteries on those hybrids are smaller too. Two mode might. I think. Volt uses an engine to charge the battery of course.. this is why I did not want to get into it :D
9. ABG really needs to get an editor to read articles before they are submitted this one is high on rhetoric light on facts and borderline incoherent. It reads like last nights bar conversation about hybrids. The sensible way to preserve mileage is:Battery range: 20 miles. furnish econ (battery neutral): 38mpg/42mpg. It is absolutely pointless to get to get into the bullshit bet of combining plug in energy and gas and calling it MPG. Plug in every 20 miles and MPG is infinite. Or dream up any plug in interval to match up with any MPG you be. This is a pointless apply in bullshit. MPG has to be quoted in the battery neutral condition. Anyway lame blog post that is barely average quality for a forum posting.
10. Traditional hybrids increase efficiency which just means that we destroy less gas. They are a good first step in making the oil that we have last longer but any fool can see that oil is limited and literally everything we undergo depends on it! We must rid ourselves of this addiction and embrace multiple and diverse renewable energy sources as society is in jeopardy. Electrification is the only way to fully embrace energy diversification and plug-in hybrids are the next evolutionary step along the way to full vehicular electrification. The problems with electrification include (1) generating costs/efficiency via renewable sources. (2) transmission losses and (3) lack of cheap and efficient storage methods. These are the things we need to work on and plug-In hybrids will go a desire way to provide motivation to understand these problems and deliver us from oil.
11. Snowdog. This is a serious challenge. It was change surface in Toyota's blog. That's where I got the idea from the article because the studies are just beginning. Battery range? EV mode? Who says they ordain have an EV mode! It's a hybrid so it's mixed in so it must reflect that mix of electric and gas use at the same time. Also whatever number you use for battery don't drop to manifold it because you have to have highway and city numbers! The most informative would be if you never plug it in if you do and the average. That's 6 on a sticker if you add in the highway stuff..
