Plug-In Hybrids Aren't Coming, They're Here

Wired is running a story about the small but vocal, and growing, number of people who aren't waiting for automakers to deliver plug-in hybrids. They're shelling out big money to have already thrifty cars converted into full-on plug-in hybrids capable of triple-digit fuel economy. "The conversions aren't cheap, and top-of-the-line kits with lithium-ion batteries can set you back as much as $35,000. Even a kit with lead-acid batteries — the type under the hood of the car you drive now — starts at five grand. That explains why most converted plug-ins are in the motor pools of places like Southern California Edison... No more than 150 or so belong to people like [extreme skiing champion Alison] Gannett, who had her $30,000 Ford Escape converted in December. Yes, that's right. The conversion cost more than the truck."

      Or, someone who thinks it's pointless to start with a friggin truck if you're trying to be fuel efficient..?

      First - I kinda object to calling a Ford Escape a 'Truck'. A Truck has a bed, normally uncovered. The Escape is a SUV.

      Going on - it depends on what you need. If you need a truck, and there are people who do, does it make sense to try to punish you by restricting you to the old wasteful power systems? Or do you go ahead and come out with a hybrid truck, even a PHEV?

      Consider the taxis in NYC. NYC, in all it's glory, has decided that the only vehicle that meets the needs to be a taxi is a stretched crown vic that's 6" longer than even the regular vic. Recently they decided to issue some green medallians - and the hybrid that came close enough to their ideas of acceptable storage area and leg room was the Escape. Which gets something like 5 times the mileage of the crown vic. Taxi drivers love them, and there's still room in the vehicle for 3-4 people and all their luggage for a trip to/from the airport.

Electric motors have good torque too so they'd be good for hauling, as long as they have enough charge..

      Well, there's a lot to consider when you look at making a hybrid F-150(or equivalent). Still, there are a lot of potential benefits. Off the top of my head:
      1. Weight - for towing capacity, you actually don't want the thing too light. Still, the battery pack, especially for a PHEV, is going to add a lot of weight. Best spot to put it would probably be right in front of the rear axle.
      2. Space - Should have relatively few problems finding some space under the bed for it. Looking at my truck, I should be able to have boxes 6" deep and 24" wide on either side of the axle and still have quite a bit of room.
      3. Structure - Trucks have to be designed to take more abuse and loading than cars. For example, an 08 F-150 is expected to be able to tow 3,700 pounds, and carry 1,976 pounds in the bed. Using advanced techniques, you could probably shave off almost as much weight as the batteries would add, but that'd get expensive, and maybe fragile. Elegent failure modes are a must.
      4. Towing capacity- good and bad here. I've been learning a lot about towing recently, and the engine plays a large part here, and most importantly, not just for propulsion. When going downhill engine braking is important to keep from overheating the brakes. So the bad part - you're unlikely to be able to undersize the engine much in order to be able to tow that 3.7k pounds down the highway at 75, or up a 15 degree slope for a hundred miles, or down a 20 degree slope for 20 because a smaller engine can't brake as well. The good part - electric motors provide great torque at low velocities, easing starting from a stop, and with regenerative braking can save quite a load on the engine and/or brakes. Hmm... Might want to go the train route and put resisters on the roof to bleed off excess energy in case of a long hill. Maybe a tow mode sensor - traveling uphill, let the batteries drain. Travelling downhill, emphasis the regenerative braking.
      5. Economy. Trucks, due to their relatively oversized engines, get horrible gas mileage as standard. Going from 15 mpg to 25 mpg isn't out of sight, and will pay back quickly enough to be an easy sell to somebody with the money to buy and operate a truck.

If you want an excellent way to BS your mileage figures, you've got one right there. In my personal opinion, the only commonly used way to BS mpg figures that's even more dishonest than that is what some PHEVs do where they assume you'll use electricity for X percent of your miles, then ignore the electricity in the mpg calculations.
      2) They threw out even the most basic creature comforts like AC to get it as light as they did.
      3) Even *the frame* is made out of magnesium. Magnesium makes aluminum look like steel in terms of strength. Again, if you want to throw safety out the door, you can lighten a car to almost nothing and then cheer its ridiculous numbers. They do use carbon fibre, which has a great strength to weight ratio, but only a tiny amount of it, and is no substitute for having a proper frame underneath.

(For extra credit you can refer to antepenultimate, which means third-best.) I don't really think this is a grammar Nazi issue: it's more like talking about C when you mean to be talking about C++.

  20. And the lights, and the steering, and the aircon? by Kupfernigk · · Score: 3, Insightful
    Enough with the sarcasm already. Perhaps I'm technical because I have actually worked in vehicle R&D and know something about it?

    The fact that the CPU and the electronic peripherals will run down to 8V - which is necessary because of battery volt drop on cranking - is irrelevant. It is the lights and the actuators that are affected by reduced battery voltage. In fact, looking at the linked article, the guy admits that he does not run without an alternator after dark, which at least shows some element of self preservation.

    The idea behind plug-in hybrids is to make the electric motor the big engine and have a small gasoline motor who's only job is to charge the batteries when they get low.

    I've always wondered if having a regular gasoline engine to turn the generator is as efficient as a small turbine. Supposedly turbines are most efficient at constant speed/load, which the generator would be. Anybody have any hard numbers?

  22. Throw out the transmission. by Ihlosi · · Score: 2, Informative

    I read about an interesting hybrid concept a while ago - it basically eliminated the transmission from the car to save weight. The car would use the (small) gasoline engine to charge the battery and drive the electric motors as long as the car was going below the normal highway crusising speed, and engage a clutch to directly power the wheels with the gasoline engine once the crusing speed was reached. Advantages were the lack of a transmission (= weight and space that can be used for batteries instead) while still being able to power the wheels directly (making use of the efficiency of the gasoline engine when cruising).

      So, for normal stop-and-go traffic your ICE would basically be driving a generator the entire time. Sounds like a great way to reduce overall efficiency in normal, day-to-day driving scenarios.

      No, because in this scenario the ICE would only run to charge the batteries, and when it runs, it can run at its optimal working point.

  23. "off-peak" electricity production and transmission by shmlco · · Score: 2, Informative

    "A new study for the Department of Energy finds that "off-peak" electricity production and transmission capacity could fuel 70% percent of the U.S. light-duty vehicle (LDV) fleet, if they were plug-in hybrid electrics. (Note: an earlier version of this release referenced 84% capacity based on LDV fleet classification that excluded vans)."

    Looks like they went and changed one of the numbers on me. Oh well, 70% is still a respectable number.

    Add this: Converting your car to electricity eliminates a point-source of pollution. If you moved all of your transportation's emissions back to the power plant, we can deal with them better. (The pollution controls at the power plant are better than the ones on your car: they don't get bumped around, have more consistent operating conditions, etc.)

    Now if EVERYONE did this, we might get enough concentration that we could actually DO something with it. Problem is, our pollution's too diffuse to be exploited.

    Consider: district heating. "Neighborhood" generators can be a way to exploit the waste heat.

    Carbon sequestration: this still remains a sham-dance IMHO, but maybe we can pull it off when we've got enough stack-emissions in one place. Sure not putting an Einstein-Szilard fridge on your car's tailpipe to catch the CO2.

    So mod the parent up. It's as simple as this: convert the energy as few times as possible (how did that gas get into your tank?) and concentrate the pollution where you can hopefully get some value from it.

    Call me back when GM is actually producing them and selling them. Your hypothetical price for the Volt strikes me as being extremely low. Wikipedia says that the price is currently unknown and could be as high as $48,000 depending on a lot of factors which simply can't be determined until it starts being sold.

    Meanwhile I bought a Malibu used for $13,000 several years ago. It gets 35MPG on the highway, drives great, and has plenty of power. I also routinely make trips longer than 40 miles with it, imagine that. Seems like the right choice to me!

    Whenever you can't disprove something, make it encompass so many other items that it becomes incomprehensible without the services of a complete auditing team. Then extend it just a little to include data that you probably can never collect.

    We saw this with TCO studies that tried their hardest to show that Linux might not be cheaper than $800 per seat licenses of Windows. While many people saved money by switching (Sherwin Williams, Fender Gituars, etc.) most complained about the intangible losses that they couldn't prove which justified their non-action.

    We saw this with global warming. Most argued about specific point data that didn't follow the average (hint there's outliers in every interesting data set), argued that costs would never be calculable for the issue, and built a model of "let's wait and see" which justified their non-action.

    We're seeing this with electric (or semi-electric) vehicles. It should be enough to note that we will mostly be charging the cars during non-peak hours, when the grid's capacity is most likely to meet the demand. It should be enough to note that for the same amount of used energy, the electric company can provide it to us cheaper than the gasoline distribution chain. It should be enough to note that at least a dozen ways in which the vehicles are cheaper to maintain offset the initial costs of not having a mass market's cost structure.

    Instead, we have to calculate the exact dollar of every line man, telephone pole, coal miner's life insurance plan, etc, ad infinitum. I'll give you a hint: The power company already does this, and it's called your electric bill, which is still cheaper than your gasoline bill.

    Just because you don't have it itemized doesn't mean it's more expensive.

    For those that enjoy these sort of games, have you even considered the operational costs of the thousands of oil tankers? How about the costs of all those oil platforms? How about the costs of the fire policies on those platforms? etc... ad infinitum.

    Prove to me that my electric bill will be higher than my gas bill, and I'll go with the parent poster's observation. It is the only sensible metric. And oddly enough, it should include all of those "other" costs, because if it didn't the company would be out-of-business before you know it.
