Inexpensive Electric Cars May Arrive Sooner Than You Think 330

catchblue22 writes According to an article in MIT Technology Review, a new peer reviewed study suggests that battery-powered vehicles are close to being cost-effective for most people: "Electric cars may seem like a niche product that only wealthy people can afford, but a new analysis suggests that they may be close to competing with or even beating gas cars on cost. ... The authors of the new study concluded that the battery packs used by market-leading EV manufacturers like Tesla and Nissan cost as little as $300 per kilowatt-hour of energy in 2014. That's lower than the most optimistic published projections for 2015, and even below the average published projection for 2020. The authors found that batteries appear on track to reach $230 per kilowatt-hour by 2018. The authors found that batteries appear on track to reach $230 per kilowatt-hour by 2018. If that's true, it would push EVs across a meaningful threshold."

        I think you need to do a little research about the way electric cars operate in stop & go traffic. There is no idling like with an ICE. It just shuts off when you stop.

    Although cheaper helps, there are still numerous disadvantages to electrics (range anxiety, ability to recharge cross-country, cold weather conditions, etc.) that aren't up to parity with ICs.

    Even if Teslas were $10,000, they'd still be unsuitable for a large portion of drivers. Until infrastructure problems get addressed, or manufacturers get a clue and start incorporating range extenders (I so long for a series hybrid), electrics will be on the fringes of the market.

    Although when these guys:

    http://wrightspeed.com/ [wrightspeed.com]

    start to retrofit autos, that could mark the critical mass to finally push electrics mainstream.

    • Most electrics are bought as a 2nd car, since a vast majority of people don't driver further then 50 miles a day. So the range anxiety may be a moot thing, since lots of people use their gas car (or choose to fly) rather then worry about driving their electric car across the country..

      I don't disagree that gas cars have certain disadvantages but Teslas would meet probably (and I am just throwing this out there) 95% of driving needs. They have a range of 200-270 miles per charge which doesn't cover the cross country trip but is certainly good enough for the daily commute and even a ~4 hour trip to out of state friends house. If the Tesla was $10,000 I bet that 50% of cars on the road would be a Tesla.

      I think that Toyota hydrogen fuel cell is far more practical and cleaner (because electric batteries are charged with coal fire plant electricity made 500+ miles away from where it is used).

      Toyota is offering fuel cell engine patent use for free until 2020.

      Range is good. Output from engine is water vapor. Clean as a whistle. Energy is created and used together rather than created, shipped over hundreds of miles of wires then used to charge.

        there are no reserves of pure hydrogen. It has to be 'cracked' from molecules, typically hydrocarbons (nat. gas and oil!) or water, and getting it from water takes a lot of electricity...hello Mr. Coal! And once you create it, it has to be shipped. So it's no cleaner than running batteries, and has some serious downside.

        • No, they don't use electrolysis. They make it from natural gas, giving your "clean" energy source the same carbon footprint as an electric car. Also hydrogen is expensive to store and transport.
        • They use electricity by way of electrolysis. This is a hideously inefficient process.
          That is wrong. Electrolysis might not be that efficient, but it is not particular inefficient either. It is certainly far far more efficient than burning gasoline in an ICE.

        I think that Toyota hydrogen fuel cell is far more practical and cleaner (because electric batteries are charged with coal fire plant electricity made 500+ miles away from where it is used).

        Really? Hydrogen? Ok. First off, hydrogen is an energy carrier, not a source. Most hydrogen for transportation these days comes as a bi-product of fossil fuels. So that's not really so clean.

        So what if we make the hydrogen from H2O using electrolysis...that means we split 2 H2O molecules into 1 O2 and 2 H2 molecules. There is going always going to be some heat generated in this process, which is by definition waste.

        The real and fundamental flaw in this process comes next. In order to transport and use the hydrogen, you have to compress it. This takes energy. Extra energy. And when you compress a gas, it gets warmer. This is a fundamental law of physics. So we have compressed hot gas. What happens to that heat energy? It will certainly not be used to power the car. It will likely be wasted.

        Next, you have to transport the compressed hydrogen gas. This also takes energy. Energy that will be lost.

        Another large problem with hydrogen gas is that the molecules are small. Why is that a problem? Because it will be difficult to contain the gas. It will tend to escape. The gas will be lost in compression, in transport, and in storage. It is likely that if you fuel your hydrogen car up and park it, you will lose most of your fuel to the air in several days.

        Finally, we have to change the energy in the hydrogen back into electrical energy to power the electric motors. The efficiency of fuel cells is an engineering problem, but I suspect there is some intractable physics in there that will cap the efficiency. Let's assume a best case scenario of perhaps 50% efficiency for the cells. That is still a lot of waste. However if you factor in the losses from electrolysis, compression, storage as well, you will have an overall efficiency less than 50%. Probably quite a bit less. So let's say for the sake of argument that the entire process is 30% efficient, which I suspect is generous.

        It is well known that the electricity transmission system is highly efficient. Some easy research should tell you that the transmission system is more than 90% efficient. When we charge a battery, there are come losses. But they aren't that high. Let's assume the charging system is 80% efficient. Overall then, that process would be 72% efficient (I think it is higher than that actually).

        So, if you have 100J of energy that you wish to use to drive the electric motors in a car, you can use hydrogen, and get less than 30J to the motors, or you can use the electrical grid, and get 70J to the motors. Honestly, why would you use hydrogen? Especially since the fuel cells would be complicated, expensive, and of unknown reliability. Hydrogen as a fuel is flawed at the level of fundamental physics. These problems cannot be engineered away.

      • And the hydrogen used in a hydrogen fuel cell is made how exactly?

        You do know that only a moderate, slowly decreasing percentage of energy production in the western world is done with coal?

        You also do know that the equivalent of a gallon of gasoline in hydrogen costs more or less the same price as gasoline? At least in Germany, so I assume in the USA the equivalent costs about twice as much.

        So right now hydrogen is a nice thing, but expensive.

      Tesla has been doing their share for charging, at least for their own autos, The speed of deployment of the Supercharger network is impressive given the relatively small size of the company. I believe that the current availability in America is almost 200 locations with usually 4 - 8 charging bays each and plans to double that number by Fall 2016.

      They've also installed hundreds of 80A chargers capable of 10-20 kW at restaurants, malls & hotels.

      Series hybrids are a terrible idea. See the BMW i3. It has worse mileage than most comparable cars. Its speed on petrol is limited, and the fuel tank is too small to be useful.

      An electric drivetrain costs in the region of 30% of the energy that the engine puts in. Stuff an 8-speed modern automatic in there instead, and you keep the engine at almost the ideal RPM at all times. That drive train will have close to zero loss. Or put an extra electric motor in (two in total) and you get a variable ratio gearbox

    That they'll replace my (2012) Volt battery free for the 8 year warranty if it drops to less than 80% new capacity, and current out of warranty replacements are priced at ~$2500 + labor (which is easy, but of course any dealer will overcharge). Just sayin. They probably lose money on that. Why should I care? Range anxiety? Get a Volt, there is none.

And my particular Volt has never been charged from the grid since it left the factory (off grid solar, baby). At that, it probably costs less than replacing any major drivetrain component in any other car. And I don't wear out the engine (usually I get all-electric), brakes, you name it. It's looking like I won't be having to buy any new cars for a long time now. Those other costs (oil changes...) add up too. No one ever seems to work all this out fairly, but I can say my wallet is getting a lot fatter from owning one.
