back to article Where am I going tomorrow? My electric car charger wants to know

There’s a definite green tinge to Intel’s European Research and Innovation Conference (ERIC) this year, with a cash-saving electric car charger being touted alongside energy management ideas. It's not escaped El Reg that Intel is touting its green tech wizardry in Leixlip, Co. Kildare, in the Emerald Isle. The "context-aware …

    Downside

    The downside is that you start out with a less than charged battery, so you end up discharging the battery deeper than if you started out with a fully charged battery. And the deeper you discharge a battery, the shorter the battery's life.

    And what do you do if an unexpected trip comes up? I've had to go and pick my kids up from school when they were sick and take them home. But I wouldn't be able to drive back to work because the battery was too low because it only had enough of a charge put into it to go to work and back.

      That is going to be one complicated algorithm

      It will need to know what the weather is going to be to compensate for environmental factors like wind, rain and exteme cold. It will also need to compensate for battery degredation over time too. Sure you can make a best guess, but guessing isn't good enough when it needs to be 100% fool proof. People don't always know what they're doing from one moment to the next and getting them to plan far in advance would open up a whole can of worms. People may be leaving themselves vulnerable if the tablets that manage this system are not properly secured. Too much to go wrong. K.I.S.S.

    And when there's an unplanned trip?

    When little Jimmy manages to bang his head and need taking to A&E (which thanks to NHS cuts is now 15-20 miles away) you jump in the car and it announces that you're not supposed to be there?

    Part of the whole car owning thing is about the ability to make a trip on a whim, unplanned. This would appear to be trying to regiment everyone's life into their online calendar (who else can see it? no doubt the plod & the like want to know what you're planning)

    This whole battery-powered car thing is an evolutionary dead end, alternative fuel (hydrogen is promising) is the answer.

    1. Paul E

      hydrogen is fine except the fuel cells in the few cars on the road at the moment cost, I believe, about 250,000 pounds. Unless someone can make one with a lot cheaper components hydrogen will be hobbled both by the lack of infrastructure and the cost of the components.

      As to your question you check to see the range on your car and if not long enough you call an ambulance the way people without cars do.

        Hydrogen

        Hydrogen is a waste of time at the moment, really it is.

        It's an expensive process to make Hydrogen, currently it's made from converting Natural gas would you believe. Also it contains less stored energy that petrol.

        El Reg should investigate and write an article on it.

        1. Graham Dawson

          @AC

          It's true. The issue is energy density, something that fuel cell, hydrogen and battery advocates always either ignore or prefer not to talk about.

          Currently the most efficient form of energy storage for road vehicles is petrol simply because it packs the most energy into the smallest space without the need for expensive, dangerous active storage facilities. Hydrogen can leak from even the most perfect of seals because it's so small and requires extreme compression to achieve even remotely the same energy density as petrol, which then requires expensive and dangerous cryogenic storage. Hydrogen fuel cells are marginally better but still suffer the same basic storage and transport problems as hydrogen. Batteries? They're largely dead weight. Look at the average battery powered car and you'll see that they're essentially useless. People complain about a phone that lasts less than a week, how will they act if they have to "fill up" their car every day? I'd only have to fill my car every day if I was doing a daily commute all the way from lands end to john o'groats.

          The only solution I can see is artificial petroleum produced in some sort of high intensity centralised facility (ie not one that requires the use of vast tracts of arable land and food crops). Everything else seems to be a waste of time and effort with very little energy returned on energy invested, especially given the fundamental rebuilding of a large chunk of our infrastructure and economy that always seems to go along with them.

    Since when was life that predictable?

    Compare and contrast:

    Situation:

    You go to work for the day, come home and at some point in the evening a family member is taken ill and needs to go to hospital. This may not be life threatening, in which case the Ambulance service wont respond, they will expect you to do it yourself (not unreasonably, in the case of non-emergency admissions)

    Case 1:

    Conventional car.

    You: "Right, lets go, I'll make a quick stop at the petrol station on the way because I was going to go there in the morning before work"

    Result:

    After a short delay, you arrive at the hospital

    Case 2:

    Electric car charged to the minimum requirements for expected use

    You: "Dammit, the battery is flat and there won't be enough charge in the car for several hours"

    Result: Unnecessarily long delay in arriving at hospital and your loved one being treated.

    Now, I realise this is a very specific circumstance, but it usefully illustrates the wider point that life simply is not that predictable. In the case where cars can charge to at least 80% of their total capacity in 10 minutes, this would be useful. As it is currently more like 10 hours, sorry, I don't see it.

    I know there is an overhead (possibly quite a big one) in using hydrogen to power a fuel cell, and for this reason many see it as unsuitable, but as technology improves, that overhead will drop and you can still fuel your car in a matter of minutes, plus we handily avoid many problems of overloading the national grid at peak times, running cables across the pavement for those without driveways and so on.

      Hardly a week goes by...

      without a news item about new technologies being announced that promise to increase the capacity and speed of charging. At the moment a car like the Nissan Leaf can only do 100-120 miles but new technolgies promise to improve that to several times that figure and I would suggest that an electric car that could do 300 to 350 miles per charge is not too far off (the tesla can do it now but that does not count in the context of normal folk) and that that would not be a 'toy'.

        you can go three times as far now

        but the batteries will weigh 3 times as much (so you won't go three times as far as you have to cart that extra couple of tonnes of battery around with you) and take up 3 times the volume - so the car will be at least half as big (so it won't go three times as far because of the increased drag - and weight of the monocoque shell)

        and of course - with a mains fuse of only 50 amps in your house it will take three times as long to charge.

        And with out the subsidies that the Leaf etc all get (some 30% plus of price) it's going to cost three times as much.

        And do three times the environmental damage in making the battery and disposing of it after 5 years - at about the same cost as a new car

        100 miles ... erm, yes but no but

        Well yes, it can do 100 miles as long as you only drive at 35mph for a small 1 or 2 mile burst and restrict the other 99 miles to 20mph or less.

    Unlikely to be flat to start with though is it?

    Why is it that in these 'scenarios' those against electric cars the car just managed to make it home that even and is completely flat?

    Most journeys are about 20 miles and the range at the moment for electric cars is about 100 so most evenings the charging will take you from about 60 to 80 miles up to 100, if you need the car in an emergency you still have the 60 to 80 miles to use and as long as its plugged in every day its highly unlikely to get down to zero and if it does you press the 'big red button' as the story says to make sure its up to a usable range as soon as possible.

      WTF?

      Err..??

      You seem to have missed the point. If it starts day 1 with 100 miles of energy and you do 22 miles per day then it won't charge until day 4 evening and then only enough to do the 22 miles you planed on for day 5. If you need to do another 10 miles (take kiddie to A&E) then tough cheese.

    3. Dave 15 Silver badge

      Rot

      a) The range is NOT 80 miles in most electric cars unless you are prepared to drive along at the speed of a bicycle. In most scenarios of reasonable speed the range is down around 30 miles

      b) I don't know where this figure for 'most journeys' is - the SHORTEST commute I have ever driven was 15 miles each way. My current commute is 25 miles each way. My longest commute was near 50 miles each way.

      If I want to see my son its 260 miles each way.

      Electric cars are just the wrong technology. We need something that actually works - all the money and effort on a dead end technology is just not helping us with the basic problem, we need to ditch the petrol engine.

      My current daily commute is along a dual carriageway, I do it at 50mph to save fuel at this speed I have some serious problems with the lorries that are (illegally) trying to do rather more than this and get upset with me. I can't imagine taking one of the lightweight electric cars along at the 25-30mph it would need to do in order to complete the journey. The fact I could then charge it for 8 hours at work is a bonus, but by the time I get home of an evening I wouldn't be able to get to rugby training or the gym...

          Ethanol burns cleanly, it is easy to store and its only weakness is that it is a bit harder to get going when it is -20C or colder outside. (so my car comes with a block heater pre-installed)

          Plus the exhaust smells quite nicely in cold mornings.

      2. Dave 15 Silver badge

        minor problem

        The main objection to petrol is the CO2 produced... ethanol will produce CO2 as well.

        Now, if we were to run methane then it could be collected from the sewers, true burning this also produces CO2, but as CO2 is mess damaging than methane in terms of greenhouse gas then that is better. The methane is a natural biproduct of so many humans. In fact, thinking of the beer problems below my methane production is higher when I've had a load of beer and a kebab, so perhaps the government will see the advantage of lowering beer tax in order to encourage more methane production :)

    Not going to work

    I don't put shopping trips in my diary, and they aren't that predictable. It is quicker to walk than drive to my local supermarket, so routine shopping does not involve the car. I take the car if the weather is really bad, I am going to take something heavy home, or I go somewhere other than the local supermarket; and I don't put any of those things in the diary.

    Also, I might wake up one weekend day, look out and see that the weather is very nice, and decide to go on a day trip somewhere.

    Besides, just in case anyone forgot, electric cars were around before diesel and later petrol cars were invented. They were very popular in the 1920s and 1930s in the days when diesel engines took about 30 minutes to get going with a starting handle, and were very noisy and smelly. In other words, they are old obsolete technology which is unlikely to come back any time soon.

    What about those days where someone has an accident and Mr Plod and his traffic womble friend close a road or 5 for the better part of a day while they make pretty lines and take photos? how will this cope with the detour that could involve.

    Alternatively.

    Fully charge car. Use car. Look at charge gauge on returning home. Decide whether or not it needs topping up for the next day. You know, exactly the process you use now when you look at the fuel guage and go: "Aha. Must go to the petrol station tomorrow....".

    The advantage here is that you know *everything* that you might be doing the following day and how much "spare" you'd like, rather than just the bits you've put in your diary and some generic algorithm's guesstimate.

      If everybody does that, it's not off-peak anymore.

      The really, really, really *MASSIVE* problem with electric cars is that in a world where a lot of people have one, they all charge it overnight.

      That's currently the time when the Grid can use the idle speed of coal and nuke plants to pump water up hills for when Corrie ends.

      If everybody wants to re-juice their cars during that time, the economics of pumped storage stops working.

      To make life more interesting, that same world where everybody has an electric car is the one where there are no coal plants, just lots of windfarms*.

      In a high wind-penatration situation, you are *forced* to use radical demand management because the wind doth blow when the wind bloody well wants to, and not at our convenience.

      "Demand management" is another term for "Blackouts". This project looks very much like an experiment to see if people will accept blackouts if they only affect their cars.

      The best part of it is that if you hand someone a free car in addition to the petrol/diesel one they already have, they probably won't mind if they can't use it for 'unscheduled' trips. In fact, they probably won't mind being told "you can't use it today".

      Now take away the petrol/diesel car, and ask them to pay for the electric one. They will refuse to buy that vehicle if you give them either of the above restrictions.

    Overly complicated

    The basic idea is good, it has just been made way way way over complicated.

    What you need to tell it are two basic things:

    1. Minimum acceptable charge level/range (ie how much charge you need to get to and from the hospitable in an emergency).

    2. When you want it fully charged by - eg 6am.

    The charger is clever enough that when you plug it in it works out when to do the charging.

    If the battery is below 1 it starts charging immediately.

    If it is over 1 then works out how long it takes to charge to full and uses the most optimal approach to perform the charge - ie if the car is at 95% it may turn the charger on at 3am to do the rest of the charging when it is cheapest.

    Linking into online calendars and everything is just an optimization and complication too far.

  20. Paul E

    The bit about the diary..

    sounds a bit like techy feature creep to me. The main interesting point is that the elec company can control your recharge from their end to even the load. If you car takes 10 hours to charge from flat and you arrive home with no charge then it should allow you to start charging immediately but for the vast majority of people where they arrive home with a significant amount left then there are obvious advantages to the power companies controlling when that charging takes place.

    Surprised that no one has mentioned the possibility of the power going the other way when peak power is required. Power companies would charge you less when you did charge and they would gain extra capacity at peak periods. Possibly not feasible with today's battery tech but say you had batteries that could go for 300 miles then letting the elec companies drain it from say 200 miles range down to 100 during peak demand periods and then charge it back towards 300 when off peak could well be a sensible way of coping with varying power needs.

    Battery swapping stations are the only answer.

    The swapping station company can then charge them up whenever power is cheap and we can just carry on with life as normal.

Trying to a) Get all the car manufacturers to agree a standard for the battery packs and b) building an infrastructure far more expensive that fast chargers for the rare occurrences when a driver is unable to get to their destination on a single home charge just will not work in my books.

      What is happening is that the pace of battery development is increasing with a number of technologies that promise to double or triple the range for no increase in weight. Once we get to the point where a normal (i.e. not a tessla) electric car can do 300 miles on a full charge then such battery replacement sites will become even less used.

    I don't see the problem. Standardise the battery form factor and have a robotic system to swap out a discharged one and stick in a charged one. The machine should measure any residual charge and only bill you for the difference plus a bit for the "fuel station" and for the wear & tear on the battery.

    When batteries are beyond further charging they go back for recycling and the cost has been covered by the "and a bit".

    Standardise on something that you would use 1 for a motorbike, 2 to 4 for a car, maybe 6 for a light van and a dozen or 2 for a lorry.

        Peter, I disagree

        "go and check exactly how heavy those battery packs are."

        Which is why I suggest using multiple small packs per vehicle, each one a size suitable for a electric motor bike so not exceedingly heavy.

        Health and safety is no more of an issue (probably less) than when dealing with exceedingly inflammable and volatile liquids such as petrol.

        We’ve been handling petrol for ages and are blasé about it but if it were introduced now do you really think the current infrastructure would pass muster? Next look at the problems that would apply if we used liquid Hydrogen as a fuel and you’ll see that electricity is the safest and easiest to handle of the current possible fuels.

        As for the power grid well however you carry the power in the car and no matter where the chargers are you are going to need beefed up infrastructure and it would be far cheaper to run high current 3 phase to a few garages than to run a high current supply to almost every dwelling.

      not simple

      The batteries actually have a very limited lifecycle, so the costs are not going to be trivial

      Having a store of batteries at a motorway services capable of replacing the 'flat' ones bought in during a recharge period (about 8 hours) is going to require a collosal investment. Looking at any reasonably busy petrol station you would need around 12 machines each capable of changing a battery pack every 5 minutes for 8 hours - so needing a store of around 1200 of these battery packs.

      Then physically not only do the batteries need to be the same but the location of them and means of accessing them need to be similar enough for a machine to cope. Thats not going to be all simple - even if you separate bikes, cars and lorries.

      Basically its just not the right technology.

    Then we have the cold snap ...

    That batteries are affected by cold weather is bad enough, but how will a low charged car survive being stuck in freezing conditions for 3 hours on the Sidcup bypass, like my brother was last year?

    Maybe once they have perfected the technology they can install it in lifts so they know which floor you want to get off at before you get in....

    Battery technology

    This all actually stems from battery technology and the ideal way to make your batteries (the most expensive parts of an electric car) last the longest. If you're using common Li-ion batteries in the car then you ideally want to charge to 75% capacity and not discharge below 25% capacity for the longest life span of the batteries. Run from 100% down to 0% on a regular basis and your batteries won't last a year. It's a similar issue with NiMH batteries. Use standard Lead/Acid batteries and you have weight issues, package issues and charge time issues.

    Battery technology is not progressing quickly enough to cope with Moore's law and it's not progressing quickly enough to cope with the Green agenda either.

    so ; most people seem to have worked out how seriously flawed (current technology) battery cars are. And how far off a viable battery is.

    They also seem to be aware of the time required to charge the battery.

    What no one has looked at is the fondle slab interface ....

    SAP - are you serious ? Who; apart from SAP programmers and Finance Directors have ever had a good experience with SAP ?

    The average punter is NOT going to accept Some Awful Program as the front end to looking after their car; it will take them longer to update the diary than it will take the car to charge for a 1000 mile journey.

    And then it will probably not cope with decimal points and confuse the luser even more by insisting the electricity supply tells it the unit costs in 0,001£ increments

    The toxic mix of Such A Problematic interface. and wrong technology (batteries) is about as certain a fail as electric cars being good for the environment (they are probably WORSE than ICE in terms of environmental wear and tear)

    WTF?

    Taxi?

    Re the various comments about emergencies and otherwise unpredictable needs for a car: There's a tried and tested fallback option available, used by many who don't have any car: It's a technology called "Taxi". You spend 20p on a phone call and 20 pounds on the ride (which would have cost you 2 pounds in petrol in an old-fashioned car). If the emergency happens every day, keep your petrol car. If it's once a week, charge your E-car fully all the time at a higher price. If it's once a month, the taxi is cheaper. It's a simple optimisation problem, and you may need to adjust your response to the pricing structure and your circumstances.

    1. Dave 15 Silver badge

      er, please...

      20p on a phone call to find no taxi available, 20p on another, then half an hour finding a pone book, 20p on a third.... after 45 mins or so finally find a taxi company, wait 30 minutes for them to drag themselves out of bed or wherever, another 20 minutes for them to drive out to yours, finally hear the honk of the horn then you can start your journey....

      load of old b****x

      There is an interesting other thing that could work with leccy cars - and thats the train - take the channel tunnel train, run it all over the country, replace the lines beeching scrapped, put back the stations, allow people to drive onto the train - maybe even to charge up on the train - and then the journeys we actually need to make are shorter and the mileage problem goes away.

      Actually - save us all a lot of hassle and do it anyway, then polution from the old fashioned petrol engines we use now will be so much reduced the whole panic will go away.

    What will we do with all the unused petrol?

    If I mis-remember my history, wasn't the petrol engine developed to use the "waste product" created while refining for diesel? So, when we reach this mythical electo-utopia, what happens to all the unused petrol? Do we burn it off from the top of the cracking towers? Hmmmm, now that would probably cause Global Warming. Then of course we'll come up with a "solution" - use it in personal automotive engines. And so the spinny-wheel spins again.

    But personally I think dragging big chunks of lead around is kind of spinny, like a sh*t house fly.

      Unused Petrol

      If the refineries have any surplus fuel left over then why can't they use it to generate electricity to feed into the grid? I'm sure that someone will think of a use for all that surplus electricity.

      1. Dave 15 Silver badge

        probably the same reason...

        that we don't collect the flare pipe gas and use it, or the methane from the sewers / rubbish tips - because those with the money to invest in doing such things would rather buy a new car

    So basically this increases the downside of electric cars....

    That downside being the limited range and the difficulty and length of time that a range-extending recharge takes.

    Sorry, but I think it makes no sense to take a car with limited range and limit the range even further. Many times I find that I have an unexpected errand or a social engagemnet comes up at the last minute--and that requires that I drive farther to get to those. I for one like having the ability to get to those without having to take a cab.

    what's in a title

    won't the economics of battery powered cars fail once everyone has one ? The cost of electricity will go up as it will become a scarcer resource, and the cost of fuel will also go up as it will be required to generate more electricity for the cars. Doesn't this mean that transport costs will go up no matter what ? Doesn't that also mean that the cost of everything will also go up ?

    I dunno I have probably missed something,

    WTF?

    Just buffer the power and be done with it

    Grid WILL have problem one way or another. They have the only means to regulate it - offer reduced price off peak - like at night. And that is going to be a problem once all the guys start charging at night.

    So what is solution? Simply put additional battery packs at home (and at work, and definitely - in "gas" station) and charge them when you will and at whatever pace you choose. And while you are at that - put that silly diary tablet computer away from silly humans and closer to smart batteries. This way it can "negotiate" the best deals on electricity with electric company or take advantage of silly wind mils when the wind actually blows...

    Sort of electricity stock market.

    In the end if YOU need to be prepared for urgent trips then you say to your system "charge ASAP" - it will draw power in peak time and it will be expensive, BUT this would not upset the grid balance as this very act would (generally) cause peak rates to increase and off-peak to decrease for other customers so they may shift off-peak and restore the "perfect" load balance.

    How would you manage this "electricity stock market" and enforce dynamic price for electricity to the customers is entirely another matter, but it definitely much more worth investing research dollar than silly idea of everybody syncing their bathroom time with world plus dog...

    Of course it would still work as it is with just two electricity tariffs. Dynamic prices are just a further convenience. You (power company) can (and probably would be forced) to calculate them yearly, but making it every month, day or minute would lead to power company dream - ideal load 24x7 and best price for electric company and each and every customer.

    Perhaps these people should get a life

    I certainly have a life. I can also inform these people that I can't tell you tomorrow what journeys I will make, whether the weather will cause me to have headlamps, foglamps, wipers and heater on or the windows open.

    Electric cars are a con and not the right thing at all. As a way of storing energy it is not the dense enough. It is also environmentally hostile with low lifetimes, vast quantities of heavy metals causing damage to the environment, the mining of the materials etc. also adding to problems.

    If they were the solution the charging would need to be very quick - like refueling is today in a petrol car. This suggests maybe some form of capacitor might be a better answer.

    Personally steam is the way forward - its a compact store of energy, easliy replenished, can be fireless, provided from petrol stations converted to supply steam in easy measurable and quick ways, created using any green fuel source and the use of it in transport is well understood. You don't need a thundering great steam roller or traction engine, steam lorries and cars existed (and many still do the London-Brighton rally). The materials can be normal steel and aluminium and not a dangerous and damaging new heavy metal. The steam can be stored in a pressure vessel which doesn't need to be a boiler (fireless locos used to operate in flour, gunpowder and munitions factories).
