Battery for electric car.
At the moment I would not buy an electric car because of their price,
poor range, short battery life (8 years) and unlikely to be warm inside during the winter. But maybe I could have an electric car with a Lithium ion phosphate battery like this: https://www.sciencedaily.com/release...0118113126.htm Charging at home might take longer than 10 minutes! -- Michael Chare |

Perhaps some people need to do the ****ing sums. Bad day? If you're going to an "electric station" to get your car "refilled" with volts, you're not gonna put up with it taking 10 minutes. 5 at the outside. A 40kWH charge in 5 mins is 12 x 40kWH per hour, or 480kW. And if my local Morrison's station is anything to go by, there could be 12 at it at once. So, allowing for time to pay, say 400kW continuous at peak time, or 4.8, say 5MW. Just for one "electric station". I don't think this would be for your local Morrisons, because many of the people doing shopping runs would be slow-charging at home or on-street. This would be targeted at long distance drivers who need a quick fill up - motorway services, truck drivers, etc. In particular for trucking you can get away with a smaller battery (ie more payload) if you can fill up regularly and rapidly. If you're using it only on larger sites it simplifies things because you can spread the costs by building on a bigger scale. Oh, and 480kW. That's your choice of 480V at 1000 amps or 1kV at 480 amps. Either way, not a cable you want to be handling even assuming you can lift it. There are already robotic charging stations, and I assume that might be needed here. For example a charging connector on the bottom of the car where, once the negotiation and optical alignment is complete, an arm comes out of a panel in the ground. You can also do robotic to conventional 'fuel flap' charging sockets, but the mechanism is more complex. A car might provide both - fuel flap for the humans, port underneath for the robots. And it gets worse: Assume 99% efiiciency in the process. That means you're looking at getting rid of 5kW of heat generated by the charging process. That's 60kW for the whole station at peak times. Good luck with that. Depending on where the heat is generated (conversion electronics rather than cabling?) you could maybe run a small heat/steam engine? Either way, 60kW isn't actually that much - it's roughly the output of a petrol car engine, which is easily cooled (even when not moving). However a bigger challenge is how to supply that power from the grid, which won't like such huge demand spikes. I presume it would need a local battery that is slow-charged (in MW) from the grid and then provides the current spikes when charging vehicles. It also might have its own solar/wind/etc generation to reduce grid demand and also transmission losses. Various things that aren't quite here yet, but I'm sure could be engineered if the demand was there. Theo |

Um, you know what Lithium iron phosphate is ? That's the battery in the fairy lights in the garden. Scaled up in size. The reason those batteries are in Model 3 cars manufactured in China, it's part of a Chinese mandate. There isn't an infinite supply of Cobalt, so some of the battery demand will be satisfied with Lithium iron phosphate. The Model 3 cars with that battery type in place, are for domestic consumption in China at the moment. Presumably, this was the pill Musk had to swallow when getting permission to build a plant there. Cubic volume wise, Lithium iron phosphate has half the range of Lithium Cobalt. Are you celebrating yet ? Yes, universities release press releases all the time, but many of the chemistry advances sink without a bubble appearing on the surface. Lithium iron phosphate can still catch fire, but it's more abuse-tolerant than the cobalt ones. I don't know about charge cycles. Remember, that in a car application, any sort of fast charging algorithm, pushes the batteries to the wall. Anecdotal evidence from owners is, the more times you use the "max rate" fast charger, the more the car smart charging algorithm prevents you from using it the next time. To meet warranty life, the smart charger "backs off and takes longer", so that the pack will meet warranty life and not need free replacement by the manufacturer. And I don't really know how many cycles you get from a fairy lamp when pushed. Fairy lamps get microamps from their little solar cell, and they never stop charging (there's no charge controller needed because they will put up with charging abuse such as trying to fill them when they're full). But if you're a determined twit, Lithium iron phosphate will eventually catch fire, as it has a thermal runaway condition just like Lithium Cobalt does. All the Lithiums do, because... Lithium. The Lithium iron phosphate needs just as careful attention to charge termination as Lithium Cobalt. While the fairy lamp can overcharge with glee (at microamps of current), a car sized battery would not put up with pushing 300kW into it when it's full full full. Now it wants to catch fire. Paul |

Bill There is a way to charge BEV cars without "hose pipes". https://www.pluglesspower.com/learn-about-plugless/ The only disadvantage of the method, is it wastes about 10% of the energy consumed or so. There are losses. But, it means you could install those pads in the street and charge the cars with them. And with no cables or pedestals next to the parking spot, there are fewer materials to vandalise. (Damaged charging infrastructure and out-of-commission chargers are more common than they should be.) And it doesn't solve the problem of power distribution. There still has to be a jolly great transformer somewhere to power it. And as infrastructure costs go, those aren't cheap. It can take as long as two years, to wind and assemble a custom transformer. But with a method like that, with overnight parking you might get away with a 7KW feed per pad. There's no particular need for 345KW in those parking spots. If you can afford a Porsche Taycan, I don't see a reason you can't afford a custom charging station for your drive. You could run six of those off one windmill. And be finished 22.5 minutes later. And this example, is a way for Porsche to demo fast charging, without worrying about electric company infrastructure at P.R. events. https://newsroom.porsche.com/en/2020...ces-22285.html Paul |

You've obviously had a few :-) TBH on a motorway a self driving car end to end with others is no bad idea, but KV on the road surface is a very *bad* idea. The bikers wouldn't be too keen. I guess you could engineer something switched and/or enclosed and at a lower voltage (not kelvin-volts as you suggest anyway), but it would be difficult. The main issue would be operating and manning the very large hand controllers. -- Cheers Clive |

If you have to park on the street you could visit a local charging point and wait jiust a bit longer than it takes to fill a car with petrol or diesel. I really can't see the problem of providing on street chargers for every single parking bay on the street. After all we now have phones in our houses, where once you used a phone box. About three orders of magnitude in the size of the copper cables required. -- Roland Perry |

Do you remember how much it cost to have a phone installed in the days when most didn't have them? That was because the GPO had a monopoly. Mrs Thatcher sorted that out for us. Bill |

Mrs Thatcher sorted that out for us. It still is pretty much a monopoly. Except alternative suppliers can pick and choose the areas they cable. The biggest difference was that we were allowed to connect devices through a single master socket. I think that was sorted by various interests wanting to sell telephone equipment who lobbied the government. |

I think that was sorted by various interests wanting to sell telephone equipment who lobbied the government. It was more the philosophical issue of breaking the monopoly because the GPO phone was only available as rental. As soon as you forced the GPO to allow you to buy one instead, you had to allow alternative suppliers. Oddly enough, when ADSL was rolled out initially, you were forced to rent the modem/router from BT, and it was only when the "wires only" product became available that you had a choice. -- Roland Perry |

But maybe I could have an electric car with a Lithium ion phosphate battery like this: https://www.sciencedaily.com/release...0118113126.htm Charging at home might take longer than 10 minutes! I do wonder what home supply you had in mind you'd need to charge 40 kilowatt hour batteries in 10 minutes? Is every house going to get it's 240kW supply? Were you thinking 3 phase 415V at 200A per phase or single phase at 240V at a mere 1,000A? No, I think the idea is that petrol stations get repurposed as charging points, making the process of refuelling much the same as it is at the moment. Ah, my mistake. I'm still wondering how this might be achieved. There are a few 2MW gensets on the market. Could cater for 8 charging points? Perhaps I need to buy futures in copper. The battery would make the whole idea of an electric car much more pratical. If you have off street parking at home you could charge the car slowly overnight. If you have to park on the street you could visit a local charging point and wait jiust a bit longer than it takes to fill a car with petrol or diesel. I rather like Tesla's idea, I think now abandoned, where you swap batteries. You could even choose a capacity for your next journey to keep rental costs down. There have been many proposed batteries that have come to nothing. Before Lithium chemistries were all the rage Sodium Sulphur was the in-thing. https://en.wikipedia.org/wiki/Sodium...sulfur_battery So, when I see a battery in some scaled production that's when I take notice. Choosing a battery capacity would, on its own, be fine. But whatever technology, the battery's mass will approximately double as the capacity doubles. Designing a car which drives well but can cope with its heaviest single component varying in mass by such very large margins is a challenge. Maybe, if the additional battery were treated like a trailer, it would be possible? (Imagine a trailer that has it own wheels and snuggles under the boot. So doesn't make the vehicle longer.) |

Has the advantage of better aerodynamic efficiency too, if you have a few. Take the driver out of the equation and things become easier. But makes self driving cars even harder to do. |
