It is reported that an electric-powered bus exceeded 1K km/miles on a single charge.
Details please. |

Why does an electric bus need a 1000km range? The bus may travel maybe 200km during the working day then be back at the depot for charging overnight. Wouldn't it be cheaper to build & run with a battery of half that capacity?
In fact apart from trucks in road trains in the Outback what vehicle electric or otherwise needs a 1000km range? -------------------- British Parking Association Ltd Code of Practice(Appendix C contains Schedule 4 of POFA 2012 ) & can be found here http://www.britishparking.co.uk/Code-of-Pr...ance-monitoring

So it can increase the distance it can go exh day, may not be applicable o a service bus, but for a coach to be able to do circa 700miles in a day and charge overnight is very relevant.

Why does an electric bus need a 1000km range? The bus may travel maybe 200km during the working day then be back at the depot for charging overnight. The truth is it doesn't have a (real-world) 1000+ mile range. That test was on a 3-mile oval track, at 15mph - no gradient, minimal aerodynamic drag. An uncharitable person might think it was a headline-grabbing publicity stunt, in which case it would have succeeded! That bus has a 660 kWh battery; to get the same energy out of a diesel engine with a thermal efficiency of around 50%, a conventional bus would need about 130 litres of diesel, which in a single-decker bus in a city environment would apparently give you a range of somewhere around 600 miles. The electric bus is actually marketed as having a 350 mile range, which therefore sounds reasonable, even if 1000 miles is marketing nonsense! -------------------- Regards,

At face value it suggested a sig improvement in battery storage capacity & technology, poss useful for getting diesels off the road or flying around the World in a solar-powered light a/c.

I would want a 500 mile range minimum, I think.
I have done 185 miles out and driven straight back in the same day. A colleague did Liverpool, almost 250 miles, in a day. So, yes, requiring a 1000 mile range isn't beyond the realms of possibility. -------------------- Cabbyman 11 PPCs 0

If we're talking about cars (which we weren't to start with), then 5-600 mile range is required if it needs an overnight charge to get you back on the road. It means a whole day's long distance driving with no stopping to "refuel". If we can get to the point where I can add 3-400 miles of range in 5 minutes, as I can by filling up my car with petrol/diesel, then a much lower range is feasible. Having to hang around for a couple of hours to add a couple of hundred miles does not yet make electric-only vehicles feasible for anything more than short-ish distance commuting. It will improve, though, as we see all the time.

A standard battery scheme, perhaps?
You know, like the calor gas bottle scheme. You pay a deposit for a battery, then when you need a fresh battery right! this! minute! you just take out the old one, give that back to the |

Which also necessitates installing it roughly centrally under the car? It's not going to be quite like having a mechanic pop the bonnet and lift in a knackered old Halfords 12-volter and you're good to go for another 300 miles. -------------------- Regards,

I quite living in a dream world, Fredd.

Never mind the logistics of swapping such a battery system. How many batteries would a charging station have to stock? The cost of the batteries alone would be pretty large, then factor in the building area needed to store them and it quickly becomes very expensive indeed

Or perhaps I might buy one of these instead https://www.youtube.com/watch?v=iEjTwsfqHOY I was looking for that video after I read your original post on battery swapping But Gawd forbid that anyone sorts out a battery swapping system.... it's bad enough with the eejits in our local petrol station who do not know where their petrol cap is, think that it is okay to wait in the entrance blocking all access or simply do not know that the pump hoses will reach the far side of their car. |

Well, it's either that or we have nuclear reactors in our cars...
