Col ha ha, fuel light.. forgot about those :) on the fumes ~ coast down hills, good savings lol
TaskMaster: The Fuel Light, not the cab light! I'm always driving around with no fuel in the car! I wouldn't trust myself to make sure it's charged!
Col. ."I'm bad enough for driving around with the light on as it is"
eg Tesla 85kw .... leaving the interior light on would take something like 1.94 years to deplete the battery :)
Are you really saying that the connectors to the Tuscan from the charging point when trying to load up for 500m round trip in a short time is going to be made of aluminium, or copper? I ask because the copper industry is pretty certain they will be copper. If copper they are going to be pretty heavy and since car drivers range in size how will that work?
Another battery/fuel cell example ...Daimler and Volvo now have a €1.5bn joint venture for fuel cell development ....https://www.carsuk.net/volvo-xc90-get-hydrogen-fuel-cell-range-extender/
An example - https://www.daimler.com/products/passenger-cars/mercedes-benz/glc-f-cell.html
Battery fuel cell hybrids will be part of the market including self charging hybrids providing a battery reserve when needed or a fuel cell reserve when needed. Some models will gave large batteries others small batteries depending on consumer requirements.
I was referring to the copper required to supply multiple charging points up and down the country where upgrades are required in order to service them.
eg. a typical park & ride facility loaded up with 150kw charges, or terraced streets with one outside each house. What upgrades would be required to service all these chargers? I don't have the detail, I'm just a sceptic that this is going to happen.
I just can't see it I'm afraid. If you've got a drive and you don't need range then a BEV is great solution.
I think a likely outcome is Hybrid, a BEV with a fuel cell range extender, so you get the best of both worlds.
I for one won't be purchasing a BEV, I'm bad enough for driving around with the light on as it is! If I can't stop & fill-up in 3 mins, then I'm not interested. It's a backward step.

"The copper required to supply those bad boys"
Col Bilbo, if you're talking about supply to the charger, then conductors are aluminium not copper, three phase 11kv then 415v ~ again huge conductor sizes aren't necessary.
Col...dont know if you are refering to copper on the charger or the network ?....... 500kw for the car isnt necessary imo, 150kw does the job long distance, 50kw if you're taking breaks which you should...... For short journeys around town small BEVs are perfect, simple to manufacture and will be cheap when they stop jacking up prices .....if you're talking HGV, Busses etc then obviously this is where H2 wins out.
Copper dimensions @ 150kw 800v ~ eg porsche taycan) charging tether would only be 6.55mm dia conductor...liquid-cooled cables can be used to reduce temp for higher current.

I think he means 500 Kw chargers that are now being talked about. The copper required to supply those bad boys.
Agree with bilbo, can't see it en mass. What I simply can't get past with battery electric is how your average Jo is supposed to charge their car... When they live in a flat or a Lancashire terraced house.
I think bevs will remain, for those who can charge, but may be supplemented with a fc for range.

I've said it before on this forum, the thing that bothers me most about rapid charging is the connector. Electrical connectors are always the weak point. They have limited lifetime mating cycles. If you get even the tiniest resistance and you're trying to pass through 200 Amps (or likely even more) then the power lost and the heat generated can be huge. Imagine if there were 0.1 Ohm resistance in the connection...at 200 Amps you'd only lose 20 Volts across it, but it would have to dissipate 4000 Watts as heat...that's more heat than your kettle generates. I have no idea how they keep any of their connector resistances down, but I'd have thought you can't allow more than about 100th of that to occur. Don't get me wrong 700 bar for a hydrogen refueling station is scary too.
Bilbs 500mph ? copper weight where ?
Just think about the cable size required for rapid charging for 500 mph, the battery may or not be the problem but the weight of copper is awesome.
But battery tech is on the verge of rapid charging with 400-500 mile ranges so I wouldn't put that down as a usp
I 100% agree dude
The battery electric car is a cul-de-sac that we should be avoiding. It has been sold to our politicians as a quick fix without any deep analysis of the problems, of which there are many.
The only viable, long term solution is cars powered by Hydrogen Fuel Cells because they have the range of our current vehicles and take hardly any more time to refuel.
