Re: Shell EV Charging Hubs replacing petrol stations?

A tank full may well be cheap but taxation is inevitable, probably on a milage or road charging basis, maybe both. There is every reason that oil companies will establish charging hubs on existing sites, they will be able to buy power far cheaper than domestic customers, they have the existing site...

Re: I Don’t Rapid Charge often, but.....

Wanting to be even handed in this debate there is a great deal of trial work being done using hydrogen powered vehicles in zero emission environments, much of the data is conflicting with no economic conclusions. For urban bus operation comparing a diesel bus running on taxed fuel with untaxed fuel ...

Re: I Don’t Rapid Charge often, but.....

Liquid hydrogen does indeed have an energy density 10 times that of gasoline IN WEIGHT terms, but In volume terms you need 5 liters to equal the energy value of 1 litre of gasoline. To remain liquid it has to either be cooled to minus 250C or compressed to 5000psi in heavy cylinders, wether the ener...

Re: CHAdeMO to type 2 adapter for the I Pace

Are there many Chademo 50kw chargers in the UK that don’t have a CCS 50kw plug as well. The problem I see is inactive chargers.

Re: I Don’t Rapid Charge often, but.....

I’m sorry to be very skeptical about Hydrogen, if only it could be combined into an energy dense liquid fuel, then it would be much more practical and even useful for aviation. BEV trucks was mentioned and of course Tesla is developing just that, recharging will have its challenges, in that case cha...

Re: I Don’t Rapid Charge often, but.....

Nothing has 98.6% efficiency except in dreams, to be useful for a moving vehicle hydrogen has to be compressed into heavy cylinders and liquified at 5000 psi, even then it has the energy density 1/5 of gasoline, then you have to convert it back into electricity with a fuel cell which at present is 4...

Re: I Don’t Rapid Charge often, but.....

The grid has 20% + extra capacity now and upgrading is being done year by year, there is not going to be a problem with supply it’s the charging infrastructure that’s lacking. Is there really going to be 8m cars on the road in 30 yrs time ?, as ICEs are phased out there are going to be a great many ...

Re: I Don’t Rapid Charge often, but.....

“In the UK, housing estates are built with sub-stations that are capable of delivering an average of no more than 5kVA / home. What is going to happen when everyone has an EV and charges it at night?” With all the energy saving measures that have been taken in recent years this sounds correct, so if...

Re: Jaguar Netherlands: Newsletter 17-02-2020

There is a slight error in translation here seats at 3.7kw on a 12 volt system would consume over 300 amps. May I suggest a more realistic 5 amps per seat - 60 watts even then there would be a thermostat to switch off at a certain temperature
