Thread: Goodnight Diesel. ...Land Rover get your EV skates on!

Your K's are also reasonably low,many households would do a lot more,particularly work vehicles,that would still need charging at home.

That would be balanced to some extent by the fact that a lot of EVs are more aerodynamic than a LR and would not need as much energy to cover the same distance.
Direct comparisons are difficult because there are so many variables.

" #6 – The electricity grid cannot handle the load of all electric cars!
During normal charging at nighttime, an electric car does not use a lot of electricity.

Origin of the myth: People have fuzzy ideas about how much current an electric car draws. Many thinks that the need for installing a special home charger is because electric cars draw too much current while being charged. That might be true in the US with their 110V outlets, but not here in Europe with our 230V ones.
Why the myth is incorrect: While charging electric cars draw about the same current as comparable household appliances.
If you have driven 100 kilometers during a day, your electric car will have consumed about 20kWh of electricity. It is these 20 kWh you need to recharge back into its batteries at night. If you charge your car from 21:00 to 07:00 the next morning you have 10 hours to recharge 20kWh – that equals to 2kW of effect. That is the same effect and current an electric radiator uses.
Also, an average house uses 2500 kWh less energy this year than it did in the ’90s. All those energy efficient kitchenware you have bought since then saves as much electricity combined as an electric car uses. If you buy an electric car your household will consume as much electricity again as it did in the 90’s. The power grid managed it then, and it will manage it now as well. "

Gee! They must have really, really smart charging controllers, then! You know, the ones with AI to figure out how long you're going to be home for, so they can limit the charging rate to spread the load over the appropriate time.
Pity if it hasn't spoken to your doctors' computer to realise that there is a really good chance of needing the car for a midnight dash to the Maternity Hospital!
I wonder what the future percentage of ambulance callouts due to flat batteries will be?

As far as I understand it, the controller will deliver the maximum amount of charge it can handle, until the batteries reach around 90-95% charge, and then the load tapers off. So you would be looking at a whole lot of electric radiators! Then, after you've plugged that in, you walk into the house, turn on the A/C, lights, the TV and put the kettle on. Not a simple thing for the infrastructure providers to allow for.

I agree that EV's are probably the future, but I also feel that the reports of the eminent demise of the ICE are somewhat premature.

Just as an aside, until I got our house re-wired, the connection from the mains went through a Bakelite connector, dating back to the time when a household wiring system had to handle half a dozen light bulbs, a wireless, and (post 1950) a refrigerator. I was told by the SEQEB foreman who did the changeover (about 20 years ago) that overloading them was the major cause of fires in old Queenslander homes. He said their maximum rating when new, was often as low as 10 amps! At that time, he estimated that around 70% of the older homes in Warwick (population ~10,000) still had the old connectors fitted.
