OT: installing home charger for an EV

More like 34MJ/L

ITYM power (or rate of energy delivery) - So 34 x 40 / 60 = ~22.7 MW

(or ~378 kWh of energy)

(although due to the inefficiencies of the IC engine you might argue that only a 1/3rd of that will ultimately usable)

And at those kinds of loads it does not take many refuelling stations before they become a very significant and disruptive load on the grid

Its an easy problem to solve, if we have the "battery" technology. Just slowly charge a big battery at the service station and use that to charge the cars.

The same system can be used for grid storage at the expense of drivers in an emergency.

Its a big if.

Swappable batteries might work better in theory, but the practicalities would be troublesome.

It also does not get round the fact that we are close to supply limits on the grid now, any significant move of transport infrastructure to the grid would require massive new investment in generation plant.

We have a couple of Mitsubishi PHEVs. The only thing the guys who drive them like is the tax bill. In "real world" use they are no especially economical at all.

Another guy has a private BMW i3. This goes like stink. Nifty car but but the maths only really work if you NEVER anticipate driving more than

Regarding charge points look here:

Lots of options and not expensive.

The solution is easy. Everyone slow charges their cars by night.

Many quite difficult things are easy to ill informed people.
