We may be in need of a 7kW EV charging point in the fairly near

Anyone got any advice on makes, installers (I assume it's not DiY to

To qualify for the grant they have to be installed by someone on the

what to ensure? It's all new to me.
There are specific requirements about earthing for EVs, possibly
requiring a separate earth rod, particular RCBO type and carefully
keeping apart the house earth and car earth.

There are now several chargers that do all the earth handling
internally, and might be OK for DIY e.g.

Look at a couple of EV videos on youtube by John Ward or Artisan
Electrics.

You probably don't need one. Don't be taken in by the salesman, A
slow overnight charge from a 13a socket is all most people need.
No-one runs their battery to depletion, you only put back in what
you've taken out. Slow charges prolong battery life too. Work out
where you're going and power and energy needed. An overnight slow
charge typically gives over 100 miles of range.

so, my 400 mile, 7 hour, journey takes 4 days in an EV?

"The Drive editor-at-large Alex Roy and the cars owner, Daniel
Zorrilla, drove a Tesla Model 3 across country from Los Angeles to
New York City in 50 hours, 16 minutes and 32 seconds, setting
another Cannonball Run record for an electric vehicle."

"The pair drove approximately 2,860 miles from Redondo Beach,
California to its final destination, the Red Ball garage in New York
City, at speeds ranging from 120 to 140 miles per hour.

'We had a spotter plane flying overhead looking for police, rating
us the police locations, night visions, binoculars, scanner, its
like a military operation,' Roy said.

Roy and Zorrilla spent just over $100 in total charging costs and
kept the heater off in the car to save battery life. "

2860 miles / 50.25 hours = 56 miles per hour averaging in charge time,
while driving well over that speed on the
highway (120kph to 140kph)

Using those kinds of numbers, your 400 mile trip takes 8 hours or so,
just rounding a bit.


if there were guaranteed working & free charging points and if I had a
Tesla. I couldn't afford the spotter plane

Drones with HD streaming cameras are really cheap these days :-)
