HOT UK DAY (reduced grid power charging rates)

[Mr Gus]

Just looked at the Tesla, only pulling 1kW @5 amps ..local grid in melt down.
Might be forced to fast charge today at this rate.

How is it for you?

Up here it is windy and blazing sunshine. If this isn't a plunge price day coming up I dont know what would qualify?

Had everything maxxed out by 11 am and now heating hot tub to use power, mental yet wonderful!

[Mr Gus]

Yon wee Bast.. (you know the rest).

Happy for you

What u got weather wise? Is it pish?

I'm beyond where I thought I could get to with pv& batteries. Tubs got a 2 stage 2hp pump and a beast of a 7kW heatpack. The 3.8kW off main array along with 4kW off battery stack is running it without touching grid.plus the 1.5kW off 2nd array is pouring into batteries to slow down the soc percentage drop.

Sorry, not bragging (much), just kinda amazed at the capability of this set up on the right day, bit of a day.

[Mr Gus]

Nah, the weather "a-la fens" is HOT, good for the harvest just setting into motion.
Currently 26+ c, humidity 60%

Shade just coming over (so cooling thank goodness).

My Scottish genes see summer sun like vampires see daylight.

The kid, having had mostly winter / alpine holidays feels the same.

Roasting hot here, 2x 22kWh days in a row with lots more sun in the forecast.

[Mr Gus]

3rd day of reduced power (intermittent) round here, the 30c is definitely a strain on the network local to us.
So much so that the wife isn't going to risk the slow charging screwing travel tomorrow.

She's got to set off from home at around 3.30 am to go to Eastbourne for 7 am & do a sign off (covid has taken a nurse down) & the car needs a solid 10 hours to fill out (at 2 kwh rate) which normally does us just fine, but cannot chance it, so has just nipped out to get a supercharge.

Whilst there is Bluewater / Dartford & another further down the road, there is a distinct triangle of supercharger network absence going towards the south coast (reasons unknown) ..likely to have to pop into Brighton office thereafter, not knowing how inflated the costs are for tesla chargers further down the road she's keen to minimise cost, even though they are work paid miles.

Watching an EV roadtrip video t'other week from Brum to Cambridge then Norwich there was a big difference in Supercharger fee's on another leg of his route.

The fella had enough battery so he skipped Wyboston Superchargers, ...Good loo's there btw) at (off top of head) £0.26p per kWh input.
Slightly further down the road (Cambridge, Trumpington) at around £0.44p per kWh input 22 miles away ..a considerable difference to a fill up.

Gus are you saying that your incoming power from the local network is reduced? How/why?

[Mr Gus]

Just based on how it is pulling from a granny plug dan, reading it off the Model 3 app for state of charge / charging rate which the app reflects.

2Kw down to 1
10 Amps down to 5

Anticipate that yet again it is just too much for the village to take & infill has resulted in several hundred new houses going up.
Power cuts imminent, par for the course here.

I imagine when we bother to fit a fast charger it will reduce by 50% accordingly too, no "smart" metering involved.

[dan_b]

So is that changing due to voltage sag on the local network? Increased demand plus reduced efficiency in the transformers because of the heat?
