Yup, that is completely plausible and would reduce the costs for gridserve to install. I’d expect the costs to install greatly outweigh the material cost of the additional capacity needed needed to accommodate the extra Tesla chargers.

Gridserve Charger Sites in UK [megathread]

I haven't been to Braintree, but here's Trumpington:
which is the same as you posted earlier for Norwich.
So the only reasonable assumption is that this is a continuous rating and it is exceeded for short periods.
There's no reason to suppose a fixed percentage, as Tesla have temperature monitoring on both sides of the interface (ie. in the car's socket and in the connector on the end of the cable). They've long been doing this with the V2 superchargers, where the current delivered is much more than the nominal rating of the type 2 connectors (and you see the charging rate decrease if the connector gets warm, as they do when worn/damaged).

The usual electrical continuous current value is 80% of the rated cable capability, but of course that’s without water cooling. Yet 'Rated' is used for normal maximal operational use, within a 'Rated range' typically 10%. The 680 A needed to sustain 250 kW with a 100 kWh pack at low state of charge is quite a leap above (60% in fact), but may well have been established empirically through sensor acceptance on both sides like you say. Hopefully someone can just say they charged above 200 kW when at one of the Norwich superchargers to know for certain. Plaid S for example from 6–34% SoC sustains 250 kW. Perhaps the labels themselves should say Nominal instead of Rated, a US electrical parlance thing?

Is there any reason to expect Norwich's charger spec to be different to any of the other V3s?

Power sourced from the first Compact GridServe site, see earlier post of mine.
Highest I've heard to date was a Zap-Map comment of 225 kW peak from a M3LR.

I swung by Wetherby Services today and had a quick look at progress on the 12 Gridserve chargers. I saw no evidence that any Tesla chargers are going to be installed at this site which is no surprise when Ferrybridge further south and Harrogate to the west have recently opened.

Haha. I’d happily have a nice short block V8 as a coffee table. Not sure an drive motor from an EV will be as photogenic or evocativeOh and they have a funny piece of furniture for an EV charging station!View attachment 796078
Funnily enough I saw this yesterday at Braintree and it looked ace, even the wife thought it was coolHaha. I’d happily have a nice short block V8 as a coffee table. Not sure an drive motor from an EV will be as photogenic or evocative
Had the pleasure of using my first none Tesla SC since 2017. All I can say is WELL DONE Gridserve. It was a pair of chargers that use to be run by Ecotricity, the difference in user experience couldn't be more different.
No stupid apps, contactless, clear step guides, long cables, and I believe the chargers could do x2 cars at once now, in addition I think the cost of charging is cheaper than Tesla SCs.
What Gridserve needs is government support to expand their installs at existing Mways services from the x2-3 chargers at each site to 6-12+. Given nearly all Mway service have chargers inplace already from previous Ecotricity install it surely much be much easier than having to install brand new sites like Tesla have to do. Between Tesla and Gridserve they could really sort out Mway based DC rapid charging in the UK as long as they can get grid connections.
Eitherway, its really encouraging progress on public DC rapid charging....however as much as I was impressed with the new chargers, having to pay for DC rapid charging was a step too far. I gave in after watching the cost tick over £10, unplugged and headed for the nearest 'free' Tesla SC

Two new Gridserve sites at planning stage. No sign of any tombstones.

The rating on the supercharger stall is only a part of the overall picture I think. The stalls are basically just a holder for the cable, the label on them is what they can handle, rather than what they output. It’s the white cabinets which give a clue to what’s being generated.
Here’s a Heathrow Hilton V3 cabinet.

Moving it to vacuum could be an issue unless you have an engine hoist as a hatstandHaha. I’d happily have a nice short block V8 as a coffee table. Not sure an drive motor from an EV will be as photogenic or evocative

I’ve actually got one. It’s a 3.4 litre V8 Gibson Tech from an ex LMP2 Le Mans car which had a catastrophic fail on cylinder no. 4.Moving it to vacuum could be an issue unless you have an engine hoist as a hatstand
It’s a nice table and pretty light being alloy. I’ve not weighed it but it will be less than 20 kg.
An iron block would be a lump to shift.

GridServe’s prices are two-tier at the Norwich Compact hub, with 39 p/kWh for 7/22 kW AC & 45 p/kWh for both 100 kW ChaDeMO and 350 kW CCS. Elsewhere on their Electric Highway network it’s also 39 p/kWh for up to 60 kW chargers.
