It looks to me like it’s a 70kWh pack to fill half in that sort of time at about the limits of CCS current rating of 500A. I’m not really sure what the message of that video really is?
When are you going fully electric?

So the demo was a 3C battery which is nothing new (see Tycan and Ionic 5/EV6) but the claim is they will bring a 6C cell to market in the next few months. Call me cynical but I'll believe it when I see it and I'm not convinced the cells will last long term without significant battery degradation if they are charged at their full rate regularly.
The Tycan which is one of the fastest charging cars on the market right now even even has a 'battery saver' mode by default which limits the max current they will take and that charges considerably slower.
Putting aside all the potential problems with constantly switching lots of 0.7mw loads on and off every few mins that will need to be buffered, lithium battery improvements has been a slow iterative process for many decades. Therefore I'm naturally suspicious of someone bringing something to market that claims to be able double the C rate of existing tech without their being drawbacks. As I said, I'll believe it when it see it.

Late to the party on the fast charging video but it does seem to be a bit of click bait for people who don’t know much about EV tech. Kind of a ‘look what you can get when you put 500A and 800V together’ - it’s not a real world application
In reality our charging hubs aren’t going to be doing that most of the time. Even when the charger hardware can handle it the grid connections won’t be sized to allow max rate when multiple chargers or sockets are occupied. And if you look at the new ABB 360kW chargers, operators are putting 4 sockets on them. They would rather charge 4 cars at 90kW than 1 car at 360kW, it’s better for business.

For sure, also people are complaining now about the current cost of public chargers - these hyper chargers are going to increase costs further.
I think most people are happy charging for 30-40minutes, incorporated into a break, after 4-5 hours of driving. Also, I would rather use the money saved using a normal charger over a hyper charger, and spend that on some refreshments, than be back onto the road for another 4 hours after 10minutes charging.
To be fair, even with current tech in most of the newer cars coming out now, it’s 20 mins for an 10-70% charge and you are good for another 2-3 hours. In reality that’s going to be after already driving 200+ miles / 3.5-4 hours in one hit.
Short of driving from one end of the country to another, you are already at the limits of what people actually do in the real world. Where people need to go further, they just tend to need a quick zap and dash.
I’ve never found that charging on long journeys is inconvenient. If anything more often that not I’ll take a look at the app and see the car is ready and I’m not.

The only glitch I have found is not having the charger at home. I am cool with getting back on 0 charge, but what is currently annoying is only being able to stick 80 odd miles back into it overnight.
In fact I think I may just bite the bullet here.
I've just raised a job on mybuilder to swap my consumer unit, and it seems logical to just get the charger done at the same time.
Which is the "one" I should go for? Not bothered about aesthetics.
Edit: I can see a chap on eBay selling an Ohme because he is switching to solar to charge his Tesla. Is there something I am missing?

Podpoint Solo3 cheap and cheerful and tethered for 7.5m with timed charging - or the Ohme Home Pro
Ohme is fine if you just want a normal ‘smart’ charger. It’s programmable and can integrate well with time of use tariffs.
It doesn’t do solar but otherwise it’s fine.
Make sure they read the installation instructions carefully as different chargers have specific requirements and they will have to notify the DNO it has been installed.
They’ll need to check the supply at your house can handle it, if not the DNO need to upgrade it first.
If solar isn't a requirement anytime in the future for you, then just find the cheapest charger which works with your car and has some form of timer settings (if you car doesn't have this already).
As above really.
Some have energy monitors built in if that is something you’d be looking for. I find it helpful to determine how much energy the car is actually using so I can split that out from my household usage.
The only thing I strongly recommend is to get a tethered charger (one which the cable is attached), it’s just significantly more convenient.
I’d avoid anything that relies on a 4g connection for data, you’ll end up paying a subscription for for smart functionality after the first couple of years.
Soldato
yeah exactly.
Just spotted you’ll have to pay for 4g connectivity subscription on the Ohme after a couple of years if it was purchased after March 2020. Avoid imo, just get one that uses WiFi.
To answer your second q, no they’ll not get the charger cheaper than you. If anything a full time charge point installer is likely to have a nice mark up on their installation.

I got the dumbest charger possible, no regrets.
As predicted, software takes care of everything clever anyway; the Tesla app has improved in that respect over two years, and Intelligent Octopus wants control of that aspect anyway via their API.
Tethered if you have a driveway for sure (I don't), but otherwise I don't see the point in anything smart (unless you have solar or similar).
