“Battery EV” vs “Hydrogen Fuel cell EV”

Nusa:
Tesla is planning to open up their charging network to non-Tesla cars, which will be a game-changer for the lesser brands. They're starting a pilot program in the Netherlands to see how it goes congestion-wise.

Not across the whole estate at once though. A typical UK suburban estate might supply 80 properties per phase from a 500 kVA transformer. This might be as 4 to 6 three-phase cables radiating out from the substation with individual cables fused at 300-400 A each. That transformer might thermally cope with 600 kVA in cold weather and maybe 1 MW for an hour.

Mass EV home charging is a solvable problem, but it will need a combination of infrastructure upgrades and smarter charging, e.g. load management according to local substation load and temperature. The DNOs are aware of this, and are working on it. Well kinda, they're complaining about the cost and I suspect hoping the UK government will pay for it.

btw I was looking at the EV charging tariff and I think most of the continental European countries have similar
it offers at least 8 hours (as they say) between 6pm and 8am of very cheap electricity (even a little cheaper than classic peak/off-peak)
so if you let the utility company say when and how fast you are charging, you get electricity at about 50% of the common price

Yup.  My electricity is cheap from 8.30pm to 1.30am.  I get it at 5.5p/kWh, normal price is ~15p/kWh.

I actually manage to shift about 45% of my demand into the off-peak period, saving ~£400/year in electricity cost.  Since the electricity is cheap for whatever.  So tumble dryer, dishwasher, and car all run in this period, if needed.  I actively avoid running them any other time and plan the washing machine usage so I can use the off peak electricity as much as possible.

Unlike many here I actually own a BEV with 220,000km on it after 4 years. Sure I charge at home , on night rate , because it’s a 30 kWh  and I need all of it available the following day. It starts at 1am and finishers around 5 :30 am on a 32A ( sorry re the kW  mistype) EVSE circuit.   My dishwasher and washing machine run every night from the start of night rate till 12:45 am. My hot water heating begins after the EV has finally finished. If I needed more range the reality is I’m running out of time.

Today as most batteries are relatively small. , home charging is of course feasible. But as batteries increases towards 100kwh and beyond and as we see bigger and heavier BEVs. I don’t see domestic capacities being sufficient , leaving aside the DNO issues.

As smart chargers are rolling out I’m seeing 24 hour rolling rate changes. This is no good to me , my car charging time period is fixed as are many others. Electricity providers know smart tarrifing is for their benefit not yours.
