when all the energy is being trasfered to the EVs via electric cables, equals the energy transported via petrol/diesel tankers, the mains electric supply will not handle it as demand increases

If only we had some way to know this change was coming, 10-15 years out with a steady ramp up so the electricity suppliers could plan and increase capacity. If only some other country had already gone through this conversion so we could learn from them, a Nordic country maybe. Ah safer to just stick to petrol and diesel.

One year with an Electric Vehicle:
I have had an electric vehicle for a full year now so I thought I'd give a summary of ownership / costs for anyone who's interested.

Model: Hyundai Kona, 64 kW battery, stated range of 450km.
Cost: 38k
Mileage: 23,000 km
Current Value: Only 19 cars showing for sale on carzone (191 reg). Price ranges from 34k - 38k. No sign of massive depreciation, but hard to judge as availability of both new and second hand is still low. Could all be meaningless given the economic turmoil. Anyway I view the resale value as being relative to the cost of upgrading.
Tax: €120
Insurance: No change when insurance transferred.
Servicing: €59. Serviced at 15,000 km. Really just an inspection and a wash.
Charger installation: Charger approx €600 and €400 installation, recouped €600 grant. Cheaper chargers are available but went for one with load balancing and a tethered cable. Change to night rate meter was free.
Running Cost: All home charging is done on night rate (€0.078 per kWh + 13.5% Vat = 0.09 per kWh). Average consumption is 14kWh/100km, so that's €1.26 per 100km (total cost this year = €290.) This is probably an overestimate as it doesn't include the free charging I did. Employer has now installed free chargers, so this could potentially go to zero. Also get a reduced toll rate.
Public Charging: Haven't used a public charger since November. Since charging for fast chargers was introduced, availability doesn't seem to be much of an issue anymore.
Battery Life and Range: Range changes depending on driving style. Commute to work is mostly 80km/h road and then through town at 50km/h. Just doing this, range can be around 500km during the warmer weather and dropping to 440km in winter. Some typical motorway driving brings this down to around 400km. Longest journey was a 420km round trip (no recharging). Have never run flat.
No sign of battery degradation, still able to charge to 100%.

Cheap chargers can have load balancing as well imo. Mine has load balancing, scheduling and auto peak-shaving (11kW) and I paid EUR 400.
 
With VW's new range of solid state batteries due out in 2024 it would be crazy to buy an EV now and the current technology will be hopelessly out of date.

You could say that about every single bit of technology.

If you have an EV now that can cover 4-500k and recharge on a fast charger in less than 30 min and overnight at home what will be hopelessly out of date about it?

The new solid state batteries will have a range of 1000Km and charge to 80% within 15 minutes. They are also safer. It'll probably be three or four years before they are on the market, despite the 2024 target VW have set.

that still doesnt make a car that can do 500km obsolete and most people fast charge a few times a year, and as you say lets see when these are actually available.

VW said recently 30% more capacity compared to their current batteries and they'll charge in half the time. Which is still fantastic but I doubt we'll be seeing a 1000km range ID.3, much more likely they'll just put in a smaller lighter solid state battery that will maybe bring down the cost to manufacture?

I'd agree with you though I think these are probably further away than they're letting on. They're still in the research phase and while some articles saying 'starting in 2024', others are saying 'after 2025'. Volumes are presumably going to be small to start with, so I wonder if we'll see them being priced high and put into the higher end vehicles (eTron etc) while liquid continues to be used in cheaper vehicles?

The battery life will be the big issue. At the moment the car is effectively worthless once the battery is out of warranty.
Given that the carbon footprint during production is significantly higher than IC cars their green credentials only come to the fore at they get into high total mileage. Most of that carbon footprint comes from the manufacture of the battery so these new ones may be a game changer in that respect as well.

Yeah, I'd agree and that will mean lower selling price with a knock-on devaluation of older second hand cars.

sorry what car is worthless when its battery is out of warranty?
 
I'd like to than all the people who have funded the research which is going into my next car.

i wouldnt assume a lower price to manufacture will be a lower price to sell :D. also new tech is expensive at the start, what you are talking about is probably a decade away before its 'cheap' and at that point there will be something else!
