Tesla launches the V4 power cabinet...

[Yuff]

They need to get public charging costs below ICE to encourage take up first.
Then worry about charging speeds, all in my humble opinion.
Average public charging costs 800-1000% higher then IOG off peak I find pretty irritating

For people with private driveways, paying 80p/kWh once-or twice a year is perfectly fine. That icecream you buy at the beach will be a lot more than one you get at home too! And a £20 top up is nothing when rolled into the cost of the holiday.

It is the day-to-day charging for people who cannot charge at home that needs to be affordable. This really should be AC charging wherever the car is left overnight. And for that 3.6kW is plenty for most people. It can also be 50kW charging at gyms/supermarkets and other places. But critically it needs to be cheap. This is currently the missing part of the puzzle.

I charge for free at work so don't really mind whatever the cost is on the motorway.

I do think the higher charge speeds are very beneficial, it just makes it easier and nicer. I guess it's very vehicle, regularly and journey specific.

In my experience the Tesla for all stations are full and 359kwh ones nearby will be empty because of pricing tho.

Not sure I quite agree with the ice cream analogy as getting around I don’t put in the same category as a treat like ice cream, it’s more of a necessity generally, plus I’m not sure mr whippy is 1000% more than Haagen daas at Tesco
However your other comments are bang on point and really can it be that difficult to implement……and would help massively in the take up of EVs if that is what the bivernmnet wan to achieve
When we thr MY LR , public charging should be a thing of the past, plus it comes with a year’s free supercharging so I’d actually go out of my way to find a charger

The biggest benefits I think, will be seen in America where pick ups are more common, and especially towing stuff. So bigger batts, burning more electrons, and having to stop more often for recharges.

The Cybertruck seems to be able to charge at ~500kW (at low SOC) with the V4 chargers and cabinets with recent tests. Of course this is more an edge case, but significant enough to make a difference in the US, where trailers, boats etc do get towed longer distances.

Transport Evolved (one of the older EV youtube channels) towed a car and trailer across the US with an F-150 Lightning. I recall the efficiency dropped from around 2.5m/kWh to around 1.8m/kWh.

Personally, for cars, I think the Tesla V3 250kW chargers are more than enough for me, and unless low SOC, will be down towards the V2 chargers at 125kW anyway.

Horses for courses I suppose.

Small update. Tesla seem to have finsihed their testing, and have now unlocked 325kW charging (v's 250kW) for the Cybertruck at V4 chargers. Once the support cabinets have been upgraded, that should rise to 500kW.

It may not seem important, but in the US a lot of people use large PU's for towing, which naturally increases fuel consumption, and lowers the range per charge for a BEV. So more charging stops/times will be needed. So if charging is faster, then BEV PU's become more viable for such roles. Hopefully this will apply to non-Tesla PU's too, if they can charge fast*, since they have very large batteries, some over 200kWh.

*Not sure what limitations 12V technology has on other PU's v's the Cybertrucks 48V architecture, but just hoping given the large size of some of these batts.

Edit - My bold, should have said 400V technology v's 800V of the Cybertruck.

I wouldn't think the 12V v 48V would have any effect on the charging rates as the 12V & 48V are only for the electrical ancillaries of the vehicles rather than the drive systems.

This has come about because the CyberTruck's main battery pack is 800V. and they've enabled higher voltages on the V4 power cabinets for those vehicles that have it.

The other BEV-PUs, namely Rivian and Ford F150 are both still 400V battery architectures so this won't make any difference to them.

There are some other 800V platforms out there though of course, not least the Porsche Taycan, but also the Korean GMP-based cars, so the Ioniq5/ Kia EV6/ Genesis EV60.

But then of course again in the US at least, you've got the added complication of competing DC connector types. Tesla's "NACS" and their somewhat nasty CCS design (not to be confused with the CCS2 that we have in Europe).

Thanks Dan and Fintray, big slip up by me, I'll amend my post.

I've long said that the ideal BEV needs the following:

• 50kWh battery.

• 4mi/kWh on the motorway in winter.

• 100kW charging.

If you do 150-200miles on your first hop, then stop for 15mins every 100 miles thereafter, you can get anywhere you want to get.

The car taking 15mins to charge is way more convenient than 5 mins anyway. This is because you can plug in, walk to the building, have a pee, buy a coffee, and walk back to the car in 15mins. Whereas a 5 min charge means you'd have to park in a non-charging space while you go for a pee and buy a coffee then move to a charger and wait by your car while it charges...

I frequently think of you when charging and the 50kwh/4mkwh/100kw I agree thats spot on but i fear that is a big ask in winter because of reduced batt cpacity,heating,head wind,rain. Perhaps we should say for 90% of the weather conditions ? What we need is 50kwh at 0C . This seems to be where the manufacturers are heading for in their smaller family cars as it ticks the marketing boxes/ requirements.
