In the Taycan there are only two battery sizes and the all Cross Turismo's get the larger. the difference between turbo S, turbo 4S and S is the number of motors and their power.

With range, a big issue with EV's I suspects an S or base with the largest battery will be the biggest seller.

Winder what affects this will actually have on battery longevity?

No electric Macan yet? How about an electric 911?

Hi,

Now given I have been involved in the design and installation of the ABB Terra 175 High Power chargers on a No of filling stations across the UK, Note the 175 relates to Peak Output rather than the 160Kw Continuious output that one should really look at. The 360 units that the link highlights will likley be 360 relates to Peak Output rather than I suspect 320Kw Continuious output.

Now reading the small print, says up to four EV's charging at a time, so they will not all be able to charge at 320KW rather more like 70Kw each after all the total output cant exceed the max input. So if a motorist sees "Oh great a really fast charge at 320Kw and will only be there fifteen mins or whatever, they will be very dissapointed as at 70Kw charging time will of course be 25% lower".

Motorists also need to remember likley only the very latest cars with the latest battery tech could charge at those rates being advertised, so if you have say a four year old Nissan Leaf no point in you even thinking about getting the speed benefits of these. EV Chargers and EV vehicles when plugged in to each other basically do whats called a "Handshake" the charger tells the car what type model it is, software version and charging cpabilities, the car then tells the charger what type of battery it has, what software its running and basically the charger then limits its output based on what the vehicle battery can take.

People also need to mind that these super fast chargers are meant to be for top ups as people go on longer journeys, not a daily occurrance. Like your own smart phone, you should never fast charge it all the time as it decays the batteries storage ability far quicker than the normal trickle charging that should be done to Maximise the batteries life. So EV Manufactuers really do expect you to charge overnight on a 7Kw charger or slightly larger not use high speed chargers all the time.

I know the cost of installing one of these, and the work involved in maintaining these machines thats presuming the local electricity supply company has spare capacity in the local area.

EV Motorists had a laugh last couple of weeks with fuel shortages with ICE owners, also they dont pay any fuel duty which the exchequer has seen drop in revenue as people swap to EV, but they really dont know what is about to hit them.............................. NO Such thing as "Free" Exchequer has plans to get fuel duty income back to pre covid levels and no matter what "Fuel" your vehicle runs on, you will be paying for it without a doubt.

At the moment one of the biggest issues seems to be just how many of these chargers don't work when people try to use them. Presumably because of the power involved servicing them can be a tad dangerous if you don't do it properly and I would assume there aren't all that many certified engineers to fix them just at the moment. A petrol pump is pretty straight forward and usually the only thing that happens is that occasionally they wont read your card and you need to stand in a queue of idiots doing their weekly grocery shop in a petrol station (that a whole different middle aged man rant)

OmniCognateSnr,

You are pretty much spot on, lots of issues with especially the fast chargers are due to power issues. So one example being if you have a bank of say ten chargers all 160Kw, the overall power availible may not be 1600Kw 24/7. So local power company may put restrictions on on Max demand at certain times of the day, so operator can set it up so all ten machines now have lower power outputs, or they automatically put say five completely out of service, thus still leaving five operating with outputs as displayed and 160Kw.

By far the biggest issue is software compatibility, both between the chargers and cars, any little blip and they just wont talk, also the vast majority of these chargers have 5G connectivity to some sort of HQ, some may have a ethernet connection as machines poll the sales revenue all the time, but also like our modern cars new data packages are sent to the machines, which can be details of new EV's coming into the market etc Im sure you get the idea. So basically the charger locks up, HQ will try a soft system reset remotely but if that doesnt work a technician in a van needs to go out and do a hard reset. As you say liqued fuel dispensers are a lot easier and simpler and far less breakdowns.

I've worked in IT for most of my life (very large corporate Facilities Management Systems). Keep it simple is always the best maxim to follow. I assume at some stage electric chargers will be the norm but by the sound of it there is going to be a lot of faffing about until standards are agreed on. Even then, the more complicated you make things the more they are likely to go wrong. To quote, or possibly misquote, the late great Scotty, "the more you complicate the plumbing the easier to it is to stop up the works"

We petrol addicts have had a rough couple of weeks. Looks like the electric people may be next though:

One of the pop up adds on a site was for a Peugeot EV now having had and loved a 206GTi many moons ago I clicked on the add.

206 EV range c120 miles, come on Peugeot that is useless.

Similar with the Mini EV c150 miles is quoted.

Those of us one car families are simply not catered for in any reasonably priced small EV at present that has a range that will get us a reasonable distance without suffering from range anxiety.

100% agree. That’s why I feel Tesla is the only real option for electric cars, even with all their “issues”.
