Dissapointing tacan DC charging

[jonjon808]

I’ve been an EV driver since 2016, so fully drinking the koolaid, but it is a shame that there are so many variables than can affect DC charging speeds. I regularly use Chippenham Ionity and almost always get 260KW as I will have the charger set as a stop in nav, will be less than 20% SOC on arrival and will often put it in to Sports+ mode for the 10-15 mins before arrival to get a bit more heat in the battery. Cobham Ionity is another matter and regardless of the car state, I’ve never gone above 160KW.

The variability is beyond just the temp and soc in addition to the charging station. Today, I tried 4 different chargers, with 15% Soc and a temp of 92f, couldn't get beyond 52kw. I suspect that the car was asking for far less than it could have. Taycan next to me was pulling 170 on a EA 150 when this loaner my23 taycan couldn't do more than 45kw.

I think that there is also something temperamental with the car itself.

Ive had an Audi EV for some years. From plug into a commercial DC port it ramps straight up to 150kwh charing right the way to 80% full before ramping down in steps for the final 20%.

Same with a Taycan and its no faster then 100kwh charging for much of the range, The advertised >200kwh charing seems to be for a relatively small % of the battery. So if you rock up to a charger with say 50% full, it does not really charge that quickly at all.

If you start at a very low SOC you will probably going to see the orange turtle on your dash ( due to overheating). A trick I learned recently is to put your car on Sports Plus, it brings the fan on earlier.

Hi. I am looking to get a CPO Taycan and am seeing the two different options offered by Porsche, the 19.2 kW AC On-Board Charger and the On-Board 150 kW/400V DC Charger. The dealer salesman didn't seem to fully understand these when I asked him how each works.

My home charger that I use for my Cayenne hybrid is an AC to DC converter. Isn't that the same thing as the public chargers? Aren't all public chargers, fast, ultra fast and everything in between all similar? using AC to DC conversion? So under what circumstance would I charge a Taycan with AC current (no conversion)?

The On-Board 150 kW/400V DC Charger is required to charge the Taycan to 80% in the roughly 30 minutes I see touted online?

All Taycan have both AC and DC onboard charger.
11kW AC and 50kW DC under 400V or 270kW DC under 800V
Options are :
a boost for AC charging up to 19kW
a DC booster from 50kW to 150 for 400V chargers

Home chargers are usually AC chargers (mono phase 7kW or Tri phase 11kW or 22kW)
Old Street chargers are usually 22kW AC but who will want to use them?
DC superchargers will provide from 50kW to 350kW.
5 to 80% SOC in 22 min may any be achieved on 300kW DC chargers.

150kW DC booster option should be standard while 19kW AC is probably useless these days.
I hope this helps.

How can you tell if a high speed commercial cgarger is 400V or 800V

 

[allroadusa]

300kW+ rated chargers are 800V

The 150kW DC option is not a charger. Rather it is a voltage booster from 400v to 800v which is the native voltage of the battery and architecture of the car. The standard 50kW onboard DC charger is 400v and to take advantage of 150kW DC EVSEs which are 400v the booster makes this possible. To charge the Taycan you must get to 800v.

All charging is performed in the car as this is where either the AC or DC charger is located. The wallbox, public AC or DC charging points (EVSEs) are not chargers.

DC EVSEs supply DC direct to the car's DC charger where no conversion is needed and therefore quicker to charge. AC charging requires the conversion first before the battery which is native DC can be charged and hence takes longer.

Beyond this the Taycan additionally has a 270kW 800v DC charger which enables speeds up to this maximum from either a 300kW or 350kW EVSE (all of which are 800v).

19kW AC is probably useless these days.

In UK/Europe 22kW is quite frequently found in car parks, hotels and city centre street chargers, where three-phase power is available. See the example map here, filtered to show 22kW only. There are even more in Germany and France than in the UK.

On a road trip 22kW can be very handy, eg charging in a city car park while doing some sightseeing or having a meal.

Currently all Tesla superchargers (only some of which are open to other makes) are 400V — so if you didn’t spec the 150kW option you are going to crawl at 50kW max, and annoy the other users. There is a possibility for Tesla to go to 800V for its V4 superchargers but no incentive for them to do so yet.

By looking on the metal plate around the back of the EVSE somewhere. A few say on the screen (I found an osprey that did). And the newer ones are generally 800v apparently.
But no way of knowing from route planners or zap maps etc.

Remember that you must have the Taycan 22kW onboard charger option to take advantage otherwise you will be limited to 11kW as this is the max of the standard AC charger.

They aren't chargers!

They supply electricity only.

The car has the charger for either of AC or DC charging.

Anything over 150kW will almost certainly be 800v. MFG 150kW EVSEs are 800v.

As pointed out there is no easy way other than looking at the device asset plate or the display.

Plug in and hope (assuming you have the 400v DC booster option installed).

Shame on the dealer sales people. All they do is putz around and look at their phones all day.
The simplest interpretation is below without many ifs and thens and what nots. Both are not critical or deal breakers if you are looking at a CPO. However, if 2 are the same , then go with the one that has the second one on this list with more potential benefit than the first.

1. Standard Equipment on the Taycan AC (for home) is 11kW with 19.2kW is an Option (see below) that is expensive and needs very high amp line at home as requirement, EVSE that supports high input/output, with very limited benefit of charging faster at home.

2. Standard Equipment on the Taycan DC (for public charging) is 50kW on 400V chargers with 150kW as an Option below that is not expensive with benefit of using Tesla public chargers when they open up to charge faster on the road. This has nothing to do with standard Taycan charging capability of charging at 800V chargers at up to 270kW (with PB+ battery) at Electrify America or EVGo.
