noob Taycan EVSE question

[masmole]

I don’t have my Taycan yet but I did go ahead and have an EVSE installed in my garage. It’s an Autel Maxicharger (hardwired version) and I had my electrician hook it up to a 70A breaker in order to get the maximum 50A charge rate the Autel unit is capable of. But I just realized the Taycan can only do 48A charge rate 11kw. Can I damage the Taycan if I charge it with my 50A 12kW EVSE as is? Would I need to turn down the max charge rate setting on my EVSE from 50A to 48A or will the built-in AC charger in the Taycan “auto-adapt” and charge only at its 11kW maximum despite being fed by a 12kW EVSE?

you're fine - if you plug any EV into a higher capacity EVSE the car will only pull what it can use - an EVSE does not "push" electrons into an EV - the vehicle "pulls" what it can handle.

there is no issue.

thanks!

I would be interested to know why you installed a EVSE? I am ordering a Taycan and plan to just use the PMCC that comes with the car. This uploads charging stats to MyPorsche I believe and figured it better to use the PMCC anyway.

There are many different EVSEs on the market. Each one has its own particular characteristics.

In North America, the Porsche PMCC does not come with the car and is one of the most expensive EVSEs you can buy. There are much better and less expensive EVSEs on the market.

In Europe, if you get a PMCC for “free”, then sure, use it. In North America there are better choices.

The EVSE has three main purposes: it “tells” the car how much current (amps) will be delivered from your house to the car (this can usually be set with either switches inside the EVSE or via software), it has safety protection to prevent electrical shock (via its built in ground fault circuit interrupter), and it has the cable which connects to the car. All of the actual charging circuitry is in the car. All EVSE do these three things at a minimum and are necessary to charge the car.

PMCC in North America can suffer from heat issues when run at 50A so much so that Porsche rolled out a software update globally to all PMCCs last week. The impact for North America was to reduce their ampage by half to 20A which effectively reduces the power to 4.8kW (standard PMCC was 9.6kW) and hence why many are hacked off. This did not impact Europe or elsewhere.

So you are right, charging stats will be auto loaded to your My Porsche account once you hook up to WiFi.

No need to worry about another EVSE and very lucky that the 22kW PMCC version is supplied as standard for the French market

Yes PMCC included in France. I'm also probably going to have to go for the PHEM as an upgrade to 3 phase on my very old house is going to be silly money. I believe the PHEM and PMCC work together.

the PMC+/PMCC for the North American market are substandard products not worthy of the Porsche badge - and recently due to poor design choices Porsche has had to reduce the charging capacity from 9.6 kW to 4.8 kW.

also the PMC+/PMCC being "mobile" EVSE's are limited to 9.6 kW and therefore can not achieve/match the Taycan's maximum charging speed of a 11 kW - this 9.6 kW limit is universal for all mobile EVSE's in North American due to building codes that limit plug-based (vs. hardwired) devices to 50 amp circuits - if you want more than 9.6 kW charge rate your EVSE MUST be hardwired…and therefore not mobile.

Viable and efffective alternatives can be had for as little as $200 USD in North America vs. Porsche's w/order cost of $1120 USD or over $3200 USD purchased separately…
Also the Porsche home energy manager is not a thing in North American so there is no advantage to the PMC+/PMCC for integration with that device.

There are a number of reasons to avoid the Porsche EVSE offering for North America - elsewhere the calculus is different.

Not easy for me either being in France. Houses are limited to 12KW 60A in single phase. 100A in the UK. So I am forced to go 3 phase if I need more and pay the electricity companies a lot of money to make the change.

So my current thinking is staying 60A single phase and having the PHEM to manage the load. Overnight I should get 7.2kw to the car and the PHEM will throttle it back when I have too much load in the house such as when I have the electric radiators, washer etc on. This means cost will be 552 euros for the PHEM and the rest is wiring up the garage so labour and cable costs.

I don’t know for,France, but in my country it’s not for free at all.
I simply didn’t know that there are any alternatives, and sales guy suggested it.
If i’d found this forum before, I’d buy Juice Booster.

Nothing is ever FREE with Porsche, but here in France it in in the standard specification and included in the overall price. Zero cost option.

 

[B61]

It was an option here for about 1600€.

Mine was 'free' 2 years ago as there was a supply shortage with the PMC+.

In case you may be unaware but many other EVSE's will provide WiFi uploads and all record/post charging sessions on their app/online site etc - my ChargePoint Home Flex does this better than many and better than the PMCC imo tying automatically (but still customizable) into my local electricity provider's rates etc. - super easy summaries of day/week/month/annual costs etc.

I just had the same Autel Maxicharger 50 Amp installed (hardwired) and it replaced a Tesla Wall Connector (2nd gen). I like it so far and paid less than $460 for it when it was an Amazon Lightning Deal. Very easy to change the amps in the app and I set mine to 48 amps. Only EVSE I know of that connects with Bluetooth, Wi-Fi and ethernet.

Our other EVSE is a ChargePoint HomeFlex 50 amp and it's also a very nice unit, but much more expensive. The ChargePoint Home Flex replaced a Schneider 30 amp EVSE we got in 2012 for a Nissan Leaf. Back in those days some 32 amp EVSEs were close to a $1,000 !!
