Taycan CCS to NACS adaptor for fastest charging on Tesla Supercharger

[drolling]

I bought a Lectron CCS to NACS charger for my new to me 2021 Taycan CT 4S but when I charged it I was only getting 44kwh. Anyone have a better Adaptor brand they recommend for the fastest charging times at the Tesla Superchargers.

Thanks in advance!!

Make sure you have the optional 400V 150kw onboard charger. Otherwise you are getting 50kw max regardless of your adapter.

Don’t know whether it will be any better, but Porsche is now making available for purchase their own CCS/Tesla adaptor. You can soon order it for $185 in the Porscheusa.com online store. I tried to order one and was told they are not yet available, but that I will be notified when they are. BTW, 2025 and 2026 Taycans get the adapter free.

You likely don't have the 400V/150kW option. In 2021 everyone was advising against it as useless in the US. As said, without it your 800V car is limited to 50kW on the 400V Tesla V3 stations. It is possible that in the next few years more of the V4 stations will convert to the higher voltage and should charge fast. Note that the adapter is just a metal connector, it doesn't affect the charge rate. Both the Lectron and the Porsche one are rated to charge at much higher amps than is possible for a Taycan on a SC. And sadly, the 400V/150kW option cannot be retrofit.

the adapter(s) do not limit charging speed - they can not - they are very simple devices that just passively pass electricity through to the vehicle.

charging speeds are always affected by various factors outside your control

Tesla Superchargers are 400V DC superchargers - maximum charge speed of a 2020-2024 Taycan at any 400V FastDC charger are affected by the type of 400V DC Booster installed at the factory - there are two 400V Boosters possible on a 2020-2024 Taycan

• 50 kW 400V DC Booster
• optional 150 kW 400V DC Booster

consult your vehicle's build sheet to see which your Taycan has installed. If you do not have 150 kW booster, your maximum charge speed at any 400V Fast DC charger (like superchargers) will be 50 kW. Hint: if the 400V/150 kW DC booster is not listed on your vehicle's build sheet you have the standard 50 KW booster.

2025 and later Taycans, and all Macan's EV's have taken a different approach to 400V charging and no optional booster is required for 150 kW/400V charging support…

this article from Porsche is very helpful for all things charging…

That could be the problem.

Is 400V/150kW standard on J1.2 Taycan??

I was able to buy the Porsche adapter at my dealer in Newport Beach, CA even though they were sold out on line.
That being said I purchased the adapter as an additional charging option when on long trips which I seldom do. When I do if it takes me an hour to charge my vehicle from 40% to 80% then that’s all I can expect.

different approach - but effectively yes…they "split" the pack for 400V charging and achieve 150 kW maximum charge rate…

https://www.batterydesign.net/porsche-macan-ppe/

If the station is using 400-volt technology, the all-electric Macan uses ‘bank charging’ for the first time, whereby corresponding high-voltage switches (gates) are automatically switched in the battery before the actual charging process begins. This effectively splits the 800-volt battery into two batteries with a nominal voltage of 400 volts each that can be charged in parallel on one 400-volt charging station without an additional HV booster. If necessary, the states of charge of the two battery halves are first aligned before they are charged together.
Porsche Media [1]

The split pack approach to allow 400V charging is a move away from the fixed 800V pack in the Porsche Taycan that used a DC-DC to enable 400V charging. This is a significant change in architecture and the split pack approach brings additional failure modes. Hence, this is a surprising change and it would be good to understand the issues face with the Taycan and hence this change in approach.

Two main issues with split charging:

1. as soon as aging happens, the half packs end up having different internal resistances and capacity of the cells, which in practice means that when charging the pack with a given current, the current will not be split in half, i.e. there will be asymmetry on the two half packs in terms of state of charge, heating and so on, especially when doing fast charging.
2. contactors: keep in mind that it is not only a matter of turning ON/OFF some switches, which also adds failure modes to be diagnosed, and potential new short circuit failures in case the relays gets stuck transitioning from one configuration to another (series / parallel); for this 2nd point, there is also the issue of monitoring two half packs voltages, and currents, so the sensors have to be doubled (4 current sensors instead of 2, and many more HV sensing points).

This is not a bad solution, just that it adds a number of engineering challenges.

I had one of those adapters, and it killed my charger in the car. It's only a passthrough, so there is no communication with the charger. They fixed it, but said not to use it again. I would imagine that the Porsche one talks to the charger.

it does not - these adapters are all passive and simple pass through devices

this is the porsche one that they are simply rebranding

https://ev-lectron.com/products/lec...0a-1-000v-compatible-with-tesla-superchargers

there is nothing an adapter can do to kill your on board charger

 

[FIX]

Maybe the new charger is fixed then...

 

[FIX]

The dealership said that if the AC breaker kicks while charging, it may have killed it. They paid for the new one so I figured it wasn't a lie...

dealer BS “ac kicking in that killed it “ utter BS - the AC power pins are not even present in these adapters

really really made up sh*t - new record for clueless

the fuel filter removed all the octane which is why your 13v battery died because the alternator was not spinning fast enough - we fixed it for you!

lets spew words together to make it sound like we know what we are talking about

dealers

 

[FIX]

The actnitagauzer defribulater converter always goes into “rescue” mode when it senses a differential between the activator and the snub sensor.

The Tesla charger (home version) is AC not DC. They paid for it so I’m happy…
