EA 350KW unit speed of charge declined by 50% after the software update

[Gambler]

So annoying now I'm getting only 55kw/min, and the free 30 minutes charge is invalidated. I have to spend an hour to bring the juice up from 17% to 80% SOC. I recall the speed was @120 kw/min before the update. I read in another form that it became the norm after for wire/cable heat nonsense. Also, only 2kw/min at-home charge it used to be 4-5kw/min

Something’s not working right. Bring your car to the dealer for service. I was charging yesterday at ~160kW yesterday on a 150kW charge point at EA. My car is fully uPdated.

Very likely the charger, try a different charger or even a different site.

this is not the software update - there are many many many reasons a particular charging session may not be optimal rate - most/some of which have nothing to do with the car.

FACT: unfortunately there is insufficient information provided by the vehicle and/or charging/stall to diagnose what part of the whole charging system was/is the bottleneck at any given moment - there simple is not!

I also doubt the dealer can/will diagnose anything with regards to charging speed until it's nearly 100% consistent…again it's because it may have nothing to do with the car, but it may have simply been circumstances on that particlar day at that particular site at that particular time at that particluar stall with that particular charging cord…yes those are just some (not all, some) of the variables involved in fast charging.

Example: Porsche Monterey has two shiny new Porsche FastDC chargers - if you charge in the morning you'll get full full rate (260+ kW) - but if you charge in the afternoon you may be lucky to get 50 kW - why? Because they have onsite batteries that when they are full can assist the chargeing stall to provide max-rate (260'ish kW)- but once depleted the on-site power feed is not able to provide 260 kW, so you may only get 20-80 kW charge rate…once the onsite batteries are depleted you can not under any circumstance get full charge rate. Once the batteries charge overnight (when power is cheaper) you can get full rate again the next day, until they are empty. An employee at this dealership explained to me they can handle 2-4 Taycan's a day - and then thay can no longer charge at full rate…nothing to do with the car, limitations of the equipment/capacities at the charging site.

unless you control for all the variables you simple can NOT diagnose why you are getting the charge rate you are getting for any particular charge session - and both the station and the vehicle DO NOT provide enough information for a conclusive diagnosis

so when it comes to fast charging you get what you get - and there is no way to tell why you are getting the charge rate you are getting.

there are so many conditions and variables required to align to achieve/experience the optimal charging rate (site equipment, time of day, ambient temperature, battery temp, battery SOC, recent charging session, state of the power-grid feeding the site, billing practices, other EV's charging at the same time, etc) that you simple can not conclude anything from a single session.

Thank you Daveo4ev . At least I wont waste my energy to figure it out.

Figuratively and literally (since driving to the dealership would in fact use energy from the Taycan battery)
