Charging at home with low battery temperature

[Mark..]

Anybody had/have this issue?

I charge my car over night on low rate electricity. When the weather is cold my battery temperature can drop as parked outside. If the battery temp drops to about 4C or below the charging fails with a ‘charging error’. I would expect the car to heat the battery/precondition it and then charge it but it always fails. If the battery temp is above 4C it charges fine as intended.

Is this normal or a fault with the charging pre conditioning system?

What charging power did you have available when this happened? Maybe the power was insufficient once the PTC heater started up?

I have had my car charging at night temperatures down to -20 C with 11 kW without problems in Norway lately.

It’s 7.2kW. I have seen on the app that it starts charging at low power (1.2kW) and then jumped to higher powers (up to 6.8kW) then down again goes in and out of ‘initialising’ and after about 20min fails with an error.

it fails consistently if the battery temperature is low and always fine if the battery temp is higher. PRC is saying it’s normal and when I mentioned about how they charge in Norway was told the cars are different which I believe to be rubbish.

Well you can tell them that my car has been purchased and delivered in South of France and had no problems in Norway! I do not think the French delivered Taycan is different form yours ( apart from steering wheel position ?‍)

I have not heard anybody in U.S. or Canada that has mentioned any such problem either?

Definitely not normal. We don’t experience that in cold climate here and charging at -20C is just fine

Not had that issue. Which EVSE are you using?

Sounds like a really bad argument. Your car should perform exactly as all other Taycans. Do you have the ability to test with a 11kW charger? To see if available power makes a difference.

I'm pretty sure I have charged at something like 4kW in -10C without issues. The chargers at my workplace use load balancing and go pretty low during the first half of the day. I charged every work day through winter with no errors.

The Porsche mobile charger connected to mains via commando socket. Hence 7.2kW.

Note the issue is with battery temp not ambient. I can charge if ambient below zero so long as the battery is above 4C.

In my case the battery has been below freezing when starting the charge.

Ok so no obvious reason why it wouldn't charge to my mind - both car and evse are within normal operating parameters.

Worth consulting your dealership.

I have a call with the specialist Taycan technician tomorrow who I’m told by the dealership service advisor is going to explain to me why this is ‘normal’. Can’t wait to hear what they say.

I had the discussion with the technician. He believes my issue is due to the car and charger being at different ambient temperatures - car is outside garage and charger is inside garage. He wants me to put the whole charger outside and see if I still have the issue. I will do this but highly unlikely this is the issue. After all many chargers are wired inside and cable is fed to the outside and also, to my knowledge, the only comms between the charger and car is the car asking for specific power. We have a few cold days coming up so let’s see….

Imagine that, you can only drive your £100k+ car to places that are the same temperature as the battery! Must have missed that in the small print.

Sounds like utter c*ck being spoken by someone who knows it will be a nightmare trying to replicate it and find the fault. Rather than p*ssing around moving your set up, suggest they lend you a similar car for a night and see if that does it too. They all have loads of them on the forecourt at moment it seems, so shouldn't be a problem!
Ditto if you're using the porsche EVSE, get them to lend you a different one.

Side comment: When i had home charging errors it turned out to be a problem with low voltage coming into the house. Needed fixing by the power company. Probably unrelated and i can't see temperature effecting your home voltage, but thought worth mentioning.
