Taycan pre-heating

[Sidicks]

I'm very aware about the importance of scheduling charging stops on the Porsche Nav so that the battery can be preconditioned ready to accept maximum charge when you arrive.

However, I've not really bothered too much with planning to pre-heat the battery prior to my normal journey, which therefore results in incredibly high consumption in the first few miles/minutes and clearly hits the overall predicted range.

Now that the weather is getting colder, I'm thinking that it is probably even more important to do so, albeit that the car is kept in a garage so is protected from the worst of the weather.

So a few questions:
Timer:
- Clearly I need to remember to plug the car in every night in order to use the pre-condition feature!
- I know that I can set a profile on the Porsche App to prepare the car for a drive at a particular time - is this primarily designed to ensure a minimum level of charge or can this be used purely to pre-heat the battery without necessarily seeking to add charge?
- When I'm working in London, I tend to leave the house at broadly the same time each day. However, I typically only go into the office 3 days a week and which days cary from week to week.
- Should I set up a Timer that operates on every day of the week and then manually turn off/on the timer for the next day to fit in with my schedule or is there a better solution?
- If I know I will need to drive the car in the next hour (say) is there an easy way of pre-conditioning the battery for the journey, or is setting up a new timer profile the only way?

Pre-heat/cool:
- I assume the 'Pre-cool / heat' part of the app is entirely separate and can't be programmed to operate in tandem with the battery conditioning, it's just a case of manually clicking the button to pre-heat/cool the car, as needed?
- Is the heated steering wheel linked to the above?

I know that after 4000 miles and 4 months of ownership I really should know how this works!!

Some bright spark on here worked out you can use voice command in the car to tell it to heat the battery up. Also means you can head for non-porsche chargers too.

I haven't tried yet, but as a 99.99% waze user i find the porsche satnav unfathomable when i want to find and set a charger as my destination (rather than let its 'smart' functionality decide where i should stop). The charger search function (when i use it anyway) seems to sort by provider rather than location. Example, i seem to have to search for all osprey chargers, then find one near my destination, rather than putting in a motorway service station and it telling me what's available.
Probably me being a luddite.

This doesn't work. Or at least it never worked when I tried many combinations of words on my car. The few times it said okay, it turned up the heat in the car. I'm 99% sure there is no way to tell the car to pre-heat the battery through the voice control system.

i haven't tried and i can't remember the magic phrase, so dunno!!

I tried the "magic phrase" verbatim (can't recall what the thread specified anymore) and then many other variants. IIRC the first phrase turned up the cabin heat in the car by a few degrees. It was the equivalent of saying "Hey Porsche, I'm cold".

in that case i'll have to stick to putting it in sport+ mode for a few extra degrees!

Here is the earlier post that said you could preheat the battery for DC charging with a voice command. That post is incorrect and has caused alot of confusion. But yes, Porsche should make this feature available because unlike Tesla, where preconditioning works well and SCs are reliable, much of the time in the USA the info on a DC charger is wrong (availability, KW, etc. see attached images taken at the same time, and yes they are all plugged in and charging.). Often I know exactly which charger I'm headed for from another app and I don't want to go through the steps to hack the Porsche Nav to start preconditioning the battery and have to give up Waze. The other reason to preheat the battery, but to a lesser extent, is before driving in cold weather. I'm just starting my first winter, so I haven't done all the experiments yet, but it certainly seems that hitting precondition on your phone 60 minutes before you leave should get that battery warmed up on grid power before you drive.

Preheat / precool is the only control you have regardless of purpose. There is no mutual exclusivity - cabin heating Vs preheat / condition the battery.

Home charging on AC doesn't generate a lot of heat (or conditioning) due to the low kW available.

Daily timer and profile for a departure time with a cabin temp of say 23C might get your battery up to 20C.

 

[Murph7355]

With an ambient of 5degC and a cabin temp of 22degC, my battery was 14degC at take off time today, plugged into a 32A single phase home charge (so 7kW or thereabouts).

Tomorrow morning will try and remember to check it without any preheat.

Profile is just for minimum charge.

On the timers, you could set up 5 timers, Mon, Tues, Weds etc. And then switch combos of them on/off to suit that week's pattern. But if your pattern is irregular there's no automatic way to trigger this.

The preheat button on the front page of the app is just the cabin, I think, and not on a timer.

You could, I think, set the desired charge level to the current battery charge %age (or lower?) on a timer and have the cabin preheat set. I think that should serve just to heat the cabin on a timer.

Why is it incorrect?
I say ‘Hey Porsche, pre-heat the battery’, it responds ‘the battery will be warm soon’. I can’t see how that is ambiguous? What I can’t explain is why some people can’t replicate it. I did it on a MY23 4S ST loaner. I haven’t yet tried it on my MY24 GTS ST.

 

[Sidicks]

Well, as I’m asking stupid question (and am too lazy to RTFM)…

On the middle touch screen there is a ‘direct charging‘ option and a ‘pre-heat/cool’ option. Am I correct in:
a) using the first of these to override any pre-set modes and just charge the car as fast as possible
b) using the second of these to get the battery ready for charging if I’m heading towards a charger that’s not programmed into the Sat Nav?

It's incorrect because a bunch of us tried to replicate it with 0% success rate. Even if it did work for you on one car 100% of the time, it'd make it an anomaly.

b) using the second of these to get the battery ready for charging if I’m heading towards a charger that’s not programmed into the Sat Nav?

a) yes (AC only)
b) no (heh, this, too, is "AC only" ?)

It may be that this answer is less useful than TFM, I make no guarantees..

We'll,

A) DC button overrides all timers and profiles for AC charging and will charge immediately until you stop it.

B) Preheat button is for cabin temp and depending on conditions will fire up A/C using the last setting, switch on the heated seats, wheel and rear demister.

Only direct way to preheat / condition the battery is to use NAV for a DC EVSE >= 50kW.

That's all.

Well I woke up today to find the car at 57% charge for my 06:55 departure, despite having set an 85% target.

Despite being connected to a 22kw charger, the car was only pulling c. 4kw when I went to bed last night, but I had assumed it would increase the rate as required to get to the target.

I will try again tomorrow.

 

[Murph7355]

Had a look at mine this morning... Not plugged in overnight.

Ambient 12.5degC, battery temp 12degC.

So on one anecdotal test, AC charging on a departure time does seem to heat the battery (day before ambient 5degC, battery temp 14degC).

Will try and remember to check it a few more times.
