Porsche Navigation vs ABRP vs Apple Maps EV Routing -- Pros and Cons

[whitex]

You cannot manually. It must be done through the nav function as it approaches a charging station that is a programmed stop in the nav.

All that said, there is a "sort of" workaround you can do. If you set a departure timer, the car will 1) climatize the cabin, 2) heat or cool the seats, 3) heat the battery a little... not all the way to optimal battery charging temp, but enough for driving.

Obviously, that's not very practical if your intended use case is preconditioning the battery for a travel stop, because the car needs to be off before a timer would trigger precondition the car for use. That and if you're driving the car already, the battery will already be subject to the driving temperature.

However, if your use case is "I'm leaving my house at 7am and heading to the EA charger one block away", setting a timer will at least partially pre-heat the battery more than if you got into a cold car.

I did talk with a Porsche N.A. tech team member on the phone last month after asking this very question because the Porsche / Apple EV Routing integration didn't seem to support preconditioning, and he told me they were evaluating other ways in which the Apple Maps and car could communicate, and that was one area they wanted to look at next. But I wouldn't hold my breath for that.

Another "sort of" workaround is to drive in "Sport Plus", which ups the battery target temperature. Unfortunately I have not paid attention to what temperature the car preheats the battery to charge, anyone out there note it down? We could compare against the Sport Plus target temp zone (which I will need to dig up, but I know I have it somewhere).

It is a little frustrating that Apple Maps won’t connect to the HUD which I really like and very good on Taycan, it’s crisp adjustable and configurable.

I agree. I think so far, the best I can come up with to solve all of these issues is the following:
1) Enter destination into car nav and display directions on HUD
2) Disconnect the phone from CarPlay so that you can use navigation apps on the phone without disabling the car's nav (and associated HUD display)
3) Do one of the following so that you can use the better routing of either of the following apps:
- Apple Maps: Connect to CarPlay long enough for Apple Maps to obtain the inital battery SoC, then disconnect it. Now Apple Maps starts with the correct SoC and can route you correctly to your destination or first charger stop if a charge is required.
- ABRP: Use a dongle to live-stream the SoC throughout the drive and use ABRP to route you to destination or first charger stop if required.

Even if the app-of-choice on your phone initially routes differently than in-car nav, they should eventually converge if EA chargers are used by the app. The battery should therefore pre-condition and you can use the HUD to see the route. You can also use Innodrive more effectively if equipped. Innodrive will, for example, know you are turning right at a certain intersection and will slow down as you approach your turn. If the car nav doesn't know your destination, Innodrive still does it's thing adjusting speed for the radius of turns on the road you're driving, but it won't know to slow down for planned turns along your route.

In the event the routes are different and your app-of-choice is routing you to an EA charger, you can program the EA charger into the car nav as your destination. This would also allow you to pre-condition the battery and use the HUD without waiting for the car nav to converge on the route the app is using. Programming in each charge destination one-by-one basically eliminates any issues with the car nav and app initially planning different routes.

The only way this doesn't work is if your app-of-choice selects a charger that Porsche nav doesn't know exists. In that case, the car won't know there is a charger even if you program that charger as the destination. You can still program the charger as a destination, but it just won't know to pre-condition the battery. That will still allow you to use the app-of-your-choice to route and monitor your projected SoC AND use the HUD and utilize all the benefits of Inno-drive (which would then know to slow down for a turn for example).

All of this preparation takes time, though, so only makes sense on a long journey.

Based on posts from others, the battery pre-conditioning temp targets about 105 degrees F, or about 40 C. So gets pretty hot. I don't know if this varies based on factors like the outdoor temperature. I can't image the battery tries to heat that much during winter for example.

Ok, I dug up something I found a while back, temperature ranges for different modes.

From this, it seems driving in sport will give you a similar profile as charging, Sport Plus should get the battery at the upper half of the charging range - so starting charging nice and toasty.
