ROUTE MONITOR - NAVIGATION

[GasStation]

The route monitor shows a battery remaining of 56% at destination but my actual battery level is 42%.

What exactly is the route monitor battery % reflecting?

Anyone with road trip experience and knowledge appreciated.

I have the same problem with my car. My dealer reported it to Porsche Netherlands. A ticket has been created so that the problem is acknowledged and investigated.

The initial explanation is that the car is not interpreting the battery correctly. Therefore, the car will be picked up, charged to 100%, and then discharged in a controlled manner. This will likely be done a few times, as they have reserved just under a week to resolve the issue.
I cannot report anything more yet, as the appointment is not scheduled for another month.

I was having a similar problem immediately after the WSJ0 update. I would arrive at destinations (supposedly) with more charge than before I left.

The problem disappeared after I charged to 100% (when I usually charge to 80%) and received a newer version of the PCM charging app with new features. I also have the most up-to-date version of the iPhone app after first deleting the app from all my devices.

You can also try the standard lock and walk. If all your keys are well separated from your car for 45 minutes or so (or kept in a Faraday box) that should cause the car to reset. Finally there is the PCM reset if other remedies don't work...

Also be aware that the range estimate for the battery SoC is based on your recent consumption, whereas the navigation system will consider whether the route to your selected destination includes elevation changes, speed changes or weather conditions that will significantly affect consumption. Consequently, the two numbers will rarely agree.

I have a similar problem route planner estimates battery a destination that’s more than the actual battery current charge. Only happens with me as user, if I log out and use guest the planner battery estimate is back to being accurate/ slightly pessimistic. If I need to charge on-route I log-in as guest and live with having to set the radio and plan on the PCM. I do have a ticket with Porsche GB looking into it.

I had this problem too last August initially but it went away after a couple of weeks. It's reoccurred a couple of times since though.

Can't be certain but I think this can be resolved at least temporarily by running the car down to a low state of charge (ie 3% or lower), leaving it overnight, running it down to 3% or less again if the SoC has gone up and then charging to 100%, leaving it again overnight and finally topping up again to 100% if it has gone down overnight. A bit long winded but it possibly cures this and definitely fixes issues with improbably range remaining compared to SoC. For example mine was reporting 0 miles range at 10% charge a couple of months ago and this process fixed it.

As noted by another poster, logging into the car as a guest user may fix the problem too. It didn't for me though.

I had this issue. It was resolved by the dealer installing several small updates including a battery management one. The issue occurred after the major update but not immediately. Been fine ever since The BM update.

Hi yes I have the same problem with my car
