Turbo EV sitting for 3 weeks

[maddie288]

I have a 2025 Turbo and will be away for three weeks. Any suggestions or just leaving it locked it will be ok? My plan was to charge it to 85% before I leave.

Shouldn't be an issue, but I always do 50%.

Yes, 50% state of charge. This percentage places the battery in its chemical "sweet spot" to minimise stress and prevent degradation during inactivity.

100% agree with others. Do not do 85%. 50% is what you need.

Thanks folks great advice!

Also keep the keys out of range and don't constantly check on the status of the car using the app.

If your car is one of the several with 1% SoC loss per day, SoC will be around 30% after 3 weeks, so ok.

If I remember well, owners manual writes to set the battery at 50% and plug it in

I returned week ago from a 10 week trip. I left the car at 61% and hooked up a trickle charger to the 12v battery. This is in southern Arizona, garage temps averaged in high 90s at peak daily, 70's at night.
On return, the battery was at 60% (I checked the app several times over the trip to monitor this), car runs fine, no tire issues, just the usual, occasional, fleeting random electronics warnings that I always get and ignore.
Last night I tried to charge at home for the first time since returning and had several 'failure to charge messages' which I reset and re-initiated the charge... gave up after 5 or 6 tries. This morning it is now charging fine... so far.

There is a OTA update for the high voltage battery charging when using Level 2 AC EVSE. It's also in the WTA6 campaign software update that the dealer can perform -- that update also includes a bunch of other fixes.
