I've left cars parked for over two months without issues, two weeks shouldn't be a problem especially if the battery is not over 3-4 years old.I would have thought that leaving it for 2 weeks at 80% would be fine for the main battery without being plugged in, but as for the 12v, that's in the lap of the gods by all accounts.
Good point about the tyres, never thought about this!Any car should be fine for a month with a health 12V. Obviously the scare with the polestar is the 12V issues ... but if you have had your car for several months them I'm sure any 12V issues would have been raised by now.
As for the main battery ... the worst phantom lose was around 1% per week. So any state of battery between 40-80% would be fine.
Just remember you'll have flat tyres when you get back, so drive gently until the tyres go back into shape ... no 0-100mph acceleration tests after picking the car up ;-)
Well my 12V battery problem happened months after I took delivery in early September.Any car should be fine for a month with a health 12V. Obviously the scare with the polestar is the 12V issues ... but if you have had your car for several months them I'm sure any 12V issues would have been raised by now.
Except that the battery in the ICE car the batter will go dead inside of 1 month. Happens with two of my ICE. I have heard related stories, all blame people blame it on the alarm systems.An ICE car can be left for months and still run if the 12V is healthy.
An EV's 12V is doing to the same job and as any ICE 12V. Alarm, Central Locking, Keyless Entry, etc...
I have left my car in the garage, not plugged in for a two week period unused. No issues at all. The main battery losing maybe 1%This is what I heard back from Polestar support today:
I just asked one of our internal engineers and it was stated that the vehicle is not recommended to sit for longer than approximately 30 days unplugged from a wall-box/AC charger. After 30 days, the 12V battery may begin to see some voltage loss, leaving the vehicle unable to start. The high voltage battery for the vehicle should not see any loss from extended periods of storage however. If you have the option to keep it connected to an AC charger while in storage, then your vehicle can remain stored for longer periods of time.
I was just wondering if there is anything I could manually turn off to increase that longevity. I don't imagine leaving it for more than 2 weeks ever.
Every few weeks, I push the vehicle a foot or two backwaed or forwards. If its a nice day I might take it for a drive, (so long as it's taxed and insured)For anything longer than a week or two, you really should use a battery tender on the 12v. It's the same with ICE vehicles, except you sometimes have to drain the gas tank and run the engine till the fuel system is dry if it's going to be a really long time.
Storing on jack stands is another plus so you don't flat spot the tires.
Theoretically you can leave an EV for months, maybe well over a year, before you deplete the HV battery enough to where it can't keep the 12V topped up. But 12V charging issues are a thing with EVs, so if you're leaving the car unattended for weeks at a time a tender is additional peace of mind.Honestly, EVs shouldn't need any kind of battery tender and should be fine to leave indefinitely - the top-up charging from the high voltage pack is doing exactly what a trickle charger would do, only with much more precision and control. Just more misinformation from people guessing, sadly.
Fair point. I wasn't sure if it's something that could materialize while the car is unattended.Hmm, I'm not so sure. As I understand it (and have experienced it multiple times on the Kona), either the car shuts down properly or it doesn't. If it shuts down, it should be fine indefinitely, topping up the 12V when necessary. If it doesn't, then it'll be flat the next morning. Also, a tender may not be enough to deliver the 2 or more Amps that the non-shutdown car takes.
