Just wondering if you going on a trip do you leave you car on the charger. I have found mixed results? Your thoughts.

Can't really see the need to put trickle charger on 12v battery, If you have the setting set right on car the main motion battery will keep topping 12v battery up if required! Only had EV for a week but previous car was Ioniq PHEV, and would regularly get message when first using car after it had been stood for few days saying 12v had been topped up!Suggest leaving your 12 volt battery on a trickle charger. As you would do for any other vehicle. PHEVs often have 12 volt battery issues so a trickle charge once a month anyway is a good thing. As suggested above, the 12 volt system has a role in charging the traction battery so leaving that plugged in could drain your 12 volt battery.
Which means you have not been reading posts about failed batteries on this and many other EV forums. Doesn't affect everyone, but those who trickle charge their low capacity 12 volt lead acid battery once a month appear to be guaranteed long lasting batteries.Can't really see the need to put trickle charger on 12v battery,
Sorry to say I have read links about failed batteries, nothing say's why they failed, my PHEV is 2.5 years and 32,000 miles no problem with 12v battery, although did get notice that it had been charged by motion battery quite regularly, new EV is 10 days old and 180 miles and went out this morning to see blue dashboard light flashing(means 12v battery being topped up)!Which means you have not been reading posts about failed batteries on this and many other EV forums.

Dialogs about charging your 12 volt battery mostly means you have a lot of drain on them when the car is off. Not a good thing - they are notifying you about that so you can be warned.
In fact, I do have a motorcycle and practice what I preach, buying a trickle charger the first winter. It is now 7 years old without a hint of battery degradation. Of course, with such a small battery, failure will probably come fast when it does.I do agree with a small battery maintenance device. I can get years out of my motorcycle battery using one. Instead of a single season. I’m sure the same could be said about our 12v.
Because they don't have alternators that are constantly charging the 12 volt battery, an automotive system with 60 years of proven worth. Instead they have an intermittent system triggered by low voltage to charge the 12 volt battery from the traction battery by a DC to DC inverter. This DC inverter is controlled by the 12 volt system which means any failure results in a dead 12 volt battery with no ability to tell the inverter to charge it. Multiple instances of low voltage in a lead acid battery can shorten its lifespan dramatically.Sorry to say I have read links about failed batteries, nothing say's why they failed
Like motorcycle batteries, that small 12 volt battery in the PHEV and BEV is surprisingly expensive. And it is not covered under the drivetrain warranty. So preserving it makes a lot of sense.
There is a 2 year warranty on the 12v battery here in Australia from when you purchase the vehicle.
