My mum's 2019 Toyota Yaris has to have its engine run every few days or the battery dies from just sitting on the driveway. It could be a faulty car battery but considering this car isn't even that old and has barely driven 30k miles, it's not doing so great. I discovered yesterday that my EV charges better after I've driven it around and the battery's warmed up a bit. The car goes a bit haywire when you cold start so it seems like it needs some prep time before a drive.
Yes it does. You car (almost all EVs) slowly precondition the battery while driving. Many newer cars optimize the battery temperature when you add a charger to your navigation to have the optimal temperature once you reach it. If you know you need to rapid charge and the drive is short, it's usually a good idea to add it to your navigation as the car will then maximize the heating/cooling before you get there, whereas with normal driving it would do this slowly to minimize drain.
I had to rapid charge with a frozen battery once. Not a fun experience.
... If another one of your vehicles died constantly... What would you do...
