The only thing that charges the traction battery is the motor/generators powered by ICE or regen braking. Letting the 12V battery charge for a few minutes allows the traction battery to determine its safe to reconnect itself to the system without concern that the 12V system will draw it down past it's safe level. It's all about protecting the traction battery and why these batteries are suppose to last 15 yrs in the car when the identical type of battery used in a laptop is ruined after 2 yrs of use.
If the traction battery charge falls below it's safe range, it will not reconnect to the system and it's time for a tow to the dealer for diagnostics (something is wrong!) and a direct recharge.

Just to clarify, Toyota has never made a claim that the traction battery will last 15 years. Perhaps you mean 150K or 10 years, which is the CARB state warranty on emissions parts?

I'm talking probable usable life, not warranties or guarantees. I guess I should have said "why these batteries should be able to last 15 yrs". From what I've heard, older Prius batteries nearing the decade mark and still going strong with little signs of giving up soon...

Droid13, your statement does make sense.
May I ask where you got the information to assert this ? Or do you just put forward a hypothesis ?
I would like to be sure before I change my mind.

The hybridsynergydrive web site describes the DC/DC converter among lots of different resources. The ToyotaIguide site makes mention that once the traction battery is outside it's safe range, HSD won't start and see your dealer (again, among lots of different resources). There is a dedicated port on the traction battery for charging it should something go wrong, of course that's where the manual warns you that you'll electrocute yourself if you play with it.

I've read in a few articles that Toyotas goal is for the traction battery to last the life of the car - typically 15 years or 200K miles.

Toyota does make changes... (I hope)

My car is one week old. Going back to the subject of drained batteries if car is not put to "P". I cannot get the key out unless I press the Power button. When I press the power button the gears switch goes into "P" position. Overall it must mean that the "P" gear problem is effectively solved unless you leave your keys in the car...
