Help - PiP seemingly dead

No, the logic for this happens at the car end. You need to push down on the release button to "reset" the charge state.
At least that's how it's supposed to work I think. Should be easy enough to test.

 

they've designed the system so you can't leave the li-on batteries fully charged and continually topped up for long periods of time by mistake.

 

Sounds like a good idea.

 

Until you come home after a couple weeks and your PiP is stuck in the garage or dead at the airport.

ToyotaCare should develop a remedy for these types of issues.

 

That would be awesome logic if all that was being charged were lithium batteries. If the charger also charges the 12V battery, then that was a poor choice over letting the charge manager decide whether the batteries get topped off and independently monitoring and charging the 12V battery.

 

Maybe it would be a good idea to have one of those battery disconnect switches to use when leaving the car sitting for an extended period. BTW, does increasing the amp hours add to how long a battery can sit unused?
In another thread, Lensovet mentioned that his mother has never charged her PiP in several months of ownership. So that indicates that the ICE must charge the 12volt, so why do we also need the EVSE to charge it?
As for getting a new car with a bad battery, I experienced that with my Lexus. We bought it in late December, and by February it was dead, despite having been driven once a week or so, admittedly mostly for short trips. Dealership replaced it after finding bad cells or whatever.

 

well, the ICE also recharges the traction battery, so we do we charge that?

 

In addition to while charging, I believe that the 12v battery is also charged from the traction battery any time the car is in READY mode, in which case if the traction battery charge gets too low, then the ICE will kick in. This is how it works when you hook a 12vdc->120vac inverter onto the 12v battery for backup power.

 

I did put a switch inline with the neg 12 V, use it for rebooting also.

 

When you got the PiP started was there a CEL and any diagnostics codes to indicate the 12V battery was getting drained?

 

I misspoke when I said the ICE charges the 12v, because of course it does it through the traction battery, right? IOW, there is no conventional alternator to charge the auxilliary battery.

 

They do, you use your phone to connect to Entune and tell it to start charging a couple hours before you need it.

 

while "Entune" is slowly draining the 12 v

 

Suggestion: if you leave your PIP for an extended length of time, connect this to the battery and place in the front seat where the sun shines in.

This is only available on the advance model.

 

Edit: Screwed up somehow; tried to quote Kitty's post and wound up making it look like the whole thing was his. My apologies.

 

that's why I said connect to the battery, and the cord can be extended to reach from the front seat to the cargo area where the battery is located

I noticed they also have a permanent hook up for the battery that accepts the lighter-type plug. But I've always heard that you shouldn't hook the negative connector directly to the battery the way they show in the picture. Is that no longer a concern with modern batteries? I think I heard it was because a battery could explode. Maybe this solar thing doesn't generate enough all at once to cause a problem?

 

Don't know the answer to that, I bought the solar charger to power my cell phone if the power should go out. I also got this to connect 12 volts to 5 volts
