Extra miles from battery

i hate to say it, but it sounds like something is wrong with your car.
are you only getting around 10 miles in slow back road ev? if so, maybe something is preventing full use of the battery.

 

It looks like your car was smart enough to shut itself off before the 12V got too low. And batteries will bounce back up a little bit after the load is removed. Yours apparently had enough juice left to fire up the computer and close the hybrid battery power relay.

Had you just left it in READY mode, you could have sat there for days with a full tank of gas. The traction battery would have supplied the 12V battery and the engine would have charged the traction battery as needed.

I would keep an eye on that 12V battery to make sure it wasn't damaged by being run down so far.

As for the EV range anomaly, I have no idea!

 

Consider also another possibility, that this may be a curse, not a benefit.

For battery life expectancy reasons, the car normally does not allow you to use the entire battery capacity, but restricts the normal cycling to the center portion of its range. If the reboot erased some information or confused the car about its charge level, the reboot might have allowed it to dip into the bottom levels that are normally set off limits. Good in the short term if you need that portion in an emergency, but bad in the long term for battery life.

If this is what happened,hopefully it won't take long for the car to get back on track and again cordon off that portion of the battery.

 

While you are looking for that fuse, bear in mind that the Plug-in tries to maintain its state-of-charge between 20% and 80%. So, a "full" charge always stops at 80% and the engine starts at 20%. (Verified with a ScanGuage II in the OBD port).

 

how does this explain your phenomenon?

 

well, with all the 12v disconnects and new batteries and such, no one has ever reported this happening before. can you try to replicate it?

 

My 2012 PIP sat for more than 2 weeks and the 12 volt battery was dead after jumping and recharging the EV battery fully next day it read 14 miles, the longest it's read since purchase.

 

when 12v is disconnected, ev estimate goes back to factory default. the real issue here is, are you getting any more actual miles?

 

Why did the battery die after sitting 2 weeks? Rarely using ICE is my explanation, yours? Also it seems 12 volt battery replacement is $400-600 as Toyota decided to use a battery in the PIP that no one carries and is unusual?

 

no, it was probably drained at some point previously. after that, they lose all their gusto. the inverter charges the battery when you drive ev, otherwise, there would be a lot of pip 12v problems. i have 32,000 ev miles and 18,000 hv miles. i drive only ev for weeks at a time, except for the mandatory 124 mile engine exercise.

i leave my pip for 5 weeks every winter, still measure 12 .6 volts.

you can pick up an aftermarket battery for around $150. or a toyota for $200. there are 4 or 5 aftermarket batteries now. installation is easy, if you don't want to, a local mech shouldn't charge more than $75.

 

Could you provide a link to the online source for a battery, and is the battery the same for all 2012 PIP 's,? Thank you for your help

 

yes, the same battery for all gen 3 including pip. optima is available on line. you can get a duracell at batteries plus bulbs stores, and there are a couple others available at auto parts stores.

 

ICE time doesn't matter to the 12V. It is charging all the time that the car is Ready, which includes all EV time.

My Liftback is the same age as your PiP (I bought it three days before you joined here), and its 12V is showing signs that it is nearing the end of its life. Knowing that, I shut SKS off for a 6 week trip last summer, the 90F temperatures on return probably helped it start. Right now, snowing on dad's farm, it hasn't been moved in ten days and the voltage is low. It will get a lot of on-road charging time tomorrow.

 

I have 27000 miles you?

 

Mine has 64k miles, so it has spent vastly more time in 'Ready' mode charging than has yours. Waking it up in non-Ready mode a moment ago to check, my ScanGauge is showing 11.3V. Good thing I brought along a portable jump pack, in case it doesn't want to start tomorrow.

 

Depends on how fast you're going. The slower you go, the more EV actual miles you get
