Prius Plug-in 2012-15 :: No Complete Charge - Battery Not Working?
Sep 24, 2012
On my last few charge cycles, the PiP's battery has not been charging completely. Even when I get the "charge complete" message, the top part of the battery indicator remains unfilled and I'm only getting 14.1 estimated range.
For comparison, last month I used to get 15.2 to 15.6 of estimated EV, when the battery icon filled completely after each charge. I always use the charge timer to set charging to finish 10-20 minutes before I need to drive the car.
My M-F routine:
- car finishes charging at 8:30 (13.8-14.1 estimated EV)
- I drive 8 miles to work at 8:20-8:30 (5-7 estimated EV remain, depending on traffic)
- I set charge timer to finish at 6:30 (13.8-14.1 estimated EV)
- I drive 8 miles to home at 6:30-6:45 (5-7 estimated EV remain, depending on traffic)
My weekend routine is obviously different, more driving, more charing, and not using the charge timer. Could it be because i'm not using all the EV so the battery is being lazy and not feeling like charging more than I need? Are there any known side effects of mixing 110V and 220V charging?

Happened to go down to garage to get something from pip about 3 hours after charge was complete and noticed loud hum coming from right rear wheel well area.
We had not had any lightning storms, electrical interruptions or anything odd; house is on whole house surge protection, and 240v evse has been working fine.
Hum disappeared when car was booted up in ev for a moment and then turned off. Hasn't come back on in an hour.

I have noticed this, and thought it strange. I don’t see the charging arrows in the display.

I had been running on EV then parked in the cold to wait for the wife. Turning on the heater started the ICE (of course). It charged the battery about 0.6% then stopped charging, ICE still running. So I switched to HV and it restarted charging about 0.3% and then stopped charging. So I switched back to EV for a few seconds than back to HV and the charging resumed another 0.3%. Once the coolant temperature reaches 130 degrees the ICE stops. Nice heat until the coolant gets down to 118 degrees and the ICE starts again. Back in EV and the battery is charging and the HV/EV switching continues to add more charge. Until time to leave I picked up about 5% SOC, kept warm. Not good for mpg but 5% SOC is nice.

I don't plug my PiP in often due to the cost of electricity here, but what I have noticed that when it has a full charge, around 13Miles, it will quickly drop down to 7-8, even when not using EV. Meaning, I start up car, turn off EV and the motor gets warm. Engine shuts off and I drive normally using the ICE. Over the course of a few miles, I'd say about 10, that EV range slowly drops down to 7-8 and then maintains itself around there. Pretty much the whole time I would have been using the ICE to maintain ~70MPH on the highway, not climbing, just flat.

After my 25k service it seems the timer scheduler when the square button is pressed/held flashes at 7am. When i press the H button the hour advances to 12am then closes. I want to start the charge at 12am and finish at 5AM. The timer windows closes when i move the finish hour to 12am and then my regular clock hour changes. It used to be when i pressed/held the timer button the start time would show at 12 am and after setting it would go to the finish hour.

Does the A/C and heater run only with Ice? Or is it able to run on EV alone?

Hymotion battery pack is dead. Won't charge beyond .8 kw max. Doesn't charge enough to offset the cost of the added weight of the pack.
How can I get this "boat anchor" removed.

Why won't the iPad charge when plugged into the USB port in the center console ? My iPhone charges and auto plays but the iPad will only auto play.

If the following variables are true:
-Extremely cold day out (highs in the single digits)
-Will be hauling around people that like a very warm car
-Will be in a lot of stops and go traffic
Is the best practice to charge only to about 2/3 or 3/4 of the way full (according to the battery graphic on the HSI)? My thinking is the ICE will be running a lot while stopped at stop lights and waiting in traffic. And I might as well have somewhere for all that extra energy to go. I know we are kind of splitting hairs here, but I wanted to think about this situation before it actually came up.

Really starting to get a little frustrated and would love input.....
Owned our PIP for almost a month now. First week, fully charged EV miles were showing around 13.7. 2nd Week, around 12.2, 3rd week, 10.5 and now this week it's gone from 9.6 to 9.1???

I just purchased a '12 PIP advanced a couple days ago. Love it so far, but I'm confused about why it keeps on switching out of EV mode before the charge is used up. My commute is 6 miles, so I assumed that I would be able to get to my office with no problem, using only electric. Without accelerating quickly or going above 62 mph, the car still switches into hybrid mode numerous times, for no apparent reason, resulting in an average of about 90 mpg by the time I get to work, still with a lot of juice left in the battery.
Why this is happening? My dreams of going for months without filling up with gas are starting to fade away.

I know I am unusual but most days I drive about 3-4 miles. I can get 2-3 days out of a charge. Should I plug in every night or just when needed? Does it use more kWh to plug in every day?

Edit (3/2/13): Problem identified. The timer was incorrectly and inadvertently set, so charging wouldn't start. See this post below.
Three times in the past two weeks, my PiP has refused to take a charge. It happened twice on Chargepoint chargers. The second time, I plugged in and the charger displayed "Vehicle refused charge" or something similar. Tried 10 times with the same result. Then it charged fine at home, and on 240v the next day.
This morning, it won't charge at home on 110. Plug in, the brick clicks, it draws about 200 ma for a couple of seconds, and then zero. Totally repeatable.
No fault codes on Torque. The dealer had it earlier this week and couldn't make it happen or see any fault codes either. The first time it happened the charging cable was off the ground, so I suspected a bent pin, but they all look fine.

I live in NJ and in summer I am getting a full charge of 8.1 miles. In winter i used to get almost 11 miles. I thought in summer the charge will be even more?.

I received a message similar to this when I started my car up this morning. I am paraphrasing because I don't remember the exact wording. I had set the timer to charge from 4am-7am and entered my car at 7am to this message and 0 charge. Did I just plug it in correctly or what does this mean? I've never had an issue until today.

When stuck in traffic jams, and my 2004 Prius shows 2 bars on the HV battery charge, it attempts to start the engine to maintain the charge on the HV battery. What was happening was the engine would attempt to start and then it would immediately die. It would keep repeating this process, over and over again, and would not charge the HV battery. Once I started driving out of the traffic jam, the engine ran fine and it charged up the HV battery while I was moving down the road. I decided to clean the throttle body. My charging problem did change due to me cleaning the throttle body. Instead of starting and immediately dying, over and over again, the engine no longer dies.
It now revs up, and slows back down to idle over and over again when sitting still with 2 bars of charge. The display does not show any charging going on during this revving up and slowing down episode. I need some more hints as to what to check out. I am studying electrical diagrams of the vehicle, but I need a synopsis of which system starts the engine for HV charging, and which system keeps the engine revving at the same RPMs during charging while not in motion. The throttle body cleaning made my 257 K mile Prius run like a scared deer again. I just need to get her charging while sitting still again. 12 volt charging system is in the 14+ volt range and 12 volt battery with no load is around 12.2 volts.

PIP does not charge the plug in battery while driving....

Wondering if there is another factor involved here...such as the wrong gauge. I'm routinely seeing battery temps in the mid to low 90s even when it is pretty warm weather and I am in EV. Is this possible? On my old Gen3 even when I use the battery just a little bit on warm days it would go over 110. Does the lithium chemistry just keep it that much cooler? Or does the cooling system keep it that much cooler? Or both? What are other people seeing for battery temps?

just came home and while inching into the garage on EV, noticed that the battery fan was on.
I have not noticed this before, except for when the battery is actually charging.

My wife plugged in to the EV charging station at work for the first time today. She was supposed to receive an email when the charge finished but wasn't notified because there was a still a trickle charge being registered by the EV station even though the battery was full.
