Prius (2004-09) :: Engine On But Battery Not Charging?
Jan 26, 2013
Recently we went on trip requiring a 3 hour ferry ride. Decided to keep it in READY to listen to the stereo and maintain a minimal level of heat. I noticed the engine kicking on and no arrows from or to anywhere. The HV battery gauge was mostly down to 2-3 bars but still no arrows. There were times that it kicked on and the arrows showed the batteries being charged too. Was the engine kicking on without charging just to maintain the engine coolant temp to provide heat for the cabin, or what?

I have got Prius 2004. I have got a problem. With MFD. It's showing the screen where it should show that the battery is charging but it's not showing the charging at all. Car is running fine and starts as normal. I have changed the 12V battery but it's still not showing the charging.

I have an 05 prius with 108k miles that I bought about 3 months ago. I had noticed some times during phase 1 warm up where prius is in park and ice is charging the battery there will be mildly violent jerking of the car.
I was messing around the other morning, after driving the car about 30 minutes then letting it sit for about an hour in 40 degree f weather. I readied the car and it started charging the battery. While still in park i pressed the gas pedal to see what would happen. The mfd showed no arrows which I assume is normal. But when I let off the gas pedal there was a abrupt jerking as the mfd showed power flowing from the ice to the battery again.
Experienced jerkiness while in phase 1? After phase 1 is complete I do not notice any more of this behavior.

First a little background on the car , it has 217,000 miles. The battery was just replaced with a used one. While taking it through the carwash, she put it in neutral and a minute or two later she got a warning that the battery was not charging and to put it in gear. Sounds like the battery is having issues to me. She has a 60-day warranty.

195k miles.... I have charged the battery, I have bought a new battery, I have Charged the new battery... All with no avail.. Slowly but surely one at a time the abs trac control and stability control lights come on and eventually the triangle of death... Meaning when I shut it off its not going to restart.. If i drive it sparingly it might take a week if i drive it all day then it takes one day... when fully charged there is no warning or sign that there is a battery issue or draining untill the voltage is starting to get low. I have an ultra gauge hooked up and shows 14.14 while driving, I am lost as to whats the issue. also no codes or pending codes... I have taken the new battery to auto zone and had a functional test done.. said checked good... signed befuddled

The MFD on my 2005 prius shows that every time the gas engine kicks in, it trys to charge the batt. even when it doesn't need to be charged. This has been happening for about 2 weeks, and not one time has the gas engine kicked in without showing the arrow going to the electric motor, even when the batt is completely full. I know it's not just a problem with the MFD because my MPG average has clearly gone down since this started.

I've been noticing that my battery is almost always fully charged or close to it. Then I noticed that when I 'should' be getting assist from the MG2 and not charging the battery, i'm not getting the assist I would assume I should be getting. Seems like most of the energy is getting put back into the battery instead of assisting the MG2
Notice how the arrow is going to the battery from the MG2 (ELECMOTR) and not vice versa. This is majority of the time. Getting less of this also. hince - MPGs are down also.

I've seen this a couple times but always made it home with the Red Triangle and VSC warning. A year ago, I blamed it on the OEM 12 volt battery and eventually replaced it with a Optima Yellow Top. No more problem until today. Day time driving with my Plug-in Supply 10k rechargeable conversion performing normally. City driving raining but normal Western WA conditions. Red Triangle and VSC warning. Other systems operating normal.
I knew, from previous experience that the Prius operating systems would continue to work only until I turned it off. I did turn off the Plug-in Supply controller to isolate that system and observed that the OEM traction battery was at a fairly high state of charge and the ICE was still providing the normal amount of assist to the traction battery through normal street and driving conditions.
I should have driven the 20 + miles to get home, even with the Red Triangle warning. I had done that in the past with the old OEM 12v battery. But I needed gas and went to a station and turned off the system ICE out of habit. Sure enough, the system wouldn't go back into Ready but would go from Park to Neutral. Since it was rain hard now, and I was calling my road service, I ask for a Flat Deck Tow home rather than a jump start.
As soon as I got off the tow truck I put my battery charger on the Yellow Top and it only read 11.7 volts. It's still on charge now. Now I'm wondering why the power conversion system wasn't charging the 12 volt battery or is my 1 year old Optima bad?? Or is there something about my driving conditions/plug-in conversion that is effecting the charge of this battery. I did a 2400 mile road trip to So. Calif and back to WA without any problems. Car has just 98169 miles right now. About 10k miles on the Plug-in Supply conversion.

I have a 2005 Prius with 110,000 mi. Sometimes when I accelerate the ICE (gas engine) simply spins (as if the clutch was slipping in a convention car) and there is little acceleration and the gas engine doesn't shut off when coasting or braking as it always has in the past. The battery screen shows it is not charging when this happens and is at 1 bar (purple). then sometimes the hybrid battery gauge will go from 1 bar to fully charged (green) in under a minute or 2 and then show discharging just as fast which isn't possible. It goes away after a restart sometimes but then happens again soon. Is it the TP sensor, Hybrid battery computer or ? I have gotten all kinds of codes including P0a93, P0a80, P1400, P040a.

why the engine keep running but no charging and no driving? the car was down hill, the battery was fully charged (green), I did not accelerate ( my foot was not on the paddle), but the engine sometimes keep running with a very low gas consumption. this become more often in winter, even when car stopped. I would like to know is this normal for Prius or there is any I can do to improve this?

I just got a 2004, it did have a bad 12V battery which I did replace, still not charging.But First it is making a loud noise under the hood sounds like towards the right side.when I accelerate starts at 18 to 20 miles per hour. Tried sitting still with car in gear and pushing accelerator can not get it to make the noise that way, without the wheels rotating.

I don't own a Prius, but my parents own two identical 2002 models (each with 120k miles).
My mother's car wasn't driven for nearly a month (hip replacement), and when they tried to start it last week, the ready light would blink 3 times - but no cranking.
After taking it to the dealer, they were quoted $4600 to replace the traction battery and ECU. We did the mandatory research on rebuilt batteries, but with only a vague diagnosis from the dealer, we were not convinced that this was the (only) problem.
So, my brother and I decided to swap the ECU, then the battery from my father's working Prius to my mother's - thereby proving the issue. Upon removing the 'dead' battery from mother's car, I decided to open the module, and check each battery. We measured anywhere from 3.0 to 6.4V on the individual cells - and 7.0V to 11V on the paired cells. It was clear that the batteries had discharged unevenly. The total charge remaining was about 151V - still above the 40% SOC minimum I'd read about.
We then bought 5 x 10A chargers from Walmart, and connected each to a pair of modules. Set the charge to rapid (10A) and waited 30 minutes (or until the charger indicated full). After 2 hours, all 19 pair were charged fully - with each reporting 15.7V +/- 0.5V. The total power was about 295V.
We reassembled the battery, re-installed it, and the car started immediately. We let it sit running, until it cycled off on its own. About 5 min later, the ICE fired again to charge the 12V battery - but it threw a P3006 error code. It showed a PS + MAIN + battery icon on the MFD. Using an OBDII scan tool, we cleared the error, and drove the car for a few miles. The error code did not return during that drive - but did one more time after letting it cycle off/on automatically. After clearing the code a second time, it never repeated again.
My assumption is that the 300V HV charge was above the 80% SOC and it didn't like that. But after a few cranking cycles, and the tendency for the battery to discharge back to it's rated output, the error no longer repeated.

Is there anyway to charge a couple of batt cells by running the car.
Just replaced 2 packs and there voltage is 2-3 volts lower than the rest of the batt packs? the ones replaced are at 14.5 to 15 where the others are at 17-18 volts.

Have a 2009 with 25K on it, purchased in April when they were practically giving them away. Recently did an oil change and got snow tires, then left my husband in car with heat on for 20+ minutes, and now mileage is in the 30's and the battery isn't charging itself or regenerating. What could be going on?

Right now my husband and I are driving from San Luis Obispo Ca to LA and back in a day. We noticed right before the grape vine on the I5 that the engine was really working, even on flat ground. Looked at the battery and it was purple. We have been driving for about 2 hours averaging about 70mph on mostly flat land. The battery finally charged itself on the big downhill of the grapevine (I5) but we're noticing we're running right through it again unless we start to break more. So, it's not getting any recharge during driving, just breaking. Can it be the generator? What causes this?

Meant to post this for a while but on both the Prii C's I have owned, I mostly only see the arrow on the HSI going towards the battery and not the other way to assist the engine. My wife watched it while I drove the last 2 days and it never went to the engine except when driving in EV.
On my regular size Prius I had, I saw it going to the engine way more than the C,

As I'm not driving my car, will leaving the engine idle for an hour:
1. charge the battery sufficiently each few days?
2. run the battery down
3. cause problems as no revving/load bearing on engine

I was wondering how I would charge my gen 1 battery cells and balance them with my IMAX b6 lipro battery charger. Every time I try to charge it or hook it up the thing keeps saying "input vol error". Now I don't know if that means I need a different ac adapter since I'm now using a 19.5 v laptop charger and most of the time they use a 12v ac adapter.
Most of the cells have a reading under 6v but we have 38 new cells coming in today. How we can balance them with this charger because I know it has a balance charge setting for the lithium batteries. That has a separate plug though. Should we just put the cells closest to their voltages and have them balanced that way?

My 01 Prius is not charging the 12V battery and I have error code P3001. Everyone on here said P3001 is the HV battery ECU. (which I replaced with one from the Junk Yard and still get the error code)
I charged the 12V battery over night and Autozone says that its ok. They tested it with a little machine. The only other thing I can think of is that the Inverter DC-DC converter part is bad. How I can test that? (is there a way other than replace the inverter?)

My dad's Gen III has been sitting garaged for almost a year now, and of course the 12 volt battery is dead. Firstly, it's sitting in a one car garage, and secondly I have a Gen II so a straight jump isn't possible. I have a trickle charger that should be able to bring the 12 volt back up in 15-19 hours, but here's my question:
Maybe I'm being lazy, but I'd rather not deal with climbing in the back to release the hatch and running an extension cord so I can get the charger close enough to hook straight up to the battery..

I just bought a 2012 Prius c. There are oftentimes when I don't drive my car for a few days. When this happens, I have heard that the car might not start, especially in the winter. Is this true?
