Prius (2010-12) :: How Long Does Traction Or Hybrid Battery Hold A Charge
I've noticed that after sitting over night my battery for the hybrid system is not charged enough to operate the car in EV or for the first mile or two it does not seem to use as much electric power to supplement the car. After a couple miles it is charged or near charged and I see more use.
View 5 RepliesPrius (2010-12) Fuel :: Charge Traction Battery While Stopped In Hot Weather?
On a hot sunny day, occasionally I have to be stopped for extended periods with the A/C running which means the engine will come on for a few minutes out of every 10 minutes or so. to charge the traction battery. Engine comes on at 2 bars and goes off at 3 bars.
As engine efficiency at idle is low, would it be better to put it in D with the brake firmly pressed and push the accelerator so that the engine speed is in the high efficiency range so as to produce more charge for the fuel burnt and maybe also I could charge it to a few more bars on the battery indicator?
Prius C :: Cannot Charge Traction Battery When Car Is In Neutral
Took my C to the local drive through car wash as it was pretty crusty looking from all of the rain we've had lately. I had my A/C on as its a nice and warm sunny Florida day. Pulled inside and put my C in Neutral to go through the wash and half way through my car started beeping like mad and flashing the "!" in a triangle symbol and on the small screen it said something to the effect of "Cannot charge traction battery when car is in 'N'." My HVAC system drained down the traction battery and since the car was in neutral the engine couldn't keep it above the minimum SOC level. Turned the air off and anxiously waited for the car wash to hurry up so I could put it in drive. After I put the car in drive the SOC read 1 blue bar and took FOREVER to charge back (or perhaps it just seemed that way because I was freaking out..)

I see this was discussed back in 06 but not resolved. Maybe more owners have had additional experiences with this.
View 18 RepliesPrius (2004-09) :: Losing Traction Battery Charge In Morning
I have a 2005 Prius with about 170,000 km on it. I bought it two years ago used at 150,000 km. Everything worked fine for about 8 months, them I noticed the main battery started to drain on first start in the morning after driving a short distance. It would drop down to about 2-3 bars most days, especially on cold mornings. After reading on this forum for a bit I turned off the key locator, and it went back to normal for about 6 months, at which point it started dropping again. I haven't had any warning lights come on yet.
I replaced the 12 V battery, as recommended here with an Optima Yellow Top, even though the original one showed no voltage drop. It actually tested higher than the new Yellow Top I got. My fear is that the traction battery is losing modules. I'm planning on testing them soon.
Prius (2004-09) :: Traction Battery - State Of Charge Drops To Red In 20 Minutes
A month ago I bought a 2007 Prius with 140,000 km. I notice that the state of charge drops into the 'red' bars within about 20 minutes of the car switched on, in Park with no accessories running. A mechanic connected his diagnostic computer and saw 2 cells are low. However, the mechanic informs me there is no value in replacing those cells as others are likely to go down, thereafter. Is there anything I can do to avoid having to replace the entire traction battery?

I recently purchased a used 2007 prius. The car has not been driven for some time. I won it in an auction from a used/wreaked car lot and am in the process of fixing it up. I need to know if it is possible to charge the hybrid battery when the car is idling or will this only discharge the hybrid battery and if so, is there any way to charge the hybrid battery other than driving the car?

My 2007 Prius has 120,000 miles. I live in a mountainous area. I need to climb 3 miles at 6% grade to get out of my neighborhood. Lately I've been noticing the traction battery loses charge fairly quickly and I've been thinking about replacing the battery. Much of my driving is in steep hills and I run a full charge cycle many times a day, so I guess I should expect some loss of life.

Seen the battery charge level at 100%? The battery charge display seems to never go up to the top bar. I think I may have noticed it once, but I might have been dreaming that.

Should I be concerned..I have been noticing my battery is charging down overnight. I checked and all lights are off. It does charge immediately in the 10 mile I drive to work..but I am concerned why overnight it should be discharging.
Another Question - The right/left indicator sound is very muted..is that normal? Like, if I have the indicator on to merge into traffic, I am not sure it is as I can barely hear it chirping..
Prius (2010-12) :: Traction Battery Keeps Getting Hot
This is my first year driving my prius during a hot season, and for past 3 weeks my mpg has dropped from 49 to 41-43 mpg, and the reason is my traction battery keeps getting HOT! I can hear the battery cooling fan turning on constantly at max when i reach 20 mph, my car doesn't want to start in EV mode the engine just kicks in no matter how light you press the throttle, the EV motor is not assisting with the engine, the infamous slow rpm drop keep occurring and I when to touch the traction battery case and it its HOT, Ive open up the case to check for any dust on the fan and ducts but so far its spotless. I really wished they place an AC vent for the battery because the back passenger area with full A/C doesn't t get as cold as the front dose which doesn't cool off the battery.

Purchased a second traction battery and installed it in parallel with the existing battery? Perhaps one from a wrecked Prius.
I'm thinking that would double the Ev range, which would be very handy in my current commute due to long term construction on one of the highways I use. I am in sub-5 mph stop and go so long each day that I wear down my battery and the ice ends up running while stopped, thus killing my hypermiler goals.
Prius (2010-12) :: Traction Battery Cooling Fan Come On
How often should the traction battery cooling fan come on? It started to be warmer here in FL, and I hear this fan more often now. I bought my 2011 in December and up until now almost never heard this fan working. Now it comes on at least couple of times a day, mostly under heavy acceleration in Power mode.

My prius is almost 5 years old and has 88K Klm (49K Miles) My battery has gone down to one bar of late. This never happened until recently, never went below two. The bars seem to fluctuate up and down much quicker than before. My mileage is slightly down but it could be because of other reasons. Does it seem that there is something wrong with the battery? No warning lights are coming on
View 14 RepliesPrius (2010-12) :: Traction Battery Fan Running More Than Normal?
Long time since I have posted anything here, but I noticed the fan running far more than normal here. Now the outside temp was fairly warm, but the most recent day I noticed it, the temps were only around 80-85 degrees out.
I usually don't run the AC in my car unless it is terribly hot out - so when I hear a fan running it stands out to me. It is very obvious that it is coming from the rear seat vent area.
The temps here have taken a dip (highs tomorrow are only about 70-75F), so I will keep an ear out for it to continue. Is this something to be concerned about? It is a 2010 Prius IV with about 32k miles...
Prius (2010-12) :: Engine Rattle / Knock When Traction Battery Low
So I have searched about engine rattle/knock and I have found lots of results for cold starts but I haven't found it for the issue that I am having. I have a 2010 and anytime the battery is real low, around 2 bars and the ICE fires up to charge it, any time I give it a little throttle input, I get heavy valve rattling. It doesn't matter if its cold or hot, it does it as long as the battery is low. I never get this noise when battery is charged up, only when low. I have a link to the video below and you can see once I give it some input, it starts to sound like an old diesel tractor. Prius has close to 200K on the odometer and all my maintenance is up to date. Please turn the speakers up but the noise is right at 5 seconds in or so.
View 13 RepliesPrius (2010-12) :: Hesitate Upon Initial Acceleration - Low Traction Battery
I have had my 2010 Prius 2010 for a year now. I have been taking my Prius to a full service car wash with the conveyor belt. They have always seemed ver Prius savvy. But the last couple of times, after getting in the car and driving away, the car seemed to hesitate upon initial acceleration. Then the problem goes away.
The last time I took it to this car wash, I sat in the car, because I only needed the express exterior wash. About a third of the way through, the instrument panel said "Low Traction Battery... put into Park" I did not obey the warning because I was afraid of putting it in Park while the conveyor belt system was pushing my Prius along. So I ignored it. By the end of the car wash, the engine had shut down. I had to start it up and drive out, and I got that same momentary, initial hesitation as I accelerated, like before. The hesitation went away after that.
