Prius (2010-12) :: How To Get The Car To Charge Traction Battery Idling
I know car likes to shut off at 3-4 bar, but what if I want to keep the battery closer to full in order to get more power. Is there any way to tell the computer to keep engine running?

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 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..)

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?

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.

I got my car about 2 month ago, and i started to understand how she is working ( how the hybrid cars works in general ), in my daily trip, there is about 5 mile flat road, sometimes when I reach this road SOC shows 3 bars only and its not enough for EV that 5 miles road, but if the battery have more than 6 bars i think it will do the job, and if you will ask me why you don't charge it through the car movement, the answer is very simple, because I am gilding the car before getting that flat road, so, is there any why to force the ICE charging the HV battery?
View 12 RepliesPrius (2010-12) Fuel :: High Fuel Consumption While Coasting With Charge Available?
When I go out to do errands around town (I live right in town) I get horrendous gas mileage. Now, I understand gas mileage is high at the beginning of a trip, but for this long and this high and under these circumstances? I'm getting ABOVE 10l/100km when I have 80% charge available (for americans, that's disgustingly high MPG like, pick-up truck high), AND my foot is completely off the gas. Literally, coasting, or braking, and I'm still sucking up gas. What the heck?
Is this just because it takes a certain amount of time for the engine to run no matter what or something? I still don't see any reason for me to be eating up all that gas when my foot isn't even on the gas AND most importantly, I have charge available. Feels pointless for me to use my car for what I use it for 70% of the time, which is for quick errands around town at low speeds. Thought the prius was suppose to be a superstar for this kind of thing.
Prius (2010-12) :: Battery Charge Level - Never 100%
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..

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.
View 19 RepliesPrius (2010-12) :: Installing A Second Traction 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 8 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...
