I feel that I press the gas pedal less when the battery is at high level to get to same speed than when the battery is at low level. Is it true? I am operating in Eco mode, but I am staying in ev region with ev indicator on during the comparison. High means 7 bars, low means 3 bars.
View 8 RepliesI just bought my new 2010 Prius the day before I went on a 300 mile trip out of state. Dealer showed me the eco mode, which sounded like a good idea to me. Drove on the expressway, about 70 mph, decided lots of power was not necessary and I wanted the best mpg so I put the car in Eco mode. Drove great for about 250 miles, then all of a sudden, I began to lose power. Fortunately, I was nearing a rest park. Pulled in, was there long enough to take care a Rest Park business, started back up and car ran fine. BUT I did not use Eco mode. Question: When should I use this mode and when should I not?
View 11 RepliesSeen 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.
View 18 RepliesRecently installed a curt trailer light. I modified the V plug in harness to work with the C.
I noticed the fan was running louder then usual. I took the right rear panel off were the HV exhaust vent it and there is no ducting from the factory.
The battery duct just goes to the back of the seat and vents out in that right corner right behind the 12V.
It makes its way up and over the right rear tire tub then what ever comes out of the rear exhaust, just vents out with momentum from down below. No duct guiding it from what I can see?
I went back and zip tied a wire that was in the path to sides were other factory wiring runs.
This seemed to fix the issue after making everything neat?
Not sure what caused it but it seems to be from wiring that was in the way? When I run the HV fan with my SG and remove the shock tower assess cover on the passenger side. I can feel hot air coming out. This might be an easy way to get more exhaust venting for anyone that wishes to do that.
I notice on my MFD that my battery level never fills up to the top. I've seen purple when it's low, blue, and green when it's in a high charge state, but there's always a missing 'never filled in' space for another bar, though always blank.
I can let off the gas downhill with it already green and that blank space for an extra green bar never fills. It just stays blank. Is this normal?
The Hybrid battery level appears to be higher on my 2007's MFD, when compared to my Scangauge ll. For instance, the MFD will show the pack almost full, yet the Scangauge says it's only 67%. Not sure why this is happening. All I know, is that both gauges used to provide very similar data years ago.
View 8 RepliesAfter trying to check the water level in my auxiliary battery and not getting a clear view of any place to add water, I decided it was time to remove the battery so I could get a better understanding of how this was to be done. I went through the whole process of dismantling all the brackets, clamps and wires that were in the way, removed the battery and, to my surprise, read the warning on the top that said "Never add water" and "Do not attempt to remove cover". Oh well, I'm supposing this is an agm battery and I'm going to let "sleeping dogs lie".
View 13 RepliesMy prius battery just died overnight a few weeks ago because i left the door open. I got it jump started by aaa.
The battery level has been fluctuating when im driving. It would go up and down and not stay up while driving. Generally regenerates when i brake alot. I just got it serviced at toyota and they OK'd the battery condition.
Battery fluctuating during driving. Normal or not normal? am i just paranoid?
I got prius i-tech Australia (should be IV or V in US). I just noticed this morning that my fuel economy is better when I got 6-7 bars on battery level, and worsen if i only got 2-4 bars. Is it just my imagination or any explanation for it?
View 8 RepliesI own a 2005 Prius with about 145,000 miles on it. I love it. However, I've noticed that lately, the vent in the back by the window will come on and make a lot of noise. Some research has told me that this is the air vent for the battery that is in the back, and usually comes on when the temps are higher and the battery is starting to get a little overheated.
View 11 RepliesSo I changed my oil today and added about 9.8 - 9.9 quarts. There was just a little left in the second 5 quart jug. I carefully added some oil while checking the dip stick frequently. I made sure the level was just at (maybe a hair above) the top dot on the dip stick. After that, I went out for a spirited drive.
Now 4 hours later, when the car is relatively cool, I checked the level again. However, the level is now significantly higher than before. It's definitely past the top dot, not by a lot, but definitely more than before.
I have a 2005 with 165K on it. Just within the last 2 weeks, at start up, no matter what level the charge shows on the display, the HV battery will almost fully discharge and then come back up to full charge within a mile of driving. I just replaced the 12V battery thinking this could have been an issue, but it didn't change anything. The car never acted like this since I bought it in 05. When it drops to the discharge level, It running on ICE only, with the typical slower acceleration. What could be going on?
View 8 RepliesI have begun to notice that when I start my van each morning for the first time that it is reving at a higher RPM then it did back during the winter. During the winter it may have been around 1000rpms at start before lowering down after a few minutes. Now it is starting at about 1500 and then returning down to the lower level after a few minutes of warming up. Could the change in outside temps cause this?
View 3 RepliesRecently I started to hear engine pinging/knocking-like noise when the hybrid battery level becomes low like two bars and the car starts a charge cycle. I also hear it occasionally when I accelerate on uphill. Is this normal or should I take it to a mechanic?
View 2 RepliesHow long should 12V battery last in accessory mode?
View 19 RepliesEvery once and awhile when I take off in the c the car drains the battery like it gets stuck in ev mode. The ev light will be off and the ice will be running but from a dead stop take off, the instant Mpg will read between 50 and 75 Mpg till it drains the battery gauge .
After the drain it works normal charges the drained battery and might not happen again for a couple of hours or a month there is no time period it happens.
Does this sound like a normal hybrid behavior? That's what I thought at first but because of the inconsistency of the behavior.
After 2 days of not using my Prius V, the 12v battery was dead. I couldn't figure out what I accidentally left on. I jumped it following the instructions in the manual but right after, it went into EV mode and then it required to be jumped again. I finally got the engine revving enough that it stayed on. I had never really listened to the engine rev before, but while revving it sounded higher pitched and tinny as compared to my old 6 cylinder, German car.
Is this higher pitched, tinny, electric sounding revving sound normal?
Is there anything to worry about after jumping the car?
Is there a way to see the charge on the battery? (In my old car if you hit specific buttons when starting you could enter a diagnostic mode where you could see many readings, live the current battery voltage. It would also be great if the tire pressure reading could be accessed this way.)
Also is it possible to use the hybrid battery to jump the car?
I've been using the EV mode - the EV portion of the curve without pushing the EV button - to run around town and to maintain speed once I've accelerated to traffic speed. It really boosts the mpg numbers and I'm able to get 55-60mpg on my 47mi. Roundtrip mostly highway commutes (hills included). Without the running in EV it's probably 42-48mpg.
View 8 RepliesI've been driving a bit different to try and get some more mpg. I will pulse up to about 45 then let off till ev kicks in and keep the bar right at the verge of going into ice. I can usually cruise at 40 mpg doing this on flat roads while only using the battery. Although if I'm able to do this ev mode for a long distance my battery runs down then the ice kicks in even with the bar below the ice line.
I'm still only getting 50-51 indicated mpg this way but much better than the 42mpg I got just driving it... My route has some hill and my tires are no lrr so I'm think that's has some to do with my low mpg.
Question is does driving 40 mph in ev mode till battery runs dead then recharge with ice just to run battery down again coasting with ev do any harm to the battery?
I have a problem I can't figure out. 06 Prius with 105k.
Current codes: P3000, P3020, C1259, C1310, C1378
Car will run and drive but is in limp mode
HV battery fan is at full blast, but charge does not fluctuate
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?
