Prius C :: Why Doesn't The Battery Ever Charge To Full Capacity

Why the battery never charges to full capacity in the battery level indicator on the LCD screen? It never goes over 6 bars out of the 8 bars so it only gets to be 3/4 full.

Prius (2004-09) Fuel :: SOC Dropped - Battery Status To One Bar

Today I went to the national car test (passed. but), when the car has been returned to me by the employee of national car test center I noticed one bar on the SOC. This happened for the first time.

Additional notes:

1) recently (about 4 weeks ago) I had to temporarily replace for second hand (20 bucks) 12v small auxiliary battery.

2) recently (withing last four weeks) I noticed high temperature in the boot compartment, I tried to investigate and the ducting leading from the HV battery was really hot, which means that my battery was really hot too.

I tried to explain this to myself that this might be due to HV operating at higher levels due to unknown state of the replaced 12v small aux battery (second hand product).

3) Today I noticed that technician at the test center used some spring assisted bar to press the brake on the car while he tested the car, I recon that maybe he have had powered off the car while doing so, is it possible that this might have contributed to the dropped SOC ?- it's just my guess.

I'm thinking to replace 12v aux battery to brand new battery and then test the operation of the fan and whether the temperature still rise. - is it good idea? Or should I just seek for the testing tool to determine the status of each of the modules?

If so, which testing device can handle this task? I heard from this forum about ELM obd bluetooth adapter. I use android device, would this be okay or should I look for another device perhaps scangauge?

Prius Plug-in 2012-15 :: Loss Of Capacity In Battery?

What is "reasonable" for the loss of capacity of the Prius Plug in battery? Ours started out with a max at 11.7 miles when fully charged. After 6,000 miles and 7 months it is down to 10.0 miles. This seems like an excessive loss to me. I have read the tips for maintaining capacity and we don't do all the them. e.g. we charge out battery asap so it will be ready for the next trip. Our schedule is not fixed enough to determine when the car will be needed next.

Prius Plug-in 2012-15 :: HV Battery Capacity Decreasing Over Time?

Back in 2012 when I first bought my PIP, the battery charge level as indicated by range was 17-18 miles. The energy to fill the battery has been consistently ~2.5-2.7 kwh.

Earlier this year it dropped to about 15 miles. And just recently it's dropped to about 13.5 miles. The weather has gotten cooler in the last few weeks here in SF, so I don't know how much of this is seasonal as I haven't been keeping track that closely.

I expect to see charge capacity loss over time for the main LiON battery and would like to know what to expect and if my PIP is typical. How much further decrease should I expect in the next couple years? Is your PIP doing better or worse than mine?

Prius Plug-in 2012-15 :: How Fast HV Without Battery Capacity Decline

On page 93 of the Prius PHV Owners Manual, under the heading "Capacity reduction of the hybrid battery (traction battery)" is the following language:

"By observing the following precautions, battery charge decline can be suppressed."

"Avoid driving near the top speed for EV driving ( --P.40)"

To me this says don't drive EV 60 MPH, don't drive EV 55 MPH, maybe 50 MPH is OK is not uphill, probably 45 MPH is OK.

The manual also says "Also, if the hybrid battery (traction battery) capacity reduces, the EV driving range decreases. However, vehicle performance does not significantly become worse."

I wonder if this is a statement that the warranty will not cover capacity decline?

Prius C :: Battery Doesn't Seem To Charge All The Way

I've had the car for about 24 hours. I love it so far. My one question seems to be that the battery doesn't seem to charge all the way up. There seems to be room for 2 more bars to be completely full. Is this normal? Something to be concerned about? How this works, but if it is supposed to be full to the top, I probably should go back to the dealer?

Prius C :: Any Way To Force ICE To Charge HV Battery

I'm wondering if there's a way to force the ICE to charge the HV battery, either while standing or driving. Currently, EV Mode kicks in while coasting down a hill, and I would rather use those moments to effectively charge the battery rather than trickle charge with what little gain that gravity gives me.

I know there was a way on other models to charge the battery while standing by depressing the accelerator in park (or in drive with the brake depressed), but neither method works with the 2015 Prius C. The battery continues to drain while the ICE runs in park, and it refuses to run in D or B while the brake and accelerator are pressed at the same time.

Prius C :: Does The Battery Show Full Charge?

I've had my C a week and a half and it is doing great, but I wonder if the system is ok. It has never shown the battery at 100%. My Civic would charge all the way quite often.

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..)

Gen 3 Prius (Audio/Electronics) :: How The 12v Battery Keeps AMP Charge

I am thinking of installing amp in 2010 prius. Question how is the 12v battery keeps its charge. I am assuming the amp will be drawing power from 12v battery. When the engine kicks on during driving it is charging the hybrid battery. I am afraid of killing the power from 12v battery.

Prius (Gen 2) :: Battery Didn't Charge At High Altitude

I recently took a trip up .and I noticed that driving up long inclines my battery just drained to practically nothing.

When I got to level terrain it'd charge but to not to full level. and for my entire trip it didn't ever really charge much. However once I got down to lower altitudes and drove to my home It charged right up and has retained its charge.

Prius V :: Battery Losing Charge Whilst Driving

I've bought a used prius v ,the mileage is now 72k and as of monday (2 days ago) the maintenance reqd light came on intermittently when I start the car. So, I checked and saw that this meant it was due for a service, no big deal.

I don't know if it's linked but Monday I drove about 360 miles and then last night (Tuesday) I noticed my battery drained quickly on a 7 mile trip , it went down to 2 bars (they became blue on the car display) and took forever to go back up. Then same thing this afternoon but funnily enough, not this morning.
