HV Battery not charging above 58% even with forced charge

Those measurements on Dr. Prius app always seem wacky... Please post some screenshots of what you're looking at... I use the total voltage in the battery pack to judge how it's doing in Prius app. A normal battery pack is going to be in 220v range.

 

he said dr prius works ok on his 2007 & his friends 2010 /

 

I've no doubt it's working fine... It's that the reading the OP is using are not the ones you need to pay attention to... If we could see a screenshot of Dr. Prius we could look at everything at once and be helpful... The test that Dr. Prius does are very rough estimates and can be easily wrong. You have to watch the data in real time. A video of the screen would actually be better than a photo.

 

This is exactly what I see when I put a brand new battery pack or after I've reconditioned a pack... The healthier/newer the pack is, the more steady the bars on the screen.

 

Well the best way to test this is if you climb up a mountain, once you go back down, as in a long down hill drive will charge up all the bars on the display...

I've never once read on here of someone with the problem of a pack not charging up all the way. If the dash lights come on, then you get warning codes that points to a problem. Or if the gas mileage is bad that would be another symptom of a problem... But if it's just not showing a full charge on the display, that doesn't seem like a problem.

Looking forward to what all the data on your Dr. Prius app says.

 

Maybe the car "knows" it will take forever to fully charge the battery when the car is idle, and doesn't. It's wasting fuel.
Toyota has done a great job of figuring out the BEST way to manage their hybrid.
Why not just let the car do what it's designed to do?

 

Why are you so obsessed with getting the battery 100% charged? It's not going to happy.
If the car is running correctly, why bother?
If you're still concerned, invest $700 and get he prolong battery charger/discharge and run it through
the cycles to refurbish it and give it a full charge?
Maybe you are putting TOO much faith in an "app"????

 

You’re correct asrdogman, if battery pack is at 100% charge your pack is full danger. In fact, the vehicle will disengage HV charging when battery pack is at 80% charge. When SOC is above 60%, you’r beyond the safe zone of charging but going a bit over is fine but discharge or use the charge when you can to be 60% or under.

 

Most of the time the highest mine goes is 2 bars shy of the top. But I can easily get it that extra bar.
And sometimes I can get it so just the 2 "leads" at the top aren't green. Every once in a great great while,
they turn green too! I didn't think they did, until I saw it. But it's only happened twice, MAYBE three times?
But it doesn't stay there long.

I don't worry about it much. I rarely go below half on the fuel tank, and try to have at least 3 bars when I
shut down for the night so I can start in EV mode in the morning or if I'm just moving the car, so the motor
doesn't start.

 

Everything looks great... That state of charge % number is a calculation based on the pack over time and, as always, it's not giving an accurate view of the health of the pack. In the upper left corner, you can see the pack is in the 220v range and individual modules are are near 8v each, which is up above 90% total charge, despite what the wrong number in the upper right corner says. The key number is the blade difference and yours is exceptionally low, which is good... Once that blade difference gets up above 0.4v you'll start throwing warning lights and be dealing with a failing pack. Enjoy your car... There's nothing wrong with it.
