Prisu 2013 69k mile battery check hybrid system battery error P0A80 error

User is temporarily (2 years?) in Sri Lanka with a Prius imported from Japan.

 

You were quicker than me but I cited my sources.

 

I took a quick look and then got in a hurry.

 

LoL Prod

========================================================

Brad, I searched and will again for that video. Really did.

Anyone know where to find the vid of a guy in a rascal scooter explaining the hybrid battery? It's an hr long and really good and well done.

Would help here, a lot.

 

Here's the one for the 2017 battery.

 

And the Gen 3. It's over an hour long.

 

That's it, Jerry! Thanks so much!


Brad, invest the time, kick back with a cup 'o something and watch this. It's really great and helps a lot. Had I seen this before buying a new battery for the last car. I would not have bought a new battery in the last car

Thanks again Jerry. I wanted to find it for my own stuff as well.

 

good idea, how much longer are you staying?

 

That's not going to do anything. The car's computer will not let him completely charge even one cell, much less all of them.

 

Not to mention the cells are connected in series so the charge/discharge current in one is the same in all. That's never going to correct an imbalance.

 

Not exactly.
Although the current is the same, a charge level above the Prius limit of 80% for an extended period of time can reduce a voltage imbalance.
This, along with smart deep discharging is the basis for the Prolong gird charger & reconditioning system manufactured by @jeff652 here from Hybrid Automotive.

 

So if I select reverse, rotor lock MG2, and let MG1 generate I can reasonably expect to correct voltage imbalances by pumping the same current through all the cells, the capacity of which varies or else I wouldn't have the imbalance in the first place?

 

True, and a good clarification. I was assuming that @taxibuddy meant charging as the shop was doing rather than with a Prolong.

 

Not a chance. When the cell with the highest charge hits 80%, the car will stop charging. The ones lagging will never be able to catch up. You must use an external charger to force feed them.

 

No. The Prius ECUs limit charge of the pack to between 20% and 80% of capacity.

Rebalancing involves charging & discharging outside those limits without reverse charging any modules.

 

that should be your strategy then, finding a product and company that can get you through for a reasonable price.

 

Without properly testing & balancing the pack it is basically blind luck when another module will fail.
