Gen II Prius Individual Battery Module Replacement | PriusChat

A couple hundred can be knocked off that $3700 price, as dealers always recommend replacing the battery ecu controller, that is under this battery cover. I have read of others not replacing it and being fine. Your choice.

 

Happened to me about 2 months ago. I haggled with the dealer for a bit and then asked them to contact Toyota and ask if they would cover since the mileage is less than 80k. Toyota replied that they would cover 50% of the cost of the battery. I got out of there for around $1,850 total. I was originally quoted $3,200. It does not hurt to ask.

 

threx, if you were closer, I would do the battery charge/discharge cycles for you. I have the setup. just put it away on Sunday.

 

Greentec Auto has great prices as well as extended warranties at a great price.

 

I am not really interested in selling since I have 4 hybrids in the family to support. It has already saved us near $6000 instead of paying dealer battery installs. Also, since I only replaced bad modules, it is more likely to have problems in the next year or 2. I want to keep the chargers for when I have to replace other modules going bad. Mine being a 2005 w 294K miles.

My setup I got from lamtech. It is 3 Thunder T6 chargers with 3 400watt PC power supplies. also had all wiring to charge discharge 12 modules at at time. In addition, enough wiring to connected all 28 modules in parallel.

Minimally, I would recommend you get at least 2 T6 chargers or equivalent from Hitec. Most of these chargers are clones of one another. Just get the cheapest source you can find. The cheapest I have seen is about $110+10 shipping for a 4 channel charger. I assume you have a 12V battery and 12V battery charger at home. You can use this setup to supply power to the T6 charger balancers. This would cost you around $120 times 2 and cost to create the wiring. Should be way under $300 for the setup. This was the setup I was going to make until I saw lamtech selling his set. Not having to cut wiring just saved me time. Let me know if you need specific pictures. I have upload the ones on my phone. If I was making the wires myself, I would have used black wires for the negative to make it more clear than just having black ends.

 

no, grid chargers are low amperage chargers with high voltage. The setup I have is for charging and discharging the modules individually. Grid chargers are meant to be use while the battery is still in the car. Basically balancing them by overcharging the whole pack(in series) at a slow rate. 2 different concepts you need to understand before just buying things.

 

Would it be correct to say Grid Charger best for "simple" maintenace on a working, fully assembled, HV Battery pack. Also, great for someone who doesn't drive much and for a hybrid that will sit for a long time, resulting in a slowly discharging HV Battery.

This is for REBUILDING the whole pack, when it is known module(s) is/are bad.

 

You can use a battery charger balancer (grid charger) for preventive maintenance or rebuilding
Much quicker to charge the entire pack at once and let it balance at the top rather than doing modules one at a time.
Plug it in one time and let it go for a day. Done.

It would be a tedious process to use small hobby chargers to do maintenance charging. I can't imagine a casual user opening up the hybrid battery and attaching 28 (or 38!) leads just to do a routine balance. But a casual user could easily attach the harness to the charger, and then plug the charger into the wall.

Hobby chargers are interesting, and helpful to a point. But don't provide the ease of use most people want/need. (did you see all the wires from post #10 using hobby chargers?)

 

If you have a single module to bring up, fine, use a small hobby charger.
Use a hybrid battery maintenance charger when doing a whole pack. It's faster and less connections. Plus you only have to install the harness once.
You can come back and rebalance in the future just by a twist of the charger' connector to the harness.
