Reconditioning Experience with Hybrid Automotive's Prolong System

I have a Deluxe set for the 2004-2009 Prius I would rent out. I am in the Milwaukee, WI area.

Note: The discharger is the model for 2004-2015 Prius. The charger is for 2004-2009 Prius, but I read that it also will work on 2010-2015 Prius.

 

1) I'm also stopping between Cycle 2 and Cycle 3 (before the final discharge and charge). Should I recharge before the final discharge and charge, or can I just start the discharge?

2) My battery reaches 241v before leveling off. If I keep charging it, it will slowly reach 244v over a long period of time (6 hours), and will eventually reach 246v over a total 48 hour period (rebalancing).

At what voltage can I consider it charged for the first 3 charges (initial charge and first 2 cycles)?

3) It is recommend to wait 30-60 min after charging before driving the car. It occurred to me that plugging in the Discharger in Idle mode will run the battery fan during the cooling off period. Any problem with that?

4) What's the difference between the Charger for the Gen II and Gen III Prius? You have various "CO-PR" versions.

Thanks

 

Yes always charge at least a few hours after a discharge, or the battery not only can be too low in voltage to start the car, but can be damaged by the high amperage charging done by the car (High amperage charging should not be done to a deep discharged battery pack).

Once it reaches 241V and levels off, the charging is done and the balancing has begun. I recommend balancing for 4-6 hours for best results. Longer doesn't harm the battery, but the benefit delivered by the extra hours starts to taper down.

Yes you can plug the charger in. In fact starting a discharge and running it for 20-30 minutes is even better, becacuse that will pull the pack down into the 'normal operating range of the car' faster (which is the 80% - 40% SOC range)

The CO-PR is identical for Gen2 and Gen3 Prius. Our website has an issue that requires unique SKUs for every single product, otherwise they would have the same part number.

 

Is it difficult to build one yourself?

 

@jeff652 would say so. He has built his business around consumer and professional versions of the grid charger and discharger.

 

In theory, all you need is a charger (at a set voltage and amperage), a discharger (like the 2 light bulb one), and a volt meter. Then you can do it all yourself … manually.

If you want to avoid having to babysit the Prius, then you need a bunch of controlling circuits. That is where it gets much more difficult.

 

I'm looking for a Prolong Charger for my 2007, 216K, Gen 2 Prius that I'm trying to keep on the road for a much longer time!! Getting ready to replace the catalytic converter and O2 sensors to pass the state emissions and have noticed that my traction battery isn't as robust as it has been before.
If anyone has one they're not using anymore and wants to sell please send me a message.
Thanks!
