prius hv battery

bummer.

 

Thought you cleaned up the bars before the latest battery rebuild?

 

soap and water, q tips, small brushes, whatever will fit in there.

 

Our Battery Module Load Tester r has the H4 bulb wired in series to create the ~6A load. It's a great low cost way to identify failed modules:

Yes, agreed 100%. Our new ProlongPro Discharger will have an integrated 60A module load tester. This will be a much better simulation of what the modules experience when the vehicle is being driven. It will help find borderline modules much better than a 5-6A load will.

Here is our new automated pack discharger:

I think that you meant wired in parallel

You should probably add that information to your product description.

To use that 60 amp discharge capability to identify weak modules requires that you can read the module voltages while in discharge. A MiniVCI will at least read module pair voltages.

 

Is that a new product that has yet to be released?

I know of the consumer Prolong Battery Discharger, and the more commercial Prolong Intelligent Discharger, but nothing about a ProlongPro Discharger.

After looking around the website I found no mention of an integrated 60A module load tester for either of the above models, though to be honest I failed to read the user guide(s).

Thanks for the reply!

 

Aack, yes of course. Parallel.

The ProlongPro Discharger IR calculator/load tester will is used on one module at a time. It is separate from the 3A pack level discharging ability of the system. It reads module voltage while performing the test, no VCI required. It's designed to be used on a battery pack that is on the bench being rebuilt, fully independent of the vehicle.

The ProlongPro Rapid Discharger is a different product than the Prolong Battery Discharger. It's a 3A universal discharger designed for shops/professional users. It will pair with the 3A ProlongPro Rapid Charger, also not yet released. Both are on track for July and will retail for $1,695 each. We are deep in R&D now. Here is a feature summary from a couple months ago (we made some changes since this flyer was released):

how can you check out the hybrid battery?

 

The parts manager needs to get informed, the warranty is 3 years, if installed by Toyota. And in any case a 1 year warranty on a new battery from Toyota (for a non-Toyota install) is worth infinitely more than a three year warranty from a rebuilder on what amounts to be a collection of secondhand parts of unknown origin and quality.

I don't think you could do better than a factory new from Toyota.

The parts manager doesn't know what he is talking about. I wouldn't take advice from him.

 

I agree, I'd go for the new Toyota for $1000 more--you'll get ten more + years out of it. And be able to move it to another Gen2 if ever needed.

 

You can charge the weak modules if they are still over 7.2v. No need to replace good modules

 

I thought this also, until I saw a 138 amp discharge rate on Techstream while testing a newly rebuilt HV battery in my 2007. It was only 108 (or maybe it was 118 amps) when I did the screen capture. I was monitoring the laptop while my son was performing driving maneuvers as I requested. 138A appeared during a hard acceleration test simulating a right-hand turn pulling out into traffic. Needless to say, I was surprised.

 

It was during the 2006 model year that the SW parameters were changed to allow the higher current draw. So your 2007 should be expected to exhibit currents of the order of 130 amps. As with any control system, some short term overshoot will occur when the system is suddenly requested to provide high output.

I wasn't aware of that. Didn't think the jump was made until the Gen 3 models. That's interesting to know. Thanks.

If I were to put a 2007+ battery into a 2005, would that enable the 2005 to also draw 130?
