dr prius lithuim modules problems

Welcome to PriusChat!!

You might check the HV battery ECU, both the orange socket and inside the case where the pins attach to the PC board.

Have you spoken with the dr lithium warranty department about this?

FYI : you're moderated until you've posted 5 times.

 

With the normal metal hydride battery once you start flopping back from fully charged to half mast to empty and back to full again very quickly unusually quickly like you've not noticed ever before that's generally your battery telling you there are problems with the lithium cells I'm going to assume similar The minute this started in one of my cars as soon as the battery was swapped out that stuff was gone

 

Greetings... When you installed the Lithium pack did you use new wiring for the voltage sensor harness ( aka: wire, frame, No.2)?

There's is a known problem that happens to a small number of older Prius that's caused by the corrosion that was created with the old NiMH pack. If you open up the inside of the battery ECU and find corrosion on one of the pins where the voltage sensor plug connects to the circuit board, that corrosion is causing bad readings of voltage. By cleaning those pins and replacing your voltage sensor harness you fix that problem. Also Nexcell has designed an upgrade kit for $100 that will not only prevent this issue from coming up, but it will also further boost your MPG.

 

I think the logical guess is that your replacement modules are not going to work out as good
as you had hoped.
But they will have to be tested to prove that.
Have you contacted the company that you bought them from ??

 

The electronics were engineered and designed for NiMh batteries with a 20 plus years proven track record. When and if I need a replacement, I'll get a brand new NiMh vattery from my Toyota dealer/

 

Indeed. Me too.
Not everything can be improved by having an "amateur" tinker with it.

 

considering Dr Prius makes an app, i would imagine they could get telemetry from the app and better analyze what the issue might be.

 

Yes, that's exactly what has happened... And despite selling close to 1000 packs less than a dozen have had this issue, but one of the main reasons they've been sold out for so long is that Nexcell takes these problems seriously and so they redesigned the circuits in the modules to eliminate the problem, which in this case led to a discovery that the new circuits that keep modules so perfectly balanced no matter what Prius battery ECU does that it has led a significant improvement in MPG has been realized, which led to further refinement of the circuits, which has led to more delays. But I can't tell you how great it is to work with people who don't cut corners and want to deliver the highest quality system possible even if it drives me crazy that I have so many people ready to buy while we wait for the next shipment of packs to arrive.

 

so what are they doing for the 1 percent of customers with this problem?

 

Everyone thus far has had their pack replaced under warranty, even though the problem has more to do with Prius battery ECU than than the actual performance of the pack. And in addition to that all existing Nexcell owners can get shipped the new circuit upgrade pack for close to under $100, even if they've never had an issue. And who wouldn't want an upgrade that significantly improves MPG?

 

Tell me more about how an amateur can do battery chemistry research and testing for 8 years and then contract with a factory in China to produce something for the the past few years that has been tested to same standards as major auto makers and then they keep improving on each iteration to ensure that even the most minor of product failure risk are addressed?

Perhaps you'd like to make a friendly wager about how almost all Prius built 2000-2015 that are still on the road a decade from now will be running on Nexcell packs?

I'll bet you $8 dollars? And we can set it up as a smart contract through the DAO so I automatically get paid by you in 2033?

 

The interesting part is last year the company would not share how they made lithium cells compatible with the existing NiMh charging algorithms. Just a lot of rhetoric about how well tested they were. Now the story is different "redesigned the circuits in the modules to eliminate the problem, which in this case led to a discovery that the new circuits that keep modules so perfectly balanced no matter what Prius battery ECU does..."

 

SO......that is what they are TELLING you. But how do you know that isn't just some made up fiction that
they are feeding you in an attempt to keep you happy ??
I mean how do you REALLY know ??

 

Scams come in all sizes and shapes.
Some of the perpetrators are really smart people.
And they can suck in fairly intelligent people to do their "marketing" for them.

This may not be one of those cases........but it sure does bear some of the earmarks.

 

funny how no one blames toyota when an oem pack fails early. they just say, '$h!t happens', it's under warranty.

 

Getting warranty is fine; being ghosted when needing the original order, support or parts is completely different. Why should a buyer have to ask on a forum rather than directly to the seller?

 

i don't see where the op posted that happening

 

Other than an improper installation, I've never once heard of a OEM pack failing prior to expiration of replacement pack warranty, what is it, like 4 years? As in EV cars are awesome because electric power doesn't require hardly any moving parts that can fail... I mean how many times in your life have you bought a battery that's defective right away, rather than simply failing a little sooner than normal after lots of use?

 

That's not true... For more than 3 years the owner of the company has been actively engaged in explaining all the details on here and elsewhere with nothing off-limits for discussion ever. Of course when I've tried to post Nexcell details on your Prius FB group you've not approved the posts because pretending like there's no transparency is how you perpetuate your nonsensical anti-advancement agenda. Not much different than Toyota explaining why EV cars are not practical and no one wants them. It's one dishonest claim after the next with y'all as the world advances while you just sit there.
