NexPower V3 hybrid battery unveil - Sodium-ion battery

Wow, that is big on the accusations, claims and the likewise, without much to back it up ..... When did the Chinese govt start testing products for sale to overseas markets?

With so many different sodium ion (Na+) cell construction methods and manufacturers, the number that are the real deal and the number that are failed production test runs are near impossible to identify one from another.
About the only Sodium ion cell that could be taken on face value as being thoroughly tested, would be CATL, and they don't sell to small enterprises, their second gen products are the cutting edge as far as commercial level production and OEM are taking these as fast as the pass CATL testing procedures, those that failed the testing are available on the open market .... not sure how much faith I'd put in them though, no one says why they failed to meet specs, they just didn't make specifications so were rejected.
Doesn't matter what letter of the alphabet they put on the claimed quality, it either passed CATL specs and went on to the OEM suppliers, or it didn't ........

Maybe you missed all the fun here at priuschat, on the two projects youtube channels and the other projects followers (beta testers) at the insightcentral forum last year (24). As well as the banning frenzy (timed and permanent ) that happened here as a result of all the fun.

@PriusCampers comment about rigorous was referring to the testing Jack has done and published on his youtube channel which you can find by reading the documentation on the projects web site.

 

Why does Nexpower have to survive?

My in house rigorous testing (driving normally for 2 years in CA) caused their $2000+ pack to fail, with the only recourse from the company being the "opportunity" to purchase a $980 sodium replacement. That's $3000+ spent for crossing 1/5 of the life expectancy of a sub-$2000 oem pack.

There are claims being made that sodium is better than lithium and won't fail the same way, but these claims are coming from the same people who made the big lithium claims years ago (yes I was foolish for drinking the koolaid back then).

Additionally, Mudder's videos show that certain design deficiencies that lead to the lithium packs' failures are still present in the new sodium packs.

I can personally say confidently that I would have been better off (money, time and anxiety wise) without Nexpower. I am willing to bet that the overall prius community would've been better off without them too with the reliability of oem replacement packs.

 

Exactly. They never had a convincing story and never answered technical questions from the beginning.

I remember jack azausa telling me that Toyota’s bms in the ecu will keeping the lithium battery pack within range. If so, then why does the nimh cells are out of voltage range.
