For the trolls

Do you think that Jack is "a little" upset with mudder's review of the v3 prototype Na -Ion battery?

 

Let's not have another thread that goes all personal. (Haven't watched the video, so maybe it already had, I don't know.)

 

Watch the video. I think that Jack needs to learn about anger management. I can't believe that Jack posted the video on YouTube.

 

I think it would be disingenuous to call mudder a troll.

Mudder is doing a teardown and commentary about a product. These types of videos are kind of ubiquitous across the internet.

The commentary on these videos certainly can be helpful for decision making and for product improvement.

I commend Jack on his entrepreneurship and vision. I recognize the hard work he puts in every day on his product and business.

Hopefully mudder's videos have identified items that can be looked at as constructive criticism. Taking it too personally would make it easy to miss the knowledge that could be gleaned.

While mudder may be a new name in the Prius community, he is well known for his decade+ work in the Honda community.

Mudder already has shown his ability to create a viable lithium battery product. It is for the Honda Insight community to convert their cars to Lithium. He didn't design the batteries, but did design the integrating hardware. It can be readily bought from one of the big battery suppliers. Additionally it is open source for the public to copy, modify and iterate.

Much of the lessons learned from that product could be used in a Prius version of the product.

I am worried about this posted video by Jack. It doesn't quite address some of the concerns brought up about the product.

More importantly, to me, it doesn't put him in the best light. It doesn't feel like the usual quality of Jack's other videos.

It appears like Jack has been served a cease and desist relating to warning Jack to stop privately making false statements about mudder's professional reputation.

Watching a video like this makes me worried that Jack may (inadvertently?) cross the line and create even more problems for himself if he doesn't follow his own advice to "calm down"..

Trying to remain positive for future product improvements.

 

whoa that video was crazy, the guy went just "ahhhhh! dont buy my product!!! wah! wah! wah!, not really good marketing

 

It would be nice if Jack would share his background and qualifications to be designing a retrofit hybrid battery pack. Is he or one of his contractors a licensed Professional Engineer (PE) or even a degreed electrical engineer? Is there someone risking his PE license by stamping the design documents?

Jack’s representatives who argue and post with discount codes seem less qualified from a technical standpoint but I would love to hear their qualifications beyond sales.

“Mudder” (John Sullivan) is the reviewer in question and is an electrical engineer with experience developing a successful lithium hybrid battery retrofit and understands the role of a battery management system (BMS) to protect the battery, the car and the occupants. He is also a PE.

Jack in the video above is certainly in the same business but not as successful and certainly does not understand the role of a battery chemistry specific BMS. As a result many of his products have been recalled simply to replace a simple analog temperature sensor interface.

Years ago when Jacks products were introduced to the Priuschat community, I and others asked about the interface and safety features, typically incorporated into a BMS. In general terms I asked how they intended to safely interface to the Prius Battery ECU. Their response was “it’s confidential” but the results proved to be unreliable and simplistic without any electronic logic or safeguards. In fact a later revision actually used analog circuits to smooth out voltage difference between modules, effectively reducing the standard Toyota ecus ability to monitor the battery.

Until a stable, proven and well engineered Prius retrofit battery solution exists, I recommend staying with oem NiMH. Or buy a Toyota hybrid with an advanced battery chemistry with a well engineered BMS included.
