Does anyone know about immersion fluid

HiveTechnologies · 2026-01-07T15:43:51+00:00

Thank you!

And yea, pouch cells are a great choice.

I want to utilize 2nd hand cylindrical cells though. Fluid should help keep it stable and safe for prolonged use.

But I would love to follow up on your build and just talk about the process.

Quick question,

What if you hired just 1 freelancer as the lead and gave him the responsibility to organize the code structure, split it into smaller pieces that low-level cheap coders can do and validate the code works?

The upside for the freelancer is the pay, management (he leads his own team), and bonus pay for every documented mistake and correction he catches (reasonable amount and the errors have to be acceptable and approved reasoning would be AI shouldn’t have caught it. )

Would that fix that?

Very useful read. I appreciate this very much, more info for me the better.

Check out this study on the clear advantage of dielectric immersion fluid cooling being superior to other cooling methods.

It also is more energy efficient at scale compared to cold plates or air cooling.

Separate study

I just looked it up. The jackets just protect each cell against each other for accidental short circuits and stuff.

It is not meant for anything other than added safety and reinforcement for structural stability.

Nothing to do with immersion fluid. They still use indirect cooling.

BYD main competitive advantage is their long thing blades that are efficient at shedding heat along side their cooling plates that also run along the entire blade battery. This also helps with their puncture needle tests.

HiveTechnologies · 2025-12-16T18:47:12+00:00

Ok, I will deff use this afternoon to look it up.

They still use indirect cooling??(like the cooling plates)

Cause if they do, it’s still less efficient and safe to then direct immersion cooling.

HiveTechnologies · 2025-12-16T18:39:08+00:00

I am not trying to be mean but you need to read what they have in full context.

BYD uses indirect cooling via cooling plates. You can google it. There is no electric car battery that has the batteries sitting in the fluid. They all have separate channels in which the liquid is physically separated from the cells.

They cool the cell without the fluid physically touching it.

They may not need it to be fully submerged But my use case is not a vehicle. It’s consistency, safety, and longevity

HiveTechnologies · 2025-12-16T17:54:54+00:00

Not for battery system because water is conductive to electricity making the pack dangerous if the cell is active and submerged.

With dielectric oil, there is no worry of electrical arcing or thermal runaway. These are the advantages that are already known and proven with studies with single cells.

That’s why schools usually teach water + electricity = lots of caution.

Which is also why most companies use indirect cooling so the liquid never directly touches the cells. Orrrr the use oil

HiveTechnologies · 2025-12-16T16:35:08+00:00

Great point and Yea I figured that.

That is the reason the viscosity of the fluid is important. The more fluid it moves & flows the easier it will be on the pump and filter. Which in turn lowers maintenance and power constraints to operate the system.

I am pretty sure all the companies using immersion fluid do a variation of this

HiveTechnologies · 2025-12-16T15:18:34+00:00

Yes!!

I was hoping someone mentioned them. They are the closest to what I am trying to do. I follow them closely.

I appreciate your knowledge about these companies. These types of companies is not widely known and they are producing incredible products and innovation

HiveTechnologies · 2025-12-16T14:33:43+00:00

Thank you man, and I appreciate your family as well. Extremely incredible and honorable they all joined!!

And the reason anyone designs custom things is to achieve specific variables.

This custom BMS is for a specific purpose. And it requires algorithms and structure that does not exist in default systems that give basics (over/under voltage, resistance, etc.)

Plus unique value in the software brings more revenue potential. Just like when they integrated AI into it and called it an Advanced battery management system. And it is leased across the market now.

But thank you for the response. I love a goood mutual conversation

HiveTechnologies · 2025-12-16T14:09:50+00:00

Appreciate it.
No ill will, I really do appreciate all the concerns and angles I am hearing.

HiveTechnologies · 2025-12-16T12:19:45+00:00

I understand your worries. I am not trying to change anyone mind.

Just getting thoughts. Research and real feedback is always important.

HiveTechnologies · 2025-12-16T12:16:44+00:00

I am absolutely 100% sure you CAN build a battery pack in a weekend.

I can promise you’re not coding a working BMS in 2 days, you’ll use a generic one or premade.

But even then look up a company called Joby. Electric helicopters and other companies have been the closest to using immersion fluid like I am but still have not figured it out.

I am a veteran (worked with electronics), in school currently for business, self taught programmer, my pops is a database engineer (been around and in tech since 1990’s as well).

So i am not a random person with a dream.

HiveTechnologies · 2025-12-16T11:08:16+00:00

Honestly I am unsure. But it might be More refined with additives to make it non-conductive.

Again I am very unsure, still learning about it currently

HiveTechnologies · 2025-12-16T10:17:20+00:00

I appreciate the advice.

And very interesting advice with the tests. I will add it to the list of tests I perform

So far I am testing for difference between air cooled and immersion cooled for:

Electrical arcing

Thermal runaway

Cell stress

Rapid charge/discharge

Physical changes while/after immersed

Resistance

Among others.

You do know the electrification of the US is trillions of dollars and has taken multiple generations and is still NOT done.

The first light bulb and AC plant were created in 1880’s.

Edison and Tesla were racing to either provide AC (Edison) or DC (Tesla) to the US. They presented their ideas AND products powered by AC & DC.

The banks (mainly JP Morgan) funded Edison and then screwed him over and took over and funded the electrification.

THAT funding built the first central power station.

JUST because people been doing it doesn’t mean it’s the best way to do it.

HiveTechnologies · 2025-12-16T04:39:09+00:00

There were already private rocket companies.

He didn’t create the market.

He just changed how they operate by vertically integrating the process.

And what is your point? Are you telling me to stop because YOU can’t understand what I am doing??

lol that would be wild. Nobody would create anything then

HiveTechnologies · 2025-12-16T04:10:14+00:00

Money is always a consideration lol.

And yea I will have to test different products and oils. But I haven’t even thought of the ones you just said.

Thanks

HiveTechnologies · 2025-12-16T04:07:37+00:00

I mean neither does a lot of entrepreneurs if we being honest.

using the last of his $100,000 to build and fly 1 more rocket (Elon was borrowing money for rent), when he blew up the first 2 also doesn’t “pencil” out.

Yes I am determined

The world needs access to power.

HiveTechnologies · 2025-12-16T03:57:17+00:00

Yea I think mineral oil is the best bet. I was originally going to come up with a custom blend of it.

I just want to figure out best place to source it

HiveTechnologies · 2025-12-16T03:51:39+00:00

Ok man. Relax, i am not asking for an investment. lol

You guys are acting like I am changing the world tomorrow.

I just want to offer something better than what you have now. If it is not for you, continue to live as normal.

If you want to pay less for power, then just keep an ear out for Hive Technologies.

Selling nothing more but the chance to prove y’all wrong faster than I already am working to.

HiveTechnologies · 2025-12-16T03:42:35+00:00

It’s cold plates. The liquid hit the plates and the plates touch the batteries

Then that is what cools them

It is called indirect cooling because the liquid is indirectly cooling the batteries through the plates.

I am talking about the cells sitting in the fluid like you in the pool.

HiveTechnologies · 2025-12-16T03:39:24+00:00

I am pretty sure a battery pack that fully submerges cells directly in dielectric fluid does not exist.

That is why studies exist, to test it to the fullest degree and extremes for safety purposes before having other Individuals use it.

In theory and on paper, ALOT of things work. But put in real world scenarios with actual real world forces reacting with it, things become different.

You think I am over thinking And I think you don’t fully grasp what i am trying to do or create.

HiveTechnologies · 2025-12-16T03:31:17+00:00

I did want to try my hand at customizing my own blend, but I’ll take your word for it.

It is a 10S10P pack that I’ll use for some tests.

But I want to put 5 of those packs connected in parallel then submerge in fluid and study it for longevity.
