NexPower V3 hybrid battery unveil - Sodium-ion battery

What is the weight of the bz4x hv battery?
Does this battery use liquid cooling?
How can this all be implemented in an old PHEV?

 

It's big and heavy.
Maybe it won't need liquid cooling in Mexico, nor liquid heating in Alaska.
With a Hope and a Prayer. I hope it's securely bolted down...

But with the time and money spent on this project,,, you could almost just get a second job and buy an AWD EV ready to roll.

 

There must be some logic to the upgrade process.
It takes about a couple of gallons of gas to drive 100 extra miles. Load the car with hundreds of pounds of batteries instead of one canister?

 

you know... I stand corrected! Now I am trying to remember why my brain made that association.... and wow.. you there folks, this is why I love the forum, I know I don't everything and where I am inaccurate, yall keep me honest. Its gonna bother me now trying to recall how I came to that belief. hmm

 

Sure, let's break it down in a simpler, more conversational way.


So, you know how in 2013, a car with a 4.4 kWh battery could go for about 13 miles using just electricity? And by 2017 the same car, but with an 8.8 kWh battery, had a range of 25 miles? Jump to 2023, with a 13.6 kWh battery, you're hearing about ranges from 33 to 44 miles.


With these numbers, we can see that there's a sort of pattern. For each kWh of battery, you get roughly 2.87 miles of range (that's based on an average range of 39 miles for the 13.6 kWh battery).


So, let's say you wanted to figure out the range of a car with a 50 kWh battery. If we stick with our little "rule" here, you'd think 50 (kWh) times 2.87 (miles) would give you about 143 miles, right?


But you and I know it's not just about the battery size. The car's weight, its shape, how hard your foot is on the pedal, if you're blasting the AC or the heat, if you're off-roading or cruising on a flat highway - all of this stuff matters too.


So yeah, in a perfect world - a 50 kWh battery might get you 143 miles. But in the real world? Saying a 100-mile range is kind of like saying, "Hey, I've got some wiggle room here". It's a bit more grounded in our day to day reality.


I hope that makes it a bit clearer!

 

clearly you havent seen the size of the bz4x HV battery have yall?





where is hundreds of pounds when each of the four OE rack of cells was roughly 25pounds each and doubling the capacity by replacing the cells, the double capacity cells weight basically the same. with that.. the bz4x has well over 70kWh and i might just end up using all of the cells since using any less than whats in the case messes up the whole PHEV having the same number of cells to them wire up to the connector which fits the plugin battery ECU.

 

This doesn't clarify anything.

You haven't figured out how much the battery from the BZH4 weighs and how it is cooled.

 

I never said I didnt, its water cooled, the first actually. on the weight, its not a concern of mine, visually it appears lighter than my OE cells.

 

If you are upgrading your Prius, then the weight of the installed parts primarily concerns you.
Sausage is weighed by eye in the store, but here an accurate calculation is important so that the car wheels do not turn in different directions from the load.

 

look here..

this is my car with close to 1,000 pounds of added cargo weight, the suspension is built... notice the area above the rear wheels here and the car has no droop? I guess to say, sometimes what you don't know about what someone else has thought through might just be a little further outside the box than you are used to.

a dismantler tells me roughly 400lbs is the weight of the battery

 

To put it mildly, he was misleading.
Much more.

Also, without replacing the cooling system, you will end up with a suitcase without a handle that you will have to carry.

The most interesting question is - in which niche of the car will you place this upgrade? In the trunk, in the passenger compartment, on the roof?

 

Nice shots of the pack, thanks !
When you get inside the case please send some pics my way

 

maybe I didnt state it earlier... this is all on the 2013 PHEV Prius. you know how the entire trunj/spare tire area is a battery right? 4x the size of the non PHEV.. earlier I stated each row of cells is roughly 25lbs. I guess if you cant visually see the size of a PHEV battery then look at the bz4x battery with its fancy cooling then think, "ohh damn he has a point" then I dont know what to tell yah other then Ill show you when its done. I take it you havent tried to see whatll happen if x is done to a PHEV have you? The 2010-2015 PHEV system in the Prius is by far the easiest to mod and the system adapts. the only part in this that I might have an issue with is using the fast charging compionents from the Gen 4 Prime on the Gen 3 but then, me using the ECU from the Gen 4 to help propel me into that 80mph range in EV only might help me with the charging components. I wont know until I plug it all up and see tho.

roger that ghostrider!

 

To cram the uncrammable?

Where? On the roof? In the trunk? In the passenger compartment?

Have you ever wondered why the high-voltage battery in the BZ4X is located under the floor of the cabin and takes up space from the front wheel arch to the rear wheel arch across the entire width of the BZ4X?

Have you ever wondered why Toyota engineers use liquid cooling on this high-voltage battery?

Are you talking about the standard V3 Sodium pack? Because we've tested 4 of them (one guy having about 60k miles on his gen 3 already with it) and I saw the best MPG out of them compared to the GT version.

 

Oh, oh, can I take a crack at this? !!

1. Because it's a big modern Li-ion battery pack with TMS capabilities. The coolant loops are part of the pack build up, but not the Coolant pump, Heater, and AC compressor to heat or cool the pack, as required. Those are external systems that are required for a modern pack.
And this pack is a sealed unit, NOT mounted in the cabin of the car, for safety reasons.

2. Correction: the TMS cools or heats the pack, as required. That is how modern EV's and PHEV's handle keeping the cells in a happy temp range. This is one reason EV's surpass the 8yr/100k mile warranty with minimal degradation.

In theory you could just remove the modules/cells and MacGyver them into a Gen 3, somewhere, without any TMS.
I suppose the drive could then be tasked with the duty of watching module temps, and then what?
Not use the pack's power when the temps are out of the Happy Temp Range?
Having the modules/cells just sitting in the cabin getting cabin temp air gently blown through the pack may be fine for Hybrid duties.
That's how they designed the original Prius way back in the late '90's.
But using the pack for EV duties when the pack is really hot or cold is not ideal,, But it may work for a while.
Just don't let the smoke out.

Side note: MG1 in an old PiP may not be capable of spinning backwards fast enough for the car to go "80MPH"

 

Crazy people do what crazy people to.
I saw one guy that bought a 2005 Prius and decided to see if it could be boosted with nitrous, When he tried, just giving a bit of boost, he blew a hole in the engine. I think he picked up some oil filter parts off the road.

The first part of this video shows some of the engine damage.

 

Stupid is as stupid does!

 

You haven't seen my other leg work have you?

Differences between V and non V CVT? | PriusChat

its the sprage clutch and ecu that does the magic. One can only hope the coding to hold the chrge button and use ICE to charge the HV battery is also brought over...

ive really gone into the weeds with all this and after upgrading the cells in my PHEV... I tell every Plugin Owner I see on the road... "here is my card, when you are ready to sell or even if it gets crashed.. buy it back and ill buy it from you..." only because I see the only way to convert a non phev to phev is using phev components.

and now its to the point of buying jdm spec prime in canada then dismantling the parts I need and driving them all back with he car dismantled... just to get the parts I need.
