Hey everyone, and welcome backto the Edge Adverse Tech Cast.
This is your go-to spot for everything,nxp, software tools and enablement
specifically for obviously the MCUsand MPUs from nxp, and a little
bit of everything in between.
I am one of your co-hosts, Kyle Dando.
And I am Bridgette Stone.
(00:32):
Today we're plugging into oneof the hottest topics in tech,
and that's energy storage.
Whether you're thinking EVs, solarpanels, or backup systems for
your home or the factory, energystorage is at the center of it all.
And spoiler alert, NXP is right there too.
Helping make these systemsintelligent, safer, and more efficient.
(00:54):
And to help us break it all down,our guest today, we've invited
Marcelo Marques, our go-to expertfor Power and Energy Storage.
We call them our Technology Pillars,and Marcelo is great at providing
all the insight and research intowhat is gonna make NXP deliver the
best solutions for our customers.
So welcome to the show, Marcelo.
(01:16):
Before we jump in to our questionswe have for you, why don't you just
tell us a little bit about yourself.
Okay, Kyle, thank you for having me.
My name is Marcelo Marques and I'mthe global marketing manager for
the Power Energy Segment within NXP.
My focus is on Energy Storage.
Okay.
Marcelo, hardest question of the day.
Imagine you're stuck in an elevatorwith a very curious stranger.
(01:36):
How would you explain EnergyStorage to them in 30 seconds?
Okay, so let me think about it.
I would say, "Do you ever thinkabout how your phone stays alive all
day? Or, how do you drive electriccars and they don't need gasoline?"
That's all thanks to Energy Storage.
It's this new technology that let us saveelectricity for when we actually need it.
(02:00):
It's like a battery, but you canimagine on a very massive scale.
Another thing would be solar panels.
They are sucking sunlight andEnergy Storage is what led
us use that power at night.
So it's a game changer for clean energy.
It makes the Grid more reliable and ithelp us move away from fossil fuels,
(02:21):
which is the goal for Global Energy.
There is all kinds of energy storage.
There is batteries.
You can pump our water back to Dams.
You have compressed air.
There is a lot of innovationsgoing on, but what we focus on
at NXP is on the battery storage.
All right.
Well, that's excellent.
I appreciate that you madeit very simple and practical.
(02:42):
I think most of the listenerscan tie into what you shared.
So for our smart.
Yeah, so from our smart home...
so from our Smartphones to SolarPowered homes, Energy Storage is
quite the hero behind the scenes.
So why don't you expand a little biton that and talk about what some of
(03:04):
the trends are that you see in thefuture of Energy Storage systems.
Yeah, so let's talk a little bit about itbecause Energy Store is really hot right
now, and it's evolving really fast andit is not just about batteries anymore.
So it's going everywhere on cars,it's going on residential, it's
going on grid connected batteries.
(03:25):
And there are a few trends going on.
The first one that is pushing all theother trends is the Higher Cell Capacity.
So battery manufacturers are just packingmore energy into each one of the cells,
which means they have a longer run timesand you have fewer cells per system.
And of course that lowers thecost, which is always the goal.
(03:46):
It's really important for grid scalestorage because as you can imagine,
they need to provide massive amountof energy and current, and so
you need to scale up the capacityof each one of these batteries.
So because of these high cell capacities,the other trend, and it's really hot
right now, is the Active Cell Balancing.
(04:08):
Because before, with the smallercapacity cells, you would just
balance them by burning off theexcess energy of the cells in heat.
Sometimes you're going tohave variants between cells.
So one cells are gonna havemore capacity than other cells.
They're not identical because ofmanufacturing process, because
(04:29):
of the chemistry that goes oneach one of these batteries.
So when you charging them upand down, that difference needs
to be equalized or balanced.
With passive balancing, youbasically just burning that energy
from the higher voltage cell.
So you're wasting energy.
High cell capacities, you don't wannaburn a lot of energy between the cells.
(04:51):
You want to transfer thatenergy in between cells or
between the cells and the pack.
So this energy is redistributedbetween cells in real time, during
charge or discharge of the system.
That will improve theperformance in lifespan and it
will enhance safety as well.
It's something that customersare not negotiating.
It's basically a requirement.
(05:14):
Then the next trend is, again becauseof the higher cell capacities, the cells
are getting very expensive and theyneed to be reused or given a second life
after being used for energy storage.
It's called Battery Passport.
If you follow the European marketclosely, you see that this is now a
requirement in the EU starting in 2026.
(05:38):
What is battery passport, you may ask?
It's basically this digital recordand it tracks the battery materials,
the manufacturing history, theperformance, and the recycling status.
And this will be the static piece of it.
There is also the dynamic piece of it,which looks at the number of cycles of
this battery, the death or discharge,the state of health and et cetera.
(06:00):
It's like a digital birth certificatefor batteries, and it follows the
battery pack throughout its lifetime.
Then the next one, the last trendthat I am seeing around is the EIS.
Electromechanical Impedance Spectroscopy.
This is a diagnostic tool thathelps the manufacturers understand
(06:21):
the internal health of the batterywithout opening the battery.
So basically it's an X-ray ofeach one of the battery cells.
It detects early signs of degradation.
It helps with the safetymanagement and performance issues.
It enables predictive maintenance so youcan find out if a cell is going bad before
it actually goes into a thermal runawayor catches on fire so you can replace it.
(06:46):
And gives you better estimationof state of health and state of
charge of each one of these cells.
Ultimately it also helps witha better balancing management.
And that's important because if youwanna do perfect active balancing
for your entire battery pack, EISis gonna help you a lot with that.
So, Marcelo, you walked us throughfour trends, the Higher Cell
(07:07):
Capacity, Active Cell Balancing,the Battery Passport, and EIS.
How is NXP responding to those trendswith our technology and solutions?
Yeah, so the short answer to thisone is, uh, we're everywhere.
All in.
So we offer each one of thesetechnologies separately, or we also direct
(07:29):
support them in our reference design.
We have a roadmap of reference designs.
We have a few reference designsthat are in production right
now, a few in development.
Each one of them will haveall of these technologies or
some of these technologies.
It depends on wherethey are on the roadmap.
We support active cell balancing.
(07:49):
We currently have what we've beenhearing from customers feedback
as the lowest cost active cellbalancing solution on the market.
We do have a battery passport referencedesign implemented that communicates with
the cloud, communicates with your phone.
So you have not only the cloudmanagement for the battery passport,
but you also have a phone appthat will connect to the cloud.
(08:12):
Read from the battery throughNFC . Whoever is looking at the
Battery Passport, what is the currentstatus of that particular battery?
We also have EIS.
This one, we have the chips, but wedon't have the reference design yet.
That one is in the works.
But we have proof of concept in ourlab in Tellus France that shows how it
(08:33):
works, how we measure each one of theimpedances for the cells and how we can
predict thermal runaway and actuallycompletely prevent fires in a battery.
We think that one is gonna bereally disruptive and really
important for safety measures.
That's exciting, especially that we'renot talking about future capabilities,
(08:53):
but real deployable tech now.
With that being said, what do you thinksets NXP apart from others in this space?
A good question.
So when it comes to energy storage,what NXP really stands out by is
offering a complete reference design.
It's not just components, weprovide the full hardware design?
(09:14):
We give away the schematics,the PCB layout, the entire BOM.
We have a complete software stack.
That includes all the low leveldrivers, all the way up to the
functional safety manager, thebalancing manager, all the interfaces
to read data from the batteries.
We also have, in our microcontroller,we have an extra core that does
(09:35):
all the application layer tasks.
For example, state of healthand state of charge calculation.
So all this included in our package.
On top of all this, we offer thefunctional safety certification
for the entire system.
It's certified for bothIC60730, and IC61508.
(09:55):
Which means it's a SIL-2Class B certified solution.
That's a huge differentiator in themarket because it's going to give our
customers the fastest path to complianceand the fastest path to market and
reduce a lot their development risk ifthey just wanna accelerate their time
to market, this is the go-to solution.
(10:17):
On the trends, we have the lowestcost active cell balancing solution.
It's a very elegant solution andit can do balancing up to 10 amps.
On battery passport.
Again, it's a complete softwarestack that includes even the phone
app to connect to the battery.
And on EIS.
What differentiates us from everybody elseis that we do EIS for the entire pack.
(10:41):
While others are doing for each oneof the cells, we excite the entire
pack to extract the impedance fromeach one of the cells simultaneously.
Okay.
So now you've made allof our listeners excited.
You have.
You've touched on why we are leading.
We're providing thesedifferentiated solutions.
(11:02):
You've talked about this reference design.
It sounds great.
It has everything they need.
If you want to get your solutiondone faster, this reference
design's gonna get you there.
So I have to ask (11:11):
How do they get the design?
You've gone through what'sincluded, but what are the
steps for them to get started?
So to get started with thereference design, they can just
go to our website right now.
If they go under Power Energy, and EnergyStorage, they'll find the BESS 1500
volts, and that is our reference design.
(11:31):
They can look into the information,download the documents, they can
look into the schematics, theycan look into the board layouts.
They can even take a peek at someof the functional safety documents.
The entire source code for thesoftware is also available.
It's downloadable from our websitewithout even having to register.
(11:53):
If they want to purchaseone of these kits, they just
can click on the buy button.
The cost is around $2,500 and theyget the entire kit for evaluation.
So for those listening, it soundslike they just need to go to
NXP.com/BESS to get started.
Correct.
All right.
(12:13):
Well, Marcelo, this has been great.
Before we wrap up, maybe you couldspend a little time going through
the technical block diagram.
You said you had it out infront of you, so that'll help.
Talk about some of the features of theblock diagram and for our listeners,
maybe drop a couple NXP componentsthat they may recognize that are
included in the reference design.
(12:34):
Sure.
So let me step back a little bit and tellyou what this reference design is made of?
Basically we have threehardware components.
These three hardware componentsare three different PCBs.
One of them is the BMU, thatstands for Battery Management Unit.
And this is the brain of the system.
It monitors the overall battery pack.
(12:55):
It manages the communication.
Ensures that everythingoperate in a safe manner.
And that's where we implement the keyfeatures like functional safety, static
charge estimation, and thermal management.
In this PCB, you find one of ourmicrocontrollers, so that's an S32K358.
That is a three core device,two cores in lockstep.
(13:17):
One core is for the application layer.
We have the PMIC.
We have CAN FD interface.
We have Modbus interface from NXP.
We also have TPL Gateway.
That is for the isolated communicationbetween the BMU and the High
Voltage pieces of the system.
We have contactor drivers, and SecureElement for the Battery Passport.
(13:39):
So these are the componentswithin this BMU component.
The other component is the BJB, andthat stands for a Battery Junction Box.
And this is a high voltage monitoringsystem and current sensing.
So it looks into high voltage protection,pre-charge control, manages all the
contactors, does isolation monitoring,fault detection, and most importantly is
(14:03):
the current measurement through the shunt.
In that piece, we have the MC33772,which is our Analog Front End,
which is optimized for this currentmeasurement for the high voltage system.
And then lastly, we have ourCMU or Cell Monitoring Unit.
That is what monitors individualcells and their temperatures.
(14:25):
It's where you implement passivebalancing or the active balancing and EIS.
In this block we have the MC33774,which is the 18 channel Analog Front
End with the highest precision forindustrial components on the market.
I just wanna make sure that weare evolving this and so on the
next generation, we're movingto our BMI7318, which is a SIL-2
(14:49):
certified Analog Front End thathas 25 year of guaranteed lifetime.
That's critical for Energy Storage.
We know that most customers outthere, they want the systems
to last beyond 20 years.
So we are designing our componentsto last for minimum 25 years.
(15:10):
Oh, that's excellent.
That's a very good walkthrough ofthe block diagrams, and Marcelo I'll
capture those key blocks in the episodenotes and maybe put some key links
so people can reference those andget directly to the reference design
that you and Bridgette called out.
Good.
I just wanna mention one more thing.
Sure.
This reference design and thissystem is very flexible and modular.
(15:34):
So it doesn't matter if you're buildinga 48 volt system or a 1500 volts system.
It's capable and scalable.
Okay?
We've certified this for upto 1500 volts and 500 amps.
All right.
Well is there any otherinformation that you'd like to
share with the listeners Marcelo?
No.
If they need more information they canfind all the documents in our website.
(15:58):
We also have a lot of videos.
We are gonna beparticipating on many events.
So CS, the smarter E in Europe, and RE+.
I'm gonna be there as wellfor those who are attending.
And yes I think this is it.
All right, well make sure you stop byat those events and say Hi to Marcelo.
And again, appreciate that youtook the time today to share
(16:21):
a lot of this information thatI had not even heard about.
This is great.
Let's start our recap, Bridgette.
Today, with the help of Marcelo, I'velearned quite a bit about Energy Storage.
We've learned what the trends are,what's redefining the space, and
how NXP is providing not just thosesilicon components that Marcelo listed,
(16:43):
but really that full stack solution.
Everything from the Software, theSafety, the Certifications, and
real world reference designs thatcan be scaled to fit their power
and application requirements.
So developers that are workingon the next generation of Energy
Systems know where they can go.
They can come to NXP.
(17:04):
And for those ready to exploremore, we will drop the links in
the show notes for the videos,documentation, the reference designs.
And while you're there, be sure to like,subscribe and turn on notifications
so you never miss an episode.
And Marcelo, thanks so muchfor being here with us today.
We really appreciate it.
Thank you for having me.
(17:24):
All right.
And until next time, stay energized,charge your batteries, keep
innovating, and we'll see you onthe next EdgeVerse Techcast episode.

Correct.
All right.
(12:13):

That is a three core device,two cores in lockstep.
(13:17):
One core is for the application layer.
We have the PMIC.
We have CAN FD interface.
We have Modbus interface from NXP.
We also have TPL Gateway.
That is for the isolated communicationbetween the BMU and the High
Voltage pieces of the system.
We have contactor drivers, and SecureElement for the Battery Passport.
(13:39):
So these are the componentswithin this BMU component.
The other component is the BJB, andthat stands for a Battery Junction Box.
And this is a high voltage monitoringsystem and current sensing.
So it looks into high voltage protection,pre-charge control, manages all the
contactors, does isolation monitoring,fault detection, and most importantly is
(14:03):
the current measurement through the shunt.
In that piece, we have the MC33772,which is our Analog Front End,
which is optimized for this currentmeasurement for the high voltage system.
And then lastly, we have ourCMU or Cell Monitoring Unit.
That is what monitors individualcells and their temperatures.
(14:25):
It's where you implement passivebalancing or the active balancing and EIS.
In this block we have the MC33774,which is the 18 channel Analog Front
End with the highest precision forindustrial components on the market.
I just wanna make sure that weare evolving this and so on the
next generation, we're movingto our BMI7318, which is a SIL-2
(14:49):
certified Analog Front End thathas 25 year of guaranteed lifetime.
That's critical for Energy Storage.
We know that most customers outthere, they want the systems
to last beyond 20 years.
So we are designing our componentsto last for minimum 25 years.
(15:10):
Oh, that's excellent.
That's a very good walkthrough ofthe block diagrams, and Marcelo I'll
capture those key blocks in the episodenotes and maybe put some key links
so people can reference those andget directly to the reference design
that you and Bridgette called out.
Good.
I just wanna mention one more thing.
Sure.
This reference design and thissystem is very flexible and modular.
(15:34):
So it doesn't matter if you're buildinga 48 volt system or a 1500 volts system.
It's capable and scalable.
Okay?
We've certified this for upto 1500 volts and 500 amps.
All right.
Well is there any otherinformation that you'd like to
share with the listeners Marcelo?
No.
If they need more information they canfind all the documents in our website.
(15:58):
We also have a lot of videos.
We are gonna beparticipating on many events.
So CS, the smarter E in Europe, and RE+.
I'm gonna be there as wellfor those who are attending.
And yes I think this is it.
All right, well make sure you stop byat those events and say Hi to Marcelo.
And again, appreciate that youtook the time today to share
(16:21):
a lot of this information thatI had not even heard about.
This is great.
Let's start our recap, Bridgette.
Today, with the help of Marcelo, I'velearned quite a bit about Energy Storage.
We've learned what the trends are,what's redefining the space, and
how NXP is providing not just thosesilicon components that Marcelo listed,
(16:43):
but really that full stack solution.
Everything from the Software, theSafety, the Certifications, and
real world reference designs thatcan be scaled to fit their power
and application requirements.
So developers that are workingon the next generation of Energy
Systems know where they can go.
They can come to NXP.
(17:04):
And for those ready to exploremore, we will drop the links in
the show notes for the videos,documentation, the reference designs.
And while you're there, be sure to like,subscribe and turn on notifications
so you never miss an episode.
And Marcelo, thanks so muchfor being here with us today.
We really appreciate it.
Thank you for having me.
(17:24):
All right.
And until next time, stay energized,charge your batteries, keep
innovating, and we'll see you onthe next EdgeVerse Techcast episode.
