Best of LinkedIn: Electrification & Battery Technology CW 28/ 29

00:00:00: Provided by Thomas Allgaier and Frennis, based on the most relevant LinkedIn posts about electrification and battery technology in calendar weeks twenty-eight and twenty nine.

00:00:09: Frenness is a B to be market research company that supports automotive suppliers with building feature by future competitive intelligence.

00:00:17: That shows exactly how their product stacks up against the competition.

00:00:21: you can find more info In the description.

00:00:23: all right look at it.

00:00:24: Yeah, so imagine you're buying a million dollar sleet of electric trucks for your logistics company.

00:00:31: I mean the vehicles are shiny The drivers are trained Your routing software is completely primed.

00:00:36: Sounds great So far Right.

00:00:38: But then You discover that the local power company Legally will not let you plug them into the grid For another twenty four

00:00:45: months.

00:00:45: Oh wow yeah That's a nightmare.

00:00:47: It's

00:00:47: specific Nightmare that quietly choking the entire EV transition.

00:00:51: right now We're looking at a stack of industry insights today that completely shatters the illusion.

00:00:56: That electrification is just about, you know building enough cars and bolting enough charges to the pavement.

00:01:01: The narrative has fundamentally shifted.

00:01:03: the vehicles are here so the question now Is what breaks next as this massive adoption scales up

00:01:10: right?

00:01:10: And the physical constraint emerging in the background Here is the grid itself.

00:01:14: we were seeing these incredible exponential gains in global EV sales battery manufacturing,

00:01:22: which is great news.

00:01:22: Obviously

00:01:23: it is.

00:01:24: but as with any exponential technology curve when it hits the physical world The bottleneck moves.

00:01:30: It has moved from the assembly line directly to the copper wires buried under our streets.

00:01:35: that copper wire Yeah?

00:01:36: The binding constraint for the next decade of mobility isn't automotive engineering.

00:01:41: its well Its civil engineering and localized power distribution.

00:01:45: I mean, we have all these companies advertising these lightning fast four hundred kilowatt charging experiences.

00:01:51: Yet the infrastructure beneath it seems to be just groaning under the weight

00:01:55: Totally groaning.

00:01:56: Sarah Ellis and Rachel Lye both pointed this out in their recent posts, they're tracking charging projects across Europe And the primary source of delay isn't a lack of physical charging hardware rolling out of factories.

00:02:06: No it's not the hardware at all.

00:02:08: The bottleneck is the grid connection limit.

00:02:10: Yeah It is the agonizingly long wait time to actually get the necessary electricity capacity routed into specific site.

00:02:18: We are talking about grid operators needing to lay new high voltage cables, upgrade substations and you know install these massive transformers.

00:02:26: And

00:02:26: those take forever right?

00:02:28: Exactly!

00:02:28: Those transformers alone can have a lead time of twelve or twenty four months... ...and that's assuming even navigate the local permitting process easily.

00:02:36: Wow So you have operators with pallets of ultra-fast chargers ready to deploy, but the local utilities simply cannot deliver the megawatts required

00:02:55: dial-up internet cable.

00:02:56: That is a perfect analogy!

00:02:57: You can have the most advanced piece of routing technology sitting in your living room, but if the pipe feeding it from the street is tiny you are going to be buffering...the bottleneck is connection not tech.

00:03:08: The pipe metaphor is highly accurate and the volume data or electricity trying to push through those pipes is about to scale exponentially.

00:03:18: Christophe LePhilibert shared some data from PWC Strategy &'s that contextualizes this perfectly.

00:03:26: They project that EV charting demand in Europe will hit around two hundred terawatt hours by twenty thirty five,

00:03:32: okay?

00:03:33: Let's let's scale that number for a second because two hundred per hour is completely abstract very

00:03:38: abstract.

00:03:38: yeah.

00:03:38: That is roughly equivalent to the entire annual electricity consumption of a country like

00:03:43: Spain.

00:03:43: It's wild I think about.

00:03:44: we're essentially talking about plugging a medium-sized industrialized nation into the existing European grid purely to move vehicles around.

00:03:52: Which means the fundamental business model for charge point operators, you know?

00:03:56: The CPO is running these networks.

00:03:58: it has to shift.

00:03:59: It's no longer just a land grab of merely installing hardware in good locations Right!

00:04:03: Its getting more complicated

00:04:05: Much More.

00:04:11: They have to decide algorithmically where every available kilowatt goes across a network, To avoid triggering massive peak demand charges from the utility companies.

00:04:20: Or worse browning out of local neighborhood.

00:04:22: But if the overarching goal is intelligent orchestration to save The grid how does that actually play out for the person sitting in the driver seat?

00:04:31: That is the million-dollar question.

00:04:33: Because if I pull up to a charger advertising high speeds, i don't really care about the operator's load balancing algorithms...I just want the electrons in my car so that they can leave you know?

00:04:42: Right and this exact friction point!

00:04:45: The macro need for orchestration directly collides with micro experience of the driver.

00:04:50: If site fails during peak demand, it suffers regardless of how smart the back-end software is.

00:04:56: Yeah!

00:04:57: Felix Hammer posted a live review from an IONITY charging site in Girona, Spain right at the peak of summer.

00:05:02: travel demand.

00:05:03: Oh...I saw this one.

00:05:04: He was facing a twenty minute queue just to get plug Overflowing garbage bins and thirty four degree heat And zero shade.

00:05:11: The wheat times are one thing but power output he noted Was real red flag there.

00:05:16: Exactly!

00:05:17: The physical units that station were promising four hundred kilowatts But they were maxing out at just a hundred kilowatts.

00:05:24: A quarter of the promise speed?

00:05:25: Yeah,

00:05:26: The local grid simply couldn't handle the aggregate pull Of all those vehicles charging simultaneously.

00:05:32: So the site controller aggressively throttled the sessions to prevent a collapse.

00:05:36: so the hardware was functioning perfectly.

00:05:38: technically

00:05:39: Technically yes!

00:05:40: The machine says four-hundred, the grid says one hundred and the driver is the ones stuck waiting in heat for Four times longer than expected.

00:05:48: Okay if transformers take two years to install and public fast chargers are throttling customers to protect the grid, something has to give.

00:05:56: I mean you can't just hit pause on the transition to electric mobility while utility companies dig up the

00:06:01: streets.".

00:06:01: No!

00:06:01: You definitely can't...

00:06:03: How our engineers cheating the grid here?

00:06:05: Like how do you bypass a constraint that is so

00:06:08: physical?!

00:06:09: You basically change the mathematical shape of how you draw power.

00:06:11: Okay what does it mean?

00:06:12: Well if you cant pull massive spike energy all at once…you pull tiny amount continuously.

00:06:18: Oh

00:06:18: right Muhammad Taha highlighted this exact mechanism.

00:06:23: He was observing a new wave of battery-integrated DC chargers from companies like Huawei, Sungro and BYD.

00:06:33: Yes those are super interesting.

00:06:35: Yeah instead of demanding a three hundred fifty kilowatt surge From the grid The moment a car plugs in These units have A massive stationary lithium ion Battery built directly into the cabinet itself.

00:06:46: Right they utilize a concept called peak shaving So the chargers connect to the grid with a very small standard connection, maybe pulling just forty or fifty kilowatts.

00:06:54: It's like normal commercial connections?

00:06:56: Exactly!

00:06:57: And it trickle charges its own internal battery all day and all night.

00:07:00: Yeah

00:07:01: To the utility company...it looks like a modest highly predictable steady draw of power.

00:07:06: But when an EV pulls up The charger doesn't ask for more power.

00:07:09: It just dumps energy stored in its internal battery into car at ultra-fast speeds.

00:07:14: The grid is completely insulated from the spike.

00:07:16: The car gets its three hundred and fifty kilowatt charge, And you bypass the need for a million dollar grid upgrade.

00:07:23: It's really elegant work around

00:07:25: it Really is!

00:07:26: By the way if You want to keep catching these kinds of deep structural shifts in the industry before they become mainstream news?

00:07:46: Commercial fleets are tackling this constraint from a completely different angle.

00:07:50: They're looking at their operational schedules and realizing they might not need fast charging it all.

00:07:54: Oh, really?

00:07:55: Yeah

00:07:55: Sebastian Hensler shared an analysis of a brewery depot in Freistat.

00:07:59: There were on the fleet have heavy electric trucks And instead buying those massive three hundred kilowatt fast chargers which again require those two-year transformer upgrades The charge to trucks overnight at a mere forty kilowatts per vehicle for twelve hours.

00:08:15: Ah, so just matching the physics of the charge to reality down time.

00:08:19: Just a slow steady sip of electricity

00:08:22: Exactly

00:08:23: And I imagine that economics are vastly superior.

00:08:27: Oh!

00:08:27: The economics have totally transformed.

00:08:29: You avoid massive capital expenditure of high-voltage equipment.

00:08:33: you avoid utility peak demand tariffs and crucially significantly extend the life span of vehicles.

00:08:40: battery

00:08:41: Because slow charging generates far less heat.

00:08:44: Less

00:08:44: heat and less degradation, yeah If you know exactly when your trucks are sitting idle, You do not need to over-engineer your facility.

00:08:51: Okay

00:08:52: that makes total sense for a regional brewery That parks its fleet every night.

00:08:56: But what about long haul logistics?

00:08:58: What about operators where uptime is the only metric that matters and A truck's sitting idle For twelve hours just destroys their margins?

00:09:07: Right if they're actively avoiding megawatt grid connections Because of infrastructure bottlenecks we talked How are they keeping trucks on the road?

00:09:15: Are they doing battery

00:09:15: swapping?".

00:09:16: Yes, exactly.

00:09:18: They're decoupling the batteries from their vehicle entirely.

00:09:21: Marcus Ennichern and Todorov brought up a joint venture called Swaptopus.

00:09:28: It's a partnership between the battery giant CETL and Octopus Energy.

00:09:33: They build over thirty battery-swapping hubs for electric trucks across Europe by twenty thirty five.

00:09:40: So instead of plugging the truck in and waiting, you drive into a bay.

00:09:44: A robotic system drops your depleted five hundred kilowatt-hour battery inserts a fully charged one And you drive away in like five minutes.

00:09:51: yep Five minutes and structurally it alters The entire financial model of trucking.

00:09:56: how

00:09:56: so?

00:09:56: Well, it shifts the battery costs from a capital expenditure where you're buying the hugely expensive battery up front with truck chassis to an operating expenditure.

00:10:04: Oh interesting!

00:10:05: You essentially lease energy and degradation as you go.

00:10:07: The fleet owner doesn't worry about battery lifespan anymore because they don't own the battery.

00:10:11: Swapping

00:10:12: always sounds incredibly complex mechanically though I mean.

00:10:15: do we actually have evidence that this works at commercial scale or is just pilot program generating press releases?

00:10:20: No It's operating its scale.

00:10:22: today Khadza Ivinson-Sognifer reported that NIO just passed three hundred thousand battery swaps across Europe for their passenger cars.

00:10:30: Three hundred thousand?

00:10:32: Yeah,

00:10:32: each swap takes about three minutes they calculate.

00:10:35: They've given millions of minutes of dwell time back to drivers compared to traditional fast charging.

00:10:40: That's

00:10:40: massive and while the hardware engineers are building robotic swap stations to save time The software engineers or you know finding efficiencies on the backend right.

00:10:49: Kasper H. Rasmussen shared a fascinating look at how his team is optimizing the maintenance of these massive networks.

00:10:55: They used small purpose trained AI model to diagnose EV charge fault data.

00:11:01: I love this example.

00:11:02: This is perfect for moving away from brute force solutions.

00:11:05: Instead of routing all their diagnostic data through massive expensive frontier AI models like GPT-IV, they trained tiny specialized models just one job

00:11:16: which was just reading the telemetry data from a failed charging session and explaining what physical component broke.

00:11:22: The efficiency gains there are wild.

00:11:25: Rasmussen noted, this small model outperformed ran twice as fast, and was a hundred fifty times cheaper to operate.

00:11:35: A hundred fifty time cheaper?

00:11:36: Yeah!

00:11:37: They analyzed one point five million charging sessions for about a thousand dollars.

00:11:42: running that same volume through general-purpose frontier model would have cost up to six hundred thousand dollar.

00:11:47: That's an insane cost difference.

00:11:49: It proves

00:11:50: this industry scales.

00:11:51: you don't need the biggest hammer You Need The Most Precise

00:11:54: Tool Definitely, and you know.

00:11:56: if the industry is successfully finding ways to detach batteries from trucks To keep them moving.

00:12:01: And using highly targeted software to manage the networks The logical next step Is to look at the biggest underutilized asset in the entire ecosystem We do!

00:12:09: The maximum amount of energy sitting In passenger cars parked in driveways and office lots.

00:12:13: Right Because we have historically treated the EV purely as a consumer of electricity, A one-way street.

00:12:20: The power plant generates it, the grid transmits it...the car absorbs it.

00:12:24: But an EV is fundamentally just massive lithium ion battery on wheels.

00:12:29: Thomas Becker and Dr.

00:12:31: Jens Berger detailed the BMW Group's Gen-Six eDrive technology, their commercial rollout of vehicle to grid or VTG in partnership with EON in Germany.

00:12:42: The

00:12:43: concept transforms millions of isolated car batteries into a distributed flexible storage network for the national grid.

00:12:50: Walk

00:12:50: me through the mechanics like how does my parked car actually help the grid?

00:12:54: Sure so.

00:12:55: an EV equipped draws power when energy is abundant and chief, say during the middle of day.

00:13:01: When solar panels are overproducing it stores that cheap energy.

00:13:04: right then when demand spikes in the early evening And the grid is strained The car feeds that stored energy back into the house or back to the grid selling at a premium

00:13:13: I see if

00:13:14: flattens the demand curve and turns the vehicle from a passive consumer Into an active contributor to a stable energy system.

00:13:20: Okay?

00:13:22: Oh,

00:13:26: absolutely.

00:13:27: It is the ultimate utopian concept!

00:13:29: Why should an automotive supplier or a fleet operator believe this moving from powerpoint presentation into physical reality right now?

00:13:36: Well I mean you answered your own question earlier with regulatory updates.

00:13:39: Alright…

00:13:40: The standards are finally catching up.

00:13:41: Yes

00:13:42: because without universal language for these devices to speak each other V-to-G was impossible.

00:13:47: Jack Berger and Christian Ponsiers de Brouwer pointed out critical breakthrough which is publication of ISO one four one eighteen twenty amendment.

00:13:56: This is the protocol that formally standardizes AC bi-directional charging.

00:14:00: Precisely, it's basically a digital handshake.

00:14:03: before any electricity flows backward –the car and grid have to negotiate.

00:14:07: They need talk with each other!

00:14:08: Right….

00:14:09: The car has securely transmit its current state of charge, driver required departure time & price threshold at which the drivers willing sell power.

00:14:18: ISO One February, one eighteen twenty provides the universal protocol for that negotiation.

00:14:24: regardless of whether you are driving a BMW afford or a Hyundai and regardless who built the charger.

00:14:29: And this standard is dropping right ahead of EU's twenty-twenty seven mandate which requires new charging infrastructure to technically support bidirectional functions.

00:14:38: Exactly.

00:14:39: Regulators are officially recognizing that since cars sit parked ninety-five percent of the time, they're legally and technically demand flexibility assets.

00:14:48: The market signals are finally aligning with engineering.

00:14:51: They ARE!

00:14:52: But this is a big... but that digital handshake introduces vulnerability.

00:14:56: that industry just waking up too Uh-oh.

00:14:58: Yeah, when millions of cars start negotiating with the grid and pushing energy back and forth The charging port on the front of the vehicle ceases to be just a physical plug.

00:15:07: It becomes the critical network entry point into the national power grid.

00:15:11: Marcelle Ricksen shared a post about a disclosed vulnerability known as CVE.

00:15:15: twenty twenty six nine zero three nine.

00:15:18: That highlights exactly how fragile this new entry point is.

00:15:21: right.

00:15:22: Researchers discovered that certain commercial chargers were shipping with default root credentials on the vehicle-facing interface.

00:15:28: The username was literally Root and password was Root.

00:15:31: I mean, why does a charging cable even have a login prompt?

00:15:34: That's crazy!

00:15:35: Well, manufacturers often leave these backdoor access points open so maintenance technicians can easily run diagnostics or reboot a charger if software hangs...

00:15:43: Okay…I guess it makes sense.

00:15:45: But leaving those credentials active in physical pins connect to car is massive oversight.

00:15:50: The researchers used an EV simulator board, which is basically a device that mimics a car's communication protocols plugged it into the charger and bypassed the security entirely.

00:16:00: That completely flips the cybersecurity model on its head!

00:16:04: You aren't hacking a firewall in a server farm.

00:16:07: you are hacking a piece of plastic sitting at grocery store parking lot.

00:16:10: Exactly

00:16:11: If a bad actor can spoof that maintenance handshake across thousands of V-to-G enabled chargers simultaneously, they could command all those vehicles to dump their energy or stop charging at once.

00:16:22: It's terrifying!

00:16:23: It creates a distributed physical cybersecurity risk capable of triggering localized grid failures.

00:16:29: We have to start treating the plug as dumb conduit for electricity and start treating it as vital network boundary

00:16:35: Very well said.

00:16:37: And as vehicles become grid nodes and charging networks becomes critical national infrastructure, the batteries themselves are under intense scrutiny.

00:16:46: Whether we're talking about V-to-G networks, megawatt truck chargers or passenger cars... Every single one of these batteries has to be manufactured, tracked & regulated

00:16:56: Which brings us into the geography of supply chain.

00:16:58: It is shifting in ways that completely defy common expectations.

00:17:03: Daniel Czerznowski shares a statistic that catches almost everyone off-guard.

00:17:07: I was surprised by this one!

00:17:08: Yeah, if you ask where Europe's EV batteries are manufactured the assumption is usually Germany or maybe Scandinavia but it's Poland.

00:17:17: Poland

00:17:17: is currently world second largest producer of lithium ion batteries

00:17:21: and It is anchored by a staggering amount of concentrated manufacturing.

00:17:25: The LG Energy Solution Gigafactory in Roka covers a hundred hectares, employs nearly ten thousand people and outputs eighty-six gigawatt hours annually.

00:17:35: To put that into perspective... That is enough capacity to power over a million long range EVs every single year!

00:17:42: That one facility supplies roughly sixty percent of Europe's entire EV battery demand And it alone contributes around three percent of Poland's national GDP.

00:17:51: The sheer industrial scale required to feed this transition is breathtaking.

00:17:56: It's massive physical production, but the looming hurdle for all of these.

00:18:00: manufacturing isn't just securing lithium or scaling factory lines – it's the incoming wave of compliance!

00:18:06: Oh…the bureaucracy?

00:18:07: Exactly.

00:18:08: Rosana Bolina and Dimon Jameekic brought up the impending reality.

00:18:13: Starting in February, the EU is mandating that every industrial and EV battery have a digital identity access via QR code.

00:18:21: And this passport requires tracking approximately eighty different data points per battery.

00:18:25: It covers entire life cycle from carbon intensity of smelting process to exact origin of cobalt to percentage of recycled nickel and even mandatory child labor compliance audits down supply chain.

00:18:37: I mean how does an emerging European battery start up actually execute?

00:18:41: Hiring software engineers to build APIs that connect to auditing software in a mining operation on another continent is massive barrier entry.

00:18:49: It's huge!

00:18:50: Does slapping eighty data points of compliance burden onto battery actually help Europe build competitive industry?

00:18:57: Or does it just front load, massive fixed costs for new entrants before they can even reach commercial volume?

00:19:03: That the structural debate right now Because while Europe has focused regulation China is focused on execution.

00:19:10: Merlin Frank shared data showing that China currently drives roughly sixty percent of global EV battery demand, whereas Europe is sitting at about twenty percent.

00:19:18: Wow!

00:19:19: China achieved massive economies of scale first and then began regulating.

00:19:24: Furthermore, China's own digital tracking system for batteries already went live in April.

00:19:28: twenty-twenty six almost a full year ahead the European mandate.

00:19:31: So if China dominates the raw volume and beat Europe to market on the tracking software, how does a European supplier compete?

00:19:38: Are they regulating themselves out of the race.

00:19:40: Well, Europe cannot compete with China on pure economies of scale or cheap raw material extraction right now.

00:19:47: but Europe might compete differently by owning.

00:19:53: Julian Renpenning highlighted a startup called Voltfang that provides the perfect example of this strategic pivot.

00:20:00: Right, they are building an entire business model out of second-life EV batteries.

00:20:04: Exactly A lithium ion battery degrades over time.

00:20:07: when it drops to about seventy or eighty percent its original capacity.

00:20:11: It's no longer useful for accelerating two ton vehicle But is perfectly fine for stationary storage.

00:20:17: Sure Voltfang pulls these degraded batteries runs advanced diagnostics to test their internal health, and repurposes them into commercial storage infrastructure.

00:20:27: They are taking something the automotive industry considers waste... ...and turning it into grid infrastructure.

00:20:32: It's brilliant because it completely bypasses the raw material bottleneck.

00:20:36: Exactly no new mining required.

00:20:38: You don't need to mine new lithium if you can just intercept the degraded batteries coming out of cars.

00:20:44: Voltfang started in a basement and is now a two hundred fifty million euro infrastructure business backed by institutional capital.

00:20:52: If Europe can't outmine or outmanufacture the competition, building an ecosystem where the battery lives three different lives before it ever hits a recycling shredder that could be a massive domestic

00:21:03: advantage.".

00:21:04: The overarching reality connecting all these sources is at the era of simply manufacturing electric vehicles.

00:21:10: as over we are now in Every vehicle rolling off an assembly line is no longer just a mode of transport.

00:21:18: It's becoming a highly complex node in the shifting fragile energy network.

00:21:22: and as those vehicles transform into active grid nodes, And as bi-directional charging scales up to balance our energy needs The power dynamics of the industry are going to invert.

00:21:31: how

00:21:31: so well?

00:21:31: Well the ultimate broker of energy In the future might not be the traditional utility companies generating the power.

00:21:37: it might Just be the software companies that manage aggregate and orchestrate the electricity flowing across millions pathways and parking lots.

00:21:44: That's a profound shift,

00:21:45: right?

00:21:46: The company is writing the code will control the grid.

00:21:48: it's a lot to think about.
