The Temperature of Production Inside 슬롯 777 EVS’s Private Booth

At CES 2026, what impressed me most at the BH EVS booth was not the language of “we can,” but “we are doing.” Their in-vehicle wireless charging is not a convenience feature - it is an automotive electronics module where power, data, certification, and software updates operate as one system, and production is proven only through timing and quality. That production DNA is now expanding into radar, heating, BMS, EV charging, and robotic charging. On site, I witnessed the direction of BH EVS’s “operational automotive electronics” taking shape in real time.

“Vice President Park (JinSup Park, Head of R&D), please walk us through it.”
슬롯 777 EVS CEO Jinyong Kim said.
CES 2026. The invitation to BH EVS’s private booth was not a simple “visit.” The CEO greeted us first - then the team began explaining each product line, one after another. When an introduction ended, questions followed. When the questions ended, the next product came in. And then came more questions. That rhythm continued for a full hour.
Normally, after that long, either the speaker or the audience starts losing focus. But here, it was the opposite. The deeper the session went, the sharper the details became - and the more often you found yourself thinking, “That’s exactly it.” Above all, the tone of their answers was different. It wasn’t “we can,” it was “we are.”
For example, when the topic was in-vehicle wireless charging, the conversation didn’t start with how well it charges. It started with how they close the exact gaps customers demand, and how they convert that demand into something deliverable. In other words, BH EVS was treating wireless charging not as a single feature, but as a production-grade system where power, data, certification, and updates are connected inside the vehicle. And that operational logic extended naturally into radar, sensors, heating, battery management systems (BMS), EV charging, and robotic charging.



Act 1: Wireless Charging as the Starting Point - The Core Is “Operational Electronics”

BH EVS’s strongest foundation is automotive wireless charging. This business began in 2014 inside LG Electronics’ VS (Vehicle Solution) Division, and after the transition and acquisition process in 2022, it merged with the BH Group and expanded into its current form. Vice President JinSup Park led the business at LG and explained that around 60 members joined BH and continued the customer development and production process without interruption.
Today, 슬롯 777 EVS operates a mass production system of 6 - 7 million units per year, and the volume is expected to exceed 10 million units in the future. Its customer base has also expanded to 12 global OEMs.
But BH EVS does not treat wireless charging as a mere “convenience feature.” In-vehicle wireless charging is an automotive electronics module that comes with MCU, NFC, network integration, cybersecurity, and functional safety requirements - and it must continue to evolve even after SOP through software updates and certification 대응, driven by the fast-changing mobile ecosystem.
“Charging is only 50% of automotive wireless charging. The other 50% is NFC, network, security, and updates,” said Vice President Kyungyoon Kim.
That sentence was close to a definition of the entire booth. The moment wireless charging connects to the in-vehicle network, it stops being a “power device” and becomes a system that includes authentication and operations. NFC-based digital key linkage, post-connection updates, and cybersecurity requirements all rise together. Secure Boot, key management, encrypted messaging, and integrity management become part of the product. And because the smartphone ecosystem changes rapidly, this is something the supplier must keep matching even after mass production begins. BH EVS was viewing wireless charging not as a power component, but as an “operational product” that includes OTA continuity.

Standards Are Not Something You “Follow” - They Must Be Finished Before They Arrive

At the booth, the recurring keyword was not “speed,” but “timing.” The message was clear: if you move after standards are finalized, you are already late. Wireless charging standards shift constantly as device makers, chip vendors, certification bodies, and OEM requirements collide. In the end, product development is not simply about laying out circuits - it is about moving through the rhythm of standardization → certification → adoption → mass production.
Here, BH EVS emphasized its differentiation: an in-house solution. While many competitors build products by combining chip vendor reference designs and software, BH EVS takes a different approach - running its own software stack on a general-purpose MCU. The meaning is not “we built it ourselves,” but the practical outcome: faster response to field issues, and faster certification rollout.
“We don’t 그대로 use the chip vendor solution. We run our own software on a general-purpose MCU. That’s why development and certification are faster,” said Vice President Kim.
And that matters because every expansion shown later in the booth followed the same logic. Becoming a real product means having a structure that can keep up when requirements change - and that structure comes from owning the design and software.

The higher the power, the more thermal design determines the product’s fate (left). In-cabin charging becomes an “operational system” the moment charging and data (display/mirroring) converge into one interface. When USB-C carries both charging and video output, the port becomes a UX gateway - not an accessory.



Smaller, More Integrated, and Built Around Heat
How wireless charging reaches 슬롯 777

One of the first things that stood out was BH EVS’s next-generation wireless charging concept based on an ultra-compact package. In vehicles, packaging space is fixed - and once a vehicle program is locked, structural changes are hard. So “miniaturization” is not a pure size competition; it is an application strategy that increases the number of possible installation locations.
The “Ultra Compact” concept integrates not only circuitry, but also active cooling (fan), an NFC antenna, and digital key scenarios inside a small package. NFC is not just authentication - it also supports logic that prevents issues caused by real-world behavior, such as having cards inserted together with the phone. In a vehicle, such small behaviors quickly become quality issues.
The final barrier that never disappears is heat. In high-power charging, heat is not just discomfort - it becomes performance limitation, durability risk, and safety risk. BH EVS emphasized efficiency advantages enabled by coil alignment structures. By reducing coil distance, they raise efficiency and embed high-power roadmaps into real product architectures. The key point was not “talking about the future,” but pushing design forward based on the reality of heat.

For an Idea to Become Production, You Need OEM “Back-and-Forth”

The booth also showed how technology gets convinced - and connected to 슬롯 777. One of the hardest problems in wireless charging is thermal management, especially surface temperature control, which can decide the fate of the product.
BH EVS presented an approach based on a thermoelectric element (Peltier). But again, the key was not “we used Peltier” - it was that the idea became real through the process: PoC → feedback → improvement → production, together with the OEM.
“We didn’t think fan cooling alone was enough. So we proposed Peltier and did a PoC. The results were good, and we moved into the production stage.”
Vice President Kim described the cycle simply: “We keep visiting, keep contacting, get feedback, improve it, and bring it back again.” What a supplier needs is not a single pitch, but the development and quality stamina to survive that repetition. What BH EVS demonstrated was not a technology showcase - it was production endurance.


  Act 2: The 3-Pillar Declaration Came “Right Before Radar”
When the expansion sequence changes, the temperature shifts

The most striking turning point was that the sensor demo was not presented as a simple “new product introduction,” but came immediately after BH EVS explained its expansion strategy. In other words, radar was not a new toy - it appeared as one of the axes BH EVS must secure to move into the next phase.
“We’re preparing three major pillars,” CEO Jinyong Kim said.
“First is smart sensors and smart actuators. Radar included - AI-enabled smart sensors will be one pillar. Second is robotics. If we go into robot charging and humanoids, we’ll need component expansion such as FPCB parts for joints. Third is electrification - BMS, and charging.”
And then, the radar demo started right away.
The feeling was clear: this was not a vision that ends as words. It was immediately linked to real hardware and demonstration. That linkage suggests 슬롯 777 EVS is not expanding by listing items, but designing expansion through market timing and production rhythm.

Sensors & Radar: Regulation Timing Creates the Product Market

The first pillar is smart sensors and smart actuators. The trend of Euro NCAP including CPD (Child Presence Detection) as a scoring item can significantly push sensor demand upward. 슬롯 777 EVS is already in discussion with customers before the requirement becomes mainstream.
The demo was immediate and visual. When the view was blocked with a blanket, the camera detection stopped. But the radar recovered the detection signal after a certain time. It was a clear scene showing the advantage of radar under real-world “occlusion” conditions.
Another radar concept was a short-range radar designed to reduce collision risk by detecting approaching objects (bikes, kickboards, etc.) when opening doors. It emphasized a wide FOV (around 160 degrees) and fast detection response, and clearly highlighted advantages over ultrasonic sensing. The message here was simple: sensors are not defined by demos - markets are defined by regulation and 슬롯 777.



Solving EV Heating Through “Film, Materials, and Manufacturing”

One unexpectedly powerful demo was a heating film-based heater solution introduced by Engineer Jun Lee. EV range drops significantly in winter, and one of the reasons is heating efficiency. PTC heaters create efficiency 부담 and dry air is also disadvantaged in emotional quality. 슬롯 777 EVS approached this challenge with a heating film solution.
It was presented as a method that can selectively implement radiant heat and conductive heat. When you bring your hand closer, you can feel gentle radiant warmth; when you reduce the setting, it behaves more like traditional seat heating through conduction. A safety “touch-off” function was included as well. Applications were open across floor mats, armrests, and insertion into plastic structures.
The reason this solution was interesting was not the idea itself, but how it connects to BH Group’s material and manufacturing strengths. The material structure - PI film, CNT paste, silver paste - aligns with BH’s FPCB-based capabilities. From raw material purchasing to film production, controller production, and interface integration, the system is integrated end-to-end. This heater was not a single product - it was an expansion of production DNA by packaging materials, manufacturing, and quality into one stack.

In EV charging, what matters is not the idea, but packaging and thermal design that survive underbody conditions - this is not an exhibit, but a production-ready module.



In Charging, “Auto-Wired” Opens Before the “Wireless Future”

EV charging has long been discussed as a symbol of the future, but the market opens slowly in reality. 슬롯 777 EVS has been developing wireless charging from 7.7kW to 22kW. Yet the stronger message on site was the opposite.
“Wireless is up to 94% efficiency, but automated wired charging is around 99%. Right now, in terms of efficiency and reality, automated wired comes first,” Engineer Lee said.
Automated wired 슬롯 777 was described as a robot-plugging approach, but the core is not movement. It requires UWB-based proximity recognition and alignment, coupling structure, safety, and docking design under contamination conditions. Since docking failure directly destroys user experience, mechanical guidance becomes half the design.
One key message in this section was that even in the highly patented EV wireless charging field, BH EVS is structuring its technology to “bypass existing dominant patents as much as possible.” It is not just adopting - it is securing an in-house development axis. Even if the market opens slowly, the technology is already prepared.




If wireless is “the future,” automated wired charging is today’s solution. In efficiency and reality, this is the direction the market opens first. Beyond UWB-based initial alignment and position sensor control, it includes electrode-cover mechanisms - designing not “the plugging motion,” but docking that does not fail. Charging starts with design that reduces alignment failure. On site, docking, contamination, and safety conditions matter most. In the end, charging is a problem of operational quality.



Robot Charging: Mechanical Docking Design That Doesn’t Fail Is the Competitiveness

Robot charging felt like a market entering reality faster than EV charging. In service robots and mobile platforms, charging becomes part of operations - and the biggest problem in operations is always docking failure. 슬롯 777 EVS proposed a mechanically guided docking structure where alignment is automatically induced as the robot approaches. The terminal remains covered in normal conditions for safety and reduces contamination and moisture exposure risk.
The phrase repeatedly used here was “automotive-grade durability.” One product was mentioned to have completed 7,000 docking tests. Lineups with different structures, such as vertical and horizontal charging, were introduced. A notable feature was a structure that allows coupling even when the robot approaches incorrectly, moving left and right to tolerate error. The direction was clear: absorb real-world failure points through design.
This section ended not with demo tone, but with order and production tone. The message followed: “We already secured orders, and mass production is just around the corner.”



BH EVS Is Not a Company That “Seems Like It Will Do Well”
It Already Moves With a “Production Method”

Industry is ultimately decided by schedule and quality. What I confirmed in BH EVS’s private booth was not a grand future - but the strength of the present. Their explanations were not about specs, but about process. They talked first about timing, certification, heat, and claims. There were many ideas, but none were floating in the air. The process of products evolving through OEM back-and-forth was alive. Most of all, the expansion sequence was impressive. CEO Kim’s 3-pillar declaration came first, followed immediately by radar and sensor demos, then heating film and EV/robot charging - all connected by production DNA. You could feel the temperature of “accountability” toward the field - not mere possibility.
