High-Voltage & Intelligence
Unifying bespoke PDU hardware, cognitive BMS logic, and adaptive topologies. We engineer your system’s muscle, blood vessels, and brain to fit real chassis limits, real integration headaches, and real heavy-duty duty cycles.
We Do Not Stack Components. We Architect Survival
Building a robust commercial or marine powertrain requires more than cell modules and a control box. It demands a system-engineering philosophy where hardware, power routing, thermal flow, and protocol logic endure as one body. In harsh environments, single-point failure is not an option.
PDU & Housing
Megawatt-level resilience wrapped in precision-machined high-voltage enclosures, reinforced contactor strategy, and safety-first interlock design.
Harness & Interfaces
Custom high-voltage wiring, communication harnesses, connectors, and leak-proof cooling pipes that keep energy and heat moving without interruption.
BMS & CAN Logic
Deep SOX calibration and CAN matrix translation that let the pack, VCU, and charger speak the same language before first vehicle power-up.
Bespoke PDU & HV Control Boxes
This is where customers decide whether a custom system is truly industrial-grade or just a dressed-up prototype. We design PDU hardware and high-voltage control boxes for heavy-duty duty cycles, complex mounting directions, and unforgiving protection requirements.
The Nomenclature of Power
Whether you call it PDU, HVB, or a Master Control Box — we understand exactly what you mean. More importantly, we engineer it to perform flawlessly within your system architecture.
PDU (Power Distribution Unit)
Built for vehicle-level power distribution in heavy-duty trucks and marine platforms. It routes high current precisely to key loads—MCU, DC-DC, compressors, and PTC/OBC—while keeping the architecture clean and efficient.
- Routes high current to MCU, DC-DC, compressors, PTC/OBC
- Safety-focused distribution and protection
- Reliable integration for trucks and marine platforms
HVB (High-Voltage Box / BDU)
An integrated battery-level high-voltage switching and protection hub. It combines main positive/negative contactors with a pre-charge circuit to ensure controlled HV ramp-up and fault protection.

- String current sharing and balancing
- Emergency disconnect capability
Deep Dive into Electrical Engineering
This is where engineering competence becomes visible. Beyond packaging components, we apply real design-for-manufacturing logic to current paths, protection architecture, and enclosure integrity — ensuring every system is robust, safe, and production-ready.
Busbar Thermal Dynamics
We do far more than route conductors. Through current loading calculations and thermal simulation, we engineer custom copper or aluminum busbars, optimize plating and lamination strategies, and ensure temperature rise at terminals remains below 30K.
Arc-Flash Mitigation & Short-Circuit Protection
Protection architecture is precisely coordinated between contactors and high-voltage fuses, including pyrotechnic fuses and aR/gR fuse strategies. This ensures millisecond-level interruption during short-circuit events, minimizing the risk of catastrophic failure.
Packaging & IP Rating
Structural integrity matters as much as electrical performance. We perform modal analysis for vibration resistance, support both CNC machining and die-cast aluminum housings up to IP67 / IP68 protection levels, and integrate full EMI / EMC shielding measures for system stability.
Uninterrupted Power & Thermal Routing
Megawatts of power and massive thermal loads are useless if they cannot be transported safely. We engineer the critical arteries of your entire battery system. From high-voltage shielding against extreme EMI, to hyper-reliable fluid loops that obliterate localized hotspots, we ensure your energy and thermal flows remain completely uninterrupted, even under heavy-duty vibrations or severe salt-fog conditions.
🔌 Interfaces Selection
We specify battle-proven mil-spec circular connectors and EV-grade interfaces from TE, Amphenol, Jonhon and Recodeal to ensure rock-solid power and signal transfer. Built for repeated mating cycles, harsh vibration, and demanding environments, these connections are engineered to perform where failure is not an option.
⚡ High Voltage Wiring Harness Customization
Our custom high-voltage harnesses combine overbuilt shielding, high-flex cable construction, and elevated temperature resistance for safe, stable routing through heavy-duty chassis. From tight packaging to punishing vibration, they are engineered to protect power delivery in the toughest operating conditions.
📶 Communication Wiring Harness Customization
We engineer communication harnesses with tightly controlled twisted pairs and robust shielding to preserve signal integrity in EMI-heavy environments. The result is stable, interference-resistant communication across your BMS, sensors, and vehicle control networks.
❄️ External Cooling Pipes / Tubes Customization
Our external cooling pipes and tubes feature rapid-connect, leak-tight designs that seamlessly link battery cooling plates to the vehicle’s thermal loop. Engineered for durability, serviceability, and consistent flow performance, they keep thermal management dependable in real-world operating conditions.
Advanced BMS & VCU Handshake
Intelligent SOX logic must match the actual chemistry, the actual use case, and the actual vehicle controller on day one. We bridge the gap between pack-level cognition and vehicle-level execution with protocol mapping, calibration logic, and handshake validation before hardware launch.
SOC, SOH, and SOP tuned to cell behavior, temperature profile, and platform mission.
Matrix design that lets our pack, your VCU, and charging infrastructure communicate cleanly.
Provide your VCU requirements and handshake logic. We map the CAN matrix before the first housing is ever machined, reducing integration risk where it hurts most: first prototype bring-up.
Select Your BMS Architecture. We’ll Engineer the Integration
Different machines demand different system designs. Our architecture options let you balance cost, modularity, and safety without compromise. Once you choose the direction, we deliver an integration plan engineered for your application—robust comms, clean harness routing, and compliance-ready redundancy where it matters.
Centralized BMS
All cell sense leads are consolidated onto a single PCBA—ultra‑low cost, with a harness routing and anti‑chafing design optimized for compact, irregular (odd‑form) packs.
Distributed BMS
Highly modular architecture: a failure in any one pack won’t compromise the overall system. We ensure robust EMC shielding for high‑speed CAN and long‑distance daisy‑chain communications.
Multi-level Master BMS
Fully compliant with DNV and other classification societies (e.g., CCS) single‑point‑failure redundancy requirements for 100‑MW‑class systems.
We Speak Your Machine's Language
The hard part isn’t the hardware—it’s the handshake. We make your battery pack communicate flawlessly with your vehicle and local chargers, supporting CAN standards (SAE J1939 / CANopen / NMEA 2000) and global DC fast charging protocols: CCS2 (DIN 70121 / ISO 15118), CHAdeMO, and GB/T 27930.
Vehicle Integration
We’re experienced in configuring and exposing CAN matrices, and we provide full compatibility with industry-standard protocols—SAE J1939 for commercial vehicles, NMEA 2000 for marine applications, and CANopen for industrial machinery.
Global DC Fast Charging
We handle low-level protocol tuning and commissioning to ensure your battery pack can reliably authenticate and charge across the major standards: CCS2 in Europe (DIN 70121 / ISO 15118), CHAdeMO in Japan, and China’s GB/T 27930.
A World-class Brain Needs A Resilient Supply Ecosystem
Your system should not collapse because one chip, one protocol path, or one software branch becomes a bottleneck. This section is designed to communicate strategic ecosystem depth, localized supply flexibility, and continuity for global programs.
Flexible Topologies, Engineered Around You
Even the most advanced hardware and control logic must work within the physical limits of your chassis. That’s where standard commercial packs fall short—and where our custom architecture stands apart. Whether you need to navigate irregular hull spaces on a heavy vessel or remove unnecessary hardware from a next-generation OEM platform, we don’t force a one-size-fits-all solution onto your vehicle. Instead, we tailor the master control logic and high-voltage distribution architecture to match your exact space and performance requirements.
