Battery System Architecture

Dual Architecture Mastery: CTP vs. MTP Integration

We don’t force a one-size-fits-all structure. Whether bringing bare cells for maximum energy density or pre-validated modules for ultimate serviceability, our engineering facility adapts to your distinct operational reality.

Module to Pack Integration

Module-to-Pack (MTP) Architecture

Best for Marine, Remote Mining, Ultra-Heavy Duty Platforms

You bring standard CALB/CATL/EVE modules. We design the ruggedIZED enclosures , integrate pack-level dual-cooling cold plates , and write bespoke Master-BMS logic to handshake seamlessly with your vehicle CAN bus.

Why Choose MTP?

Ideal for operations where downtime is unacceptable. MTP enables module-level isolation, targeted fire suppression, and rapid field replacement without removing the full battery pack.

Our MTP Expertise

  • • Vibration Decoupling: Multi-stage damping mounts for off-highway shock loads and vibration.
  • • Modular Thermal Bridging: Precision thermal pads equalizing cooling performance across modules.
  • • High-Voltage Busbar Routing: Rigid/flexible busbars engineered for >1000V heavy current systems.
Cell to Pack Assembly

Cell-to-Pack (CTP) Engineering

Best for Long-Haul Trucks, Weight-Constrained EV Platforms

You bring the bare prismatic or cylindrical cells. We handle the precision laser welding, busbar design, cell-level Thermal Interface Material (TIM) application, and structural bonding up to IP67 standards.

Why Choose MTP?

Maximizes volumetric efficiency by removing module housings, unlocking more payload capacity and longer driving range through superior internal packaging density.

Our CTP Arsenal

  • • Advanced Structural Gluing: Cells bonded directly into cooled trays using structural adhesives.
  • • Automated Tab Welding: Vision-guided laser/ultrasonic joining for zero-defect high-speed assembly.
  • • Aerogel Cascading Protection: Aerospace-grade barriers preventing cell-to-cell thermal propagation.
Advanced Manufacturing Technologies

In-House Advanced Manufacturing: We Treat Your Cells/Modules Like Gold

Have a strategic supply of cell modules? Perfect. We offer complete Module-to-Pack (MTP) and Cell-to-Pack (CTP) assembly services. From precision busbar laser welding and BMS wire-harness routing, to thermal interface material (TIM) dispensing and final high-voltage sealing. Your tier-1 modules are integrated within our ESD-compliant cleanrooms, turning your raw energy into a plug-and-play powertrain system.

Ultra-Precision CNC & Enclosure Fabrication

Ultra-Precision CNC & Enclosure Fabrication

End-to-End Engineering，Point-to-Point Execution

A bare battery module is nothing more than raw chemical potential. Without a rugged structural fortress, extreme thermal management, and a highly intelligent high-voltage nervous system, it cannot survive the harsh realities of commercial EV and marine applications. We don't do "off-the-shelf" compromises. We custom-engineer the exact physical and digital architecture your heavy-duty powertrain demands.

Flexible Architecture Typologies

Adapting to Any Chassis, Empowering Every Platform

Multi-Pack Standalone Setup

Multi-Pack Standalone Setup

For large-scale string configurations, we deploy a dedicated, standalone Battery-Side PDU (High-Voltage Control Box). This externalizes the high-voltage routing and master control, making it easier to manage multi-pack logic and high-current distribution safely.

All-in-Pack Integration

All-in-Pack Integration

When chassis real estate is strictly limited, we consolidate the PDU functionalities and Master BMS directly into the single battery pack enclosure. This "All-in-Pack" solution drastically reduces external wiring harness complexity and saves critical weight.

OEM Synergy Architecture

OEM Synergy Architecture

Many OEMs now integrate DCDC, MCU, and Vehicle-side PDUs into 3-in-1 or 4-in-1 units. We play perfectly with this ecosystem. We strip away redundancies and provide purely what the battery system needs (e.g., a lean battery-side PDU or integrating the master battery control into your domain controller) to handshake flawlessly with your advanced powertrain setup.
