⚡ Power & Energy
  • Energy (Platform Range)
    10–200+ kWh

    High-mix platform supporting wide energy range. Final installed energy depends on module variant selection, array count, enclosure choice, and duty cycle requirements. Use the online configurator for quick estimates; we generate configuration-specific datasheets on request.

  • Module Variants (24-cell)
    1s, 2s, 3s, 4s, 6s

    Series configuration options for the 24-cell building block. Each variant provides different voltage/capacity trade-offs. Parallelization and pack topology (series/parallel arrangement) are selected per program based on system voltage and energy requirements.

  • Modules Per System
    18–144 (18/array)

    Typical envelope supports 1–8 cooling arrays with 18 modules per array. Actual module count depends on control shelf configuration and enclosure selection. Each cooling array is an independently serviced thermal zone.

  • Cell Chemistry
    NMC/NCA Lithium-Ion

    High energy density cylindrical cells (21700/18650 formats). Cell selection is program-specific based on power/energy/life requirements. All cells undergo incoming quality control and formation cycling before module assembly.

📦 Physical & Environmental
  • Operating Temperature
    Charge: 0–60°C • Discharge: −40–60°C

    Storage range: -40°C to +85°C. Power derates and cold-soak heating protocols are program-specific per integration requirements. Thermal solution choice (air/liquid cooling) and enclosure selection affect operational temperature limits.

  • Specific Energy
    Module: ~100–110 Wh/kg

    Module-level specific energy basis. System-level specific energy varies with enclosure mass, harnessing, mounting hardware, and cooling system selection. Typical system-level: 80-95 Wh/kg depending on configuration.

  • Environmental Protection
    IP65+ (enclosure dependent)

    Ingress protection rating depends on enclosure selection. Module arrays are designed for sealed environments. Vibration and shock profiles are verified against program-specific test plans (e.g., MIL-STD-810, SAE J2380).

  • Dimensions
    Program-specific

    Overall pack dimensions vary with array count and enclosure design. Standard module dimensions: varies by series configuration. Full mechanical models (STEP files) provided for vehicle integration planning.

🛡️ Safety & Control
  • Safety Architecture
    Multi-layer Protection

    Defense-in-depth approach: Cell CID (current interrupt device) → Wire-bond redundancy with fuse-like behavior → Pack-level fusing → BMS monitoring and software limits. Each layer provides independent protection against fault propagation.

  • Control Model
    VCU-master; BMS enforces safety

    BMS supervises HVIL (high-voltage interlock loop), precharge sequencing, and contactor control. Publishes real-time limits (current, power, voltage) and health metrics on CAN bus. Vehicle Control Unit (VCU) commands loads within published limits. Clear authority partitioning for safety-critical functions.

  • Communications
    CAN 2.0B (11/29-bit)

    Full telemetry, limits, and fault reporting via CAN 2.0B. DBC file provided with all signal definitions. ICD (Interface Control Document) specifies message IDs, update rates, and timing requirements. Message IDs and rates configurable within documented bounds for multi-pack systems.

  • Certification Path
    UN 38.3 / UL 1973 program-ready

    Not a pre-certified pack. We supply the documentation package and test plans required to run certification on your final configuration. Test protocols aligned with UN 38.3 (transport) and UL 1973 (stationary energy storage) as applicable to program requirements.

🔌 Electrical Interface
  • System Voltage
    48V to 800V nominal (configurable)

    Nominal system voltage determined by module series configuration and pack topology. Common configurations: 350-400V (light vehicles), 600-800V (heavy-duty). Min/max voltage limits provided in configuration-specific datasheet.

  • HV Connectors
    Amphenol / TE / Program-specific

    High-voltage connector selection based on current requirements and program preferences. Standard options include Amphenol HVP series and TE HVIL connectors. All connectors include integrated HVIL signaling for safety interlock verification.

  • Auxiliary Power
    12V / 24V input (program-specific)

    BMS requires low-voltage auxiliary power for control and monitoring functions. Standard configurations support 12V or 24V vehicle systems. Power consumption: <10W idle, <50W active (including contactors and cooling pump/fans).

Engineering Features & Benefits

MonoLith™ delivers production-relevant architecture and safety systems while maintaining the flexibility required for iterative prototype development. Key engineering advantages for vehicle integration teams:

  • Lower contact resistance vs. spot welds (reduced I²R losses)
  • No thermal stress on cell terminals during assembly
  • Field-proven in demanding military and industrial applications
  • Enables rapid module rework and cell replacement during development

Development Platform Notice

MonoLith™ BMS limits and protection thresholds are software-configurable to support iterative development. This is a prototype platform feature, not a production pack architecture. All limit changes must be documented and validated against cell specifications. Production packs require hardware-enforced safety limits.

Integration & Deployment

MonoLith™ ships as a complete turnkey system with comprehensive documentation for vehicle integration. Typical deployment timeline: 4-8 weeks from order to first vehicle operation.
