Job Description & Skill Requirement:
Details: Constructive comprehensive full-vehicle simulation models in the electrical circuit domain. Work with the simulation model development engineer and with the design/test departments to integrate multiple unit and component models to the full-vehicle simulation. Use industry tools such as Ansys Twinbuilder, Matlab Simulink, and NGspice to simulate required static and dynamic conditions of vehicle electrical systems including power, signalling, and user functions. A key distinction is that the Electrical Network Simulation Engineer owns system behavior, integration, validation, and decisions, while the modelling engineer or suppliers own the detailed component models.
1. Vehicle‑Level Simulation Strategy & Governance
Full‑Vehicle Electrical Simulation Strategy
Vehicle program-level simulation objectives and scope
Definition of required component model fidelity (architectural, predictive, real‑time)
Acceptance criteria for externally developed component models
Alignment with OEM V‑model milestones
Simulation Governance Framework
Rules for model ownership, handoff, version control, and reuse
Interfaces between component model owners and system simulation
Escalation paths for model quality, performance, or integration issues
2. Vehicle Electrical Architecture Ownership
Vehicle‑Level E/E Architecture Simulation Model
Power distribution topology (12V / 48V / HV; centralized or zonal)
ECU power domains, grounding strategy, protection philosophy
Integration of carry‑over and newly developed subsystems
Architectural Assumptions & Constraints Document
System‑level assumptions imposed on component models
Required interface behavior (pins, signals, power states, faults)
Explicit documentation of what is modeled vs. abstracted
3. Component Model Integration & Oversight
Component Model Integration Specifications
Required formats (SPICE, system‑level blocks, FMUs)
Interface definitions (causality, I/O, parameters, units)
Performance and numerical stability requirements
Model Acceptance & Readiness Reviews
Technical review of supplier or internal component models
Verification against interface contracts and expected behavior
Approval for integration into full‑vehicle simulations
Model Compatibility Matrix
Supported tool versions and solvers
Known limitations and interaction risks between models
4. Full‑Vehicle Electrical System Models
Integrated Full‑Vehicle Electrical Network
Assembly of batteries, power electronics, ECUs, and loads
Harness‑level effects (voltage drop, shared grounds, protection)
Variant handling (trim levels, regions, propulsion variants)
System‑Level Abstraction Layers
Reduced‑order or averaged representations for large‑scale studies
Fidelity switching strategy (architecture vs. transient vs. real‑time)
5. Co‑Simulation & Digital‑Thread Integration
Multi‑Domain Co‑Simulation Setup
Electrical-controls-thermal interfaces
Synchronization strategy and solver coordination
Interfaces to vehicle dynamics and energy management models
FMI / FMU Integration Deliverables
System‑level or subsystem FMU assemblies
Validation of interfacing behavior between FMUs
Tool‑agnostic deployment for downstream teams
6. Vehicle Operating Scenarios & Studies
Standard Automotive Use‑Case Results
Startup, shutdown, sleep/wake cycles
Cold crank, peak load, load dump, brownout
Charging and regenerative braking behavior
Trade Studies & Design Decisions
Architecture alternatives (e.g., zonal vs. domain)
Energy flow and power budgeting studies
Sensitivity analyses across variants and environments

Job Requirement
Use industry tools such as Ansys Twinbuilder, Matlab Simulink, and NGspice for modelling in support of simulation for static and dynamic analysis
