Systems Engineering for Mission-Critical Projects

Do it Once

Comprehensive front-end planning prevents costly rework. Solid requirements, clear architecture, and disciplined scope control from day one.

Do it Right

What is Documented is Done. Customer needs translated into measurable specs, clear subsystem responsibilities, and every requirement verified.

Do it Fast

Speed through efficiency. Test early, test often. Parallel workstreams on independent subsystems. No late-stage failures or rework.

V2G Charging Infrastructure Field Investigation

Client: EVPV LLC | Role: Technical Consultant / Subject Matter Expert

Independent technical investigation of bi-directional V2G (Vehicle-to-Grid) DC fast charging infrastructure deployed at school district sites. The investigation focused on electric school bus charging systems designed to enable grid energy storage through bidirectional power flow.

Technical Scope

  • 60kW and 125kW bi-directional DC fast chargers with V2G capability
  • Protocol analysis: DIN 70121, ISO 15118, OCPP, SLAC, and PSD measurements
  • Gen3E, Gen3S, and Gen3 1:1 dispensers interfacing with Power Conversion Systems
  • GIVe software platform integration and grid management systems

Investigation Areas

  • Reliability Assessment: Documented systematic failure patterns, fault codes, and forced stops requiring remote intervention
  • Interoperability Analysis: Evaluated communication between charging hardware and V2G software platforms
  • Commissioning Verification: Identified commissioned vs. uncommissioned units and deployment quality
  • Warranty Compliance: Reviewed manufacturer response timelines, root cause analyses, and repair obligations
  • Protocol-Level Diagnostics: V2G analyzer deployment for DIN session analysis and OCPP compliance verification

Impact

The investigation supported school districts operating electric school bus fleets where infrastructure reliability directly affects daily transportation schedules. Comprehensive field reports with photographic and data log evidence provided independent technical assessment of product reliability and specification conformance, suitable for litigation support.

This project exemplifies the critical need for independent, vendor-neutral technical expertise in the rapidly evolving EV charging infrastructure space—where real-world reliability often falls short of manufacturer claims and contractual specifications.

Our Methodology

We employ Model-Based Systems Engineering (MBSE) frameworks aligned with ISO/IEC/IEEE 15288 to deliver predictable, robust outcomes. Our approach spans the complete system life cycle:

Business & Mission Analysis

Understanding the "why" before defining the "what." We gain deep comprehension of your system's purpose and stakeholder needs.

  • Customer Value Proposition & Log Line Development
  • Customer Affinity Process for Needs Identification
  • Annotated Concept Sketches & Storyboarding
  • Context Diagrams for System Boundaries
  • Use Cases, User Stories & Behavioral Diagrams
  • SysML Use Case Diagrams

Requirements Engineering

Translating stakeholder needs into clear, verifiable specifications. Every requirement is traceable, measurable, and allocated.

  • Originating & Derived Requirements Tables
  • Requirement Constant Definition Tables (RCDT)
  • SysML Requirements Diagrams
  • QFD / House of Quality for Requirements Translation
  • Goal-Question-Metric (GQM) Method
  • Requirement Allocation to Subsystems

Architecture & Design

Establishing solid foundations through systematic decomposition. We define subsystems, interfaces, and functional relationships.

  • Sub-System Definition & Allocation (SSDA)
  • Functional Flow Block Diagrams (FFBD)
  • IDEF0 Functional Modeling
  • SysML Activity & Sequence Diagrams
  • State Diagrams & Matrices
  • Interface Matrix & Specification Management
  • Operational Description Templates (ODT)
  • SysML Parametric Diagrams

Decision Analysis & Trade Studies

Objective evaluation of alternatives using quantitative methods. We eliminate bias and document rationale for future reference.

  • Concept Fragment Generation
  • Combination Tables / Morphology Boxes
  • Decision Matrices with Weighted Criteria
  • Analytical Hierarchy Process (AHP)
  • Design for X Analysis (Reliability, Maintainability, Manufacturability)

Verification & Validation

"Test Early, Test Often." Rigorous V&V confirms designs meet specifications and stakeholder needs are satisfied.

  • Behavioral & Non-Behavioral Test Plans
  • Verification Cross Reference Matrix (VCRM)
  • Test Methodology for All Requirement Types
  • Integration & System-Level Testing

Risk Management

Proactive identification and mitigation of system vulnerabilities. We quantify risk and prioritize corrective actions.
