MEV Thermal Solid‑State Battery Housing Platform™
Systems-Level Thermal & Structural Integration Concept
By Michael Kent West

The MEV Thermal Solid‑State Battery Housing Platform™ is a next‑generation battery enclosure architecture engineered for scalable integration across passenger, commercial, and heavy‑duty EV platforms. Designed through a systems‑thinking lens, the platform unifies thermal management, structural safety, serviceability, and environmental durability into a single modular housing concept optimized for solid‑state energy storage.

This project emphasizes real‑world reliability in northern climates, manufacturability using automotive‑grade processes, and seamless integration with vehicle‑level thermal and controls systems.

Engineering Objectives
Reduce Thermal Gradients (ΔT Control) — Achieve uniform module temperatures during fast charging and high‑load operation to improve performance consistency and lifespan.

Improve Cold‑Start Charge Acceptance — Reduce preconditioning energy demand and accelerate readiness in freeze‑thaw environments.

Isolate Service Electronics — Separate high‑voltage service components from the main cell cavity to enhance maintainability and contamination control.

Design for Northern Environmental Durability — Address salt spray, slush packing, ice expansion, and corrosion exposure.

Enable Modular Scalability — Support architectures ranging from SUVs to heavy‑duty commercial platforms.

Key System Innovations
Thermal Break Perimeter Ring™
A composite isolation ring separating the outer crash frame from the sealed cell tub.
Value: Reduced conductive heat loss, improved pack temperature balance, and lower winter energy overhead.

Dual‑Platen Thermal Clamp System™
A bottom microchannel cooling plate paired with a top equalization plate integrated into the lid.
Value: Bidirectional heat management, reduced vertical gradients, and enhanced fast‑charge thermal control with closed‑loop coolant strategies.

Electronics Attic Compartment™
A dedicated, service‑accessible zone housing the HV junction, contactors, pre‑charge circuitry, and BMS controls.
Value: Field service without breaching the main cell cavity, simplified diagnostics, and reduced resealing complexity.

PCM Peak Shave Zones™
Strategically placed phase‑change material inserts near high‑current regions.
Value: Mitigates short‑duration thermal spikes, reduces cooling loop stress, and protects solid‑state electrolyte interfaces.

Michigan Winter Ingress Geometry™
Ice‑shedding skid plate, double‑lip labyrinth seal, pressure‑equalization membrane, and corrosion‑resistant design.
Value: Freeze‑thaw resilience, reduced seal fatigue, and long‑term durability in northern markets.
