Designing and optimizing vehicles from architecture to series life

DEMS is the brand of the TEC E MOUV Group dedicated to the complete engineering of vehicles, from their global conception to their production setup and homologation.

We intervene on the entire vehicle: architecture, systems integration, regulatory compliance, and preparation for series life.

Our role: transform an elegant concept or an existing vehicle into a viable, homologated, and ready-to-deploy industrial product.

Qui nous sommes

Designing a vehicle means mastering all of its constraints

A vehicle is a complex system, at the intersection of multiple requirements: technical, regulatory, industrial, and economic.

Our use cases

Rétrofit complet de chaîne de traction  intégration système, structure et validation multi

Complete powertrain retrofit: system integration, structure, and multi-physical validation

Engine / chassis interface design: mounts, anchor points, and structural adaptation on an existing base.

Powertrain implantation: optimized mechanical integration / maintenance / assembly.

→ Multi-physical dimensioning (torque / vibrations): validation of stresses and mechanical resistance.

→ Integration of auxiliary systems & HV wiring harnesses → full electrical architecture.

→ Thermal & energetic validation: simulation and functional mock-up.

→ Complete prototype dossier: base ready for industrialization or pre-homologation.

Développement d’un bus électrique architecture globale, intégration système et design-to-i

Electric bus development: global architecture, system integration, and design-to-industrialization

→ Complete vehicle architecture design: structure, propulsion, energy, and series interfaces.

Electric powertrain integration: optimized packaging and embedded performance.

→ Mechanical and electrical systems development.

Weight / cost / industrialization optimization: design oriented towards fabrication and series production.

→ Complete vehicle fine-tuning: functional and dynamic validation in real-world conditions.

→ Multi-disciplinary coordination in a short cycle (~12 months).

Energy conversion of a bus to hydrogen: system integration, safety, and vehicle industrialization

→ Propulsion architecture transformation: complete overhaul of the energy chain.

→ Fuel cell system + H2 storage integration.

Full electrical and thermal reconfiguration: multi-source energy flow management.

→ Safety studies and regulatory compliance: factoring in H2 constraints right from design.

Mechanical integration on an existing platform: structural adaptation and vehicle interfaces. → Complete vehicle system validation: global operation in real operating conditions.
