Your challenges

Do you need to comply with new and expensive emissions standards?
Do your customers want you to reduce the TCO of your vehicles by reducing fuel consumption?
Is it the market trend, or are your customers pushing you towards hybrid or electric?
Don’t you have the internal resources to lead an electric revolution?

Our tailor-made solutions

Too often, we meet customers who have failed in their “electrification path” because of misguided choices that lead to mixed technical or commercial success.

From the plug-in hybrid to the electric on batteries, with more than 25 years of experience, Green Propulsion Engineering (GPE) has the expertise to help you move towerds the right path.

Our approach guarantees future commercial success through a proven development methodology, from the first idea to the finished product:

  1. By simulation, demonstration of technical and economical feasibility
  2. Mechanical and electrical integration of the system
  3. Prototyping – Pre-production
  4. Validation, testing and approval of the system/vehicle
  5. Small-scale production

Our services cover phases 1 to 5. We can also step in and out on an as-needed basis.

Demonstration of feasibility via simulation

GPE technical and economical simulation tools portfolio includes performances, gradeability, energy consumption / CO2 emissions, range of the vehicle, … but also the end-user Total Cost of Ownership (TCO).

Based on the specific duty cycles of the application, GPE target is to find the best compromise between key factors e.g. the performance, the energy efficiency, the reliability, the development cost, …

Simulation also eases the cost effective evaluation of diverse electrified solutions: series and/or parallel hybrid, electric?

Mechanical and electrical integration of the system

Thanks to its deep understanding of the complete system, GPE also provides a complete set of integrator services, based on its large database of long-term partners (e.g. engines, motors, battery manufacturers, transmission specialist):

  • The 3D mechanical integration of the engine, the motor(s), the battery and their accessories within an existing vehicle chassis / body and eventually the design of a specific transmission
  • Possible design of a specific transmission.
  • Heat management.
  • Electrical, electronic and software (BMS, VMU) integration: specific wiring diagrams, CAN communication protocol, possible dedicated electronics, etc.
  • Metropol energy management software, thanks to our multi-target optimization algorithm.

Prototyping / pre-production

Thanks to a staff of senior technicians, these engineering concepts turn into reality in GPE well-equipped workshop, with a fully functional validation prototype and/or directly a pre-series:

  • Prototype systems
  • Vehicle conversion
  • Prototype complete vehicle
