R&D work

Improving the range of electric vehicles

On 25 October 2012, ALTEN was awarded the 2012 National Engineering Grand Prix (GPNI), in the Industry category for its R&D work in the field of energy production and storage.

GPNI, a prestigious label that rewards inventiveness, technology and innovation

The purpose of GPNI is to highlight innovative engineering projects in the fields of industry, energy, construction and infrastructure. The competition, organised since 2006 by the Ministry of Ecology, Sustainable Development and Energy, the Ministry of Productive Recovery and the Syntec-Ingénierie engineering federation, acknowledges professionals for quality of design and the development of projects that stand out for their innovation and creativity.

ALTEN, integrator of technology

IG8F01499911LYALTEN, working exclusively with an innovative SMB, handled the development of a prototype metal-air battery and the realisation of test series to identify and solve product feasibility issues. Methodologies and tools for the development of complex on-board systems were deployed at various stages of the project, to reconcile a rapid product cycle with prototype performance objectives, reliability and safety.


ALTEN also supplied overall project management by implementing a complete industrial ecosystem in an international environment:

  • Specialised French SMBs: definition of moulds, production of wiring and mechanical chassis;
  • China: production of moulds;
  • International suppliers: system components (France, Spain, USA etc.);
  • Netherlands: conversion of Combustion Vehicles to Electric Vehicles for the purposes of battery installation.

The work led to likely improvements in the autonomy of vehicles in the context of a “Range extender” approach.
