Our skills in instrumentation, control software and mechanical expertise on cells, modules and packs go along our expertise in testing.

LOGISTICS

From the transport of your batteries to their dismantling and recycling.

Standards and test methods

Whether for transport (UN 38.3), homologation (ECE R100, ECE R10...) or design and validation, standards and test methods are powerful tools to develop more efficient and safer batteries.

EMC along with the other affiliates of the Group brings you a global solution.

Our support dedicated to electric motors

Moteur électrique

Our testing facilities are designed for a wide range of electric motors and are associated with battery simulators corresponding to their purpose.

 

Our dedicated facilities for electric motors complete those for ICS, hybrid, plug-in hybrid, micro-hydrides 

Characterization and validation of electric motors

Depending on whether the vehicles are hybrid, full electric or even use a hydrogen fuel cell, different service options are to be considered:

Adapted resources to the requirements of electric motors

Managing change

Know-how focused on the future technologies

The electrification market is not limited to cars and trucks: light vehicles, off-road mobile machineries, VTOL (Vertical Take-off and Landing aircraft)... 
Our engineering department dedicated to the design of benches has developed solutions to meet the expectations of our customers.

  • High speed and high dynamics in a package solution - Back-to-back bench up to 30'000 rpm
  • Micro-hybridization (Mild-Hybrid), light vehicle or retrofit solution: ICE dynamometer + gearbox up to 20'000 rpm on electric motor

 

Pulsar

Our own-developed control and acquisition software solution PULSAR is adapted to the electric motors specificities.

PULSAR manages the security of our benches and allows the recording at 10Hz of an assembly of up to 200 measuring channels and performs the control of the benches and the rapid acquisition of data of the tested equipment.

Our software suite extends with:

  • PULSAR Graph: Tool for viewing recordings and post-processing
  • PULSAR Vibes: Tool for vibratory monitoring 
  • PULSAR Mobile: Embedded version to quickly set up acquisitions in a bench or to realize embedded acquisitions in a vehicle.

The PULSAR suite is the result of an exclusive development started more than 10 years ago and is updated very regularly.

This suite is based on solutions from National Instruments

 

With its modular design, our solution is flexible and quick to adapt, it allows us to meet the challenge of technological developments in the mobility sector:

  • Control of any industrial device (Modbus, EtherCat, LAN,...)
  • The integrated CAN supervisor allows sequencing from the device data.
  • Sampling at 10kHz for HV bus monitoring
