EMC for electric vehicles

Objectives

  • Review the new EMC requirements for electric vehicles.
  • Review the new EMC requirements incorporated into standards and specific to electric vehicles and their subassemblies (CISPR 25 ed.2016 and ECER10 rev.5).
  • Define the integration rules applicable to sub-assemblies installed in electric vehicles: equipotentiality, faradisation, shielding of harnesses, etc.
  • Present test setups in the laboratory and carry out measurements on demonstration models.

 

Who should attend ?

Engineers and technicians responsible for the integration and EMC qualification of electrical/electronic sub-assemblies used in electric vehicles (EVs) and hybrid vehicles (HEVs).

 

Prerequisite

Hold an engineering or technical degree (or equivalent) in the following fields: electrical/electronic/electrotechnical.

 

Technical and learning resources

Presentation aids for lectures, case studies, demonstration models, test equipment for practical training courses

 

Sanction of training

Certificate of completion

Methods of assessment

QUIZ evaluation questionnaire

Presentation

This course reviews all the EMC constraints(normative/contractual, for integration and at test level) to be taken into account for the integration and qualification of on-board sub-assemblies in electric vehicles. Part of the course will be carried out in our laboratories, so that participants can work on practical cases.

 

Program

1 - Identify the new EMC constraints associated with electric and hybrid vehicles.

Present the architecture of an EV and VH powertrain-List the main contributors to electromagnetic (EM) disturbances - Define the existing couplings for each sub-assembly - Characterize their electromagnetic spectrum (types of disturbances generated, propagation modes, frequency bands, etc.).

 

2 - Present the new standards requirements

Distinguish: Conducted emissions/radiated emissions: CISPR 25 Edition 2016 vs ECE R10 revision 5, Vehicle (Setups; Limits) - Electrical and electronic sub-assemblies (Setups; Limits) - Conducted/radiated immunities (BCI, Radiated immunity, ESD, fast transients), Setups - Limits - Summarize the requirements of manufacturers' specifications and identify their specific features (Renault-Nissan, PSA, VW etc.).

 

3 - Describe best practices for integration in Evs

Define the rules for equipotential bonding (electrical/electronic ground, mechanical ground, etc.) - Address the notions of interior and exterior - Clarify best practices in mechanical shielding for subassemblies generating strong EM fields - Apply best practices in beam shielding - Present existing solutions: suppliers, models, datasheets, etc.

 

4 - Apply concepts in the laboratory

Carry out testing set-ups: conducted and radiated emissions - Study real cases from tests carried out in our laboratories (powertrain, inverter, etc.) - Analyze measurement curves
