ISO versus IEC

  • Cultural differences

–Automotive sector –Electrotechnical sector

  • Division of labour

ISO TC22 SC21 IEC TC69

Aspects related to the electric vehicle as a whole Aspects related to electrical components and electric supply infrastructure

Vehicle performance standards

  • ISO 8714:2002 Energy consumption and range for

battery-electric vehicles

–Based on regional test cycles

Vehicle performance standards

  • ISO 23274 Hybrid-electric road vehicles - Exhaust

emissions and fuel consumption measurements

–Part 1 Non externally chargeable vehicles (2013 Ed.2) –Part 2 External chargeable vehicles (2012 Ed.1)

Drivetrain Component Standards

  • Extensive standardization for industrial traction

motors (IEC 60349)

  • No demand from automotive industry !
  • No tradition in automotor standardization
  • IEC TC69 WG2 disbanded

  • ISO: Vehicle-centric

–Battery system –ISO 12405 family

  • IEC: Battery-centric

–Battery cells –IEC 62660 family –IEC 61982

Other RESS

  • Electric double-layer capacitors: IEC 62576
  • New components: hybrid capacitors

–New standards needed?

  • New applications: second-life

–Test cycles for stationary applications –State of health determination
