Historical development

•IEC TC69: Founded 1969

• ISO TC22 SC21 founded in 1973

•Difference in standardization culture

4

ISO TC22 SC21 IEC TC69

Aspects related to the electric vehicle as a whole

Aspects related to electrical components and electric supply

infrastructure


ISO: vehicle-oriented

•Vehicle safety (ISO 6469 series)

•Vehicle performance

•Battery as a system (ISO 12405 series)

5


IEC: components and infrastructure

•Drive train components: no interest in standardization

•Batteries (JWG TC21/SC21A/TC69)

–IEC61982: non-lithium

–IEC62660: lithium (cells and modules)

–IEC62576: capacitors

–Test cycles corresponding to real operation in a specific application

Infrastructure standards (TC69)

• Conductive charging: IEC 61851

–Definition of “charging mode” concept

•Mode 1: non-dedicated outlet

•Mode 2: non-dedicated outlet, in-cable control box

•Mode 3: dedicated outlet, control pilot

•Mode 4: d.c. charging

– 3rd edition being prepared

• Wireless charging: IEC 61980

8


Interactions

•Vehicle issues (ISO TC22 SC21)

•Accessories (IEC SC23H)

•Low voltage installations (IEC TC64)

•Assemblies (IEC SC17D)

•Smart grid (IEC TC57)

9


Accessories

•Plugs, sockets and connectors for a.c. and d.c.

10


Charging communication

•Basic control pilot function in Mode 3

•Specific d.c. communication with battery

•High level communication between vehicle and charging post: ISO/IEC 15118

•Development of advanced and complex business models (billing, roaming, etc.)

11


European standardization

•CENELEC TC69X

•1990s: parallel work with IEC

–not efficient

•Dormant 2000s when IEC documents published

•Reactivation 2012

12


The Mandate

• Mandate M/468

• Issued by European commission June 2010

• Addressed to CEN, CENELEC and ETSI

• Ensure interoperability, connectivity, safety and electromagnetic compatibility

• CEN/CENELEC Focus Group to make recommendations in response to mandate

– Collaboration between relevant committees and European standard organizations

– Standardization needed for interoperability13


Draft directive

•January 2013

•Development of infrastructure

•Mode 3 charging

•Type 2 accessories for a.c.

•Combo accessories for d.c.

•Under preparation with consultation of CEN/CENELEC Steering Group

14


Standardization process

•European committees (CLC TC69X and CEN TC301) reactivated

•Avoid parallel work: follow work on international level (IEC, ISO) and adapt international standards as EN

•European work only where deemed necessary for specific European requirements

So many committees, so many standards...

• Sectoral division: IEC versus ISO

–Field of competence

–Standardization culture: electrical and automotive

• Regional division:

– international standards

–European standards

–national standards

• Regulations versus standards

• But they all have to agree....17


State of standardization

•Standardization: a microcosmos of society–Players

–Interests

–Interactions

–Cultures

18


The strength of standards

•Bottom-up process

•Drafted by technical experts

•Established by consensus

•Aimed at the achievement of the optimum degree of order in a given context

•Democratic voting process

19


The problems

•Slow process due to consensus principle

•Plethora of conflicting standards

•Overstandardization

“Standardization is a useful servant, but a bad master”N.F. Harriman, 1928

20


Where do we go from here

•The ideal of infrastructure standards

–Any vehicle should be able to safely charge anywhere
