6.5.2017 | EN | Official Journal of the European Union | L 118/20 ---|---|---|--- * * * COMMISSION IMPLEMENTING DECISION (EU) 2017/785 of 5 May 2017 on the approval of efficient 12 V motor-generators for use in conventional combustion engine powered passenger cars as an innovative technology for reducing CO2 emissions from passenger cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EC) No 443/2009 of the European Parliament and of the Council of 23 April 2009 setting emissions performance standards for new passenger cars as part of the Community's integrated approach to reduce CO2 emissions from light-duty vehicles (1), and in particular Article 12(4) thereof, Having regard to Commission Implementing Regulation (EU) No 725/2011 of 25 July 2011 establishing a procedure for the approval and certification of innovative technologies for reducing CO2 emissions from passenger cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (2), and in particular Article 10(2) thereof, Whereas: (1) | The application submitted by the supplier Valeo Electrical Systems on 21 July 2016 for the approval of the efficient generator function of the 12 V i-StARS belt-driven starter-alternator as an eco-innovation has been assessed in accordance with Article 12 of Regulation (EC) No 443/2009, Implementing Regulation (EU) No 725/2011 and the Technical Guidelines for the preparation of applications for the approval of innovative technologies pursuant to Regulation (EC) No 443/2009 and Regulation (EU) No 510/2011 (3). ---|--- (2) | The information provided in the application demonstrates that the conditions and the criteria referred to in Article 12 of Regulation (EC) No 443/2009 and in Articles 2 and 4 of Implementing Regulation (EU) No 725/2011 have been met. Moreover, the application is supported by a verification report established by an independent and certified body in accordance with Article 7 of that Regulation. As a consequence, the efficient generator function of the 12 V i-StARS belt-driven starter-alternator proposed by the applicant should be approved as an eco-innovation. ---|--- (3) | Based on the information provided with the current application and with Commission Implementing Decision (EU) 2016/265 (4), taking into account the experience gained from the assessment of applications concerning technologies that contribute to improving the efficiency of alternators in the framework of Commission Implementing Decisions 2013/341/EU (5), 2014/465/EU (6), (EU) 2015/158 (7), (EU) 2015/295 (8), (EU) 2015/2280 (9), and (EU) 2016/588 (10), it has been satisfactorily and conclusively demonstrated that a 12 V motor-generator that has a maximum mass of 7 kg and a minimum efficiency of the generator function meets the criteria referred to in Article 12(2)of Regulation (EC) No 443/2009 and provides a reduction in CO2 emissions of at least 1 g CO2/km in accordance with Article 9 of Implementing Regulation (EU) No 725/2011. For a 12 V motor generator that has a mass exceeding 7 kg, it is necessary to apply a mass correction coefficient when calculating if the 1 g CO2/km reduction threshold is met. ---|--- (4) | It is therefore appropriate to generally acknowledge and, in accordance with Article 12(4) of Regulation (EC) No 443/2009, attest the capacity of this innovative technology to reduce CO2 emissions and provide a generic testing methodology for the certification of the CO2 savings from the use of the generator function of efficient 12 V motor-generators. ---|--- (5) | The manufacturer should, in order to have the CO2 savings from efficient 12 V motor-generators certified, provide a verification report from an independent and certified body confirming the compliance of the motor-generator with the conditions specified in this Decision together with the application for certification to the type approval authority. ---|--- (6) | If the type approval authority finds that the motor-generator presented by the manufacturer does not satisfy the conditions for certification as specified in this Decision, the application for certification of the savings should be rejected. ---|--- (7) | It is appropriate to determine the reduction in CO2 emissions from efficient 12 V motor-generators using the testing methodology set out in the Annex. ---|--- (8) | In order to determine the CO2 savings it is necessary to define the baseline technology against which the efficiency of the efficient 12 V motor-generator should be compared as provided for in Articles 5 and 8 of Implementing Regulation (EU) No 725/2011. On the basis of the experience gained, it is appropriate to consider a 12 V alternator with 67 % efficiency as the baseline technology. ---|--- (9) | The savings from the efficient 12 V motor-generator may be partially demonstrated in the test referred to in Annex XII to Commission Regulation (EC) No 692/2008 (11). The final total savings for the purpose of the certification of a vehicle fitted with the innovative technology in accordance with Article 11 of Implementing Regulation (EU) No 725/2011 should therefore be determined in accordance with the second subparagraph of Article 8(2) of that Implementing Regulation. ---|--- (10) | In order to facilitate a wider deployment of efficient 12 V motor-generators in new vehicles, a manufacturer should also have the possibility to apply for the certification of the CO2 savings from several different 12 V motor-generators by a single certification application. It is however appropriate to ensure that where this possibility is used a mechanism is applied that incentivises the deployment of only those 12 V motor-generators that offer the highest efficiency. ---|--- (11) | For the purposes of determining the general eco-innovation code to be used in the relevant type approval documents in accordance with Annexes I, VIII and IX to Directive 2007/46/EC of the European Parliament and of the Council (12), the individual code to be used for the innovative technology should be specified, ---|--- HAS ADOPTED THIS DECISION: Article 1 Approval The efficient generator function of the 12 V motor-generator, i.e. of the i-STARS belt-driven starter-alternator, as described in the application by Valeo Electrical Systems, is approved as an innovative technology within the meaning of Article 12 of Regulation (EC) No 443/2009.

The manufacturer may apply for certification of the CO2 savings from one or several efficient 12 V motor-generators intended for use in conventional combustion-engine-powered M1 vehicles, provided that each motor-generator complies with the following conditions: (a) | where the mass of the efficient 12 V motor-generator does not exceed the mass of the baseline alternator of 7 kg and the efficiency of the generator function, determined in accordance with the Annex, is at least: | (i) | 73,8 % for petrol-fuelled vehicles; ---|--- (ii) | 73,4 % for petrol turbo-fuelled vehicles; ---|--- (iii) | 74,2 % for diesel-fuelled vehicles; ---|--- or, (b) | where the mass of the 12 V motor generator exceeds the mass of the baseline alternator as specified in point (a), the extra mass is taken into account in accordance with Formula 10 set out in the Annex and meets the minimum reduction threshold of 1 g CO2/km, specified in Article 9(1) of Implementing Regulation (EU) No 725/2011. The extra mass shall be verified and confirmed in the verification report to be submitted to the type approval authority together with the application for certifications. ---|--- 2\.
