COMMISSION IMPLEMENTING DECISION (EU) 2022/252

of 21 February 2022

amending Implementing Decision (EU) 2020/1167 in order to specify the testing requirements to be applied to a 48 Volt efficient motor generator integrated in the transmission housing and combined with a 48 Volt/12 Volt DC/DC converter

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EU) 2019/631 of the European Parliament and of the Council of 17 April 2019 setting CO2 emission performance standards for new passenger cars and for new light commercial vehicles, and repealing Regulations (EC) No 443/2009 and (EU) No 510/2011 (1), and, in particular, Article 11(4) thereof,

Whereas:

| (1) | On 24 May 2021, the supplier ZF Friedrichshafen AG (‘the Applicant’) submitted an application for the approval, as an innovative technology, of a technology used in a 48 Volt efficient motor-generator with a 48 Volt/12 Volt DC/DC converter for use in certain not-off vehicle charging hybrid electric passenger cars and light commercial vehicles (NOVC-HEVs). |

On 24 May 2021, the supplier ZF Friedrichshafen AG (‘the Applicant’) submitted an application for the approval, as an innovative technology, of a technology used in a 48 Volt efficient motor-generator with a 48 Volt/12 Volt DC/DC converter for use in certain not-off vehicle charging hybrid electric passenger cars and light commercial vehicles (NOVC-HEVs).

| (2) | The technology used in 48 Volt efficient motor-generators with a 48 Volt/12 Volt DC/DC converter for use in the same type of NOVC-HEVs as referred to by the Applicant, has been approved as an innovative technology pursuant to Regulation (EU) 2019/631 by Commission Implementing Decision (EU) 2020/1167 (2). |
| --- | --- |

(2)

The technology used in 48 Volt efficient motor-generators with a 48 Volt/12 Volt DC/DC converter for use in the same type of NOVC-HEVs as referred to by the Applicant, has been approved as an innovative technology pursuant to Regulation (EU) 2019/631 by Commission Implementing Decision (EU) 2020/1167 (2).

| (3) | The technology specified by the Applicant in its application is a motor-generator that is directly connected to the transmission input shaft, i.e. an ‘integrated starter generator’, which allows reducing the mechanical losses occurring between the drive source and the generator. It operates only in the engine speed range of the internal combustion engine. |

It operates only in the engine speed range of the internal combustion engine.

| (4) | The technology specified by the Applicant has been found to deliver a high level of efficiency, and should be considered providing the same functionality as that approved by Implementing Decision (EU) 2020/1167. It should therefore be considered as an innovative technology to which the eco-innovation code 32 can be applied. |
