Division 1 INTRODUCTION

In order to determine the CO₂ emission reductions that can be attributed to the use of the generation function of the SEG Automotive Germany GmbH High efficient 48V motor generator (BRM), hereinafter referred to as 48 V motor generator or motor generator, plus the 48V/12V DC/DC converter, for use in vehicles in compliance with the conditions set out in Article 1, it is necessary to specify the following:

1. (1)

   The test conditions;

2. (2)

   The test equipment;

3. (3)

   The procedure to determine the total efficiency;

4. (4)

   The procedure to determine the CO₂ savings;

5. (5)

   The procedure to determine the uncertainty of the CO₂ savings.

Two alternative methods can be used to determine the CO₂ savings. The methods are described as follows.
