for the fuel consumption values measured over the Part One cycle and the Part Two cycle respectively.

       6.3.6. CO2-emission at zero battery energy balance (M0)

       6.3.6.1. The CO2-emission M0 at Ebatt = 0 is determined by the following equation:

       M0 = M – KCO2·Q           (g/km)

        where:

         C: fuel consumption measured during test (l/100 km)

         Q: electricity balance measured during test (Ah)

       6.3.6.2. CO2-emission at zero battery energy balance shall be determined separately for the CO2-emission values measured over the Part One cycle and the Part Two cycle respectively.

       METHOD FOR MEASURING THE ELECTRICITY BALANCE OF
       THE BATTERY OF A NOVC HEV

     1. Introduction

     1.1. The purpose of this appendix is to define the method and required instrumentation for measuring the electricity balance of Not Off Vehicle Charging Hybrid Electric Vehicles (NOVC HEVs).  Measurement of the electricity balance is necessary to correct the measured fuel consumption and CO2-emissions for the change in battery energy content occurring during the test, using the method defined in paragraphs 5. and 6. of this annex.

     1.2. The method described in this annex shall be used by the manufacturer for the measurements that are performed to determine the correction factors Kfuel and KCO2, as defined in paragraphs 5.3.3.2., 5.3.5.2., 6.3.3.2., and 6.3.5.2. of this annex.

      The Technical Service shall check whether these measurements have been performed in accordance with the procedure described in this annex.

     1.3. The method described in this annex shall be used by the Technical Service for the measurement of the electricity balance Q, as defined in paragraphs
