       METHOD FOR MEASURING THE ELECTRICITY BALANCE OF
       THE BATTERY OF OVC AND NOVC HEVS

         1. Introduction

         1.1. The purpose of this appendix is to define the method and required instrumentation for measuring the electricity balance of Off Vehicle Charging Hybrid Electric Vehicles (OVC HEV and Not Off Vehicle Charging Hybrid Electric Vehicles (NOVC HEVs). Measurement of the electricity balance is necessary

            (a) To determine when the minimum state of charge of the battery has been reached during the test procedure defined in paragraphs 3. and 4. of this annex; and

            (b) 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 3.2.3.2.2., 4.2.4.2.2., 5.3.4.1., 5.3.6.1., 6.3.4.1., and 6.3.6.1. of this annex.

         2. Measurement equipment and instrumentation

         2.1. During the tests as described in paragraphs 3., 4., 5. and 6. of
