1.   Purpose

1.1.   The purpose of this sub-appendix is to describe 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 HEV).

2.   Measurement equipment and instrumentation

2.1.   During the tests as described in points 3.1 to 3.4 the battery current shall be measured using a current transducer of the clamp-on type or the closed type. The current transducer (i.e. the current sensor without data acquisition equipment) shall have a minimum accuracy of 0,5 % of the measured value or 0,1 % of the maximum value of the scale.

OEM diagnostic testers are not to be used for the purpose of this test.

2.1.1.   The current transducer shall be fitted on one of the wires directly connected to the battery. In order to easily measure battery current using external measuring equipment, manufacturers shall, if possible, integrate appropriate, safe and accessible connection points in the vehicle. If that is not feasible, the manufacturer is obliged to support the Technical Service by providing the means to connect a current transducer to the wires connected to the battery in the above described manner.

2.1.2.   The output of the current transducer shall be sampled with a minimum sample frequency of 5 Hz. The measured current shall be integrated over time, yielding the measured value of Q, expressed in Ampere hours (Ah).

2.1.3.   The temperature at the location of the sensor shall be measured and sampled with the same sample frequency as the current, so that this value can be used for possible compensation of the drift of current transducers and, if applicable, the voltage transducer used to convert the output of the current transducer.

2.2.   A list of the instrumentation (manufacturer, model no., serial no.) used by the manufacturer for determining when the minimum state of charge of the battery as been reached during the test procedure defined in points 3.1 and 3.2 and the last calibration dates of the instruments (where applicable) shall be provided to the Technical Service.

3.   Measurement procedure

3.1.   Measurement of the battery current shall start at the same time as the test starts and shall end immediately after the vehicle has driven the complete driving cycle.
