3. TYPE I TEST METHODS
3.1. Externally chargeable (OVC HEV) without an operating mode switch
3.1.1. Two tests shall be performed under the following conditions:
Condition A
:
Test shall be carried out with a fully charged electrical energy/power storage device.
Condition B
:
Test shall be carried out with an electrical energy/power storage device in minimum state of charge (maximum discharge of capacity).
The profile of the state of charge (SOC) of the electrical energy/power storage device during different stages of the Type I test is given in Appendix 1.
3.1.2. Condition A
3.1.2.1. The procedure shall start with the discharge of the electrical energy/power storage device of the vehicle while driving (on the test track, on a chassis dynamometer, etc.):
(a) at a steady speed of 50 km/h until the fuel consuming engine of the HEV starts up;
(b) or, if a vehicle cannot reach a steady speed of 50 km/h without starting up the fuel consuming engine, the speed shall be reduced until the vehicle can run a lower steady speed where the fuel consuming engine does not start up for a defined time/distance (to be specified between technical service and manufacturer);
(c) or with manufacturer’s recommendation.
The fuel consuming engine shall be stopped within 10 seconds of it being automatically started.
3.1.2.2. Conditioning of vehicle
3.1.2.2.1.
For compression-ignition engined vehicles the Part Two cycle described in Table 2 (and Figure 3) of Annex 4a shall be used. Three consecutive cycles shall be driven according to paragraph 3.1.2.5.3 below.
3.1.2.2.2.
Vehicles fitted with positive-ignition engines shall be preconditioned with one Part One and two Part Two driving cycles according to paragraph 3.1.2.5.3 below.
3.1.2.3. After this preconditioning, and before testing, the vehicle shall be kept in a room in which the temperature remains relatively constant between 293 and 303 K (20 °C and 30 °C). This conditioning shall be carried out for at least 6 hours and continue until the engine oil temperature and coolant, if any, are within ± 2 K of the temperature of the room, and the electrical energy/power storage device is fully charged as a result of the charging prescribed in paragraph 3.1.2.4 below.
3.1.2.4. During soak, the electrical energy/power storage device shall be charged:
(a) with the on board charger if fitted; or
(b) with an external charger recommended by the manufacturer, using the normal overnight charging procedure.
This procedure excludes all types of special charges that could be automatically or manually initiated like, for instance, the equalisation charges or the servicing charges.
The manufacturer shall declare that during the test, a special charge procedure has not occurred.
3.1.2.5. Test procedure
3.1.2.5.1.
The vehicle shall be started up by the means provided for normal use to the driver. The first cycle starts on the initiation of the vehicle start-up procedure.
3.1.2.5.2.
The test procedures defined in either paragraph 3.1.2.5.2.1 or 3.1.2.5.2.2 may be used in line with the procedure chosen in Regulation No 101, Annex 8, paragraph 3.2.3.2.
3.1.2.5.2.1.
Sampling shall begin (BS) before or at the initiation of the vehicle start up procedure and end on conclusion of the final idling period in the extra-urban cycle (Part Two, end of sampling (ES)).
3.1.2.5.2.2.
