Common use of Component based test Clause in Contracts

Component based test. 5.2.1. REESS preparation The ageing of REESS shall be checked, to confirm that the REESS has performed at least 5 standard cycles (as specified in Annex 8, Appendix 1). 5.2.2. Discharge of the REESS The REESS is discharged at 70 per cent ± 5 per cent of the nominal power of the system. Stopping the discharge occurs when minimum SOC as specified by the manufacturer is reached. 5.2.3. Soak Within 15 minutes of the end of the REESS discharge operation specified in paragraph 5.2.2. above, and before the start of the hydrogen emission test, the REESS shall be soaked at 293 K ± 2 K for a minimum period of 12 hours and a maximum of period of 36 hours. 5.2.4. Hydrogen emission test during a normal charge 5.2.4.1. Before the completion of the REESS's soak period, the measuring chamber shall be purged for several minutes until a stable hydrogen background is obtained. The enclosure mixing fan(s) shall also be turned on at this time. 5.2.4.2. The hydrogen analyser shall be zeroed and spanned immediately prior to the test. 5.2.4.3. At the end of the soak period, the REESS shall be moved into the measuring chamber. 5.2.4.4. The REESS shall be charged in accordance with the normal charge procedure as specified in paragraph 5.2.4.7. below. 5.2.4.5. The chamber shall be closed and sealed gas-tight within two minutes of the electrical interlock of the normal charge step. 5.2.4.6. The start of a normal charge for hydrogen emission test period shall begin when the chamber is sealed. The hydrogen concentration, temperature and barometric pressure are measured to give the initial readings CH2i, Ti and Pi for the normal charge test. These figures are used in the hydrogen emission calculation (paragraph 6. of this annex). The ambient enclosure temperature T shall not be less than 291 K and no more than 295 K during the normal charge period. 5.2.4.7. Procedure of normal charge The normal charge is carried out with a suitable charger and consists of the following steps: (a) Charging at constant power during t1;

The ambient enclosure temperature T shall not be less than 291 K and no more than 295 K during the normal charge period. 5.2.4.7. Procedure of normal charge The normal charge is carried out with a suitable charger and consists of the following steps: (a) Charging at constant power during t1; (a) Over-charging at constant current during t2. Over-charging intensity is specified by manufacturer and corresponding to that used during equalisation charging. The end of REESS charge criteria corresponds to an automatic stop given by the charger to a charging time of t1 + t2. This charging time will be limited to t1 + 5 h, even if a clear indication is given by a suitable instrumentation that the REESS is not yet fully charged. 5.2.4.8. The hydrogen analyser shall be zeroed and spanned immediately before the end of the test. 5.2.4.9. The end of the emission sampling period occurs t1 + t2 or t1 + 5 h after the beginning of the initial sampling, as specified in paragraph 5.
