Annex B8 – Appendix 4 Preconditioning, soaking and REESS charging conditions of PEVs, OVC-HEVs and OVC-FCHVs (as applicable) 1.
This appendix describes the test procedure for REESS and combustion engine preconditioning in preparation for: (a) Electric range, charge-depleting and charge-sustaining measurements when testing OVC-HEVs and OVC-FCHVs; and (b) Electric range measurements as well as electric energy consumption measurements when testing PEVs.

OVC-HEV and OVC-FCHV preconditioning and soaking
2.1.
Preconditioning and soaking when the test procedure starts with a charge-sustaining test
2.1.1.
For preconditioning the combustion engine, the vehicle shall be driven over at least one applicable WLTP test cycle.
During each driven preconditioning cycle, the charging balance of the REESS shall be determined.
The preconditioning shall be stopped at the end of the applicable WLTP test cycle during which the break-off criterion is fulfilled according to paragraph 3.2.4.5. of this annex.
2.1.2.
As an alternative to paragraph 2.1.1. of this appendix, at the request of the manufacturer and upon approval of the responsible authority, the state of charge of the REESS for the charge-sustaining Type 1 test may be set according to the manufacturer’s recommendation in order to achieve a test under charge-sustaining operating condition.
In such a case, a preconditioning procedure, such as that applicable to pure ICE vehicles as described in paragraph 2.6. of Annex B6, shall be applied.
2.1.3.
Soaking of the vehicle shall be performed according to paragraph 2.7. of Annex B6.
2.2.
Preconditioning and soaking when the test procedure starts with a charge-depleting test
2.2.1.
OVC-HEVs and OVC-FCHVs shall be driven over at least one applicable WLTP test cycle.
During each driven preconditioning cycle, the charging balance of the REESS shall be determined.
The preconditioning shall be stopped at the end of the applicable WLTP test cycle during which the break-off criterion is fulfilled according to paragraph 3.2.4.5. of this annex.
2.2.2.
Soaking of the vehicle shall be performed according to paragraph 2.7. of Annex B6.
Forced cooling down shall not be applied to vehicles preconditioned for the Type 1 test.
During soak, the REESS shall be charged using the normal charging procedure as defined in paragraph 2.2.3. of this appendix.
2.2.3.
Application of a normal charge
Normal charging is the transfer of electricity to an electrified vehicle with a power of less than or equal to 22 kW.
Where there are several possible methods to perform a normal AC charge (e.g. cable, induction, etc.), the charging procedure via cable shall be used.
Where there are several AC charging power levels available, the highest normal charging power shall be used.
An AC charging power lower than the highest normal AC charging power may be selected if recommended by the manufacturer and by approval of the responsible authority.
