§ 1066.501 Overview.
Use the following procedures to test EVs and HEVs (including PHEVs):
(a) Correct the results for Net Energy Change of the RESS as follows:
(1) For all sizes of EVs, follow SAE J1634 (incorporated by reference in § 1066.1010).
(2) For HEVs at or below 14,000 pounds GVWR, follow SAE J1711 (incorporated by reference in § 1066.1010) except as described in this paragraph (a). Disregard provisions of SAE J1711 that differ from this part or the standard-setting part if they are not specific to HEVs. Apply the following adjustments and clarifications to SAE J1711:
(i) If the procedure calls for charge-sustaining operation, start the drive with a State of Charge that is appropriate to ensure charge-sustaining operation for the duration of the drive. Take steps other than emission measurements to confirm that vehicles are in charge-sustaining mode for the duration of the drive.
