The ambient temperature and the SOC shall be in accordance with the said Regulations. This requirement is deemed to be met if the vehicle equipped with electric power train operating on high voltage is approved in accordance with UN Regulation No. 94 (04 series of amendments or later) or UN Regulation No. 137 (01 02 series of amendments or later) for frontal impact and UN Regulation No. 95 (05 series of amendments or later) for lateral impact.

Reasons

  • Proposer's reason (informal document GRSP-70-26)

    The old text referred correctly to the 04 series of UN R94 and the 05 series of UN R95. It referred to the 01 series of UN R137 by error, instead of the 02 series. The 02 series of UN R137 introduced updated electrical safety requirements.

    Submitted by The experts of OICA. Working party adoption: ECE/TRANS/WP.29/GRSP/70, para. 17.
