1 Scope

This Standard specifies the special safety specifications for Type M1 hybrid electric vehicles (for the definition of the hybrid electric vehicles, SEE GB/T 19596). This Standard is applicable to the Type M hybrid electric vehicles whose on- board circuits’ maximum operating voltage is less than 660V (AC) or 1,000V (DC) (according to the provisions of GB 156-1993). Other types of hybrid electric vehicles can use this Standard for reference.
