for the state of charge drops by one scale or 10%, record the current distance traveled. When
the vehicle issues a warning for the state of charge, record the distance traveled Dconstant-speed 1.
5.6.2.7 For vehicles with the limping function (such as: speed limit and power limit driving),
the limp distance can continue to be measured after the test in 5.6.2.3. The limp distance will
not be included in the range and range of warning for the state of charge, but additional
explanations may be provided in the test record.
