4.6.3.5 LV123
LV123 has been compiled for the electrical characteristics of new energy ve-
hicles for major European car manufacturers. For its high-voltage system parts,
the state standard within its operating voltage range is defined. The relevant pa-
rameters are introduced as follows:
Please pay attention to whether the voltage value defined in the LV123
standard matches the rated voltage of the instrument, otherwise some
waveforms cannot be recalled.
