Differentiation between electric vehicles

Voltage classes

Another characteristic for differentiating electric vehicles is the voltage classes. Among other things, working methods and safety regulations for the workshop can be derived from this. The table below shows how many different voltage classes exist and how they differ. The differences between a partially electric and a fully electric vehicle are particularly striking.

Capacity ratio max./ duration

Speed ratio EM / crankshaft or max. speed EM

DC voltage min. (motor)

DC voltage max. (gen- erator)

max. EM motor torque

max. EM motor capacity

max. cur- rent DC

max. cur- rent AC
