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
