Training duration for Level 2S/2E varies by entry path (A, B or C) – automotive technicians with electrical knowledge need significantly fewer teaching units than career changers.
The right HV training depends on what your employees actually do near the vehicle – not on company size.
The duration of an HV training course for Level 2S depends on your existing qualifications. DGUV 209-093 defines three entry paths – from 2 days to 2 weeks.
No electrical or automotive prior qualification. Level 2S in at least 80 teaching units (approx. 2 weeks), Level 2E in ≥ 100 teaching units.
More on Entry Path A →Kfz-Elektriker, Kfz-Mechatroniker (graduated before 2013), Kfz-Mechaniker. Level 2S in just 16 teaching units (approx. 2 days).
More on Entry Path B →Electricians, electronics technicians, electrical engineers without automotive background. Level 2S individually assessed, Level 2E in ≥ 24 teaching units.
