How you'll learn
100% online training on the SEIUM Institute campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so you can combine it with full-time work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Vector CANoe, Wireshark, Keysight Scienlab Charging Discovery System and Josev, in free, academic or evaluation versions. Exercises are based on real procedures: diagnosing an incompatibility between a vehicle and a CCS charger, comparative analysis of CHAdeMO and GB/T sessions and a test plan for a multi-standard charger.
Assessment is continuous, module by module, plus the final project.
Standards covered: IEC 62196-3; IEC 61851-23; IEC 61851-24; DIN SPEC 70121; ISO 15118-2; GB/T 27930; GB/T 20234.3; SAE J3400.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.

Frequently asked questions
The programme totals 300 hours over 3 months. You set your own pace within each intake, and your tutor helps you plan the workload around your job.
You work with Vector CANoe, Wireshark, Keysight Scienlab Charging Discovery System and Josev, using free, academic or evaluation versions. Your tutor indicates the free alternative wherever one exists.
A SEIUM Institute certificate, awarded on passing the continuous assessment and the final project. It is SEIUM's own qualification, not an official state degree; its recognition depends on the programme completed and the regulations of each country.
Yes. Modules passed are recognised in a higher programme in the same area (postgraduate diploma or master's). Ask about the recognition policy when you enrol.
No prior qualification is required: you only need an internet connection, a computer able to run the programme's software and English sufficient to read technical standards.
Start dates are set by SEIUM's faculty for each intake. Our admissions team will confirm the next available date when you apply.
