EV fault diagnosis course — studying from the United Kingdom
The United Kingdom is building capability in electric vehicles, battery manufacturing and hydrogen technologies, driven by the national net zero strategy. Battery gigafactory projects, electric vehicle plants and research centres such as the Faraday Institution support growing demand for cell design, battery management and recycling expertise. Hydrogen projects in Teesside, Scotland and the North West explore production, storage and fuel cell applications. Engineers in these areas work with automotive manufacturers, energy companies and research bodies.
Fees for the United Kingdom: £455 (Pound sterling), with instalments and employer sponsorship available.

Questions from the United Kingdom
Which UK bodies are relevant to electromobility, battery and hydrogen engineering qualifications?
Relevant UK bodies include the Institution of Engineering and Technology (IET), the Institute of Materials, Minerals and Mining (IOM3), and the Institution of Mechanical Engineers (IMechE). Chartered registration is managed through the Engineering Council. SEIUM's qualifications are private and not accredited by these bodies, so confirm with the relevant institution how your study would be considered.
Are electromobility and battery skills in demand with UK employers, and do private qualifications count?
UK employers in electric vehicles, battery manufacturing, energy storage and hydrogen projects look for practical technical skills and relevant experience. A private qualification can demonstrate specialist knowledge, but employers decide how much to rely on it. Project evidence and hands-on competence are generally what carry the most weight.
Can I study this from the UK while working, and what should I check about time and funding?
Yes, programmes are fully online, so you can study from anywhere in the UK without a student visa. Teaching is in English, so good technical English is needed. An assigned technical tutor supports you throughout. Fees can be paid in instalments, and employer sponsorship may be possible depending on your employer. Check the hours involved against your working week.

How you'll learn
100% online training on the SEIUM campus, with downloadable materials, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within the intake, so you can combine it with work.
Each module combines theory, guided reading of the original standards and applied exercises. The working software is Vector CANalyzer, PicoScope, Autel MaxiSys, Bosch ESI[tronic] and Wireshark, in free, academic or evaluation versions. Exercises are based on real procedures: diagnosing an electric vehicle in the workshop, analysing BMS communication frames and measuring insulation in a high-voltage system. Assessment is continuous by module plus the final integrating project.
Standards covered: ISO 14229-1, ISO 6469-3, UN/ECE Regulation No 100, ISO 13400-2, ISO 15765-2, SAE J1979-2, Real Decreto 614/2001.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
