Outcome

What you will be able to do

Explain the difference between AC and DC charging and where conversion happens; calculate charging times and currents; describe the control pilot and proximity pilot and the Type 2 and CCS2 connectors; explain what BS 7671 Section 722 and the IET Code of Practice ask of an EV installation, including earthing on PME supplies; describe the Electric Vehicles (Smart Charge Points) Regulations 2021 and the Public Charge Point Regulations 2023; describe OCPP and OCPI; plan a charging site from DNO connection to commissioning tests; and work out the payback of a charger from utilisation and margin.

EDWartens Lab

Practise this in the EDWartens Lab

Test a solar string, isolate the DC side safely and find an EV charger fault in the Lab's Solar and EV simulator.

Works alongside EV Charging Infrastructure: AC, DC, CCS2 and Charging Stations. The Lab is solar and ev charging practice in your browser: no install, no hardware, free to use. Sign in as a learner and it opens with your account.

Levels to try with this course

Optional. Skip it whenever you like: it never blocks your progress or your certificate.

Why practise in a lab

Technical work is judged on what you can do: wiring, commissioning, finding a fault. Doing a task yourself teaches more than watching it a second time, and a lab lets you try it safely before you meet real equipment. It does not replace working on real hardware.

  • Practise safely, so a mistake costs nothing.
  • The lab checks your work like a site test, so you know when it is right.
  • Free, in your browser, with nothing to install.

Certificate

Questions

About this course

Who is this course for?
Electricians, electrical engineers, site engineers and technicians moving into EV charging in Britain, and anyone planning or running charging sites. Basic electrical theory is assumed.
Where do the lessons come from?
From short videos by UK installers and industry channels such as eFIXX, The Regs Guy, myenergi and Zapmap, credited on each module. EDWartens is not affiliated with any of them and wrote the notes, practice, project and assessment.
Do I need power electronics?
No. The course explains AC and DC chargers at the block level.
Which regulations and standards does it cover?
BS 7671 Section 722 and the IET Code of Practice for EV charging equipment installation, including PME earthing and open-PEN protection; the Type 2 and CCS2 connectors; the Electric Vehicles (Smart Charge Points) Regulations 2021; the Public Charge Point Regulations 2023; OCPP and OCPI; and the DNO connection process. It gives a brief international note on battery swapping. Standards are paraphrased, and you should always check current editions before working on a real installation.
How long does the course take?
About 3.5 hours of video lessons across eight teaching modules, or about 9 hours with the notes, practice questions and final assessment. At a few hours a week it fits into three to four weeks.
Is the course really free?
Yes. Every module, the notes, the project and the final assessment. The only paid item is the certificate, if you want it.
What certificate do I get?
An EDWartens Certificate of Completion, issued when you finish every module and pass the final assessment at 60 percent, with a number anyone can verify on our site. It is not an installer registration or a competent person scheme membership.
Does it lead to a job?
It gives you the knowledge behind EV charge point work, but no course can promise a job. Installing charge points needs competence and, usually, membership of a registered scheme, which the course does not provide.

The Professional Module is five live days of Siemens PLC, HMI and SCADA with an instructor, then a resume session and a CPD certificate.
