EV Charging Infrastructure: AC, DC, CCS2 and Charging Stations
How EV charging actually works, from the grid to the battery: AC and DC chargers and what is inside them, Type-2 and CCS2, the control pilot, OCPP, public charging stations, battery swapping, and the economics of a charging business. Built on NPTEL lectures from IIT Madras and IIT Roorkee.

The course project 路 about 8 hours
Planning a highway fast-charging hub at a fuel station: load list, site design basis, risk register and business case
Plan an EV charging hub at a highway fuel station as the project engineer: build the load list for the charger mix, write the site design basis from grid connection to OCPP back-end, build the safety and operational risk register, and prepare the business case with utilisation and payback. The sample pack shows each document for a fuel station on the Nairobi to Nakuru highway near Naivasha, Kenya.
Sample document pack, 4 documents, filled in for the scenario

- PlanSite design basis: Naivasha highway charging hub
- Risk registerRisk register: Naivasha highway charging hub
- ReportBusiness case: Naivasha highway charging hub

A shareable EDWartens certificate
Finish every module and pass the final assessment, and the optional EDWartens certificate is yours. It carries a unique verification code on a public page anyone can check, so it stands up when a recruiter looks it up. See it below.
The course itself stays free whether or not you ever buy one.
Stuck? Ask a practising engineer
A free course usually means a comment section and hope. This one does not. Every module has an Ask-your-trainer panel that reaches the same engineers who teach our paid programme: people who commission panels for a living, not moderators.
Pairs well with
PLC programming 路 FreeSiemens TIA PortalFrom zero electrical knowledge to a working, simulated S7-1200 program, for nothing.
PLC programming 路 FreeSiemens TIA Portal in Three HoursThe first three hours of the Siemens TIA Portal course, cut to end on a win: what a PLC is, how it is wired, a project configured in TIA Portal, and your first ladder program running in simulation. Finish it in an evening or two, earn a certificate, and carry straight on into the full course.
PLC programming 路 FreeTIA Portal: Build a MachineOne machine, start to finish. Take a bottle filling line from a written specification and an I/O list to a structured S7-1200 program with a fill station, a capper, a reject sorter and an operator screen with alarms, then test it against a written record and archive it for hand-over. The lessons are the reference; the machine is yours, and it is what you submit.
Instrumentation 路 FreeInstrumentation for PLC EngineersThe half of the loop that is not code. Follow one measurement from the transmitter in the field, down the 4-20 mA loop, into the analog card, through NORM_X and SCALE_X into engineering units, out again to a valve, and back to the control room when the reading is wrong.More free courses: Free electric vehicle courses

Common questions
Who is the EV Charging Infrastructure course for?
Electrical engineers, site engineers and technicians moving into EV charging, and anyone planning or running charging sites. Basic electrical theory is assumed.
Is this an NPTEL course?
No. It is built on NPTEL's free public lectures from IIT Madras and IIT Roorkee, credited on each module, but it is not the NPTEL programme and is not affiliated with NPTEL or the IITs. EDWartens wrote the notes, practice, project and assessment.
Do I need power electronics?
No. The course explains AC and DC chargers at the block level. The full IIT Roorkee lectures go deeper if you want to.
Which countries' standards does it cover?
Mainly the international ones: IEC 61851 and the Type 2 and CCS2 connectors used across Europe and much of the world. India is the worked national example, with its IS 17017 adoption of IEC 61851, the earlier Bharat AC-001 and DC-001 standards and the Ministry of Power's 2024 charging guidelines.
How long does the EV Charging Infrastructure course take?
About 9.3 hours of video lessons across eight teaching modules, plus the notes, practice questions, the final assessment and an optional project of around 8 hours. At a few hours a week it fits into three to four weeks.
What is the project in the EV Charging Infrastructure course?
You plan a fast-charging hub at a fuel station on a busy intercity highway: the load list and charger mix, the site design basis from grid connection to OCPP, a risk register and a business case with payback. A worked sample pack shows each document.
Is the EV Charging Infrastructure 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 does the EV Charging Infrastructure course give?
An EDWartens Certificate of Completion, issued when you pass the final assessment, with a number anyone can verify on our site.
