How to use this quiz
Take it cold, then look up anything you got wrong. The point isn’t the score — it’s finding the gaps.
Each question reveals the correct answer with an explanation as soon as you check answers. If you want to go deeper on any topic, the explanations link out to relevant articles where they exist.
What this quiz covers
This is the fundamentals quiz — concepts that everyone working in or around EV charging should know. It deliberately stays out of the protocol weeds (no OCPI, OCPP, ISO 15118 deep questions here). Those have their own quizzes.
Topics covered:
- Power (kW) vs energy (kWh)
- AC vs DC charging
- Level 1, Level 2, and DC Fast Charging
- Connector types (J1772, Type 2, CCS, CHAdeMO, NACS)
- State-of-charge tapering
- Onboard chargers
- Plug & Charge
If you scored 8+ out of 10, you have the basics. If you scored under 6, the “EV Charging Fundamentals” course (coming soon) is built for exactly this gap.
