AI in EV Charging and Vehicle-Grid Integration Quiz

Answers and explanations appear as you take the quiz.

1. What does smart or managed charging (V1G) mean?
   • Letting the car's battery discharge power back into the grid
   • Controlling the timing and rate of one-way charging
   • Charging only at high-power public fast chargers
   • Charging the car wirelessly through a pad in the ground
2. Which protocol lets a central management system control chargers from many different vendors?
   • ISO 15118
   • OpenADR
   • OCPP (Open Charge Point Protocol)
   • IFC
3. According to the guide, why are most deployments today smart one-way charging rather than V2G?
   • V2G is banned in most countries
   • One-way charging always saves drivers more money
   • Cars cannot measure their own battery level
   • Bidirectional charging needs compatible cars and chargers, interconnection approval and warranty coverage
4. What makes EV charging unusually well suited to flexible scheduling?
   • Cars often stay plugged in much longer than they need to charge
   • EV batteries charge fastest at night
   • Chargers can store energy themselves
   • Electricity prices never change overnight
5. What does it mean that smart-charging engines work on a rolling horizon?
   • They plan charging once a week and never update it
   • They let drivers roll back to manual charging
   • They re-solve the schedule frequently, often every 5 to 15 minutes, as new data arrives
   • They charge each car in turn, one after another
6. In a typical smart-charging system, what role does machine learning mainly play?
   • It replaces the optimization solver entirely
   • It predicts inputs such as dwell time and energy need, which feed the solver
   • It sets electricity tariffs for the utility
   • It controls the car's battery chemistry
7. What does the guide say about battery wear from V2G?
   • It always destroys the battery within a year
   • It has been proven to have no effect at all
   • It affects only the charger, not the car
   • It is not settled and depends on how deeply and how often the battery is cycled
8. What is aggregation in the context of EV charging?
   • Pooling many vehicles into a virtual power plant that bids flexibility into demand-response programs
   • Combining several chargers into one physical unit
   • Adding up a driver's monthly charging bill
   • Merging car and charger firmware updates
