What you’ll learn

From grid to batteryTrace how electricity moves from the grid through AC or DC charging equipment into an electric vehicle battery.Charging is a negotiated electrical path, and the connector, EVSE, and conversion hardware determine how energy reaches the battery.
Power, batteries, and limitsUse kilowatts, battery state, and component ratings to explain why charging power changes during a session.Power is a rate, while the vehicle, battery, cable, station, and grid together set the practical charging ceiling.
Charging in place and timeMatch home, public, managed, solar-assisted, and cable-connected charging to the time and power available.Charging works as a system of locations, dwell times, shared loads, controls, and physical equipment.
Use the systemDiagnose a slow session, plan a useful stop, and distinguish the equipment and grid terms used to describe charging.Good charging decisions start with the next trip and identify the actual limit instead of trusting a single label or peak number.

Questions this course answers

Where is AC usually converted for an AC charging session?

The onboard charger converts incoming AC to DC for the battery.

What does a kilowatt measure?

Kilowatts describe power, while kilowatt-hours describe energy.

Why can a 350-kilowatt station charge a car more slowly?

The lowest-rated vehicle, cable, station, or grid component sets the practical ceiling.

What does managed charging try to change?

Managed charging shifts schedules or power to meet energy and grid objectives.

What usually happens near a high battery state of charge?

Battery controls commonly reduce current as cells approach their voltage limits.
