EVs add flexible load and storage; chargers need power electronics and standards.
EVs use batteries, inverters and motors; AC charging uses an onboard charger, DC fast charging bypasses it. Standards: CCS, CHAdeMO, Type 2. Smart charging and V2G shift load. Charging at 350 kW needs high-power grid connections.
A 60 kWh car charged at 7 kW takes about 9 hours.
Electric vehicles add a large flexible load and a mobile battery, so charging design affects both grid planning and vehicle performance.

Electric vehicles add a large flexible load and a mobile battery, so charging design affects both grid planning and vehicle performance.
Level 1 is a standard outlet, Level 2 is a higher-power AC charger, and DC fast charging supplies high power directly to the battery.
The battery's chemistry and temperature set the maximum charge current, so a charger cannot always deliver its rated power.
Typical applications include planning the charger capacity for a car park with many EVs, designing a home charger that uses off-peak power and using vehicle-to-grid to support the grid at peak times.
Study "Microgrids" first (topic 85 of 106 in Electrical Engineering). It covers the groundwork this topic builds on.
kWh per 100 km. Charging curve tapering. Battery thermal management.
A 60 kWh car charged at 7 kW takes about 9 hours.
The next topic is "Power electronics converters", which builds directly on this one.
It is classed as Advanced in Electrical Engineering (topic 86 of 106). It is an advanced topic. It assumes you are comfortable with the intermediate topics in Electrical Engineering.
