Bidirectional EV Charger Prototype
Build smart EV charging circuit with grid integration. Implement charging algorithm, power factor correction, vehicle communication protocol.
Safety: Involves mains/AC or high-current power. Work only under instructor supervision, use proper isolation, fusing, and PPE. Prefer low-voltage or simulated sources where possible.

Steps
- Define a low-voltage version of the charger and draw the power stage and control block diagram.
- Build the MOSFET switching stage with the IR2110 gate driver on the STM32 board.
- Program a charging algorithm with a constant current stage followed by a constant voltage stage.
- Add basic communication between the charger and a simulated vehicle using a simple message protocol.
- Test charging and reverse power flow, and measure power factor and efficiency.
- Document the design, safety measures, and test results for your portfolio.
