1. The user initiates a charge session request (black lines).
2. The EVSE verifies the status of the EV (purple lines).
3. The EVSE goes on and AC power goes to the EV (yellow lines).
4. The charge session starts. AC power flows from the power grid to the
EV (red lines).
5. The electrical interfaces of the EVSE communicate with the on-board
computer (blue lines).
(*): Connections between parts of the EVSE and the CPU system. The arrow
shows the direction of the input and output signals.
