The software-defined vehicle
A car as a computer you update: how it is wired, layered and regulated.
How a car turns from a few dozen boxes of fixed-function electronics into a computer you update: the architecture, the software stack, the networks, the services, the over-the-air pipeline and the standards that govern all of it. The picture is an illustration of the idea, not a real car.

EV charging
How a car and a charger talk, signal by signal.
How an electric vehicle and a charger agree on what to do, drawn from the standards: the circuits, the signals on the wire and the messages they exchange.

V2G and V2X
A car that gives energy back: which standard governs each link to the grid.
How a car can send energy back to a home, a building or the grid, explained from the standards: who controls what at each link of the chain, and which document governs it. “V2X” here means bidirectional charging, not vehicle-to-vehicle radio such as C-V2X or DSRC. The picture is an illustration of the idea, not a real car or charger.
