Naw, no polling, just separate events for separate things, e.g.,

- charger N inserted
- charger M removed
- battery X started charging
- battery Y is full now
- battery Z has caught fire
etc.

It's probably also a lot easier to debug the state machine that
disambiguates the various events in user space, e.g., you may well
get a "battery is full" event moments after the charger has been
removed.
