I am not participating in any W3C group so this might or might have been
discussed but this specification seems to be over simplified, specially if you
compare it what is provided by the power supply class of the Linux kernel[1].

What happens if you have more than one battery? Many modern devices have
backup batteries, e.g. to keep the RTC. What is the upgrade path for this
event to support applications that want to have a more detailed view (e.g. a
dashboard in a server farm that also wants to query the UPS)?

sorry for my two cents
