Sorry, I kind of jumped the gun on this. I looked through the Google search results more thoroughly this morning and discovered that AC0, AC1, and BAT are also common names.
If any of you would like to help, could you look in /sys/class/power_supply on your computer and let me know if your devices have other names that I missed?

This matches my amd64 hardware.
My armv7l chromebook reports the battery as: "sbs-20-000b" (alongside "gpio-charger") My aarch64 pinebook reports the battery as: "battery" (alongside "ac" and "usb")
On my system /sys/class/power_supply/*/type file contains either "Mains" for AC device, or "Battery" for BAT0.
I haven't checked kernel sources to see if it makes sense to rely on these values, hopefully it doesn't depend on the driver. If it's relatively stable, maybe we could look for type instead of the device name?
