Unfortunately that does not work
"sudo flasher -i" just reads and displays the device version, it does not start charging the device.
You need to inject the APE kernel to the device to make it start charging, and the easiest way to do that is to push it to the device by "sudo flasher -F main.bin -f" command...

There are alternatives, actually it would not be necessary to initiate flashing, just to push APE in and make it happy to keep up the connection, which by default means the flasher program stays active on the computer.

I actually made a special bootkernel that does the same thing without requiring the aid of flasher by ripping the rootFS out of APE and beating it into the right form

(my intention here is to integrate ithe BME charging logic into ubiboot, but unfortunately I have not had time to complete that yet...)
