I would be happy to see that connection between batteries and USB connector on the schematics of some real device. How does it look like? Best regards, Krzysztof
Support for Battery Status & Battery Caps messages in response to Get_Battery_Status & Get_Battery_Cap request is required by USB PD devices powered by battery, as per "USB PD R3.1 V1.8 Spec", "6.13 Message Applicability" section. This patchset adds support for these AMSes to achieve greater compliance with the spec.
