Volvo XC60 Alternator Control - Brake Energy Regeneration

[Wardair]

I am looking for information on when the 'Brake Energy Regeneration Mode' was introduced to the XC60 Alternator Control and what models this function is operative on and can it be switched on/off with VIDA?
My current understanding is that from 2010 Volvo introduced a Battery Monitoring Sensor and this is used to check Battery SoC and on some vehicles when the battery is above a certain percentage the Alternator Control changes from 'Conventional Charging' to 'Brake Energy Regeneration, Quick' (in daytime only) 'Brake Energy Regeneration, Slow No Discharge' is the mode used during the night.
Can anyone provide a link to further technical information on this feature?

Still reading and learning. My concern with this is there is a large discharge on acceleration which looks like the Alternator is used as a motor to assist engine, is this true?

Here is a great video showing the function in action:-
