Is there a way or suggestion to some works that can give me some informations how the signals of the battery in the BMS are estimated especially the actual maximal capacity of the battery in Ah (in order to supervise the aging of the battery).
The signals I have:
actual SoC [%]
actual energy in the battery or power capacity [Wh]
current [A]
voltage [V]
Many thanks in advance
check out papers on online estimation of battery life or health.
one of your indicators is the battery's internal resistance
here are some papers titles:

If you have already the estimasi SOC from your BMS, and the assumption the battery pack is in good / initial condition.
You just have to search the initial ampere hour of your battery pack, and calculate
the actual battery capacity from the SOC signal from BMS.
Ah(actual capacity) = SOCsignal x Ah(initial / full capacity).
Irsyad Nashirul Haq thank for your reply.
What I need is the actual maximal capacity in order to supervise the health of the battery.
