A system for control of a battery system includes a processor connected to the battery system and configured to perform, in real time during a charging process, acquiring a set of charging parameter measurements, estimating a dynamic performance variable related to an electrochemical phenomenon occurring within the battery system during the charging process, and selecting a stored charging profile from a stored relation based on the charging parameter measurements. The processor is further configured to perform applying a charging current to the battery system based on the selected stored charging profile, inputting the charging parameter measurements, the stored charging profile and the stored relation to a learning agent, and evaluating the stored charging profile according to a reward-based learning process, the learning process including estimating a performance value associated with the stored charging profile. The processor is configured to periodically update the stored charging profile based on the learning process.
