The adaptive battery charging optimization system (100) comprises a battery module (104), an input acquisition module (106), an action profile generator (108), a relative time sequencer (110), a battery digital twin module (112), a state estimation module (114), a reward transformation module (116), a reward aggregation module (118), a comparison module (120), and an action selector module (122). The battery module (104) is configured to provide initial operational parameters. The input acquisition module (106) is configured to receive the operational parameters and output a pre-processed parameter set. The action profile generator (108) is configured to generate a plurality of charging current profiles. The relative time sequencer (110) is configured to generate a relative time sequence associated with each charging profile. The battery digital twin module (112) is configured to simulate time-dependent battery behaviour to generate a simulation output for each profile. Figure. 1
