Methods and systems for bi-directional converter based battery module control for a vehicle electrical system are provided. The method includes monitoring a plurality of Smart Charging Modules (SCMs). Each of the plurality of SCMs can include a bi-directional converter and a plurality of electric switches. Each of the plurality of electric switches can connect to and control a battery module. The method also includes monitoring a load from the vehicle electrical system. The method further includes determining an operational mode for each of the plurality of SCMs. Also the method includes determining a synchronization pattern for the plurality of SCMs. The synchronization pattern is a pattern for phasing current draws such that a current draw for each of the plurality of SCMs does not overlap with each other. Further the method includes the plurality of SCMs directing power to the load based on the synchronization pattern.
