Programmable battery source architecture and method thereof

A programmable battery source architecture includes a battery module including a plurality of battery units, and a programmable battery connection circuit, coupled to the battery module. The programmable battery connection circuit includes: a matrix intersection line module, electrically coupling to the battery module for forming a plurality of battery connection configurations; a switch group disposed at each line intersection of the matrix intersection line module, for switching the battery connection configurations; and a control unit, for dynamically controlling the switch group based on a load requirement, for selecting at least a battery connection configuration from the battery connection configurations, and accordingly, the battery module outputting at least a output voltage based on the selected at least a battery connection configuration.
