Modular battery network systems and methods for managing modular battery network systems

A battery network, comprising:

• a plurality of battery blades, each comprising:
• a plurality of cell groups, wherein each cell group of the plurality of cell groups includes a plurality of battery cells and a connection mechanism configured to establish an adjustable connection between the plurality of battery cells in a cell group;
• and
• a processor in communication with the plurality of cell groups, the processor configured to control each connection mechanism at least partially based on a state of charge of at least one of the plurality of battery cells in each of the plurality of cell groups,
• wherein the processor is further configured to optimize output power of each of the plurality of cell groups based on state of charge (SOC) C and load L of each of the plurality of cell group i by determining whether cell group i have sufficient SOC based on Ci−Li≥Cthreshold and calculating a supplemental power ΔLi=Li−Ci+Cthreshold when cell group i have insufficient SOC, wherein the processor is further configured to determine an optimal solution for an optimization function defined as:
