1. A system, comprising:
a power optimized energy source;
an energy storage optimized source;
a DC to DC charger; and
a network that combines a first current from the power optimized energy source and a second current from the energy storage optimized source in order to power a load at least during a high power demand event, including by connecting the power optimized energy source and the energy storage optimized source using a parallel connection, wherein:
there is a plurality of power optimized energy sources and a plurality of energy storage optimized sources;
the network includes at least a first string and a second string in parallel;
the first string includes a first plurality of single-source sub-packs in series;
at least one single-source sub-pack in the first plurality of single-source sub-packs includes the plurality of energy storage optimized sources in parallel;
the second string includes a second plurality of single-source sub-packs in series;
at least one single-source sub-pack in the second plurality of single-source sub-packs includes the plurality of power optimized energy sources in parallel; and
the first string is an energy string having a first voltage and the second string is a power string having a second voltage.
