1. A battery system, comprising:

  • a cooling plate having a housing, an inlet port, and an outlet port, the housing defining an interior region, both the inlet port and the outlet port fluidly communicating with the interior region;

    a solid thermoplastic cooling fin having first and second panel portions, the second panel portion having first and second sides, the first panel portion being coupled to an end of the second panel portion, the first panel portion extending substantially perpendicular to the first and second sides of the second panel portion and past the first side of the second panel portion a first distance, the first panel portion being disposed directly on and against the cooling plate; and

    a first lithium-ion pouch-type battery cell having a rectangular-shaped pouch-type body with an outer surface being disposed directly on and against the first side of the second panel portion of the solid thermoplastic cooling fin, and a bottom end of the rectangular-shaped pouch-type body of the first lithium-ion pouch-type battery cell being disposed a second distance away from the first panel portion of the solid thermoplastic cooling fin and being further disposed a third distance away from the cooling plate, the solid thermoplastic cooling fin configured to conduct heat energy from the first lithium-ion pouch-type battery cell to the cooling plate; and

    a second lithium-ion pouch-type battery cell disposed directly on and against the second side of the second panel portion of the solid thermoplastic cooling fin, the solid thermoplastic cooling fin configured to conduct heat energy from the second lithium-ion pouch-type battery cell to the cooling plate.
