A battery system is provided. The battery system includes a cooling plate having a housing, an inlet port, and an outlet port. The housing defines an interior region. Both the inlet port and the outlet port fluidly communicate with the interior region. The battery system further includes a solid thermoplastic cooling fin having first and second panel portions. The first panel portion is disposed directly on and against the cooling plate. The battery system further includes a first battery cell disposed directly on and against a first side of the second panel portion of the solid thermoplastic cooling fin. The solid thermoplastic cooling fin is configured to conduct heat energy from the first battery cell to the cooling plate.

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; anda 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; anda 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. 2. The battery system of claim 1, wherein the first panel portion is a substantially flat rectangular-shaped panel portion, and the second panel portion is a substantially flat rectangular-shaped panel portion. 3. The battery system of claim 1, further comprising first and second plastic frame members disposed against the first and second lithium-ion pouch-type battery cells, respectively, such that the first and second lithium-ion pouch-type battery cells and the second panel portion of the solid thermoplastic cooling fin are disposed between the first and second plastic frame members. 4. The battery system of claim 3, further comprising first, second, third, and fourth bolts adapted to couple the first and second plastic frame members to one another. 5. The battery system of claim 1, wherein the first side of the second panel portion of the solid thermoplastic cooling fin being sized and shaped to cover substantially all of a first side of the outer surface of the substantially rectangular-shaped pouch-type body. 6. The battery system of claim 1, further comprising a refrigerant supply system adapted to supply a refrigerant to the inlet port of the cooling plate such that the cooling plate transfers heat energy from the solid thermoplastic cooling fin to the refrigerant flowing through the cooling plate. 7. The battery system of claim 1, wherein the solid thermoplastic cooling fin is disposed away from and does not communicate with an internal region of the rectangular-shaped pouch-type body of the first lithium-ion pouch-type battery cell. 8. The battery system of claim 1, wherein the solid thermoplastic cooling fin has a thermal conductivity of 5 Watts/meter-Kelvin. 9. A method of assembling a battery system, comprising: providing 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;providing 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;providing a first lithium-ion pouch-type battery cell having a rectangular-shaped pouch-type body with an outer surface;providing a second lithium-ion pouch-type battery cell having a rectangular-shaped pouch-type body with an outer surface;disposing the first panel portion of the solid thermoplastic cooling fin directly on and against the cooling plate;disposing the outer surface of the rectangular-shaped pouch-type body of the first lithium-ion pouch-type battery cell directly on and against the first side of the second panel portion of the solid thermoplastic cooling fin, such that 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; anddisposing the outer surface of the rectangular-shaped pouch-type body of the second lithium-ion pouch-type battery cell directly on and against the second side of the second panel portion of the solid thermoplastic cooling fin such that a bottom end of the rectangular-shaped pouch-type body of the second lithium-ion pouch-type battery cell being disposed the second distance away from the first panel portion of the solid thermoplastic cooling fin and being further disposed the third distance away from the cooling plate. 10. The method of claim 9, further comprising disposing first and second plastic frame members against the first and second lithium-ion pouch-type battery cells such that the first and second lithium-ion pouch-type battery cells and the second panel portion of the solid thermoplastic cooling fin are disposed between the first and second plastic frame members. 11. The method of claim 10, further comprising coupling the first and second plastic frame members to one another utilizing first, second, third, and fourth bolts. 12. The method of claim 9, wherein the solid thermoplastic cooling fin is disposed away from and does not communicate with an internal region of the rectangular-shaped pouch-type body of the first lithium-ion pouch-type battery cell. 13. The battery system of claim 9, wherein the solid thermoplastic cooling fin has a thermal conductivity of 5 Watts/meter-Kelvin.
