Cooling system integrated with vehicle battery tray

A battery support tray for a vehicle, said battery support tray comprising:

• a peripheral sidewall comprising a pair of tray frame members that border opposing sides of a battery containment area;
• and
• a tray floor structure comprising a plurality of elongated floor sections disposed parallel and adjacent to each other and each having a length spanning between the pair of tray frame members below the battery containment area,
• wherein the plurality of elongated floor sections each comprise a cross-sectional profile that is consistent along the length of the respective elongated floor section,
• wherein the cross-sectional profile of each of the plurality of elongated floor sections comprises (i) a panel portion having an upper surface that thermally couples with battery modules in the battery containment area and (ii) a conduit portion integrally formed with the panel portion and disposed below the panel portion, and
• wherein the conduit portion of the cross-sectional profile encloses a coolant channel that integrally extends along the length of the respective elongated floor section.
