a plurality of battery cooling plates, each having a coolant inlet, a coolant outlet, and a coolant flow path extending through the battery cooling plate between the coolant inlet and the coolant outlet;

a coolant chiller configured to remove heat from a flow of coolant;

a coolant manifold including:

a first coolant chamber extending in a longitudinal direction and fluidly coupled to the coolant chiller to receive a flow of coolant therefrom;

a second coolant chamber extending in the longitudinal direction and fluidly coupled to the coolant chiller to deliver a flow of coolant thereto, the second coolant chamber and the first coolant chamber being spaced apart and separated by an air gap, the air gap formed between the first and second coolant chambers;

a series of webs arranged along the longitudinal direction to join the first and second coolant chambers, wherein the first coolant chamber, the second coolant chamber, and the series of webs are provided as a monolithic aluminum structure, and wherein the air gap is formed in between two of the series of webs, the series of webs structurally holding the first coolant chamber to the second coolant chamber; and

a plurality of plastic connectors in one-to-one correspondence with the plurality of battery cooling plates, each mounted to the coolant manifold and each including a first fluid port connected to the first coolant chamber, a second fluid port connected to the second coolant chamber, a third fluid port in fluid communication with the first fluid port through the plastic connector, and a fourth fluid port in fluid communication with the second fluid port through the plastic connector, the third fluid port being fluidly coupled to the coolant inlet of the corresponding battery cooling plate and the fourth fluid port being fluidly coupled to the coolant outlet of the corresponding battery cooling plate,

wherein at least one of the plurality of plastic connectors is mounted to the coolant manifold and extends from the first coolant chamber to the second coolant chamber and across the air gap, and

wherein the third and fourth fluid ports of the plurality of plastic connectors are fluidly coupled to the plurality of battery cooling plates by way of hoses.
