A battery module having a cooling manifold is provided. The battery module includes a plurality of battery cell assemblies having a plurality of heat exchangers. The battery module further includes the cooling manifold operably coupled to the plurality of battery cell assemblies. The cooling manifold has a manifold portion and a cover plate. The manifold portion has a peripheral wall, a rear wall coupled to the peripheral wall, and a flow diverter. The peripheral wall has a top portion with an inlet aperture extending therethrough. The rear wall has a plurality of outlet apertures extending therethrough. The cover plate is coupled to the peripheral wall opposite to the rear wall. The flow diverter extends from the rear wall and is disposed below the inlet aperture. The flow diverter is configured to receive fluid from the inlet aperture and to divert the fluid so that a substantially equal flow rate of the fluid is obtained through each outlet aperture of the plurality of outlet apertures to a respective heat exchanger of the plurality of heat exchanger for cooling the plurality of battery cell assemblies.
