Claim:
1. A battery subunit, comprising: a plurality of battery modules that are connected in at least one of a parallel configuration and a series configuration, wherein each of the plurality of battery modules includes a plurality of battery cells; a thermal management system that contacts each of the plurality of battery modules, and is configured to dissipate operational heat of the plurality of battery modules; and a carrier unit that includes at least one carrier plate positioned on a side of the thermal management system that is remote from the plurality of battery modules, the carrier plate defining (i) at least two grooves arranged respectively at opposite lateral edges of the carrier plate and (ii) at least one profiled beading that extends between the grooves, wherein a portion of the thermal management system laterally overlaps a portion of the grooves, wherein the profiled beading has a first height gradient that laterally directs at least one of fluids situated in the carrier plate, condensation from the thermal management system, and leakage from the thermal management system towards at least one of the grooves, and wherein the grooves have a second height gradient that longitudinally directs the at least one of the fluids, the condensation, and the leakage along the grooves.
