Battery Subunit having Multiple Battery Modules that are connected to One Another in a Parallel and/or Series Manner, Battery System and Method for Producing a Battery Subunit

摘要

A battery subunit includes multiple battery modules that are connected to one another in a parallel and/or series manner, and a thermal management system that contacts each of the multiple battery modules. Each of the multiple battery modules has respective multiple battery cells. The thermal management system is configured to dissipate heat that occurs during operation of the multiple battery modules. The battery subunit further includes a carrier unit that comprises at least one carrier plate positioned on a side of the thermal management system that is remote from the battery modules. The thermal management system is configured to at least partially receive, and on at least two opposite lying edges comprises, in each case, one or multiple grooves configured to collect and/or drain off at least one of fluids that are situated in the at least one carrier plate, and condensation water and/or leakage from the thermal management system.
