Abstract: A battery system, in particular a lithium-ion system, includes at least one battery device, at least one first housing element, at least one second housing element, and a closing device. The housing elements have a common connecting hinge that enables moving at least one of the housing elements about a common rotation axis, and are configured to move into a closed position whereat the housing elements define a common closed interior. The housing elements are also configured to receive the battery device. The closing device is configured to automatically move at least one of the housing elements about the common rotation axis into the closed position.

Abstract: 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.
