Abstract: A battery system, in particular for a vehicle, includes a battery system housing, wherein the battery system housing has an air inlet region and an air outlet region for the air flowing through the battery system housing and at least one battery unit. The at least one battery unit is accommodated in the battery system housing so that air flowing through the battery system housing can flow around the at least one battery unit.

Abstract: A method for operating a first and a second electrical load or consumer in an alternating current network. The method can be operated in an optional first operating mode, in which the positive and negative half waves for each load are controlled with a first leading edge phase angle. In addition, a second operating mode is provided, in which a first part of the positive and negative half waves for the first load and a second part of the positive and negative half waves for the second load are controlled with respective second leading edge phase angles. Furthermore, a device for performing the method, having first and second leading edge phase-angle control for the first and second loads.
