Abstract: The disclosure relates to a cooling system for one or more battery cells of an electric battery, comprising: a cooling conduit for coolant fluid, wherein the cooling conduit is arranged for cooling of at least one battery cell of the electric battery, characterized in that, the cooling conduit has a variable dimension being indicative of a variable amount of coolant fluid to flow in the cooling conduit, and the variable dimension of the cooling conduit is variable in dependence on a cell swelling mechanism of the at least one battery cell.

Abstract: A method and a device for operating an internal combustion engine make it possible to set a setpoint value for the overall fresh air mass flow as the top control target. The internal combustion engine has a multi-flow air system including a multi-channel air supply and a corresponding multi-channel exhaust gas discharge, exhaust gas being recirculated from the multi-channel exhaust gas discharge into the multi-channel air supply and the exhaust gas recirculation being regulated for setting a setpoint fresh air mass flow. A value for the required overall fresh air mass flow of the internal combustion engine is predefined for at least one exhaust gas recirculation channel as the setpoint for the exhaust gas regulation.
