Abstract: A method for electrically charging an energy storage of a motor vehicle at an electrical energy source external to the vehicle from a specific initial charge state of the energy storage to a specific final charge state of the energy storage. A control device controls the charging according to the first charging mode such that the energy storage is charged by the external energy source with a first charging power and according to a first overall efficiency. In addition, the control device determines whether an activation request made by a user to activate a second charging mode, which represents an energy saving mode, has been received, and at least if this is the case, the control device controls the charging process according to a second charging mode.

Abstract: A battery arrangement with a battery module, which includes a cell stack with multiple battery cells arranged next to one another in a stacking direction and one or more cell separation elements. One of the cell separation elements is arranged between respective two battery cells arranged adjacent to one another. At least one of the cell separation elements protrudes on one side of the cell stack from a gap between the two battery cells, in which the cell separation element is arranged. The protruding cell separation element is connected to an active cooling device through which a cooling medium can flow and which is encompassed by the battery arrangement.

Abstract: A protective arrangement for a motor vehicle for protecting a high-voltage battery of the motor vehicle from the penetration of liquid. The protective arrangement has an electrical component connected to the high-voltage battery via a cable, which component has a drainage device with a drain opening and a closure, by which the drain opening can be released depending on the pressure, a cooling circuit with a circuit component arranged on the component housing, through which component a coolant can flow, and with a pump to pump coolant through the circuit component, and a control device, which is designed to control the pump depending on detection of at least a probable penetration of coolant into the component housing in such a way that an increased pump power is at least temporarily provided by the same if the pump is not yet in a state of maximum pump performance.
