Abstract
A method for optimized energy management of an electrical system is provided for protecting a component to be protected of the electrical system. The power dissipation of at least one component to be protected is determined, the expected temperature increase is calculated using a thermal model, the expected temperature increase is compared with a predefined temperature threshold value. Consumer loads are switched on or off depending on their priority. A device for carrying out the method is provided. The device includes a power meter, calculation unit storage unit, and switching unit for switching consumer loads The electrical system to which the device is assigned includes at least one consumer load and at least one component to be protected.

A method for optimized energy management of an electrical system, comprising:
- determining power dissipation PDiss of at least one component to be protected of the electrical system;
- inputting the power dissipation PDiss into a thermal model of the at least one component to be protected;
- calculating a temperature increase ΔT to be expected of the at least one component to be protected;
- comparing the temperature increase ΔT to be expected with a predefined temperature threshold value TMax;
- disconnecting a consumer load from a mains depending on the consumer load's priority when a predefined temperature threshold value TMax is exceeded;
- and
- connecting a consumer load to the mains depending on the consumer load's priority when the temperature falls below the predefined temperature threshold value TMax.
A device for optimized energy management of an electrical system, comprising:
- at least one power meter that measures an input power PIn an output power POut,
- a calculation unit that calculates a power dissipation PDiss and a temperature increase ΔT to be expected or an end temperature TEst to be expected, and that compares the end temperature TEst to be expected with a temperature threshold value TMax,
- a storage unit storing priorities of consumer loads and efficiencies of one or more components to be protected,
- a switching unit that switches the consumer loads,
- wherein the electrical system comprises the following components at least one energy source,
- at least one consumer load,
- at least one component to be protected.
