The lunchbox has a lid and a housing that can be interconnected. The lunchbox has an electrical heating element, a device for power supply and for controlling the power supply and operating modes, and a sensor arrangement for controlling the temperature of the heating element.

Abstract: A method and device for training an energy management system in an on-board energy supply system simulation, includes: simulating a driving cycle having defined recuperation; plotting state variables of the on-board energy supply system; calculating a recuperation power from a recu-peration current and a battery voltage; producing input vectors for a neural network; producing a reward function; and training the neural network.

Abstract: The invention relates to a lunchbox for storing, transporting and heating food, in particular food prepared for consumption. This should be easy to handle. The lunchbox comprises an upper shell (1) and a lower shell (2) which connected to one another in a hinged manner on one longitudinal side, wherein a closure is provided on the opposite longitudinal side. A shell having a circumferential and L-shaped angled edge region is arranged in the lower shell (2), which is assigned a thermal insulation and a heating element, wherein a groove for receiving a seal is formed in the circumferential edge region of the shell.
