    adaptation with which construction space is saved, as well as better control of the discharge of the energy storage unit.
    The adaptation unit can be managed by means of an external and / or interconnected control and / or regulation unit, thus adapting the adjustments made. However, in the preferred embodiment of the invention, it is proposed that the adaptation unit be autonomous. Thus, advantageously simple, economical and safe control can be achieved. The expression that the at least one adaptation unit is “autonomous” includes the concept that, in at least one operating state, specifically, a discharge operating state, the adaptation unit modifies its state in a manner automatic and mechanical depending on an instantaneous discharge parameter, in particular a discharge current and / or a discharge voltage, of the at least one main connection unit. The adaptation unit has no direct connection to an external control unit.
    In order to adapt the discharge parameter in a particularly efficient manner and to better discharge the energy storage unit, it is proposed that the adaptation unit comprises at least one adaptation connection unit. The adaptation connection unit comprises at least one adaptation connection element configured as MOSFET, so that the influence exerted on the discharge parameter can be better and controllable.
    Likewise, it is proposed that, in order to achieve a particularly efficient adaptation of the discharge parameter, a control terminal of the adaptation connection unit is connected to a power terminal of the main connection unit indirectly through at least one resistor. The influence exerted on the discharge parameter, in particular, the discharge current, can be directed by means of the adaptation connection unit of the adaptation unit, by means of a measured control signal of the discharge parameter, at the Adaptation connection unit control. Thus, a better and faster influence on the download parameter can be achieved.
    In addition, it is proposed that the main connection unit be made as an inverter switch, where the main connection unit has a maximum connection time of 10 ms. Preferably, the inverter is intended to supply and / or generate an oscillating electric current, preferably with a frequency of at least 1 kHz, more preferably, at least 10 kHz and, advantageously, at least 20 kHz, to operate the at least one induction heating element.
