Electric switching device for an energy accumulator in an electric vehicle

A method for switching an electrical switching device for an energy accumulator of an electric vehicle,

• wherein the electrical switching device includes a housing including (i) at least one switching section arranged therein and comprising a first input contact, a second input contact and at least one output contact, and (ii) a rotational component mounted relative to the housing, such that the rotational component is rotatable about a switching axis and between at least one of an OFF position (I), a series-connecting position (II), and an ON position (III),
• wherein the rotational component comprises at least one conductor having at least two conductor contacts, which in the series-connecting position (II) connects the first input contact to the at least one output contact in an electrically conducting manner and in the ON position (III) connects the first input contact to the at least one output contact in an electrically conducting manner and the second input contact to the at least one output contact of the at least one switching section in an electrically conducting manner, and
• wherein the method comprises:
• monitoring an activity situation of the electric vehicle to detect a normal condition, an emergency condition and a crash condition of the electric vehicle,
• moving the rotational component of the electrical switching device into the OFF position (I) when one of the emergency condition is detected and the crash condition is detected.
