Battery for hybrid vehicles with a safety device for interrupting a high-voltage circuit

A rechargeable battery for hybrid vehicles comprising:

• a housing;
• a plurality of electrochemical cells within the housing that are electrically connected to one another and form a high-voltage circuit;
• a high-voltage socket arranged on the housing that comprises two electrical poles, wherein the high-voltage socket is configured to be connected to a high-voltage plug;
• a catch on the high-voltage socket that is configured to interact with a locking element on the high-voltage plug for locking the high-voltage plug to the high-voltage socket;
• a low-voltage circuit;
• at least one contactor integrated in the low-voltage circuit for interrupting and closing the high-voltage circuit;
• and
• a service plug connector for closing and disconnecting the low-voltage circuit;
• wherein the service plug connector interacts with the high-voltage plug such that the high-voltage plug cannot be withdrawn from the high-voltage socket until the service plug connector has been removed from the rechargeable battery;
• and
• wherein the service plug connector is configured to block the locking element on the high-voltage plug of the rechargeable battery.
