    • A protective device for galvanic cells (201, 202, 301, 302) which are interconnected via contact elements (205, 207, 209, 212, 405, 409, 406, 407, 506, 507, 509, 606, 607, 706, 707, 709, 805, 806, 807, 809) that are suitably connected to pole connections (203, 204, 503, 504) of said cells to give a battery can be associated with individual cells of a battery. The protective device has an activation device (1008, 1108, 1208, 1011, 1111) for activation. When the protective device is activated, the protective device bridges the cell associated therewith by changing the interconnection and thus removes it from the electrical functioning of the battery assembly. In the activation device, preferably an electroconductive or insulating component made of a shape memory material brings about the change of the interconnection by changing the shape of said component as soon as and/or as long as the temperature of said component lies outside a defined temperature range.
    • 用于原电池(201,202,301,302)的保护装置中,接触元件通过与这些细胞的电极端子(203,204,503,504),其连接在一个适当的方式(205,207,209,212,405,409,406, 407,506,507,509,606,607,706,707,709,805,806,807,809)被连接到电池,电池的各个单元可以被分配。 该保护装置具有激活装置(1008,1108,1208,1011,1111),用于它们的激活。 当激活安全装置,该安全装置通过改变互连绕过它的相关联的小区,并把他们从电池所以复合电出来的。 在活化装置最好尽快使由形状记忆材料的导电或绝缘元件,所述互连通过在该装置中的形状变化的变化,如和/或只要该装置的温度处于规定的温度范围之外。
