High load relay for lithium-ion-battery, has main contacts, and closing element consisting of shape memory material that causes deformation of closing element when temperature of area of closing element lies above limit temperature

摘要

The relay (110) has main contacts (A, B) arranged at spatial distance to each other, and a closing element (224) comprising an armature (116) and a contact element (220). The closing element consists of shape memory material that causes deformation of the closing element when temperature of an area of the closing lies below limit temperature. The shape memory alloy causes another deformation of the closing element when temperature of the area lies above the limit temperature such that the closing element does not contact one of the main contacts in a closed position.
