A cap assembly (10, 20) for a battery cell (30) having electronic safety functionality comprises a cap plate (100) being electro-conductive,a first terminal (110a) to be coupled to a first electrode (60) of the battery cell (30), and a second terminal (110b) to be coupled to a second electrode (80) of the battery cell (30). The cap assembly (10, 20) further comprises an electrical device (120) having a variable electrical conductivity. The first terminal (110a) is coupled to the cap plate (100) by the electrical device (120),and the second terminal (110b) is electro-conductively connected to the cap plate (100). The electrical device (120) is configured such that an electrical conductivity of the electrical device (120) is dependent on a voltage between the first terminal (110a) and the second terminal (110b).
