Modern PPE-platform EVs rely on a pyrotechnic fuse to isolate the traction battery during a collision. The new 0Z3915631B High-Voltage Pyrofuse fits compatible Audi A6, Q6 and SQ6 e-tron models, plus selected electric Porsche Macan and facelift Taycan vehicles. Installed inside the battery control module, it includes a 1-year warranty and requires professional high-voltage handling.
