沃尔沃 CTO 详解 EX60 电子门把手：双冗余 + 机械应急

Core Viewpoint - Volvo's new electric SUV EX60 features a shark fin-shaped electronic door handle, which has sparked significant attention due to its innovative safety configurations amidst ongoing debates about the safety of electronic door handles [1] Group 1: Safety Innovations - Volvo's CTO, Anders Bell, emphasized that the focus should be on system safety rather than the door handle itself, highlighting the importance of redundancy in design for reliable and quick vehicle exit during collisions [1] - The EX60's external shark fin door handle includes an internal button that allows the door to open mechanically even if the vehicle's battery is compromised, addressing a critical safety concern regarding electronic door handles [2] Group 2: Dual Opening Mechanism - The EX60 features a dual opening mechanism where a light pull activates the electronic opening and a stronger pull activates the mechanical opening, providing a backup for occupants in various scenarios [2] - In the event of a collision, the vehicle will automatically unlock the doors, allowing external rescuers to open the doors even if the 12V battery is completely dead or damaged [2] Group 3: Power Supply Redundancy - The EX60 is equipped with two DC-DC converters located in a highly protected area beneath the rear seats, ensuring that as long as one converter is operational, the emergency systems will receive stable 12V power [3] - This design significantly reduces the likelihood of total power system failure, thereby providing a solid power guarantee for emergency door opening [4]
