Core Viewpoint - The article discusses the safety risks associated with the electronic door handles of new energy vehicles, emphasizing the importance of maintaining mechanical redundancy to ensure doors can be opened in emergencies [5][7][12]. Group 1: Safety Risks of Electronic Door Handles - New energy vehicles are prone to battery explosions during high-speed collisions, which can hinder rescue efforts if doors cannot be opened [5]. - The reliance on electronic systems for opening doors in new energy vehicles poses risks, especially if the electronic system fails after a collision [9][11]. - The article highlights that while some models can sense a collision and unlock doors, they still require manual operation to open, which can be problematic if the electronic handle fails [7][9]. Group 2: Solutions and Costs - Solutions to enhance safety include adding mechanical backup systems and redundant power sources, which typically increase the cost of each vehicle by around 100 yuan [5][9][12]. - Some manufacturers, like Audi, are integrating features such as a plastic pull cord that can be activated in emergencies, which also adds to the vehicle's cost [14]. - The article notes that the cost of advanced electronic door handles can be significantly higher, with full hidden handles costing up to three times more than semi-hidden ones, potentially reaching around 1,000 yuan per vehicle [7][12]. Group 3: Industry Standards and Testing - New regulations require that all vehicle door handles must have a mechanical release function, ensuring that doors can be opened without tools in emergencies [12]. - The article emphasizes the importance of rigorous testing and validation for electronic components in vehicles, with companies like Volkswagen adhering to strict standards that increase their BOM costs by approximately 20% [15][18]. - The automotive industry is urged to adopt more robust safety measures and testing protocols to prevent design failures that could lead to severe consequences [19].

Core Viewpoint - The article discusses the safety risks associated with the electronic door handles of new energy vehicles, emphasizing the need for mechanical redundancy to ensure that doors can be opened in emergencies, particularly after accidents [5][19]. Group 1: Safety Risks of Electronic Door Handles - New energy vehicles are prone to battery fires after high-speed collisions due to the physical and chemical properties of lithium batteries [5]. - The reliance on electronic systems for opening doors in new energy vehicles poses risks, as failures can prevent doors from opening even if they are not physically deformed [7][11]. - The design of hidden and semi-hidden door handles, while aesthetically pleasing, complicates the emergency opening process [7][12]. Group 2: Cost Implications of Safety Features - Adding mechanical redundancy to door handles can increase the cost of each vehicle by approximately 100 yuan, which can accumulate to tens of millions or even billions when multiplied by production volumes [6][9]. - The most expensive fully hidden door handles can cost around 1,000 yuan per vehicle due to the additional electronic systems involved [8][12]. Group 3: Regulatory Changes and Industry Standards - New regulations require that every car door must have a mechanical release function, ensuring that doors can be opened without tools in emergencies [15][16]. - The automotive industry is being pushed to adopt standardized emergency opening methods for hidden door handles, which will reduce user learning costs and enhance safety [16]. Group 4: Testing and Validation Challenges - Traditional automotive companies have rigorous quality management systems that include failure mode and effects analysis (FMEA) to anticipate potential failures and design redundancies [17][18]. - The testing standards for electronic door handles are as stringent as those for traditional mechanical handles, requiring extensive validation to ensure reliability [18]. Group 5: Industry Evolution and Consumer Expectations - The trend towards electronic door handles in vehicles is influenced by consumer preferences for cleaner and simpler designs, mirroring the evolution seen in consumer electronics [17]. - The automotive industry faces challenges in balancing rapid design iterations with the need for thorough testing and validation, as mistakes can have severe consequences [19].
