Can parts from different brands of new energy vehicles be interchangeable?

 　　Can parts from different brands of new energy vehicles be interchangeable? The interchangeability of parts from different brands of new energy vehicles is influenced by multiple factors, including design architecture, technical standards, and supply chain strategies, resulting in varying degrees of compatibility. This also involves compatibility issues related to software protocols and safety certifications.

　　The interchangeability of body structure components and basic parts is often limited by physical dimensions and installation interfaces. Standardised components such as tyres and windscreen wipers may not be directly interchangeable between brands due to differences in parameters such as wheel hub size and windscreen wiper arm length.

　　More complex core components like motors and electronic control systems are typically deeply integrated with the vehicle’s overall architecture in terms of voltage platforms, communication protocols, and cooling structures. Cross-brand replacement requires resolving a series of technical challenges such as electrical compatibility, software flashing, and safety certification, making such applications extremely rare in practice.

　　The ‘three-electric system’ of new energy vehicles involves special requirements such as high-voltage safety, electromagnetic compatibility, and thermal management. During development, each brand establishes proprietary standards based on its own technical approach. Communication protocols for battery management systems, physical specifications and electrical parameters of charging interfaces, and drive logic of motor controllers may all have compatibility barriers due to brand differences.

　　Some brands adopt customised component designs to establish technical barriers or maintain profit margins, limiting third-party supplier participation and restricting the supply of components in the aftermarket. Other brands may enhance component interoperability through modular design or open licensing to reduce maintenance costs and expand after-sales service networks.

　　Can parts from different brands of new energy vehicles be interchangeable? In practical applications, the assessment of part interchangeability must be based on specific scenarios. However, for critical components related to safety and performance, strict adherence to original manufacturer specifications is mandatory, as cross-brand replacements pose significant risks. Even within the same brand, parts interchangeability may be limited due to differences in model year and configuration.
