With recurring compatibility challenges in parts, how can the aftermarket maintenance of new energy vehicles overcome these obstacles?

 　　The recurring challenge of parts compatibility: how can the new energy vehicle after-sales maintenance sector overcome this impasse? In the realm of new energy vehicle after-sales maintenance, the issue of parts compatibility has become a critical bottleneck constraining industry development. From the adaptation of battery management systems to different battery types, to the matching of charging interfaces with diverse charging stations, and the coordinated operation of motor controllers with drive motors, compatibility issues permeate every stage of new energy vehicle maintenance.

　　The root cause of these compatibility challenges lies in inconsistent technical standards and a lack of coordination within the supply chain. Automakers operate independently in designing components, communication protocols, and interface standards, resulting in a fragmented market with incompatible parts.Multiple international standards for charging interfaces exist, while variations in DC fast-charging connectors deter owners from cross-border travel.

　　Automakers must abandon the ‘technical silo’ mentality, proactively participate in industry standardisation, and drive the unification of component interfaces, communication protocols, and data formats. By establishing open technical platforms, manufacturers can share resources with parts suppliers and third-party repair providers, thereby reducing compatibility R&D costs.

　　The professionalisation and standardisation of third-party repair facilities are equally critical. Technicians must acquire comprehensive competencies in high-voltage electrical protection, electrochemistry, and BMS software debugging, necessitating systematic training programmes for traditional mechanics’ transition.

　　Policy guidance and strengthened regulation form the foundation for resolution. Governments should introduce supportive measures encouraging manufacturers to open technical interfaces and share repair data, offering tax incentives or subsidies to enterprises actively contributing to standardisation. Strengthened oversight of the aftermarket is essential to rigorously combat practices such as parts monopolisation and data lock-in, thereby safeguarding a fair competitive environment.

　　With recurring compatibility challenges in parts, how can the aftermarket maintenance of new energy vehicles overcome these obstacles? By establishing a multi-stakeholder collaborative mechanism involving manufacturers, parts suppliers, repair organisations, and government bodies, compatibility issues in new energy vehicle aftermarket maintenance will gradually be resolved. This will propel the industry towards standardisation, professionalisation, and sustainable development.

How far can an electric car go?

  How far can an electric car go?  The range of an electric car is affected by a number of factors, so it is impossible to give a single answer. The following is a detailed analysis of the range of electric vehicles: Battery capacity: Battery capacity is one of the key factors determining  the range of an electric vehicle . The larger the battery capacity, the more electricity is stored and the longer the range. The plug-in hybrid version of the BMW X5, the 45e, is equipped with a 24 kWh lithium-ion battery and has an official range of 85 kilometres.   Driving habits: Driving habits have a big impact on the range of an electric car. Aggressive driving can cause the battery to discharge quickly, resulting in a shorter range. Smooth driving helps to extend the range.   Driving conditions: Driving conditions are also an important factor affecting the range of an electric vehicle. Driving on potholes will not only increase tyre wear and chassis burden, but also shor...

Why don’t all new energy vehicles use the same type of powertrain?

 　　Why don’t all new energy vehicles use the same type of powertrain? The core reason why new energy vehicles do not uniformly adopt a single powertrain is that there are significant differences between different technology routes in terms of performance, applicable scenarios and infrastructure requirements, and companies need to choose the optimal solution based on technical characteristics and market demand. 　　Pure electric vehicles use batteries as the only power source, with a simple structure and outstanding zero-emission advantages, but range and charging time are still bottlenecks. However, performance degradation in low-temperature environments and insufficient coverage of charging facilities still limit their application in long-distance travelling or inconvenient charging areas. 　　Plug-in hybrid vehicles combine a fuel engine with an electric motor to achieve pure electric driving for short distances through external charging, while relying on the fuel engin...

Xiaomi YU7 Sells Out on First Day: Lei Jun’s ‘High Specs, Low Price’ Strategy Ignites the Pure Electric SUV Market!

　　Xiaomi YU7 Sells Out on First Day: Lei Jun’s ‘High Specs, Low Price’ Strategy Ignites the Pure Electric SUV Market! Since its pre-sale launch, the Xiaomi YU7, the first pure electric SUV from Xiaomi Automobile, has quickly become the focus of the market. On the first day of sales, Xiaomi Automobile stores across the country were bustling with crowds, and the online order system temporarily experienced congestion due to surging traffic, prompting the company to urgently expand its servers to handle the overwhelming demand. 　　As Xiaomi Automobile’s debut model in the SUV segment, the YU7 has been anchored to a ‘technology for all’ approach since the product definition stage. Lei Jun stated at the launch event: ‘Xiaomi’s goal in entering the automotive industry is to enable global users to enjoy top-tier technology at a lower cost.’ The vehicle is equipped with Xiaomi’s self-developed Surge OS intelligent cockpit system, supporting seamless connectivity between smartphones an...
