How does the Xiaomi Pengcheng series achieve a long maintenance cycle of 3 years or 30,000 km for the range extender?

Official answer

The range extender equipped in the Xiaomi Pengcheng series is deeply customized by Xiaomi EV and Dong'an Power. The design of 57 components has been optimized, with a focus on developing 7 core components that account for nearly 50% of the total machine cost, to reduce operational wear at the hardware level and lay the foundation for achieving a long maintenance cycle.

In addition, we have partnered with Shell, a leading global engine oil supplier, to customize engine oil meeting the industry's highest standard grade, API SQ 0W-16, for the Xiaomi Pengcheng series range extender. It has the following multiple advantages:

  • It uses high-purity, low-volatility fully synthetic base oil, balancing high performance with ultra-low oil consumption to support long-term stable lubrication.
  • At the same time, it has excellent viscosity-temperature characteristics, adapting to the frequent start-stop range extension operating conditions to achieve high efficiency and energy saving.
  • The dedicated antioxidant additive system in the customized engine oil, combined with a reinforced cleaning and dispersing system, can comprehensively extend the maintenance cycle.
  • The Xiaomi Pengcheng series is also equipped with an intelligent dynamic health monitoring mechanism. That is, it dynamically monitors engine oil health based on the user's driving habits and environment. Users can intuitively view the engine oil health through the infotainment system or the Xiaomi EV App, and it will proactively push reminders at maintenance nodes for on-demand maintenance.
