BEIJING, 5 April 2026 – China’s electric vehicle (EV) revolution has transformed the global auto industry, but as millions of cars age on the road, a new challenge is emerging, ownership costs and performance issues over time are becoming increasingly visible.
Once celebrated for low running costs and cutting-edge technology, EVs are now entering a phase where durability, maintenance, and long-term value are under scrutiny.
The Hidden Cost of Ageing EVs
For many early adopters, the reality of ageing EVs is beginning to surface.
Drivers report:
- Slower system performance
- Declining driving range
- Reduced charging efficiency
In some cases, range has dropped by around 10% after just a few years, while charging speeds have also deteriorated, particularly at standard charging stations.
These changes may seem gradual, but they introduce a new layer of cost and inconvenience that many buyers did not initially anticipate.
Repairs: Not Always Cheap
While EVs are often marketed as requiring less maintenance than traditional cars, repairs, especially outside warranty, can be costly.
Owners have reported repair bills running into several thousand yuan for issues such as wiring or system faults.
The challenge is compounded by warranty structures:
- Battery warranties typically last 8 years or 120,000–150,000 km
- Other components are often covered for only 3 to 5 years
Once coverage expires, owners bear the full cost—shifting the financial equation of EV ownership.
Battery Replacement: The Biggest Risk
The most significant cost concern remains battery replacement.
Industry estimates suggest replacing a full EV battery pack can cost between 50,000 yuan and over 100,000 yuan, depending on the model.
This creates a critical dilemma:
- The cost can approach, or even exceed, the resale value of older vehicles
- Many owners choose not to replace batteries at all
Instead, they adapt usage, limiting travel distances or relying on the vehicle for short commutes.
Software Dependence Adds New Uncertainty
Unlike traditional vehicles, EVs rely heavily on software systems.
While some brands provide ongoing updates that help maintain performance, others, especially those from struggling startups, pose risks.
In recent years, several Chinese EV makers have faced financial difficulties, leaving some owners uncertain about:
- Future software updates
- Availability of spare parts
- Long-term servicing support
This introduces a new type of ownership risk: technology obsolescence, even if the car remains mechanically functional.
Charging and Infrastructure Pressures
China has built the world’s largest EV charging network, but rapid adoption has created new strains.
Challenges include:
- Slower charging speeds in ageing vehicles
- Imbalances between EV growth and charging availability
- Regional disparities in infrastructure access
Despite millions of charging points nationwide, demand continues to outpace supply in some areas, affecting user experience.
A Maturing Market Faces Its First Real Test
China’s EV market has expanded at unprecedented speed, with EVs accounting for over half of new car sales in recent years.
But the next phase of the industry will depend not on sales, but on sustainability of ownership.
Key questions now include:
- How long EVs can maintain performance
- Whether repair ecosystems can scale
- How manufacturers support vehicles over time
Implications for the Global EV Industry
China’s experience offers an early glimpse into challenges that could soon affect other markets.
For automakers:
- After-sales service and durability will become critical differentiators
- Battery lifecycle management will define long-term value
For consumers:
- Total cost of ownership is becoming more complex
- Initial savings may be offset by future repair or replacement costs
Outlook for Investors
For investors, the shift signals a new phase in the EV story.
Opportunities:
- Growth in EV servicing, maintenance, and battery recycling industries
- Advancements in battery technology to reduce degradation
- Expansion of charging infrastructure
Risks:
- Declining resale values of older EVs
- Consumer hesitation as long-term costs become clearer
- Financial instability among smaller EV manufacturers
From Growth Story to Reality Check
China’s EV boom is no longer just about rapid adoption, it is entering a phase of real-world testing.
As vehicles age, the focus is shifting from innovation and scale to durability, cost, and long-term reliability.
The success of the EV revolution will depend not just on how many cars are sold, but how well they endure over time.
