Exclusive new data has delivered a jolt to the electric vehicle market, revealing that some car batteries can lose a staggering 40% of their health in just three years—far more rapidly than many manufacturers claim.
The alarming research, which analysed thousands of vehicles, suggests that the performance of a typical EV battery declines significantly faster than previously thought, potentially slashing the range and value of used electric cars.
Concerning Findings for Popular Models
The study paints a worrying picture for several mainstream models. The data indicates that some of the most common electric vehicles on UK roads are experiencing much faster-than-expected degradation.
This rapid decline means a car sold with a claimed 200-mile range could realistically only achieve around 120 miles on a full charge after just a few years of ownership, creating 'range anxiety' for second-hand buyers.
Implications for the Booming Second-Hand EV Market
This revelation throws a spanner in the works for the rapidly growing used electric car sector. Potential buyers, already cautious about battery life, may now think twice before purchasing a pre-owned EV without a comprehensive battery health check.
The findings could significantly impact resale values and challenge the perception of electric vehicles as long-term, low-maintenance investments.
What This Means for Current and Future EV Owners
For current owners, the research highlights the importance of proper battery maintenance and understanding warranty terms. For those considering an electric vehicle, it underscores the need for transparency around battery health reports and long-term performance expectations.
The industry now faces increased pressure to improve battery technology longevity and provide more accurate, realistic data on performance over time.
