EV Batteries vs ICE Engines
View(s):As Sri Lanka’s largest electric vehicle portfolio provider, Evolution Auto has initiated a fact-based national conversation around one of the most critical aspects of electric vehicle ownership: battery health and longevity.
Consumers who are switching from petrol and diesel vehicles remain hesitant, despite the growing interest in electric mobility. How long the battery will last is always the most common question. According to Evolution Auto, the conversation must shift from assumption to evidence-based comparison, it said in a media release.
In comparison to internal combustion engine (ICE) vehicles, modern electric vehicles (EVs) are steadily demonstrating greater mechanical simplicity, durability, and predictability. Today it is more relevant to compare EV batteries with the cumulative mechanical wear associated with ICE engines rather than with uncertainty.
Global research conducted by Geotab, based on data from more than 22,700 electric vehicles across multiple brands and geographies, provides measurable clarity. According to the study, the average yearly degradation rate of EV batteries is just 2-3 per cent. After eight years of use, the majority of batteries maintain more than 80 per cent of their original capacity at this rate.
The research shows that battery deterioration occurs gradually rather than abruptly. Many modern EV batteries are predicted to remain over 70 per cent capacity for 15 to 20 years based on observed deterioration trend lines; this benchmark is frequently regarded as the functional threshold for usable automotive performance. Practically speaking, this implies that the battery may frequently outlive the vehicle’s typical ownership lifecycle, the statement said.
The study further highlights that while moderate climates and effective thermal management systems greatly preserve battery health, prolonged exposure to intense heat might accelerate degradation. More recent EV generations have better long-term durability than earlier models thanks to improvements in battery chemistry and management software.
These findings support the idea that modern EV battery systems are engineered for consistent performance, predictable aging, and long-term use, shifting the focus of the longevity discussion from concern to measurable engineering evidence.
By contrast, ICE vehicles inevitably experience wear across multiple interconnected systems, including engines, gearboxes, exhaust assemblies, fuel injection systems, clutches, and cooling mechanisms. As these systems age, maintenance complexity and costs typically increase. In contrast to battery degradation, which is often progressive and quantifiable, mechanical wear in ICE vehicles can occur randomly across multiple components at once.
