Electric Truck Batteries: Longer Lifespan Than Expected

Electric Truck Batteries: Longer Lifespan Than Expected

Posted on January 8, 2025

A new study from Geotab offers some reassuring news for electric vehicle (EV) owners and fleet operators concerned about battery longevity. The study reveals that, on average, EV batteries retain 91% of their original capacity after five years. This finding provides a more optimistic outlook than earlier studies, which often suggested quicker and more severe degradation. Geotab’s analysis, based on real-world fleet data, shows that advancements in battery technology are contributing to improved longevity, with batteries now degrading at an average rate of just 1.8% annually.

Battery degradation has been one of the primary concerns holding back widespread EV adoption, with many skeptical about whether these vehicles can truly last as long as their traditional counterparts. However, this latest study challenges those misconceptions. The real-world data shows that while degradation still occurs, it happens at a much slower and more manageable rate than previously anticipated. This is significant for fleet managers who rely on EVs for long-term operations and want to maximize their return on investment.

The data also highlights the importance of other factors in battery performance. Usage patterns, climate conditions, and charging behavior can all impact the lifespan of an EV battery. Additionally, the introduction of ultra-fast chargers may have an unknown effect on battery health, further complicating the picture. As such, fleet operators are advised to pay close attention to these variables and use reliable data to make informed decisions about vehicle performance and battery management.

The improved battery resilience shown in Geotab’s study should provide fleet managers with the confidence to embrace EVs as a more viable and sustainable alternative to traditional gas-powered vehicles. With lower degradation rates, EVs can remain on the road longer, reducing the need for costly battery replacements and offering better value over time. This makes electric fleets an even more appealing option for businesses looking to reduce operating costs and meet sustainability targets. As technology continues to evolve, future innovations in battery life, charging infrastructure, and vehicle design will further strengthen the case for electric vehicles.
