At Nevo, our experts are always ready to answer questions and clear up rumours by focusing on the facts. Myths about electric vehicle batteries often come from outdated information or a lack of familiarity with the technology. Misconceptions about battery lifespan, environmental impact, and charging times still pop up, partly because early EVs did have their limitations. This kind of misinformation can spread quickly through the media and word of mouth, creating confusion. But as technology advances and public awareness grows, these myths are being debunked. In this instalment, we’re tackling five more questions that frequently come up.

Is it true that old EV batteries will be an environmental hazard?

Old EV batteries can certainly pose an environmental risk if not managed correctly. They contain materials like lithium, cobalt, and nickel, which can contaminate soil and water if improperly disposed of. However, advancements in recycling technology and second-life applications, such as using these batteries for energy storage systems, are helping to reduce these risks. Proper recycling programs and regulations play a key role in minimising their environmental impact. Even car breakers and dismantlers now have specialised training and equipment to safely remove and handle these batteries. Once removed, the batteries can be repurposed, recycled, or safely disposed of, ensuring that valuable materials are recovered and the risk of environmental contamination is kept to a minimum.

Does charging an EV still take too long?

If we’re talking about some of the less modern EVs, the honest answer is probably yes—charging an EV does still take longer than refuelling a traditional car, but advancements are significantly reducing that time. In a lot of cases, fast chargers can top up an EV battery to 80% in less than 30 minutes, which is ideal for quick stops. On the other hand, standard home charging with a Level 2 charger usually takes several hours, typically overnight, to fully charge a battery. Improvements in public charging infrastructure and the development of ultra-fast chargers are helping to address these concerns. While charging times are still longer than refuelling, the convenience of home charging and the faster speeds of public chargers are making EVs more practical for daily use.

Is it true that EV batteries have a short lifespan?

Perhaps in the past, but here at Nevo, we believe it’s safe to say that EV batteries no longer have a short lifespan. Most modern EV batteries are designed to last up to 15 years, with many manufacturers offering extensive warranties. Advancements in battery technology are increasing both longevity and performance, with many batteries retaining around 80% of their capacity even after years of use. Proper maintenance and smart charging habits can further extend their lifespan. While some degradation over time is inevitable, EV batteries generally offer a service life that rivals, or even exceeds, many internal combustion engine components. It’s now common to see EVs with high mileage still maintaining battery health above 80%.

Will EV battery technology improve any further?

Yes, EV battery technology is expected to improve significantly, much like how mobile phone batteries have advanced rapidly over the past decade. Researchers are working on innovations such as solid-state batteries, which promise higher energy density, faster charging times, and improved safety compared to current lithium-ion batteries. Other advancements in battery chemistry, like silicon anodes and lithium-sulfur batteries, aim to boost capacity and extend lifespan. Additionally, improvements in manufacturing processes and recycling methods will help lower costs and reduce environmental impact. Smart battery management systems are also being developed to optimise performance and prolong battery life. These advancements will make EVs more efficient, affordable, and sustainable, addressing many of the current limitations and finally putting some old myths to rest.

As EV technology evolves, so does the understanding of its capabilities, with improved battery lifespans, faster charging times, and a growing focus on sustainability. At Nevo, we are here to guide you through the facts and help you make informed decisions as the world moves towards a more electric future.
