![]() This means the battery has a long-term ‘useable’ capacity separate to its overall capacity that ensures the vehicle has a consistent driving range during its lifecycle. Some of the latest EVs have a battery pack that employs what are known as ‘buffers’, which are essentially sacrificial cells that are dedicated to degrade over time. This alone means that electric vehicles need to be recharged less frequently and can spread the storage (and flow) of electricity across all its cells, which reduces stress and prolongs the advent of degradation. It also needs to be recharged more often (every day in most cases), which increases the number of charge cycles.Īn EV battery is much larger and is subsequently made up of numerous cells, hence the term ‘battery pack’. But the physical size of a mobile phone generally means the battery is just a single cell that throttles the flow of electricity (and therefore performance) to prevent overheating. Yes, they are very similar in their chemical structures, as most modern rechargeable battery packs use a lithium-ion compound. In any case, it’s a little unfair to compare the battery in your phone to that in an electric vehicle. There are things you can do to preserve the life of an EV battery.The cost of battery replacement is expected to drop in the next few years.EV battery technology is getting smarter all the time.Some manufacturers offer an eight-year battery warranty. ![]() ![]() There's a multitude of reasons why EV batteries eventually fail.Battery degradation is frustrating but real.No matter whether it’s your phone, laptop or electric car, replacing your battery is an alternative solution to disposal, but just how viable is that as an option to extend the life an EV? Let’s find out… However, it’s the issue of high-voltage batteries that still has people most concerned, with 72 per cent of respondents concerned about the cost of replacement. The fourth in a series of carsales research pieces that surveys current and prospective EV owners reveals that while the cost of buying a new EV is still a significant barrier, that level of concern has decreased since the last round of research six months ago. ![]()
