The battery is one of the most important and expensive components of an electric car. That’s why battery health is a major concern when buying a used EV. How much of the original capacity remains? Has the driving range decreased over time? And could an expensive battery replacement be necessary in the future? <\/p>

While these concerns are understandable, the actual risks are often lower than you might think. Modern EV batteries are designed to last much longer than the batteries in smartphones or laptops. Advanced battery management systems continuously monitor factors such as temperature, charge level, and cell voltage, helping to protect the battery from excessive stress and potentially damaging conditions. <\/p>

However, all batteries age over time. Every EV battery gradually loses some of its usable capacity, a natural process known as battery degradation. The key question isn’t whether a battery will degrade, but how quickly and how much capacity it will lose. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

EV batteries age in two main ways. The first is cycle aging, which happens as the battery is charged and discharged. Each charging cycle causes a small amount of wear on the battery cells. Frequent fast charging, deep discharging, and regularly charging to 100% can accelerate this process. <\/p>

The second type is calendar aging, which occurs even when an electric car isn’t being driven. Battery age, temperature, and charge level during long periods of inactivity all play a role. For example, leaving an EV parked in extreme heat with a fully charged battery for several weeks can accelerate degradation compared to a car that’s driven regularly and kept at a moderate charge level. <\/p>

Both types of aging gradually reduce the battery’s capacity, meaning the car can travel fewer miles on a full charge. Significant battery degradation can also lower the vehicle’s resale value, making battery health an important factor when buying or selling a used electric car. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Battery State of Health (SoH): What does it mean?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Battery health is commonly measured using the State of Health (SoH). Expressed as a percentage, it shows how much of the battery’s original capacity remains. <\/p>

For example, a battery with a SoH of 90% can still store approximately 90% of its original capacity. If an electric car had a real-world range of 400 kilometres when new, its estimated range would now be around 360 kilometres under similar conditions. However, actual range also depends on factors such as temperature, driving habits, speed, tyres, and the use of heating or air conditioning. <\/p>

As a general guideline, a SoH of 90\u2013100% indicates excellent battery health, while 80\u201389% is usually considered good for an older EV. Between 70% and 79%, the loss of capacity becomes more noticeable and should be reflected in the vehicle’s resale value. If the SoH drops below 70%, it’s worth taking a closer look at the battery’s condition and warranty coverage. <\/p>

However, these figures are only a rough guide. Battery health also depends on factors such as the vehicle’s age, mileage, model, and how the SoH was measured. For example, a SoH of 82% might be perfectly reasonable for a nine-year-old EV but could be a warning sign in a car that’s only two years old. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
