The average lifespan of an Internal Combustion Engine (ICE) vehicle is around 133,000 miles. However, experts estimate that the average electric vehicle battery can last up to 200,000 miles. The Department of Energy predicts that current electric vehicle batteries should last beyond the warranty period, and that the lifespan of these packages would range between 12 and 15 years if used in moderate climates. If your electric car is regularly used in more extreme conditions, you can expect a lifespan of 8 to 12 years.
Most electric vehicle batteries will last 10 to 20 years before needing to be replaced. This is due to the “discharge” cycles that occur when driving and the “charge” cycles when the car is plugged in. Repeating this process over time affects the amount of charge the battery can hold, reducing its range and time needed between each trip to charge. Most manufacturers have a five- to eight-year warranty for the battery.
Electric vehicles must also use “isolated high-voltage lines” and be able to deactivate their electrical systems in the event of an accident or short circuit. Together with other techniques, such as intelligent cooling systems, this means that
electric carbatteries should offer a trouble-free lifespan for many years. A typical 40 kWh battery pack of a conventional electric car could be enough to power it for 150 miles or more, while Tesla's larger 100 kWh battery is valid for 375 miles according to the WLTP standard. Electric vehicle manufacturers are investing heavily to give car batteries a new lifespan in large-scale battery storage systems.
One of the innovations that led to the rise of electric vehicles in the last decade are lithium-ion batteries. An ion is an atom or molecule with an electrical charge caused by the loss or gain of one or more electrons. Electric motors also work as generators, so when you lift your foot off the accelerator, the car starts to slow down by converting its forward motion back into electricity; this happens more forcefully if you press the brakes. To preserve the battery life of an electric vehicle, manufacturers ensure that there is additional reserve capacity to compensate for degradation over time.In conclusion, electric car batteries are quite resilient and can last at least 10 years before needing to be replaced.
When a designated charging point isn't available, you can charge an electric car from a 13-amp household outlet, but this can be very slow.
