# Ford Electric Vehicle Battery Longevity Study

A new study by Ford has shed some light on the long-term reliability of its electric vehicle batteries, showing a significant retention of battery health after five years.

Ford has released data on the long-term health of its electric vehicle batteries, providing insight into how they hold up after thousands of miles and hundreds of recharges. The study analyzed over 36,000 Mustang Mach-E electric SUVs sold in the US and Canada during the initial 2021 model year.

The results show that even after more than five years on the road, with an estimated 2 billion cumulative miles driven, the average battery health is still at a respectable 92%. This data should be reassuring for potential buyers of electric vehicles who have concerns about their long-term reliability. Battery durability has been one of the biggest concerns for early adopters and those considering making the switch to electric.

The high battery health after such a significant amount of use is notable, especially given that the batteries are subject to degradation over time. However, it's worth noting that the data is largely in line with what other automakers and independent analysts have reported across the industry.

Despite some concerns about long-term reliability, many electric vehicle owners remain confident in their cars' ability to last as long as a traditional combustion engine. The battery is the most expensive component of an electric car, making it a crucial factor for owners to consider when purchasing a new vehicle.

As more used electric vehicles (EVs) enter the market, concerns about battery longevity have been a major hurdle for potential buyers. Many experts have touted pre-owned and off-lease EV deals as a way to bypass the high cost of new electric cars, but shoppers may be hesitant due to worries about reduced range or costly battery replacements.

A new study by Ford has shed some light on this issue, providing valuable data that could alleviate these concerns. The automaker examined over 36,000 vehicles delivered to customers across the US and Canada during their first year of sales, with results showing a significant retention of battery health after five years.

According to Ford's findings, around 95% of vehicles surveyed retained between 87% and 97% of their original battery health, averaging an impressive 92%. This means that despite extensive use - an estimated 2 billion cumulative miles driven over the past five years - the batteries in these EVs have held up remarkably well.

The implications of this study are significant, as it suggests that EV owners can expect to retain a substantial portion of their vehicle's advertised range even after extended periods of use. For example, the 2021 Mustang Mach-E, which had an EPA-estimated range of between 211 and 305 miles, saw owners lose around 16 to 24 miles of range over time.

Despite the seemingly inevitable degradation of electric vehicle (EV) batteries over time, new data from Ford suggests that its EV battery health remains surprisingly robust even after extensive mileage. In a group of 2,000 vehicles that exceeded the 100,000-mile mark, around 91% of their original battery capacity was retained.

A smaller subset of about 30 drivers who reached an impressive 200,000 miles in their Mach-Es showed an average battery health of 88%. This trend indicates that more miles driven does indeed result in some wear and tear on the batteries. However, the extent to which this affects overall performance is still a topic of interest for EV owners.

An independent study by Aviloo provides further evidence supporting Ford's findings. The Austrian firm analyzed data from over 500,000 EVs across 20 global brands, measuring battery degradation at various mileage thresholds including 50,000, 100,000 and 150,000 kilometers. The results showed that many popular models maintained an impressive 90% or more of their original battery health even at high mileage.

Notably, Tesla's Model Y was found to retain around 90.3% of its battery capacity at 150,000 kilometers, while the Volkswagen ID4 and Hyundai Ioniq 5 demonstrated similar levels of retention with 90.6% and 92.8%, respectively. In contrast, the first-generation Nissan Leaf showed more pronounced degradation at 86.3%.

The study found that Ford's electric vehicle (EV) batteries show remarkably little degradation after 5 years of use. This is in line with the manufacturer's design goal for the Mach-E's battery to last at least a decade.

Ford is transitioning to a newer lithium iron phosphate chemistry for its upcoming Fathom small electric pickup, which will require different charging needs and calibration than previous models. The company's Universal Electric Vehicle platform also supports bidirectional charging, allowing EVs to power homes in addition to being charged themselves.
