Lifespan

Summary from sources above:

The average lifespan of an electric vehicle (EV) battery varies depending on the source and the type of battery. According to the US Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE), EV batteries typically have a lifespan of around 8 to 10 years or around 150,000 miles. This is based on data from testing and real-world use. However, the actual lifespan of a battery can also depend on factors such as the charging and discharging patterns, temperature, and the quality of the battery itself.

The International Energy Agency (IEA) states that the lifespan of EV batteries can vary between 8 and 20 years, depending on the usage and battery technology. They also point out that manufacturers are working to improve the longevity and durability of batteries, and some newer models are expected to last longer.

The Argonne National Laboratory's Transportation Technology R&D Center states that the lifespan of EV batteries can be around 10-15 years, but it also depends on many factors such as the usage pattern, battery chemistry, and temperature, etc.

• Most EV batteries are guaranteed for 8 years or 160,000km (100,000 miles)

• While battery life can vary, EV manufacturers are required to issue a warranty for at least 8 years or 10,000 miles
• Kia offers a battery pack warranty for 10 years or 100,000 miles
• Hyundai provides warranty coverage on EV batteries for the vehicle’s entire lifetime
• Tesla provides a warranty of 8 years or 120,000 miles
• An EV battery is expected to last 10-20 years depending on maintenance and care.

• Tesla, for instance, offers an eight-year battery warranty and coverage of between 100,000–150,000 miles depending on the specific model.

• Groupe Renault estimates that the lifespan of its batteries – for automotive use – is around ten years

Note that Renault is not a battery specialist, just a legacy automaker.

Spontaneous combustion

Note that gas tanks used to spontaneously combust in the past, but this is no longer the case.
