Electric Car Battery Life: Everything You Need to Know, Including How Long They Last. The battery packs of electric vehicles are quite resilient, with the lithium-ion type used in most modern EVs...
This battery life calculator estimates how long a battery will last, based on nominal battery capacity and the average current that a load is drawing from it. Battery capacity is typically measured in Amp-hours (Ah) or milliamp-hours (mAh), although Watt-hours (Wh) is occasionally used.
Key Takeaways. Understanding kWh is crucial for optimizing energy storage. Battery capacity, voltage, current, and time are fundamental in kWh calculations. Different battery types require specific approaches for accurate kWh determination. Factors like temperature and depth of discharge influence kWh calculations.
The battery cycle life generally lies between 1000-5000 cycles, and the advanced batteries are less affected by discharge and environmental factors. This Jackery''s guide reveals everything about the battery life cycle and how to extend it.
While the motor may be the source that actually propels an electric vehicle, the battery pack is its virtual heart and soul. If you’re in the market for a new or used EV, you’ll want to pay attention to the battery’s specs, and be aware of other aspects that will ultimately affect its performance.
Electric vehicles use lithium-ion batteries of various design, similar to those used in cell phones and laptop computers, only on a much larger scale. Lithium-ion batteries have a high energy density and are less likely than other types of batteries to lose their charge when not being used.
Battery capacities of current EVs range from a mere 17.6 kWh in the Smart EQ ForTwo with a range of just 58 miles, up to 100 kWh in the Tesla Model S and Model X that can run for over 300 miles before needing a charge. Battery capacities and other pertinent specs for all current EVs can be found on our companion website InsideEVs . They’re also provided in each of the used EV listingshere on MYEV .
Perhaps the most critical factor to consider when shopping for an EV is the battery’s estimated range on a full charge, as rated by the Environmental Protection Agency. You can find data on battery range and energy consumption for all current and past models on the EPA’s fueleconomy.gov website. You’ll also find it on the pricing sticker that’s required to be affixed to the side window of every new vehicle sold in the U.S.
As with conventionally powered cars, EVs are tested for both their operating range and energy consumption under controlled conditions in a laboratory. They’re “driven” on a dynamometer, which is like a treadmill for cars, using multiple standardized driving schedules to simulate city and highway motoring. An EV begins testing with the battery fully charged, and is operated until it becomes fully depleted.
However, an EV’s actual range on charge can vary according to a number of factors. Lead-footed acceleration and driving at higher speeds will tend to use more kWh than would more mannerly around-town motoring. The battery will also drain at a quicker rate when operating with a full load of passengers and cargo. All else being equal, a heavier vehicle will consume more energy to reach and maintain a given speed than will a lighter one.
Most electric vehicle charging is done at home, either via a conventional 120-volt circuit (known as Level 1 charging) or a dedicated 240-volt line (Level 2 charging). Depending on the vehicle’s battery capacity it can take anywhere from eight hours to more than 16 hours to achieve a full charge using Level 1 charging.
Though it will cost a few hundred dollars to have an electrician install 240-volt service in your garage, it will pay off in terms of charging times as short as four hours. If your energy provider offers a discount for electricity tapped during off-peak hours, you can save money by scheduling a charge in the middle of the night.
There is an even quicker alternative, called Level 3 charging, though it’s limited to a small, but growing, system of public charging stations. Also referred to as DC Fast Charging, it can bring an EV’s battery up to 80 percent of its capacity in as little as 30 minutes, depending on the vehicle.
Be aware, however, that an EV’s battery will take longer to replenish in cold weather than it will at warmer temperatures no matter which level of charging is being used.
On the plus side, federal regulations require that an EV’s battery pack, which can cost thousands of dollars to replace, be covered under warranty for at least eight years or 100,000 miles. whichever comes first. For its part, Hyundai extends this to lifetime coverage on the Kona Electric, while Kia bumps it up it to 10 years or 100,000 miles on the Niro and Soul EV models.
Be aware, however, that every EV warranty contains exceptions with regard to battery life. For example, some automakers only cover the battery pack against total failure, while others, including BMW, Chevrolet, Nissan, Tesla (Model 3) and Volkswagen will replace it if it falls to a specified capacity percentage while under warranty, which is usually 60-70 percent.
Finally, if you’re buying or selling a used EV, keep in mind that any remaining part of the battery’s original warranty will transfer to a subsequent owner.
