The appeal of electric vehicles is pretty obvious: seemingly effortless acceleration, quiet operation, lower running costs, and zero tailpipe emissions. But an EV battery still wears down over time, and new research suggests aggressive driving may speed up that process.

A new Scientific Reports study found that aggressive driving was associated with greater model-predicted battery capacity fade than eco-driving.

Learn why driving style matters and how EV drivers can reduce unnecessary battery stress.

Does Aggressive Driving Drain an EV Battery Faster?

Yes, aggressive driving can use an EV’s stored energy faster and may also contribute to faster battery aging over time. Range and battery aging are separate effects, with driving habits influencing both in different ways.

“As with conventional vehicles, the efficiency and driving range of electric drive vehicles varies substantially based on driving conditions and driving habits,” according to the U.S. Department of Energy’s Plug-In Electric Vehicle Handbook for Consumers, published through its Clean Cities program.

Researchers from Shanghai Dianji University analyzed real-world data from 15 battery-electric vehicles in Guangzhou, China, using a physics-based model to separate driving behavior from other factors.

Those researchers found aggressive driving was associated with more than 2.5 times higher model-predicted capacity fade than eco-driving. The study didn’t track years of directly measured capacity loss, however. Its battery-aging findings came from a semi-empirical model, and all vehicles were the same model, so the results don’t establish how every EV battery will respond.

Hard acceleration requires the battery to deliver more power, while higher speeds increase the energy needed to overcome air resistance.

“High driving speeds reduce range because more energy is required to overcome the increased air resistance,” according to the handbook. “Aggressive driving—rapid acceleration and deceleration—reduces range compared with smooth acceleration and deceleration. In addition, hauling heavy loads and driving uphill reduces range.”

Other factors affect battery aging, too. Experts cite temperature, charging and discharging rates, storage conditions, and cycling patterns among the variables that influence battery life.

How EV Drivers Can Reduce Battery Stress

Drivers don’t have to avoid every hard acceleration. The bigger concern is regularly speeding up and slowing down aggressively.

A smoother driving style can help. Gradual acceleration puts less demand on the battery, and keeping a steady speed can help an EV use less energy. Leaving more room in traffic can also cut down on hard braking followed by another quick burst of acceleration.

Many EVs also have eco or efficiency modes that make the accelerator less sensitive. Drivers can use those settings if they find it difficult to keep acceleration smooth. Following the vehicle manufacturer’s recommendations for charging and battery care can help, too.

The study didn’t examine what happens after a single hard acceleration. Its findings instead point to overall driving style as something that may affect battery aging over time.
