Nice News - We already knew that electric vehicle batteries typically last longer
than the batteries in their gas-fueled counterparts. But thanks to a
recent study, we also now know that EV batteries may last up to 40% longer than researchers previously thought, meaning users could get an extra few years out of their packs and cars.
The
old info was based on lab tests where engineers evaluated batteries at a
constant rate of discharge. But a team at Stanford University
discovered that when EV cars are subject to real-life driving conditions, their power sources are more durable than the original labs showed.
“We’ve not been testing EV batteries the right way,”
study co-author Simona Onori said in a statement. “To our surprise,
real driving with frequent acceleration, braking that charges the
batteries a bit, stopping to pop into a store, and letting the batteries
rest for hours at a time, helps batteries last longer.”
Plus,
good news for drivers who like to put the pedal to the metal: It turns
out pressing the pedal hard with your foot doesn’t speed up aging, and
may actually slow it down.
