“Engineers made minor changes to the material composition of the battery cell chemistry, resulting in improved performance and durability,” GM said in a statement.
Battery capacity has been increased from 16 kilowatt-hours to 16.5 kWh, which means charging times are also up slightly. Chevy says a full charge on a 120-volt outlet could take 10.5 hours and 4.25 hours on a 240-volt outlet, up slightly from previous charging times, which ranged from four to 10 hours.
Volt owners have driven more than 65 million miles since the vehicle launched in 2010, according to Chevy, and about two-thirds of those miles were powered by electricity.
