NEW YORK: Putting speculation to rest, scientists at the Berkeley Lab led by an Indian American have quantitatively showed that electric vehicles can meet the daily travel needs of drivers longer than commonly assumed. It is generally assumed that EV batteries will be retired after the battery has lost 20 percent of its energy storage or power delivery capability.
The new study shows that the daily travel needs of drivers continue to be met well beyond these levels of battery degradation.
"There are two main reasons people are hesitant to buy an EV: first, they're unsure it will satisfy their mobility needs. And second, they're afraid the battery won't last the whole life of the car and they'll have to replace it for a lot of money," said Indian American Samveg Saxena who leads a vehicle powertrain research programme at Berkeley Lab.
Saxena and his team also analysed battery power fade and found that even after substantial loss in battery power capabilities performance requirements are still met.
