Study finds splitting fast charging into stages with pauses reduces battery wear

Researchers published a study in Batteries finding that splitting a fast charge into six two-minute stages at high intensity, separated by one-minute pauses, reduced the aging of commercial lithium-ion cells. After 1,009 cycles, those cells retained more than 84.7% of their capacity, compared with a drop below 80% around cycle 217 under continuous charging. The tests used individual cells, not cars on the road.

In 35 seconds

  • The six-stage protocol of two minutes with one-minute pauses showed the greatest resistance to aging among those tested.
  • After 1,009 cycles, the cells retained more than 84.7% of their capacity; under continuous charging they fell below 80% around cycle 217.
  • The tests used 48 commercial 20-ampere-hour cells with nickel-manganese-cobalt and graphite chemistry, not vehicles in operation.
