To extend EV battery life, avoid habits that speed up degradation

EV battery performance declines faster depending on how often drivers use DC fast charging, the power level used and exposure to hot climates, Engadget reported. Geotab analyzed telematics data from more than 22,700 vehicles across 21 EV models and found average annual degradation of 2.3 percent. Vehicles with higher fast-charging shares and frequent charging above 100 kW showed higher degradation. Hot regions also recorded greater annual battery wear.
