Battery pack age, and capacity loss
This is called "capacity loss" meaning the battery pack holds fewer kiloWatt-hours than when it was new, and that means the electric car will have less driving range.

Capacity fading in Li-ion batteries occurs by a multitude of stress factors, including ambient temperature, discharge C-rate, and state of charge (SOC). Capacity loss is strongly temperature-dependent. Aging rates increase as temperatures rise or fall above or below 25 °C. Capacity loss is C-rate sensitive and higher C-rates lead to a faster capacity loss on a per cycle. Chemi

A pack should be replaced when the capacity drops to 80 percent; however, the end-of-life threshold can vary according to application, user preference and company policy.
