This is when reduction in driving range becomes noticeable year by year (See also BU-1003: Electric Vehicle, Figure 5) Figure 1: Energy band of aging EV battery. A new battery has plenty of grace capacity that is gradually being depleted. Higher charge levels and a deeper discharge maintain the driving range but stresses increase.

Battery aging implies performance degradation of the battery itself. In particular, the battery aging causes capacity reduction and internal resistance increase. The capacity reduction mainly affects the energy that the battery can deliver in each cycle, while the increase of the internal resistance limits the power that the battery can
