EV Battery Degradation. The battery pack in your all-electric vehicle is made to last the lifetime of the vehicle. However, EV batteries will slowly begin to lose the amount of energy they can store over time. This phenomenon is called "battery degradation" and can result in reduced energy capacity, range, power, and overall efficiency.

For those who plan on keeping their Teslas for the long haul or buying second hand, the news is good. The data reveals that after 200,000 miles of use, these EVs retain an average of 85% of their original battery capacity. While the average degradation of 15% is noteworthy, it''s important to consider that this figure is just that – an average.
Battery life has been a crucial subject of investigation since its introduction to the commercial vehicle, during which different Li-ion batteries are cycled and/or stored to identify the degradation mechanisms separately (Käbitz et al., 2013; Ecker et al., 2014) or together.Most commonly laboratory-level tests are performed to understand the battery aging behavior under …
Considering the single degradation variable of the battery, the health state of the battery can be described as follows after a short time interval t p from the initial time t 0, (4) v (t 0 + t p, ε) = F (x 0, t 0, t p, μ (ϕ)) where F (·) is a function describing changes in battery status, μ is the function of ϕ, the battery degradation ...
Degradation is separated into three levels: the actual mechanisms themselves, the observable consequences at cell level called modes and the operational effects such as capacity or power fade. Five principal and thirteen secondary …
