Most testing of cells and batteries takes place at low currents relative to the capacity of the battery (the ‘C’ rate), and consists of simple full charges followed by a full discharge.
This is not a good way to predict the life expectancy of EV batteries, especially for people who own EVs for everyday commuting, according to the study published Dec. 9 in Nature Energy. While battery prices have plummeted about 90% over the past 15 years, batteries still account for almost a third of the price of a new EV.
