This paper proposes an integrated battery life loss modeling and anti-aging energy management (IBLEM) method for improving the total economy of BESS in EVs. The
Deep discharge depth increases BESS energy consumption, which can ensure immediate revenue, but accelerates battery aging and increases battery aging costs. The proposed BESS management system considers time-of-use tariffs, supply deviations, and demand variability to minimize the total cost while preventing battery aging.
Cycling-induced aging tests with different depth of discharge (DOD) and mean state-of-charge (SOC) are performed to verify the accuracy and robust of the proposed estimator. The average errors of the tested batteries are all less than 1.5%, which shows a good performance on accuracy and robustness.

In addition, cells that aged at 3.8 V lost around 18 % of their capacitance at 60°C and 40 % at 70°C. However, their resistance increase was significant, reaching 95 % at 70°C and 60% at 60°C after 17 months of aging. As a result, swelling of these LiCs was noticed so their aging tests were interrupted after 17 months.

Energy storage device testing is not the same as battery testing. There are, in fact, several devices that are able to convert chemical energy into electrical energy and store that energy, making it available when required. Capacitors are energy storage devices; they store electrical energy and deliver high specific power, being charged, and
