The reliability and efficiency of the energy storage system used in electric vehicles (EVs) is very important for consumers. The use of lithium-ion batteries (LIBs) with high energy density is preferred in EVs. However, the long range user needs and security issues such as fire and explosion in LIB limit the widespread use of these batteries.
Among all power batteries, lithium-ion power batteries are widely used in the field of new energy vehicles due to their unique advantages such as high energy density, no memory effect, small self-discharge, and a long cycle life [, , ]. Lithium-ion battery capacity is considered as an important indicator of the life of a battery.
The charge cut-off voltage of LIB is generally 4.2 V . Charge voltage above this value reduces the capacity and lifetime of the battery and causes safety vulnerability. Fig. 5 shows the graph of the change in the capacity and cycle life of the LIB at 4.2 V and above.
As known, the power batteries employed in EVs are composed of several single batteries. When a cell is utilized in groups, the performance of the battery will change from more consistent to more dispersed with the deepening of the degree of application. Because of the problem of battery consistency, the study of battery life is emphasized.
Flexible, manageable, and more efficient energy storage solutions have increased the demand for electric vehicles. A powerful battery pack would power the driving motor of electric vehicles.
