The technical challenges and difficulties of the lithium-ion battery management are primarily in three aspects. Firstly, the electro-thermal behavior of lithium-ion batteries is complex, and the behavior of the system is highly non-linear, which makes it difficult to model the system.
This system has the energy storage device which can be introduced by lithium-ion (li-ion) battery banks. Lithium-ion is mostly popular because of its high capacity and efficiency. Nevertheless, li-ion battery needs protective mechanism to control overcharged or undercharged of the cell that can reduce the life expectancy and efficiency.
The charging under constant current-mode continues until the whole battery voltage passes to a maximum allowed voltage, which is 4.2 Ns, where “Ns” is the unit that corresponds to the number of balanced cells in series. However, for the Li-ion batteries, 4.20 V is the highest voltage that can be used [ 6 ].
For automotive power batteries, the lithium-ion battery is considered to have reached the cutoff condition when SOH decays to 80%. (2) S O H = R e − R R e − R b × 100 % where R e and R b denote the internal resistance at the end of life of the Li-ion battery and the initial internal resistance of the new battery, respectively.
Previous studies have intensively discussed several methods for charging Lithium-ion batteries. The most practiced method is constant current– constant voltage (CC–CV) [ 1, 2, 3 ]. In this technique, the battery is first charged to some specified constant current set by the manufacturer whose value ranges from 0.5 to 1 C (Coulomb).
The charge current is reduced as the load is increased to main-tain the input at 4.5 V. As the load is reduced, the system returns to normal operation. The output voltage powering the system will drop if the system load current and the battery charge current exceed the available input current.
