Solar photovoltaic (PV) is considered a very promising technology, and PV-lithium-ion battery energy storage is widely used to obtain smoother power output. In this paper, we propose a battery equalization circuit and control strategy to improve the performance of lithium-ion batteries.
With the advancement of EV technologies, lithium-ion (Li-ion) battery technology has emerged as the most prominent electro-chemical battery in terms of high specific energy and specific power. The Li-ion battery pack is made up of cells that are connected in series and parallel to meet the voltage and power requirements of the EV system.
Still, the peak power of the lithium-ion battery was meager. In contrast, the peak power of SC was very high, which was a very satisfactory solution because SC took full advantage of it and absorbed most of the high energy. In contrast, the lithium-ion battery is protected and absorbs very little of the peak power.
Being equipped with a lithium-ion battery energy storage system can solve the problem of unbalanced power supply in a PV power generation system, which is crucial to the stable operation of PV .
The SC’s absorption threshold needs to be lowered, and the lithium-ion battery will release less power, and the SC will release power faster. If the HESS absorbs energy at this time, increasing the SC’s threshold for absorption energy is necessary because the SC has no redundant SOC to absorb the excess energy.

The power supply can now sink and source current, simi-lar to a battery, and by changing the power supply output voltage, any battery state-of-charge condition can be quickly simulated.
Then, the ratio of the input voltage to the output current is as follows: I˙ O U˙ in = ZM ZSR+(ZS + R+ ZP)ZM + ZPZS (4) To have the load-independent output current, it must eliminate the effect of load R change on the output current. Obviously, the load-independent output current can be achieved when ZP = ZS = −ZM.
