Advancement of lithium-ion battery cells voltage equalization techniques: A review

Recently, the use of electric batteries has reached great heights due to the invention of electric vehicles (EVs). Many lithium-ion battery cells are usually connected in series to meet the voltage requirements. The voltages of the entire series-connected battery cells in a battery pack should be eq...

Computer science TK Electrical engineering. Electronics Nuclear engineering Recently, the use of electric batteries has reached great heights due to the invention of electric vehicles (EVs).

However, such result is impossible due to some unavoidable reasons in real life.
