High charging rates can generate significant heat, potentially causing the battery temperature to rise rapidly, which in turn may affect its performance and lifespan . Batteries have higher charging efficiency at appropriate temperatures, while their charging efficiency decreases at temperatures that are too high or too low.
Traditional fast charging methods usually entail charging the battery with high currents. Nonetheless, prolonged high-current constant charging can cause a progressive rise in battery temperatures. Excessive temperature can shorten the lifespan of LIBs, leading to decreased battery performance and driving range .
More and more researchers are exploring fast charging strategies for LIBs to reduce charging time, increase battery longevity, and improve overall performance, driven by the growing popularity of EVs. Nevertheless, fast charging poses challenges such as energy wastage, temperature rise, and reduced battery lifespan.
Insufficient charging time can result in incomplete charging or battery damage due to excessive charging current, leading to a chemical imbalance within the battery. Conversely, an excessively long charging time may cause overcharging issues.
2.5.2. High temperature High temperatures pose several adverse effects on Lithium-ion batteries, resulting in reduced capacity, decreased power output, and accelerated self-discharge. These adverse impacts might significantly affect the overall performance and reliability of the battery.
The primary source of heat generation within these batteries stems from the exothermic reactions and ohmic losses occurring in the solid and electrolyte phases during the charging and discharging processes. This increase in temperature within the battery cell is due to the interplay of thermal effects within the cell.
