Thermal Side Reaction on Lithium-Ion Battery in Fast Charging Mode with Multi-Stage Constant Current and Voltage Control CC-CV Charging Vechnique

Lithium-ion batteries are extensively used in fast charging stations because of their high density of energy storage and power. It is critical to know how to charge lithium batteries since their structure is very sensitive to heat. When using fast charging techniques for charging batteries, considerable heat is generated. This heat is caused by the ohmic losses of the battery and its internal reactions. While fast charging reduces the charging time of the battery, it may damage its structure. There are various methods of fast charging. Each has its advantages and limitations. By applying changes to the multi-stage constant current charging method, in addition to reducing the charging time, attempts were made to prevent damage to the battery. This improved method can deal with cases where temperature effects are removable, such as when there is a ventilation system. It minimizes charging time as much as possible.
