Why do batteries need to be cooled? Electric vehicles typically use lithium-ion batteries. The batteries must be operated within a "comfort zone". If the battery is not within this range, its life will be reduced. In addition, if the temperature is too low or too high, the battery cannot provide the required power.
This need for direct cooling arises due to the significant heat generated by the high current flowing into the battery during fast charging. Effective battery cooling measures are employed to efficiently dissipate excess heat, thereby safeguarding both the charging rate and the battery from potential overheating issues.
Electric vehicles depend on rechargeable batteries for mobility. As batteries supply electric power to the electric motors in electric vehicles, these batteries get heated and require some sort of thermal management system. The battery cooling system in electric vehicles regulates the temperature of the battery and other electronics systems.
The primary loop is similar to the passive liquid cooling system. The secondary loop is in the air conditioning loop. It consists of two heat exchangers that work as evaporators and condensers, respectively. A quick response from the battery cooling system in electric vehicles is essential for reliable electric drive mobility.
A substantial heat amount is generated during fast charging due to the high current flowing into the battery. If this heat isn't managed, it can impede the charging process or even cause damage to the battery. Effective cooling helps dissipate the excess heat, enabling faster and safer charging.
A liquid or air cooling system must manage this elevated heat without compromising safety or performance. Fast charging also demands cooling systems capable of rapidly dissipating generated heat to prevent overheating, a factor that could undermine battery longevity and safety.
The proposed cooling improves the temperature uniformity of the battery up to 57% and reduces the temperature rise of the battery to 14.8% with a rise in coolant flow rate from 652 mL/min to 1086 mL/min .
