Abstract
Thermal analysis and thermal management of lithium-ion batteries for utilization in electric vehicles is vital. In order to investigate the thermal behavior of a lithium-ion battery, a liquid cooling design is demonstrated in this research. The influence of cooling direction and conduit distribution on the thermal performance of the lithium-ion battery is analyzed. The outcomes exhibit that the appropriate flow rate for heat dissipation is dependent on different configurations for cold plate. The acceptable heat dissipation condition could be acquired by adding more cooling conduits. Moreover, it was distinguished that satisfactory cooling direction could efficiently enhance the homogeneity of temperature distribution of the lithium-ion battery.

Changes in working temperature of lithium-ion batteries effect electrochemical reactions
The three-dimensional CFD model of the cooling system was demonstrated concerning decreasing the highest temperature and temperature variation of the cooling system for the lithium-ion battery cell. The purpose of this investigation is to present a design approach of liquid cooling for the lithium-ion battery cell by including different conditions such as constructional parameters of the cooling system. In this investigation cold plate including several internal conduits in identical size as the lithium-ion battery cell were located between every two battery cells
The outcome shows that enhancing the homogeneousness of temperature distribution the highest temperature after 8C discharging gets to 33.28 C, 34.7 C, and 35.7 C
Summary
Changes in working temperature of lithium-ion batteries effect electrochemical reactions. This causes different regions of the battery cell to experience different electrochemical reaction rates. Temperature homogeneity is a new demand in design of thermal management systems for electric vehicle batteries. Lithium-ion batteries have the ability to emerge as an important part of future power demands, including electric vehicles [1]. When unaccompanied by an efficacious cooling system, the temperature of a lithium-ion battery increases attributable to heat collection. This might cause thermal runaway in the entire battery [2,3]
