In recent years, energy and environmental issues have become more and more prominent, and electric vehicles powered by lithium-ion battery have shown great potential and advantages in alleviating these issues. Compared with other batteries, lithium-ion batteries have the advantages of high specific energy, high energy density, long endurance, low self-discharge and long shelf life. However, temperature of the battery has become one of the most important parameters to be handled properly for the development and propagation of lithium-ion battery electric vehicles. Both the higher and lower temperature environments will seriously affect the battery capacity and the service life. Under high temperature environment, lithium-ion batteries may produce thermal runaway, resulting in short circuit, combustion, explosion and other safety problems. Lithium dendrites may appear in lithium-ion batteries at low temperature, causing short circuit, failure to start and other operational faults. In this paper, the used thermal management methods of lithium-ion batteries are introduced and their advantages and disadvantages are discussed and compared. At the same time, the prospect of future development is put forward.

“…The energy conservation equation of the continuous phase is as follows 33 :

\frac{\partial}{∂t} ((), ρ_{a} c_{normalp, normala} T_{a}) goodbreak+ \nabla \cdot ((), ρ_{a} c_{normalp, normala} \overset{v}{true} T_{a}) goodbreak= goodbreak- \nabla \cdot ((), k_{a} \nabla T_{a})

The momentum conservation equation of the continuous phase is as follows:

\frac{\partial ρ_{a}}{∂t} goodbreak+ \nabla \cdot ((), ρ_{a} \overset{v}{true} \overset{v}{true}) goodbreak= goodbreak- \nabla P

The continuity equation of the continuous phase is as follows:

\frac{\partial ρ_{a}}{∂t} goodbreak+ \nabla \cdot ((), ρ_{a} \overset{v}{true}) goodbreak= 0

The thermal management system has essential effects on the performance, life, and consistency of lithium-ion batteries. Compared with commonly used cooling methods, spray cooling has excellent performance and is now widely used in electronic equipment, metal processing, laser surgery, and other fields.However, there are few applications of spray cooling in the battery thermal management systems (BTMSs). With the increase of the charge and discharge speed and people's rising attention to the thermal runaway accidents of electric

Optimization Investigation on Air Phase Change Material Based Battery Thermal Management System

To ensure the normal operation of a battery pack, a battery thermal management system (BTMS) is required to control the temperature of batteries. Herein, the method using an artificial neural network (ANN) combined with a genetic algorithm (GA) is proposed to optimize the thermal performance of air phase change material (PCM) cooling based BTMS. The ANN is applied to describe the relationship between BTMS parameters (inlet air velocity, inlet air temperature, PCM thickness, battery unit spacing, and discharge rate) and battery pack thermal characteristics. The results show that the PCM thickness and battery unit spacing have little effect on the battery temperature. Then, the optimal parameter combinations of BTMS are solved by GA with the goal of minimizing the maximum temperature. The maximum relative error between simulation and prediction is 0.484 °C, which is only 1.3835% of the simulated value. The optimal parameter combinations help to slow down the temperature rise of the battery pack and delay the phase transition of PCM. The results indicate that the developed model can accurately describe the relationship between the BTMS parameters and battery temperature, which provides a time‐saving and efficient method for the optimal design of BTMS.
