Abstract

To enhance the temperature uniformity of the battery pack within a safe range and reduce energy consumption

a novel waveform channel is designed based on the underdamped second-order system unit step response curve. Using a 1p12s(1 parallel and 12 series)590 module with square ternary lithium as the core

a steady-state analysis of a single-factor experiment is conducted under the condition of 2C discharge at 25 ℃ using the computational fluid dynamics(CFD)numerical calculation method. The relationship between fluid flow velocity

waveform frequency

damping

interval

liquid cooling plate cooling performance

and fluid pressure drop is investigated. Suitable parameters are selected through single-factor experiments to design orthogonal experiments. Range and variance analyses are then conducted to determine significant factor combinations and calculate the optimal combination based on comprehensive performance indicators. The results show that the maximum temperature is positively correlated with the damping and interval

and negatively correlated with the flow velocity and frequency. The maximum temperature difference is positively correlated with the interval

and negatively correlated with the flow velocity and frequency

with decreasing impact levels. Damping initially decreases and then increases its impact. Pressure drop is positively correlated with flow velocity and frequency

and negatively correlated with damping and interval. The orthogonal experiment analysis reveals that the optimal factor combination is a waveform channel with a frequency of 4

damping of 0.03

and interval of 1. The maximum temperature

maximum temperature difference

and pressure drop are 35.368 ℃

2.125 ℃

and 6.121 kPa

respectively. In comparison to the original cosine channel

these values increase by 1.99%

decrease by 42.61%

and decrease by 39.96%

respectively. By adjusting the parameters of frequency

damping

and interval

the heat transfer efficiency of the liquid cooling plate and the temperature uniformity of the battery pack are significantly improved

enhancing the stability and lifespan of the battery pack while reducing energy consumption. The flexible adjustment of the parameters of these three factors provides insights for application in various engineering scenarios.
