6 FAQs about [Palau battery cooling technical parameters]

How to improve the cooling performance of a battery module?

Orthogonal analysis was conducted to investigate the influence of each variable on the cooling performance of the battery module. It was confirmed that increasing the number of channels was the most effective method for improving the cooling performance and reducing the pumping power.

How to maintain the average temperature of a battery module?

Based on this, a cooling plate with six channels was applied to both the top and bottom parts, and the top and bottom cooling showed sufficient cooling performance in maintaining the average temperature of the battery module below 45 °C. 1. Introduction

How does a cooling plate change the temperature of a battery module?

This is due to the fact that the pressure drop was minimized by widening the cooling path, while maintaining the same flow rate. As the channel width of the cooling plate increased, the average temperature of the battery module decreased; however, the temperature difference between the upper and lower parts of the module increased. Figure 5.

How does PCM cooling affect battery temperature?

In the case of PCM cooling, the PCM contributed to passive cooling due to its robust heat storage capacity, limiting the maximum battery temperature because the PCM did not completely melt. However, if the PCM fully melted, the maximum temperature of the battery would increase, similar to the fin cooling method.

Can a PCM reduce the temperature of a 18650 battery?

Wu et al. conducted an experimental study that combined a PCM, a heat pipe, and liquid cooling for a 18650 battery. As the discharge cycle of the battery increased at a 3 C-rate, the composite system reduced the maximum temperature by 28 °C or more than the single system.

What is the temperature difference between a battery and a cooling plate?

In addition, the average temperature difference between the upper and bottom regions of the battery increased by 0.27 °C, from 13.7 °C to 14.0 °C, while the width of the cooling plate channel increased from 15.3 to 23.3 mm.
