This article uses 3D computational fluid dynamics simulations to analyze the performance of a water-cooled system with rectangular channels for a cylindrical battery pack.
The liquid-cooled battery energy storage system (LCBESS) has gained significant attention due to its superior thermal management capacity. However, liquid-cooled battery pack (LCBP) usually has a high sealing level above IP65, which can trap flammable and explosive gases from battery thermal runaway and cause explosions.
For an electric vehicle, the battery pack is energy storage, and it may be overheated due to its usage and other factors, such as surroundings. Cooling for the battery pack is needed to overcome this issue and one type is liquid cooling. It has numerous configurations of cooling line layouts and liquid coolants used where the most optimum configuration is preferable to

Experimental setup The experimental apparatus of the liquid immersion cooling battery pack was shown in Fig. 14, which primarily consisted of three parts: the circulation system, heating system, and measurement system. The coolant was YL-10 and it exhibited excellent compatibility with all the materials and devices used in this experiment.
The graph sheds light on the dynamic behavior of voltage during discharge under liquid immersion cooling conditions, aiding in the study and optimization of battery performance in a variety of applications. The configuration of the battery and the direction of coolant flow have a significant impact on battery temperature.
To facilitate the observation of the temperature control process of the immersion cooling battery pack, the heating rods were initially heated to 35 °C before initiating the circulation of the coolant. The coolant inlet temperature was set to 25 °C (controlled by the thermostatic bath), and the coolant flow rate was sequentially adjusted.
The experimental apparatus of the immersion cooling battery pack was also developed to explore the heat dissipation and temperature uniformity at 2C discharge rate. The simulation results were in well agreement with the experimental results, with the deviation less than 0.43 °C when the flow rate exceeded 0.6 L/min.
In direct liquid cooling, the inlet temperature of the coolant has a significant impact on the electric performance of the battery. Cooling efficiency improves when the coolant inlet temperature is reduced in direct liquid cooling.
The study indicated that at 10C discharge rate, the maximum temperature of the battery pack was maintained around 65 °C, with poorer temperature uniformity (Δ Tmax exceeding 38 °C). According to the above research, the thermal performance of individual cells or small-scale battery packs with limited cell counts has been widely investigated.
