Charge and discharge rate of liquid-cooled energy storage system

Why is a liquid cooling system more suitable for a high discharge rate?

This indicates that the cooling water takes away more heat when the battery module discharges at a rate of 2C, which means that the liquid cooling system is more suitable for the conditions of discharge at a high rate.

What is the discharge rate of a battery module?

3.1.1. N T, T max and Δ T max The battery module is discharged at a rate of 2C. Four types of liquid cooling systems are used, with a flow rate of 30 L/h and an inlet temperature of 20 °C. The N T, T max and Δ T max in the discharge process are obtained, as shown in Fig. 5. Fig. 5. The N T, T max and Δ T max of four types of cooling systems.

Can a liquid cooled battery module handle thermal propagation?

Conclusions In this paper, the thermal management and suppression of thermal propagation in a lithium-ion battery module with a liquid-cooled shell were investigated through experiments. It has been demonstrated that the presented liquid-cooled shell can meet the demands of battery module thermal management at high charging and discharging rates.

Which liquid cooling system should be used if a battery module is discharged?

When the battery module is discharged at a rate of 2C, the flow rate is no less than 12 L/h. In addition, when the range of flow rate is 12 ∼ 20 L/h, Z-LCS, F1-LCS or F2-LCS should be adopted. When the range of flow rate is higher than 20 L/h, four kinds of liquid cooling systems can be used.

Is liquid cooled shell suitable for battery module thermal management?

It has been demonstrated that the present liquid-cooled shell is capable of meeting the demands of battery module thermal management and maintaining battery module charging and discharging within acceptable temperatures.

Does liquid cooled shell have good performance during battery charging and discharging?

Considering the heat dissipation and temperature uniformity properties of the novel liquid-cooled shell structure, it can be concluded that it has good performance during battery charging and discharging. Figure 5. The change in battery module temperature with different discharge and charge rates.
