Structural diagram of liquid-cooled energy storage module

What are liquid cooling systems for large battery modules?

The liquid cooling (LC) systems for large battery modules commonly involve many LC plates (LCPs) or other cooling components for achieving a high cooling efficiency. This leads to a greatly reduced energy density of the battery modules, and raises the cost of the cooling system.

What is a simple liquid cooling (LC) structure?

A simple liquid cooling (LC) structure with only two LC plates (LCPs) is proposed. The precisely-tailored LCPs and optimized structure relieve the “edge-overcooling”. The LC structure shows excellent cooling performance for the 700 Wh battery module. The simple LC structure only accounts for 16.4 wt% of the module weight.

Can a liquid-cooled shell provide good thermal management of a battery module?

The experiments verified that the new liquid-cooled shell with optimal inlet/outlet configuration can provide good thermal management of the battery module. In this paper, a new type of liquid-cooled shell structure is proposed, as shown in Fig. 18.1.

What is a liquid cooled shell structure?

In this paper, a new type of liquid-cooled shell structure is proposed, as shown in Fig. 18.1. The liquid-cooled shell is equipped with 4 × 5 through-holes to accommodate 18,650 Li-ion batteries, with multiple horizontal and vertical flow channels built in between the batteries.

Does liquid cooled shell structure improve battery charging and discharging performance?

It can be seen that the new liquid-cooled shell structure has good heat dissipation and temperature equalization performance in the battery charging and discharging process. The variation of cell module temperature, temperature difference, and inlet/outlet pressure drop with coolant flow rate is shown in Fig. 18.4.

What is a three-dimensional physics model for a battery module?

Based on the finite element method, a three-dimension coupled with multiphysics model is applied for the battery module during the discharge process.
