What is a liquid-cooled battery energy storage system (BESS)?

High-power battery energy storage systems (BESS) are often equipped with liquid-cooling systems to remove the heat generated by the batteries during operation. This tutorial demonstrates how to define and solve a high-fidelity model of a liquid-cooled BESS pack which consists of 8 battery modules, each consisting of 56 cells (14S4p).

What is a liquid cooled system?

A liquid cooled system is generally used in cases were large heat loads or high power densities need to be dissipated and air would require a very large flow rate. Water is one of the best heat transfer fluids due to its specific heat at typical temperatures for electronics cooling.

What factors influence the thermal efficiency of liquid-cooled battery pack systems?

Various factors influencing the thermal efficiency of liquid-cooled battery pack systems were systematically examined. The primary findings demonstrated that the innovative design of a battery pack cooled by variable-temperature coolant could significantly decrease the maximum temperature variation inside the battery pack.

How does a liquid cooling system work?

Presently, the mainstream application of the liquid cooling system involves indirect contact cooling, which effectively removes battery heat through a liquid cooling plate , , . The liquid cooling system efficiently lowers both the overall temperature and the non-uniform temperature distribution of the battery module.

How to simulate air cooled and liquid cooled modules?

For simulating the air-cooled and liquid-cooled modules, the velocity-inlet and pressure-outlet are applied to the inlet and outlet of the computational domain. Moreover, the remaining walls are assumed to be in an adiabatic condition, and the initial temperature of the module for both BTMSs is assumed to be 25 °C.

What is liquid-cooling management system of a Li-ion battery pack (Ni-Co-Mn)?

In this study, a liquid-cooling management system of a Li-ion battery (LIB) pack (Ni-Co-Mn, NCM) is established by CFD simulation. The effects of liquid-cooling plate connections, coolant inlet temperature, and ambient temperature on thermal performance of battery pack are studied under different layouts of the liquid-cooling plate.
