Energy storage liquid cooling systems generally consist of a battery pack liquid cooling system and an external liquid cooling system. The core components include water pumps, compressors, heat exchangers, etc. The internal battery pack liquid cooling system includes liquid cooling plates, pipelines and other components.
The internal battery pack liquid cooling system includes liquid cooling plates, pipelines and other components. This article will introduce the relevant knowledge of the important parts of the battery liquid cooling system, including the composition, selection and design of the liquid cooling pipeline.
Liquid-cooled battery energy storage systems provide better protection against thermal runaway than air-cooled systems. “If you have a thermal runaway of a cell, you’ve got this massive heat sink for the energy be sucked away into. The liquid is an extra layer of protection,” Bradshaw says.
Under the conditions set for this simulation, it can be seen that the liquid-cooling system can reduce the temperature rise of the battery modules by 1.6 K and 0.8 K at the end of charging and discharging processes, respectively. Fig. 15.
The battery is the main component whether it is a battery energy storage system or a hybrid energy storage system. When charging, the energy storage system acts as a load, and when discharging, the energy storage system acts as a generator set, and it can only discharge and store electricity within a certain temperature range [ 18, 19 ].
An efficient battery thermal management system can control the temperature of the battery module to improve overall performance. In this paper, different kinds of liquid cooling thermal management systems were designed for a battery module consisting of 12 prismatic LiFePO 4 batteries.
