Can liquid cooling reduce temperature homogeneity of power battery module?

Based on this, Wei et al. designed a variable-temperature liquid cooling to modify the temperature homogeneity of power battery module at high temperature conditions. Results revealed that the maximum temperature difference of battery pack is reduced by 36.1 % at the initial stage of discharge.

Are lithium-ion batteries temperature sensitive?

However, lithium-ion batteries are temperature-sensitive, and a battery thermal management system (BTMS) is an essential component of commercial lithium-ion battery energy storage systems. Liquid cooling, due to its high thermal conductivity, is widely used in battery thermal management systems.

What is a battery energy storage system?

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 ].

Are lithium-ion batteries safe for energy storage systems?

Lithium-ion batteries are increasingly employed for energy storage systems, yet their applications still face thermal instability and safety issues. This study aims to develop an efficient liquid-based thermal management system that optimizes heat transfer and minimizes system consumption under different operating conditions.

Are battery energy storage systems a viable solution?

However, the intermittent nature of these energy sources also poses a challenge to maintain the reliable operation of electricity grid . In this context, battery energy storage system (BESSs) provide a viable approach to balance energy supply and storage, especially in climatic conditions where renewable energies fall short .

Does low temperature affect battery performance?

However, low temperature will lead to an increase in internal resistance and a decrease in capacity, which in turn will lead to a decrease in battery performance [ 21 ]. Therefore, in order to achieve the best performance of the battery energy storage system, a proper battery thermal management system is required.
