This paper provides a new way for the efficient thermal management of the automotive power battery.
Bulut et al. conducted predictive research on the effect of battery liquid cooling structure on battery module temperature using an artificial neural network model. The research results indicated that the power consumption reduced by 22.4% through optimization. The relative error of the prediction results was less than 1% (Bulut et al., 2022).
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.
To verify the effectiveness of the cooling function of the liquid cooled heat dissipation structure designed for vehicle energy storage batteries, it was applied to battery modules to analyze their heat dissipation efficiency.
Developing energy storage system based on lithium-ion batteries has become a promising route to mitigate the intermittency of renewable energies and improve their utilization efficiency. In this context, thermal management is needed to maintain battery temperature and thermal uniformity without consuming significant power.
The design is least sensitive to changing flow rates, especially when the inlet temperature of the coolant is similar to that of the surrounding. But the cooling solution maintains the operating temperature of batteries at discharge rates of 2C and 3C. Different configurations of the cooling channels promise to be a field of investigation.
PCMs are capable of storing a massive amount of thermal energy (TE) by a phenomenon termed as a change of phase from one to another (commonly used in building construction is based on the phase transformation from solid-liquid state and vice versa), at a specific narrow temperature range, and give away higher heat of phase transition (i.
Phase change material (PCM) thermal energy storage (TES) technology is a sustainable energy savings option that is especially lucrative in building energy management. PCM (s) can be applied directly for free cooling to reduce the building energy requirement for air conditioning.
Reutilization of thermal energy according to building demands constitutes an important step in a low carbon/green campaign. Phase change materials (PCMs) can address these problems related to the energy and environment through thermal energy storage (TES), where they can considerably enhance energy efficiency and sustainability.
Despite the advantages of inorganic class of phase change materials and their potential for a high temperature latent heat storage, there are some technical challenges (which are discussed throughout the article) that need to be addressed in the future work such as:
Summary and conclusions In this review work, inorganic phase change materials (iPCMs) have been discussed with their properties and key performance indicators for building integration. The selection of these iPCMs mainly depends on thermophysical properties, mechanical properties soundness during phase transition and compatibility.
The short duration of heat storage limits the effectiveness of TES. Phase change materials (PCMs) are a current global research focus due to their desirable thermal properties, which improve energy performance and thermal comfort. PCMs require relatively less synthesis effort while maintaining high efficiency and enhancing cost-effectiveness.
Inorganic phase change materials The family of iPCMs generally includes the salts, salt hydrates and metallics.

Inconsistent battery voltage data can be used to estimate the state of health of the battery. The dual timescale Kalman filtering algorithm based on the reference difference battery model is derived. A compensation algorithm for the voltage difference of the RC circuit in the battery difference model is proposed.
Cell difference model In series-connected batteries, the internal resistance and the maximum available capacity primarily affect the voltage response difference and correspond to the SOH of the battery. Therefore, assessing the difference in battery voltage response is a viable means of evaluating battery health.
Due to limitations (e.g., production techniques, tolerance levels, and material defects ), there may be subtle differences in parameters such as capacity, internal resistance, and self-discharge rate between batteries. In practice, these inconsistencies manifest in the inconsistent voltage responses of series-connected cells.
Estimating the battery state of health using voltage differences improves the speed and accuracy of the algorithm. The state-of-health (SOH) of battery cells is often determined by using a dual extended Kalman filter (DEKF) based on an equivalent circuit model (ECM).

For three types of liquid cooling systems with different structures, the battery's heat is absorbed by the coolant, leading to a continuous increase in the coolant temperature. Consequently, it is observed that the overall temperature of the battery pack increases in the direction of the coolant flow.
