The core part of this review presents advanced cooling strategies such as indirect liquid cooling, immersion cooling, and hybrid cooling for the thermal management of batteries during fast charging based on recently published research studies in the period of 2019–2024 (5 years).
Therefore, an effective and advanced battery thermal management system (BTMS) is essential to ensure the performance, lifetime, and safety of LIBs, particularly under extreme charging conditions. In this perspective, the current review presents the state-of-the-art thermal management strategies for LIBs during fast charging.
The temperature of the module rises briefly to a maximum temperature of 30.4 °C at the beginning of charging and then drops rapidly. At the end of charging, the module temperature is 27.23 °C. It can be seen that the current commercial fast charging strategy has a low charging rate at all stages.
In the pre-charging period between 0 % and 22 % SOC, the maximum temperature of the LIBs rises rapidly to a critical high temperature of 45 °C. It is necessary to switch to another smaller holding current, which shortens the duration of charging the battery with a Maximum non‑lithium plating charging current of 1.9C (296 A).
The need for fast charging for EVs is becoming an important factor in promoting the transition from traditional vehicles to EVs, contributing to environmental protection and reducing dependence on fossil fuels. However, fast charging and ultra-fast charging also pose challenges for battery thermal management.
