Energy and environmental issues are more pressing than ever with the task of reducing carbon emissions and finding new fuel sources to replace fossil fuels. One of the directions that is in line with the requirements of the time is to develop electric cars using completely electrified batteries to replace gasoline. Considering their high energy density and lengthy cycle life, lithium-ion batteries are frequently utilized in electric cars. The personal and property safety of passengers is gravely threatened by the spontaneous combustion accidents of electric cars caused by the thermal runaway of lithium-ion batteries. Therefore, studies on early warning as well as solutions to overcome when a thermal runaway incident occurs have become increasingly important and urgent. The current study provides advancements in the thermal management, electrical management, and structural design of early warning battery thermal runaway applications in electric vehicles. This minireview aims to provide the most concise but complete information to provide an overview of the story of thermal runaway and development trends for early warning in the next decade.

The application of the minichannel cold plate in a cylindrical battery module encounters the problem of poor heat transfer capability as it cannot match well with the curved surfaces of the cylindrical batteries. Herein, design optimization of a minichannel cold plate is performed to enhance its heat dissipation performance in the cylindrical battery module. In‐depth analyses are made on the thermal behavior of a cylindrical battery module with minichannel cold plates. Influences of different cold plate design parameters, including the size and position of the heat transfer interface between the batteries and the cold plates, the cold plate material, and the cold plate thickness, are examined and compared under various coolant velocities. The results highlight the significance of cold plate design in achieving a high‐performance cooling system for the cylindrical battery module. Based on the results, some general rules are set for the design of minichannel cold plates in the cylindrical battery module, which can provide useful guidance for the future development of minichannel cold plates.

In this study, a novel indirect boiling cooling battery thermal management system with two‐phase coolant R141b is proposed for the commercial cylindrical lithium‐ion battery pack. The heat conduction blocks are used to enlarge the heat transfer area between batteries and straight round tubes, and the R141b coolant flows and boils inside tubes to remove heat generated from batteries. Three‐dimensional simulation models are built and used to study the influence of partial structural parameters (height of heat conduction blocks, number and diameter of round tubes), the flow pattern layout, the coolant flow rate, and the battery discharge rate on the cooling performance of BTMS. The results show that the cross‐flow layout significantly improves the temperature uniformity of the batteries, with the maximum temperature difference reduced by 30% compared to the concurrent flow. Meanwhile, the appropriate geometrical parameters can further improve both cooling capacity of the BTMS and the temperature uniformity of the batteries. When the optimized structure with a coolant flow rate of 0.1 L min−1 under the cross‐flow layout, the maximum temperature and maximum temperature difference of batteries discharged at 2C reduced to 38.6 and 3.81°C, which are 97% and 64% of those in the concurrent flow, respectively.This article is protected by copyright.
