| Abstract Rechargeable Li-ion batteries (LIBs) have considerably advanced in enabling electric vehicles compared to other battery chemistries, e.g., lead acid. However, a key challenge in LIB technology is the appropriate thermal management of battery cells, essential for ensuring battery safety, e.g., avoiding battery explosion or thermal runway events and maximizing the battery's life. The battery thermal management system (BTMS) controls individual cells' temperature, keeping them in the allowable range. This paper reviews the different kinds of BTMS, such as air, liquid, phase change material, heat pipe, and thermoelectric element cooling. In addition, hybrid systems that combine two or more cooling methods compare these technologies with power consumption methods (i.e., active or passive cooling) and state the advantages and disadvantages of each technology. Moreover, it focused on the cooling technologies considered for commercial use, i.e., if the automotive suppliers utilize them for experimental and theoretical studies. Most importantly, it identified several critical gaps that need further exploration, summarized BTMS technologies, and pinpointed directions of future work that would help researchers enhance the design of BTMS and their suitability for commercial purposes. | ||
