To protect the environment and reduce dependence on fossil fuels, world is shifting towards electric vehicles (EVs) as a sustainable solution. The development of fast charging technologies for EVs to time increase operating range essential replace traditional internal combustion engine (ICE) vehicles. Lithium-ion batteries (LIBs) are efficient energy storage systems in EVs. However, efficiency LIBs depends significantly their working temperature range. huge amount heat generated during increases battery uncontrollably may lead thermal runaway, which poses serious hazards operation In addition, with high current accelerates aging seriously reduces capacity. Therefore, an effective advanced management system (BTMS) ensure performance, lifetime, safety LIBs, particularly under extreme conditions. this perspective, review presents state-of-the-art strategies charging. problems owing its impacts discussed. core part cooling such indirect liquid cooling, immersion hybrid based recently published research studies period 2019–2024 (5 years). Finally, key findings potential directions next-generation BTMSs toward proposed. This offers in-depth analysis by providing recommendations solutions develop reliable
