摘要

As electric vehicles (EVs) continue to grow in popularity and adoption, one of the critical challenges in their design and operation is the efficient management of heat generated by the battery and powertrain systems. Battery temperature significantly impacts the performance, safety, and longevity of EV batteries. Excessive heat can cause accelerated degradation, reduced energy density, or thermal runaway. As critical components like batteries and motors overheat, EV performance declines. Thermal management systems are essential to regulate temperatures, but cooling systems consume energy, potentially reducing overall vehicle efficiency. Temperature fluctuations affect battery charge/discharge efficiency, lower energy density, speed up degradation, and shorten battery lifespan. Design and test innovative cooling technologies like liquid cooling, phase-change materials, and heat pipes to regulate battery temperature and prevent overheating. Optimize the energy consumption of cooling systems to minimize efficiency loss, ensuring thermal management enhances vehicle performance without compromising overall energy efficiency. The process involves designing an advanced thermal management system for EV batteries by selecting cooling technologies like liquid cooling, phase-change materials (PCMs), and heat pipes. Key elements include simulating temperature regulation and energy efficiency to minimize power loss while enhancing battery life. Materials with high thermal conductivity, such as water–glycol mixtures, copper, and paraffin wax, are chosen for their heat dissipation properties.
