| Abstract: | The widespread adoption of electric vehicles has raised higher demands for the technology related
to power batteries. Consequently, a thermal management system that keeps the battery within an optimal
temperature range has become a core technical requirement for major manufacturers. In recent years, the
focus has shifted towards low-temperature thermal management technology, driven by the performance
degradation and life decay of lithium-ion batteries in winter''s cold conditions. Based on the degradation
mechanism of lithium-ion batteries in cold conditions, the paper provides a comprehensive overview of the
development status of low-temperature thermal management systems. Additionally, in conjunction with the
latest research progress, it summarizes a set of evaluation methods for low-temperature thermal management
of electric vehicles. |
