What is a battery management system (BMS)?
The battery management system (BMS), including the battery thermal management system (BTMS), is considered an essential component for the monitoring and control of these state parameters to ensure the battery's safe and reliable operation.
What are battery thermal characteristics and temperature sensitivity?
Battery thermal characteristics and temperature sensitivity are outlined, emphasizing their performance impacts. Internal temperature monitoring technologies are highlighted for their role in accurate, real-time data acquisition. Internal temperature management strategies are introduced to optimize performance.
How does battery temperature management work?
Traditional battery temperature management has primarily relied on external control technologies such as air cooling, liquid cooling systems, and external low-temperature heating systems [172, 173]. These methods regulate temperature through thermal exchange between the battery casing and the environment.
Does internal temperature monitoring improve battery safety?
This demonstrates the positive role of internal temperature monitoring in enhancing battery safety, enabling preventative measures to be taken before the battery could potentially enter thermal runaway, thus significantly increasing the safety of the battery.
Do power batteries need temperature monitoring?
Currently, most of the temperature monitoring and thermal management of power batteries are carried out on the outer surface of the battery, lacking a comprehensive review of internal temperature monitoring and control of power batteries.
Can a battery be integrated with a temperature measurement system?
Integrating temperature measurement systems often requires physical modifications to the battery structure, which may weaken its stability. For example, inserting sensors might involve drilling holes or creating cavities within the battery cells, potentially leading to structural weaknesses and operational failures under stress.
