In the temperature monitoring of lithium-ion batteries, contact temperature measurement can provide more accurate and timely internal temperature information. Configuring smart sensors helps prevent safety incidents such as battery overheating, thermal runaway, or explosions .
Challenges of internal temperature control in power batteries Internal temperature control is considered a crucial factor for ensuring the performance and safety of power batteries, especially when subjected to extreme high or low temperatures.
Conversely, low temperatures increase battery internal resistance, reduce battery capacity and affect battery power output, especially in electric vehicles. Research has shown that the optimal operating temperature range for lithium-ion batteries is typically between −20 °C and 60 °C.
Therefore, fiber optic sensors have good application prospects for monitoring internal temperature changes in batteries and providing thermal runaway warnings. Recent research has proposed using FBGs as sensors to monitor the operating state of batteries, primarily measuring changes in internal temperature, strain, and pressure states.
The temperature of the lithium-ion battery is a crucial measurement during usage for better operation, safety and health of the battery. In-situ monitoring of the internal temperature of the
