However, the internal environment of lithium-ion batteries is overwhelmingly harsh, and implanting metallic devices such as thermocouples may contribute to significant damage to the battery. Therefore, an effective way to overcome these difficulties is to implant a fiber optic temperature sensor inside the battery.
A novel fibre sensing technology is proposed to deliver a distributed, real-time and accurate measure of temperature for battery cell. The thermal behaviour of a pouch cell is experimentally investigated over a wide range of ambient temperatures and electrical load currents.
