“…Recently, the BATTERY 2030 + proposed the smart batteries concept, which is based on newly embedded sensors for monitoring status changes in real time. Currently, the temperature of the LIBs has been measured by using different methods, such as thermocouple [13][14][15][16], thermo-resistive [17][18][19][20][21], infrared camera [22][23][24][25][26][27], and optical fibre [28][29][30][31][32]. It is a critical challenge to obtain internal measurement that harsh electrochemical environment, the particular packaging structures and the excellent performance of the LIBs.…”

The safety of lithium-ion batteries is an essential concern where instant and accurate temperature sensing is critical. It is generally desired to put sensors inside batteries for instant sensing. However, the transmission of internal measurement outside batteries without interfering their normal state is a non-trivial task due to the harsh electrochemical environment, the particular packaging structures and the intrinsic electromagnetic shielding problems of batteries. In this work, a novel in-situ temperature sensing framework is proposed by incorporating temperature sensors with a novel signal transmission solution. The signal transmission solution uses a self-designed integrated-circuit which modulates the internal measurements outside battery via its positive pole without package breaking. Extensive experimental results validate the noninterference properties of the proposed framework. Our proposed in-situ temperature measurement by the self-designed signal modulation solution has a promising potential for in-situ battery health monitoring and thus promoting the development of smart batteries.
