“…Thereby, the used materials as well as the processing methods need to be considered for reliable and reproducible long term operation. Several studies use polyimide materials as support material or protective coating due to its very good thermal conductivity and chemical stability in polar aprotic solvents [333][334][335].…”

This review provides an overview of new strategies to address the current challenges of automotive battery systems: Intelligent Battery Systems. They have the potential to make battery systems more performant and future-proof for coming generations of electric vehicles. The essential features of Intelligent Battery Systems are the accurate and robust determination of cell individual states and the ability to control the current of each cell by reconfiguration. They enable high-level functions like fault diagnostics, multi-objective balancing strategies, multilevel inverters, and hybrid energy storage systems. State of the art and recent advances in these topics are compiled and critically discussed in this article. A comprising, critical discussion of the implementation aspects of Intelligent Battery Systems complements the review. We touch on sensing, battery topologies and management, switching elements, communication architecture, and impact on the single-cell. This review contributes to transferring the best technologies from research to product development.

“…Temperature inhomogeneities inside a battery can be measured with an instrumented cell with in situ measurement techniques during operation. [ 11–13 ] They can be induced by the inhomogeneous inner heat transfer paths and the anisotropic properties, caused by the layered structure of the electrode stacks, [ 14,15 ] with their typical combination of materials with high and low heat conductivity. [ 16 ] Furthermore, external conditions, such as the cooling system, can cause temperature inhomogeneities on the surface and within the cell.…”

Herein, a comprehensive experimental studies on the interdependence of temperature and current distribution in lithium‐ion batteries is presented. Initially, a method for measuring the current distribution on a single cell is presented and verified by comparison with measurements on a parallel circuit. The presented method is straightforward and robust. It provides accurate quantitative and reproducible results. They are consistent with literature and show a higher current with increasing temperature. This temperature dependency is more pronounced at lower temperatures. Furthermore, it offers the opportunity to determine the influence of the temperature on the current distribution more precisely. Finally, this publication correlates the normalized current with temperature quantitatively using an Arrhenius‐like approach according to I∼exp(−1T).

“…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.…”

“…Only a few methods have been applied to measure internal temperature of the pouch and cylindrical cells [16-18, 31, 32]. For the thermocouple [16] and thermo-resistive [17,18], the soft thin-film sensors with good chemical and thermal stability were preferred for avoiding physical damage to the electrodes and separators. The optical fibre was used to measure the internal temperature of 18,650 battery that placed in the centre of jelly roll [31,32].…”

“…So, electrochemical stability and accurate temperature measurement are need to be urgently solved. Recently, a novel embedded method was developed by Chen et al [18] that a small region of the active materials on the positive was removed for placing the thin film sensor. The configuration can weaken effect of the sensor on the capacity loss and damage of the active materials.…”

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.
