“…Fiber optic (FO) sensors are very promising for the monitoring of battery packages in automotive applications. Optical fibers have many advantages with respect to conventional electric cabling: they are electrically insulating and immune to electromagnetic noise; if compared to standard copper cables, they are much lighter; and finally, they are are resistant to corrosion and, if made of polymeric materials, they can resist aggressive chemical species such as hydrofluoric acid, one of the most common products of the decomposition of the cell electrolyte during thermal runaway events [44]. Moreover, the reduced thickness enables the monitoring of the individual cells of the battery package without adding significant size and weight to the system.…”

The electrification of passenger cars is one of the most effective approaches to reduce noxious emissions in urban areas and, if the electricity is produced using renewable sources, to mitigate the global warming. This profound change of paradigm in the transport sector requires the use of Li-ion battery packages as energy storage systems to substitute conventional fossil fuels. An automotive battery package is a complex system that has to respect several constraints: high energy and power densities, long calendar and cycle lives, electrical and thermal safety, crash-worthiness, and recyclability. To comply with all these requirements, battery systems integrate a battery management system (BMS) connected to an complex network of electric and thermal sensors. On the other hand, since Li-ion cells can suffer from degradation phenomena with consequent generation of gaseous emissions or determine dimensional changes of the cell packaging, chemical and mechanical sensors should be integrated in modern automotive battery packages to guarantee the safe operation of the system. Mechanical and chemical sensors for automotive batteries require further developments to reach the requested robustness and reliability; in this review, an overview of the current state of art on such sensors will be proposed.

“…The second is the temperature and rate characteristics, which determine the operating range of the battery to give full play of its capacity and life. The working conditions of vehicle are complex, different vehicle types, road conditions and temperature changes in four seasons have different requirements on the temperature characteristics and rate characteristics of battery [16,17]. The third is the power characteristic, which is also the key demand for the acceleration and climbing performance of electric vehicles.…”

With the rapid development of new energy vehicle technology, how to test and evaluate the performance of a traction battery has become a key issue in the field of new energy vehicle testing technology. Starting from the technical requirements of vehicle traction battery, this mini review introduces the key contents of battery performance test and evaluation from vehicle level and battery level respectively. Furthermore, based on the actual vehicle demand, the influence of electricity quality and feedback current on the performance of battery is introduced, and the feasibility of multi-stage reuse of traction battery is discussed.

“…Kriston et al. performed simultaneous thermal analysis (STA) with GC/MS and FTIR for graphite anodes and Li x Ni 1/3 Mn 1/3 Co 1/3 O 2 cathodes [6] . Their results suggested that thermal decomposition happens in series of chain reactions that run out of control resulting in fires or explosions [6] .…”

Besides high energy density, fast‐charging capability, and costs, safety of Li‐ion batteries is fundamentally important – even after long‐term usage or abusive conditions. In this paper, a new combination of accelerating rate calorimetry (ARC) coupled with a mass spectrometer (MS), as well as cell resistance and audio recording was applied to study commercial 18650‐type Li‐ion cells. This novel ARC‐MS setup allows following the electrochemical and thermal behavior simultaneously to the evolved gases during cell venting and thermal runaway. The tested cells were (i) unaged, (ii) aged by low temperature cycling (main mechanism: Li deposition), as well as (iii) overcharged. The aged and the overcharged cells show an early onset‐of‐self‐heating at 36 °C whereas the self‐heating started at 96 °C for the unaged cells. The rank of the time until explosion of the cells is in the order of overcharged cell
