Here, for the first time, a multi-level electrochemical-thermal coupling model is developed on an open-source CFD platform. Based on this model, we perform comprehensive simulations for the pulse heating process with various parameters and strategies from plate level to cell level to module level. In addition, two innovative heating strategies, namely varied rate pulse and hybrid pulse, are proposed, where the latter integrates the pulse heating and electric heating. Our main results show that the proposed hybrid pulse strategy can provide cells with an over 2.5 times faster heating rate from −20 °C to 0 °C and save nearly 60 % energy consumption compared to the single pulse heating at 6 C-rate, exhibiting a great prospect in circumventing the low-temperature effect. Besides, the internal temperature difference can be controlled. A high pulse frequency is suggested to achieve better temperature consistency within cells and avoid noticeable changes in the cell internal physical fields.</span></p></div>","PeriodicalId":36355,"journal":{"name":"Etransportation","volume":"19 ","pages":"Article 100307"},"PeriodicalIF":11.9,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139026975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The minimum load is primarily limited by the hydrogen to oxygen (HTO) from cross-diaphragm transfer and lye mixing, with HTO above 2.0% being a significant safety risk. Reducing the lye flow rate and pressure are effective while two of the few ways by regulating the operating parameters to improve the HTO thus extend the minimum load boundary, but will worsen electrolysis efficiency. Therefore, this study proposes a synergistic regulation strategy of pressure and lye flow rate: maximizing pressure and lye flow rate during high load period to ensure high electrolysis efficiency; adjusting lye flow rate and pressure during medium load period to ensure HTO≤2.0% and maximize the electrolysis efficiency; and reducing lye flow rate and pressure to a low level during the low load period to broaden the minimum load so as to improve overall efficiency of AWE system when loading with fluctuant green electric. This work elaborates the HTO routes, influencing factors and parameter optimization mechanism by building a system-level steady-state and dynamic gas purity model.

Thermal runaway propagation depends on many factors, e.g., cell spacing, intermediate materials, and the entire cell stack setup. Furthermore, the choice of cell chemistry plays a decisive role in the safety design of a battery system. However, many studies considering cell chemistry only focus on the cell level or neglect the energetic impacts of safety measures on system integration. This leads to a neglect of the conflict of objectives between battery safety and energy density. In this article, a comprehensive analysis of the thermal runaway propagation in lithium-ion batteries with NMC-811 and LFP cathodes from a Mini Cooper SE and Tesla Model 3 SR+ is presented. The focus is set on the identification of differences in battery safety, the derivation of safety requirements, and the evaluation of their impact on system integration.

Regarding cell energy, thermal runaway reaction speed is nine times faster in NMC-811 cells and five times faster considering the whole propagation interval than LFP cells. However, since LFP cell chemistries have significantly lower energy densities than ternary cell chemistries, it must be verified whether the disadvantages in energy density can be compensated by advanced system integration. An analysis of cell-to-pack ratios for both cell chemistries has revealed that, based on average values, the gravimetric disadvantages are reduced to 16%, and the volumetric disadvantages can be completely compensated for at the pack level. However, future research should further focus on this issue as an accurate safety-related design depending on cell chemistry could enable a cost–benefit evaluation under the constraints of safety standards in the development of batteries for electric vehicles.</p></div>","PeriodicalId":36355,"journal":{"name":"Etransportation","volume":"19 ","pages":"Article 100305"},"PeriodicalIF":11.9,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590116823000802/pdfft?md5=4bcb8239bce76b7beb42decbdd4faa44&pid=1-s2.0-S2590116823000802-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138715166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
