“…Firstly, at the same temperature, the impedance arcs contract with increasing current amplitude, which is related to the solid electrolyte interphase (SEI)/cathode electrolyte interphase (CEI) processes and the charge transfer process. According to our previous research [37], the resistances of the SEI/CEI processes and the charge transfer process decrease with increasing current amplitude at low temperatures, which leads to the contraction of the impedance arc. Secondly, as the temperature decreases, the SEI/CEI processes and the charge transfer process slow down, causing the corresponding frequencies to decrease.…”

Bidirectional pulsed current (BPC) heating has proven to be an effective method for internal heating. However, current research has primarily focused on the impact of symmetrical BPC on battery heat generation, while neglecting the influence of different BPC parameters. To address this gap, this paper investigates the effects of various BPC parameters on battery heat generation. Initially, an electro-thermal coupled model of the battery is constructed based on the results of electrochemical impedance spectroscopy (EIS) tests conducted at different temperatures and amplitudes at 20% state of charge (SOC). The validation results of the model demonstrate that the absolute errors of voltage and temperature are generally less than 50 mV and 1.2 °C. Subsequently, the influence of BPC parameters on battery heat generation is examined under different terminal voltage constraints, temperatures, and frequencies. The findings at 20% SOC reveal that symmetrical BPC does not consistently correspond to the maximum heating power. The proportion of charge time and discharge time in one cycle, corresponding to the maximum heating power, varies depending on the charge and discharge cut-off voltages. Moreover, these variations differ across frequencies and temperatures. When the terminal voltage is constrained between 3 V and 4.2 V, the maximum heat power corresponds to a discharge time share of 0.55 in one cycle. In conclusion, the results underscore the complex relationship between BPC parameters and battery heat generation, which can further enhance our understanding of effective heating strategies for batteries.

“…The feasibility of alternating current (AC) preheating in battery systems has been verified by setting alternative pulse currents through batteries. 151 , 152 Joule heat can be generated for preheating. Previous experimental results indicated that a high current amplitude was beneficial for temperature uniformity, and that the LIB performance did not degrade significantly.…”

“…To achieve accurate estimation of the internal state of the battery during driving, nonintrusive nondestructive testing techniques centered on characteristic signals or reaction mechanism models have become a hot research topic. [88] Dai et al [89,90] conducted a systematic study of battery electrochemical impedance spectroscopy (EIS) to characterize the internal aging phenomenon of batteries using EIS properties and combined with machine learning algorithms to achieve accurate estimation of battery SOH. Xiong et al, [91] on the other hand, target the difficult problem of battery performance estimation at low voltages by using the solid-phase diffusion equation based on the surface SOC to describe the open-circuit voltage variation of the battery, combined with an equivalent circuit model to achieve the battery state estimation at low SOC.…”

Under the global carbon neutrality initiative, carbon emissions from the transportation sector are becoming increasingly prominent due to the growth in vehicle ownership. And electric mobility may be a potentially effective measure to reduce road traffic carbon emissions and achieve a green transformation of transportation. This paper systematically collates the relevant carbon accounting standards for the automotive industry and elaborates the current status of road transport greenhouse gas emissions by combining the data from the International Energy Agency. And by comparing the lifecycle carbon footprint of various energy types of vehicles, the necessity and feasibility of electric mobility to reduce carbon emissions are discussed. However, the comparison of vehicle lifecycle carbon footprints shows that electric vehicles (EVs) are not as environmentally friendly as expected, although they can significantly reduce road traffic carbon emissions. The high carbon emissions from the manufacturing process of the core components of EVs, especially the power battery, reduce the low‐carbon potential of electric mobility. Therefore, the carbon emission reduction strategies and outcomes of automakers in the automotive industry chain have been further reviewed. Finally, focusing on vehicle power batteries, this article reviews the technologies such as refined management and echelon utilization that can make EVs more environmentally friendly and promote carbon neutrality in the transportation sector.
