In recent years, model-based and data-driven methods have been widely used for SOH estimation, but due to the uncertainty of battery charging conditions in practice, it is difficult to obtain a fixed local segment. In this paper, the charging curve is first divided into sev...
The general definition of open circuit voltage is only if battery relaxed for approximately more than 30 minutes. The battery voltage curve varies according to different loads, temperatures, ages, etc, so a static OCV table can’t represent the SOC. The SOC estimation cannot rely on the look ...
Accurate evaluation of Li-ion battery (LiB) safety conditions can reduce unexpected cell failures, facilitate battery deployment, and promote low-carbon economies. Despite the recent progress in artificial intelligence, anomaly detection methods are not customized for or validated in realistic battery sett...
L-curve is a popular graphical method for determining the suitable regularization parameter. L-curve33shows the negotiation between the two quantities as described in Eq. (6) and is used to find the regularization parameter. Secondly, this technique is fast and straightforward. Thirdly, computing t...
However, the complex physicochemical characteristics of battery degradation cannot be obtained directly. Here a novel Gaussian process regression model based on the partial incremental capacity curve is proposed. First, an advanced Gaussian filter method is applied to obtain the smoothing incremental ...

Li-S chemistry is regarded as a near-future battery technology that could deliver a specific energy more than 350 Wh kg−1, surpassing the state-of-the-art Li-ion battery (LIB) technology [1–3]. In contrast to the one-electron Li-ion chemistry, Li-S battery (LSB) features a two-...
Battery technology company Saft is looking to bring its Flex’ion li-ion battery systems to the Middle East. Oil Review speaks to Nick Finney, the company’s Li-ion business development and product manager, Industrial Standby Division. THE MIDDLE EAST is a critical market for Saft, which ...
