Liu and Chen used three features as HFs during the constant current (CC) and constant voltage (CV) charging, which were the charging time interval of voltage varying from 3.9 to 4.2 V, the charging voltage varying from 3.9 V to the voltage after 500 s, the CV charging current drop between 1.5 A (the CC charge current) and the current after 1000 s, respectively.
The evolution of lithium battery technologies holds great promise for a wide range of applications, including EVs. Lithium batteries offer exceptional specific power, specific energy, and an impressive energy density of 350 Wh/L, all packed into a compact and lightweight design (Koohi-Fayegh and Rosen, 2020, Tomar and Kumar, 2020).
Accurate performance evaluation of lithium-ion battery is crucial for its detection, screening and echelon utilization. However, existing evaluation methods rely on specific or complex tests, leading to limited flexibility and high time costs. To address these challenges, a novel two-stage approach based on random charging curve is proposed to …

Charging properly a lithium-ion battery requires 2 steps: Constant Current (CC) followed by Constant Voltage (CV) charging. A CC charge is first applied to bring the voltage up to the end-of-charge voltage level. You might even decide to reduce the target voltage to preserve the electrode. Once the desired voltage is reached, CV charging begins and the …
Tracking the active lithium (Li) inventory in an electrode shows the true state of a Li battery, akin to a fuel gauge for an engine. However, non-destructive Li inventory tracking is currently ...
When charging a lithium-ion battery, the charging current, or the amount of electrical energy supplied to the battery, is an important factor to consider. A higher charging current results in a faster charge time, but it can also cause battery damage and shorten its lifespan. To ensure that the battery is charged safely and efficiently, use the proper charging …
