For simplicity, let''s assume the curve is linear and looks like this:OCV (V)SOC (%)12.610012.05011.60. Allow the battery to rest: We let the battery rest for 1 hour to ensure stable OCV measurement. Measure the open-circuit voltage: We measure the battery''s OCV and find it to be 12.3 V.
One wattmeter measures voltage between the R and T phases, a second wattmeter measures voltage between the S and T phases and a third wattmeter measures voltage between the R and S phases. The phase currents are measured by each wattmeter. The two-wattmeter method is still used to calculate total power. Pt = P1 + P2.

Abstract: As large-scale lithium-ion battery energy storage power facilities are built, the issues of safety operations become more complex. The existing difficulties
The 100 MW Dalian Flow Battery Energy Storage Peak-shaving Power Station, with the largest power and capacity in the world so far, was connected to the grid in Dalian, China, on September 29, and it will be put into operation in mid-October. This energy storage project is supported technically by Prof. Li Xianfeng''s group from the
1. Introduction The energy industry is a key industry in China. The development of clean energy technologies, which prioritize the transformation of traditional power into clean power, is crucial to minimize peak carbon emissions and achieve carbon neutralization (Zhou et al., 2018, Bie et al., 2020).).
