6 FAQs about [Energy storage battery over-discharge current]

How long does a battery stay in a normal discharge stage?

From 0 to 3466 s, the battery stays in the normal discharge stage. In which, the voltage of the battery descends stably until 3224 s; meanwhile, the surface temperature of the battery presents several fluctuations, which is the result of battery heat generation and heat dissipation.

What happens when a battery is discharged at a CC of 1C?

Where, the battery was discharged from 4.2 to 0.2 V at a CC of 1C. As seen, once the battery was discharged to 3.4 V, the voltage and current of the battery exhibited a phenomenon of sharp decline such that the discharging current was quite small when the battery voltage decreased below 0.5 V.

How does over-discharge affect battery degradation?

Besides, it is illustrated that the degradation behaviors of these batteries are identical, regardless of the charge/discharge rates. At the start of over-discharge cycling, the capacities of the batteries degrade quickly, and then the degradation rates remain around 0.05%/cycle.

What happens when a battery is discharged to 3.4 volts?

As seen, once the battery was discharged to 3.4 V, the voltage and current of the battery exhibited a phenomenon of sharp decline such that the discharging current was quite small when the battery voltage decreased below 0.5 V. After that, it was a long-time discharge where the current was near 0 A.

What is a discharge rate in a battery?

Group 3: discharge rate denotes the current rate applied during discharge process. Batteries are charged at a 1C rate, and then discharged at a rate of 0.5, 1, 2 and 3C respectively. Refer to our previous experiment, Fig. 2 can be depicted to show the curves of battery surface temperature, voltage and current during discharge process.

Does cycle rate affect the degradation rate of over-discharged battery?

After the comparison, it can be concluded that the cycle rate has the largest impacts on the degradation rate of the over-discharged battery, while for the charge rate, it is shown that the excessive increase of the charge rate cannot accelerate the degradation continuously, which is the result of the CC-CV charge pattern.
