6 FAQs about [Foreign battery pulse test]

What is a pulse test for a battery?

Due to the pulse test condition, the discharge process is required, and the battery needs to be guaranteed to have a certain amount of power. The ideal voltage stage of the pulse test is around 3.4 V (S2) to reach high accuracy of capacity estimation.

How effective is a pulse test for Battery polarization?

Our research also shows that the effectiveness of the model majorly depends on the pulse test, which can reflect the battery's internal resistance as the polarization deepens with the development of aging. Secondly, it is necessary to unify the battery to the same state before the pulse test.

How accurate are pulse tests for lithium ion batteries?

Such pulse tests last for only a few seconds and are convenient to perform in various working conditions of the LIBs. This unique proposed method could reach an overall accuracy of 95% for remaining capacity estimation even for batteries with less than 50% SOH.

Can a pulse test improve battery capacity estimation?

The combined data-driven methods and pulse tests could achieve an average of over 95% accuracy of capacity estimation. Therefore, our efficient and innovative new pulse test integrated with the data-driven algorithm could open up a new window for fast estimation of the remaining battery capacity.

What is a pulse test?

The pulse tests were done from 90-10% SOC with 40 pulses of 30A with the length of 20 seconds at each SOC point, an example of a pulse can be seen in figure 14 with a length of 120 seconds. For this measurement, the battery cell was charged to 100% SOC and then discharged 10-20% depending on SOC level for each measurement.
