6 FAQs about [How to control the uniform discharge of battery pack]
How a battery SOC works in discharging mode?
The current control charging wav eforms of the battery SOC, works in discharging mode. The current control discharging wa veforms of the battery source will supply the load. load by discharging. These two cases are modelled separately in this section. Since the batteries are charging in two modes CC and CV.
What happens if a battery pack is not fully charged?
Similarly, the charging of the pack will stop when the in-pack cell with the highest available capacity is full, even though the other cells are still not fully charged. Hence, uneven cells problem will limit the total capacity and remaining available capacity of the pack and thus affect the SOC of the entire battery pack.
How to estimate a battery pack SoC?
Build a method for battery pack SOC estimation. Analyze the effect of the uneven cells problems to the pack SOC. The SOC is estimated with consideration of different balance control strategies. The UPF method is used to estimate the SOC to improve the accuracy. The state-of-charge (SOC) is a critical parameter of a Li-ion battery pack.
