Why is SoC management important in EV batteries?
SoC management of EV batteries is an important issue for their performance optimization and lifetime. In view of the urgent need for accurate and fast SOC estimation in EV batteries, new methods have been developed to enhance performance while maximizing battery life.
How does a battery affect the accuracy of SOC estimation?
As a battery ages and its SoH decreases, the accuracy of SoC estimation can be affected. This is because the battery's capacity and voltage characteristics change over time. Capacity fade: As the maximum capacity decreases, the same amount of charge represents a higher percentage of the total capacity, leading to SoC overestimation.
