Study on State of Health Estimation Algorithm for Lithium Power Battery Used on Pure Electric Vehicle

摘要

With the continuous development of pure electric vehicles, lithium-ion battery is getting more attention. The SOH is characterized by the capacity of battery charging and discharging, so to meet the national regulations, it is necessary to detect it. This article focuses on estimating the current SOH of the battery based on voltage characterization when charging, and realizes real-time detection of health status in remote monitoring system.
