Free QuoteInternal resistance is also a critical index to define state of health (SoH) for lithium ion batteries 3. Cell resistance also has implications for the performance of the entire battery system. Battery systems in applications such as electric vehicles (EVs) employ a large number of cells connected in series and parallel.
The R characteristics refer to the variation of the R varying with different parameters such as the value of SOC (Ssoc), Tamb and charge/discharge rate of the battery. The current researches about the R and thermal characteristics of LIBs mainly focus on the analysis of the influence factors and the establishment of the internal resistance model.
A dynamic model was proposed for lithium-ion batteries DCR based on multiple influencing factors. This model employs a bivariate polynomial of degree four to characterize the relationship between DCR, temperature, and SOC.
Building upon the above analysis, it can be concluded that the primary factors impacting the DCR of lithium-ion batteries include environmental temperature, C-rate, and battery SOC. However, there is currently limited research that comprehensively analyzes the characteristics of battery DCR by considering these three factors.
For a variety of BTM technologies, the battery's internal resistance always plays a critical role in the heat generation rate of the battery. Many factors (temperature, SOC and discharge rate) impact on the internal resistance, however, scant research has explored the effect of battery discharge rate on the internal resistance.
An improved HPPC experiment on internal resistance is designed to effectively examine the lithium-ion battery's internal resistance under different conditions (different discharge rate, temperature and SOC) by saving testing time.
