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.
Does temperature affect battery internal resistance?
The deviation between the two measured values is around 70 m Ω, the lower the battery ambient temperature, the greater the internal resistance value. This finding is consistent with Yang’s study (Lai et al., 2019). Therefore, the temperature is one of the crucial factors which can influence the battery internal resistance. Fig. 5.
