Texas Instruments uses the Impedance Track method to determine SoC of lead acid batteries . While current off, the OCV is measured, which is used to determine the SoC and to update Q MAX. When discharging, both discharge current and voltage are measured.
Understanding the thermodynamic and kinetic aspects of lead-acid battery structural and electrochemical changes during cycling through in-situ techniques is of the utmost importance for increasing the performance and life of these batteries in real-world applications.
Lead acid batteries are typically used in the automotive industry, where they provide a high current pulse to start the vehicle, in traction applications, where they undergo periodic deep discharge and charge, and in stationary applications, where they remain in charged state most of their life.
Conclusions For the first time, an in-situ electrochemical method is proposed to study the PAM morphological changes inside a functioning lead-acid battery. The method is simple and involves converting Voltage-time plot into DV (δQ/δV vs. Ah) and ICA (δQ/δV vs. V) plots.
Thus, lithium-ion research provides the lead-acid battery industry the tools it needs to more discretely analyse constant-current discharge curves in situ, namely ICA (δQ/δV vs. V) and DV (δQ/δV vs. Ah), which illuminate the mechanistic aspects of phase changes occurring in the PAM without the need of ex situ physiochemical techniques. 2.
