Internal resistance and temperature change during over-discharge of lead-acid battery

Internal battery temperature estimation using series battery resistance measurements during cold temperatures

A technique has been developed to estimate the internal battery temperature (Tbat) of secondary batteries by measuring the series battery resistance R ) at cold ambient temperatures. Tests were performed on both lead-acid and nickel metal hydride batteries at different cold temperatures to B btain useful plots of RB versus Tbat. RB was measured by using a pulse discharge circuit to apply a shor...

LabVIEW-based Battery Monitoring System with Effects of Temperature on Lead-Acid Battery

Lead acid batteries are one of the most commonly used batteries. Monitoring the performance parameters of the battery provides essential data useful for managing the batteries efficiently. This paper proposes a highly accurate and efficient battery monitoring system based on NI LabVIEW. As the calculations are done on computer, this system is faster than micro-controller based systems and provi...

Numerical Simulation of a Lead-Acid Battery Discharge Process using a Developed Framework on Graphic Processing Units

In the present work, a framework is developed for implementation of finite difference schemes on Graphic Processing Units (GPU). The framework is developed using the CUDA language and C++ template meta-programming techniques. The framework is also applicable for other numerical methods which can be represented similar to finite difference schemes such as finite volume methods on structured grid...

Kinetic analysis of total Lead from spent Car battery by hydrochloric acid leaching

A study of the kinetic analysis of total lead from spent Car battery ash by hydrochloric acidleaching has been examined. The physico-chemical analysis of the ash powder was carried outby the Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and X–ray diffraction (XRD).The effects of the acid concentration, temperature and particle size on the rate of battery ashdissolution have been investi...
