The hardware structure of a liquid level detection system for lead-acid battery was briefly introduced. The system adopts AT89C51 MCU as host module, combined with display storage, extended storage and the watch dog technology. The slave module adopts AT89C2051 MCU, which driver the linear CCD to realize non-contact measurement in acidic and corrosive conditions. The infrared transmission module uses RS-232 serial-to-infrared technology to realize wireless data delivery. The damage due to sensor corrosion could be avoided in this system. Compared with other similar equipments, this system has the advantages of simple structure, small volume, low cost, high measure precision and convenient maintenance.

<p>Due to its low cost and recycle-ability, the lead-acid battery is widely used in mobile and stationary applications. Despite much research on lead-acid batteries, the effect of charging voltage on the degradation mechanism requires further investigation. In particular, the origin of cycle life degradation remains unclear. In the present work, by using electrochemical tests and materials characterization, we studied the effect of charging voltage at voltages slightly higher than the open-circuit potential (OCP) i.e., 103-107% OCP, on the battery life cycle. The highest degradation was observed at 105% OCP charging voltage. Based on the materials characterization results, we found that the degradation of a lead-acid battery is influenced by the amount of hard sulfate and the sulfate particles' size.</p>

Lead Acid Batteries (LABs) are used for starting, lighting, igniting, air conditioning systems and supplying power to electric engines in Transport Vehicles (TVs). However, the application of LABs for TVs has faced a number of market challenges mounted by the upcoming high energy density and long lifespan batteries such as Lithium Ion. LABs on the other hand are low cost. The key research question is, how can the lifespan of LABs used in automotive industries be increased, while still ensuring a low cost solution? Thus, integrating LABs with the Supercapacitor is likely to outperform the competing alternative batteries for TVs. This paper proposes a multiple stage approach to hybrid Lead Acid Battery and Supercapacitor&nbsp;system for TVs that is capable of maintaining the battery State-of-Charge (SOC) to statistically high limits ranging between 90% and 95%. This SOC target will likely ensure that the lifespan of the hybrid battery system can be elongated (extended) more than its competitors. In this study, the multiple stage approach of concatenated converters has been designed in order to satisfy all energy storage requirements for different characteristics of LAB and Supercapacitor. The designed hybrid system has been simulated using Matlab/Simulink. The simulated results show that high transient currents from the DC Bus of LAB caused by the regenerative braking or deceleration of the TVs reduces the battery lifespan and induce mechanical stress. Supercapacitor reduces the stress on the LAB by absorbing high transient currents. This, in turn keeps the LABs&rsquo; SOC between 90-95% and the voltage at 12V. As&nbsp;indicated by the simulated results, the hybrid battery SOC is maintained at 90-93% and the terminal voltage is approximately 12V.

Storage battery is an indispensable energy storage device at present. It is widely applied to industries like electric automobiles due to its advantages such as safety, reliability, low cost, etc. However, like most storage batteries, lead-acid battery has a series of problems in the low temperature environment such as the plunge of capacity, difficulty of charge, and so on, which deeply influence its application effect. To improve the low temperature performance of lead-acid battery, carbon materials could be added to the cathode of lead-acid battery. By measuring the properties like HRPSoC cycle and dynamic charging under different carbon (graphite) content, this article concludes that the addition of carbon material could improve the low-temperature performance of lead-acid battery. When the carbon content is between 0.3% and 0.9%, the improvement effect is relatively better. The research result of this article has a reference function to the design and development of low-temperature lead-acid batteries.
