<p class="PaperAbstract"><span lang="EN-GB">In recent decades, more and more electronic systems (start-stop, drive-by-wire, brake-by-wire) have been developed in the automotive industry therefore reliable power sources are necessary. It is essential to understand thoroughly the detailed behavior of the battery to increase its efficiency, stability and monitorability which is the most popular field nowadays. Over-discharge plays an important role in aging because it increases the probability of initiation of grid corrosion, sulfation and loss of active mass. In this work, the effects of over-discharge of lead-acid battery have been investigated via internal resistance increase and temperature change separately for both the negative and the positive electrode. Most of the measurements were carried out in a prepared test cell (which contained a negative and a positive plate, an Ag│Ag<sub>2</sub>SO<sub>4</sub> reference electrode, a shunt for measuring current accurately) connected to a dummy battery and an electronic load.</span></p>

In order to raise the maintenance efficiency of the armored vehicles Lead-Acid battery, this paper introduces an state monitoring system of Lead-Acid battery. The system used the ATMEGA8 as the control core. Through designing measuring circuit of the terminal voltage, internal resistance and temperature as well as building a human-computer interaction user interface using the C++builder, the system can fast and accurately monitors the state of battery. At the same time, we try to use the lock-in amplifying technology to measure the battery inner resistance. The experiment results show that the system easy to use and has a high accuracy.
