The experimental study of lead acid batteries for an electric hybrid drive stand

The paper aims to document a number of experimental tests conducted on some VRLA batteries. A montage scheme is proposed to monitor the behaviour of the batteries on charging and discharging. The results are presented of the measurements of the battery parameters, of the voltage in the open circuit (OCV), as well as the internal impedance, after a process of charging. Based on the catalogue data, the Peukert coefficient and the Peukert capacity are determined, which are used to determine the discharge depth of the batteries tested for the partial discharge. The schema used for discharging ispresented, and also a number of conclusions regarding the testing conditions.
