Strategy of the accelerated mode of the charge of the lead-acid batteries, including constant current charge to 80% state-of-charge and a pulse charge to 100% is considered. Various modes one – and two-stage constant current charges are studied in this work, and the estimation of influence of these modes on effectiveness ratio of a charge and a heat-up of batteries is yielded. The data, which allows reasonably choose the mode of the first stage of the accelerated charge to 80% state-of-charge, are presented.

Electrochemical and corrosion behavior lead, lead-tin and lead-tin-calcium alloys doped with silver and barium was investigated. Composition and structure of passive layers were studied by means of scanning electron microscopy and X-ray analysis.

Strategy of the accelerated mode of the charge of the lead-acid batteries, including constant current charge to 80% state-of-charge and a pulse charge to 100% is considered. Influence of key parameters of a pulse charge (amplitude and duration of charge pulse, duration of a pause, the general duration of a pulse charge) on the efficiency of a charge and a heat-up of batteries are studied in this work.

Present article describes the method of operative diagnostics of available capacity of the lead-acid accumulator (battery) at 10 or 20-h discharge mode. This method is developed on the basis of mathematical model of process of the discharge of the lead-acid accumulator. This allows calculating the available capacity of the accumulator (battery) on the basis of measurement of function of a response to the set short-term test signal without necessity of carrying out the control discharge of the battery.

Method and the resultsof measurementof the internalresistance ofbattery duringitschargeanddischarge are described.It was establishedthat the internal resistance ofthe batteryin operatingvoltage range is almost equallywhencharging and dischargingand does not dependon the current.

We studied the electrochemical deposition of lead dioxide on titanium coated with colloidal graphite. It is showing that under optimal process conditions possible to obtain high quality coatings with good adhesion to the base and high-bit characteristics. Received bit characteristics of the layout of the backup power source.

The influence of porous structure of the absorptive glass mats manufactured by «Hollingsworth&Vose» (thickness 2.8 mm) and BernardDumas» (thickness 3.0 mm), modified by impregnation with polymeric emulsions on the basis of polyvinylidene fluoride (KYNAR), polyvinylpyrrolidone copolymer with styrene (PVS) and polytetrafluoroethylene (Tf), on the efficiency of ionization of hydrogen in lead-acid battery mock-ups. The use of polymer modified emulsions separators from absorbtive glass mat allows to increase the ionization rate of hydrogen on lead-dioxide electrode.
