Résumé
Three main applications of lead acid batteries are starting, lighting and ignition batteries, motive batteries and stationary batteries. Increasing attention to the global climate change and the sustainable development open new applications for the energy storage using lead acid batteries: electric transport, renewable energies such as photovoltaic and wind, grid storage, quality and emergency supplies. In some cases, new applications need new charge algorithms. Various studies were conducted with lead acid batteries in extreme conditions: accelerated charge for vented batteries, maintaining the charge with imposed low current for stationary batteries and deep discharge with polarity inversion. A new charge method for accelerated and fast charges of flooded lead acid batteries was developed. A new method of maintaining the charge with imposed low currents and periodical charges was tested on different technologies of lead acid batteries. It has the advantages of reducing drastically corrosion, of limiting water loss due to corrosion and the need of periodical charges.
