Experimental and Numerical Study of Small Lead Acid Batteries Regeneration

Battery ageing and performance evolution prediction is one of the energy management key. The use of lead acid batteries is always strong despite its weight and the constant increasing, of new battery materials and technologies. The lead acid batteries are mainly used to start car engine or as primary energy source for forklift or pallet trucks. Another application is the storage of electrical energy produces by intermittent energy sources like photovoltaic, wind or tidal powers. Multiple factors influence lead acid batteries ageing depending of the type of batteries technology (vented or opened and VRLAB or sealed) and the kind of use. We focus our experimental study on four of them: the number of ageing cycles (1), the operating current (2), the temperature (3) and the use of electrolyte additives, containing EDTA (4). Factors are investigated on two levels (Table 1). Figure 1
