New, modern designed accumulators offer high performance and efficiency, but also require good care, which among other thing, is the correct charging mode. Today's methods of charging are well able to charge different types of batteries and thus helps to achieve its long service life. If accumulator has to be recharged efficiently, it is usually necessary to control the charging process with respect to the accumulator charge status. In particular, it must checked the temperature, the voltage and current and compensation of voltage drops. Accumulators for hybrid electric vehicles must be able to charge during regenerative braking. Therefore it is used partial charge mode (Partial State of Charge, PSoC) when the accumulator is charged from approximately 50% and receiving electric charge is very efficient even at high charging current. The regime of partial charge leads to undesirable phenomena, which results in a capacity loss. These phenomena are called as PCL (premature capacity loss). However, the issue is not only to accumulators for vehicles operating in the HEV mode. Further areas of use lead-acid accumulators are stand-alone systems and traction applications. In these cases are put high demands on durability, charging rate and simple maintenance.
