International ClassH02J 007/08Foreign Application Priority Data1992-06-01 FRAbstractA charging apparatus comprising discrete charging circuits each for connection to a different group of cells of an accumulator having multiple groups of cells. Each discrete charging circuit comprises a separate transformer the primary winding of which is connected to a source of an a.c. voltage common to all discrete charging circuits. The secondary winding of each transformer is connected to the input of a rectifier whose output is connected to charging terminals for connection to group terminals of a corresponding group of cells. This arrangement enables the accumulator to be completely charged while substantially reducing the risk of damaging the cell or cells of lowermost maximum capacity.Other References
